All are factors to consider when planning a farmstead except?

Answer Details

Irrigation is not a factor to consider when planning a farmstead because it is not a requirement for a farmstead. A farmstead refers to a farm and the buildings and other structures on the farm, such as a house, barn, and outbuildings. Accessibility, topography, and soil type are all important factors to consider when planning a farmstead because they can impact the type of crops or livestock that can be raised on the farm, as well as the design and placement of buildings and other structures. Accessibility refers to the ease of getting to and from the farm, which can impact the transportation of goods and people. Topography refers to the natural features of the land, such as hills and valleys, which can impact the placement of buildings and the type of crops that can be grown. Soil type refers to the type of soil on the farm, which can impact the type of crops that can be grown and the fertility of the soil.

In which of the soil layer does most biological activity occur?

Answer Details

Most biological activity in soil occurs in the A-horizon. The A-horizon, also known as the topsoil, is the uppermost layer of soil that is composed of a mixture of mineral particles, organic matter, and living organisms. This layer is particularly rich in organic matter, which provides a food source for microorganisms such as bacteria and fungi that play a vital role in breaking down organic materials and releasing nutrients that plants can use for growth. Additionally, the A-horizon is where plant roots grow and interact with soil organisms, which can influence the health and productivity of both plants and soil. Therefore, the A-horizon is considered the most biologically active layer of soil.

Answer Details

The pox disease in livestock are caused by "viruses". Pox diseases are a group of viral infections that affect livestock, including cattle, sheep, and goats. These diseases are highly contagious and can spread rapidly through populations of animals, causing skin lesions, respiratory symptoms, and, in severe cases, death. Bacteria, protozoa, and fungi are not the cause of pox diseases in livestock. Bacteria are single-celled microorganisms that can cause a wide range of diseases in livestock, but they are not responsible for pox diseases. Protozoa are single-celled organisms that can also cause diseases in livestock, but they are not the cause of pox diseases. Fungi are multicellular organisms that can cause infections in livestock, but they are not the cause of pox diseases.

In animal nutrition, iodine is essential for the production of

Answer Details

Iodine is essential for the production of thyrozine, which is a hormone produced by the thyroid gland. The thyroid gland is a small butterfly-shaped gland located in the neck. Thyrozine helps regulate the metabolism of animals and other organisms, which is the process by which they use energy from food to carry out their daily activities. Iodine is important because it is a key component of thyrozine. Without enough iodine, the thyroid gland cannot produce enough thyrozine, which can lead to a variety of health problems, including a slow metabolism and weight gain. In conclusion, iodine is an essential nutrient for animals, and it is important for the production of the hormone thyrozine, which helps regulate metabolism.

The Head of the tapeworm is known as the

Answer Details

The head of a tapeworm is known as the "scolex". The scolex is the attachment organ of the tapeworm that enables it to attach to the host's intestinal wall. It is a small, flattened structure that contains suckers and hooks, which the tapeworm uses to hold onto the intestine. The rostellum is a structure found on some tapeworms that helps them attach to the host's intestinal wall, but it is not the same as the scolex. Therefore, the correct answer is "scolex" when referring to the head of a tapeworm.

Answer Details

The most unreliable source of power on the farm is wind. This is because wind is a highly variable and unpredictable resource that can change in strength and direction quickly. Unlike other sources of power, such as electricity or heat engines, which are more consistent and controllable, wind power is subject to the whims of nature and can't be relied upon to provide consistent and reliable power for farming operations. Additionally, wind turbines require a minimum wind speed to generate power, and in calm weather conditions, they may not produce any power at all.

One major difference between disc plough and disc harrow is

Answer Details

The main difference between a disc plough and a disc harrow is their purpose and how they interact with the soil. A disc plough is used to turn over and break up the soil to create furrows for planting crops, while a disc harrow is used to break up clumps of soil, level the ground, and prepare it for planting by chopping up weeds, roots, and plant residue. The disc part of a plough is notched, which helps it to cut through the soil, while the disc part of a harrow is round, which allows it to smooth out the soil surface.

All but one are qualities of a good extension worker

Answer Details

Out of the four options, "Involvement in local politics" is not a quality of a good extension worker. An extension worker is a professional who helps farmers and rural communities to adopt new technologies and improve their agricultural practices. To be effective in this role, an extension worker should have certain qualities, such as: - Organizational Ability: The ability to plan and carry out activities efficiently, and to manage resources effectively. - Clear Judgement: The ability to analyze information, make sound decisions, and provide advice to others. - Initiative: The ability to take the lead in solving problems and identifying opportunities for improvement. Involvement in local politics is not a quality of a good extension worker because extension workers should maintain impartiality and not align themselves with any particular political party or interest group. They should be focused on providing impartial and evidence-based advice to support the development of the rural communities they serve.

Which one of these is not part of a disc plough?

Answer Details

Planter is not part of a disc plough. A disc plough is a farm implement that is used for primary tillage to break up and loosen soil in preparation for planting. It typically consists of a series of individual discs, which are arranged in a line and mounted on a frame. The coulter is a vertical blade that cuts through the soil and creates a furrow for the discs to follow. The discs themselves are typically concave and have a sharp edge, which slices through the soil and turns it over. The furrow wheel follows behind the discs and helps to control the depth of the ploughing. The disc scraper is a blade or bar that is attached to the frame of the plough and helps to prevent the discs from becoming clogged with soil or debris. It is typically positioned behind the discs and scrapes away any material that may be caught between them. Therefore, the planter is the option that is not part of a disc plough. A planter is a separate implement that is used for planting seeds or seedlings into the soil, and is not typically integrated into the design of a disc plough.

Answer Details

Phalaris minor is a species of grass native to North Africa, Europe, and South Asia. The bunchgrass is widely naturalised elsewhere. Common names include little seed canary grass, small-seeded canary grass, small canary grass, lesser-canary grass, guli danda (Hindi), and sittee booti (Urdu). Phalaris minor is a crop associated with wheat. Choice A is correct.

The non-oil crop among the following is

Answer Details

Cowpea is the non-oil crop among the following. While coconut, beniseed (sesame), and melon are all oil crops that are grown primarily for their oil-rich seeds, cowpea is a legume crop that is grown for its edible seeds, which are rich in protein and other nutrients. Cowpea is commonly consumed as a food crop in many parts of the world, and it is also used as a forage crop for livestock. Unlike coconut, beniseed, and melon, which are all highly valued for their oil content, cowpea is not typically grown for oil production. While it does contain some oil, the oil content of cowpea seeds is relatively low compared to oil crops like coconut and beniseed. Instead, cowpea is grown primarily for its nutritional value and as a source of protein for human and animal consumption. So, of the options given, cowpea is the non-oil crop, as it is not primarily grown for its oil content.

Which of the following cereal crops most requires nursery practices?

Answer Details

Rice is the cereal crop that most requires nursery practices. Rice is typically started from seed in a controlled nursery environment before being transplanted to the field. This process is known as "direct seeding" and it involves sowing the rice seeds in a seedbed or nursery, where they can be carefully tended and protected from pests and other threats until they are strong enough to be transplanted. Nursery practices for rice can include things like preparing the seedbed, selecting high-quality seeds, managing water and nutrients, controlling pests and diseases, and ensuring proper spacing between seedlings. Once the seedlings have grown to a certain size and are strong enough to withstand transplanting, they are carefully uprooted and moved to the main field. While other cereal crops like maize, millet, and guinea corn can also benefit from certain nursery practices, they are typically started directly in the field through methods like broadcasting or drilling. Rice, on the other hand, is more commonly transplanted from a nursery, making it the cereal crop that most requires nursery practices.

Soil texture can be refered to as

Answer Details

Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method. Soil Texture is the classification of soil based on its physical texture and characteristics, particularly the size of the particles that make up the soil.

Which one of these is not an advantage of newspaper as agricultural extension teaching methods?

Answer Details

Extension teaching methods are the tools and techniques used to create situations in which communication can take place between the rural people and the extension professionals. These are the methods of imparting new knowledge and skills to the rural people by drawing their attention towards such technologies, thereby arousing their interest and helping them to have a successful experience of the new practice. Newspaper can only be read by the literate farmers and majority of the farmers are ILLITERATE.

Blast of rice is a

Increase in farm produce is not usually improved by the

Answer Details

The option that is not usually related to an increase in farm produce is "improved sales of crop and livestock." Improved sales refer to better marketing and selling strategies, which can result in higher profits, but it does not directly increase the quantity of farm produce. On the other hand, the use of improved crop varieties, increased use of manure and fertilizer, and use of better farm equipment and tools are all factors that can contribute to an increase in farm produce. Improved crop varieties have traits that are better adapted to the local growing conditions, such as resistance to pests and diseases, or tolerance to drought or floods. Increased use of manure and fertilizer helps to improve soil fertility and nutrient levels, which can increase the yield and quality of crops. Better farm equipment and tools can make the farming process more efficient, allowing farmers to cultivate larger areas in less time and with less labor. Therefore, to summarize, the option that is not usually improved by an increase in farm produce is "Improved sales of crop and livestock", as it refers to better marketing strategies and does not directly increase the quantity of farm produce.

The demand for agricultural produce is generally

Answer Details

Demand for most farm products is inelastic. People can consume only so much then they are satiated. Even if price drops they will not buy much more. When demand is inelastic a drop in price that spurs more quantity being sold results in lower revenue and profit for the producer.
Choice B is correct. A price inelastic demand would mean that an increase in price would not necessarily lead to a decline in quantity demanded or in case it does proportion of quantity change would be lesser vis a vis the change in price.
Demand tends to be price inelastic for agricultural produce for the following reasons.
1. Price changes don't affect consumption much
2. These produce are mostly necessities
3. Possibility of postponement is not there for most of these produce

Which one of these is not a factor that affect change in supply of agricultural produce?

Answer Details

Fixed cost is the option that does not affect the change in supply of agricultural produce. Fixed costs are the expenses that do not change with changes in the level of output or production, such as rent or salaries. In contrast, factors that affect the change in supply of agricultural produce are those that influence the quantity of goods that farmers are willing and able to produce and sell in a given period of time. Technology can increase the efficiency and productivity of agricultural production, leading to an increase in supply. Changes in the cost of production, such as changes in the price of inputs like fertilizer or labor, can affect the profitability of farming and impact the supply of agricultural produce. Changes in commodity prices can also affect the supply of agricultural produce, as farmers may be more willing to produce more goods if they can sell them at higher prices. In summary, while fixed costs are an important consideration in farming and agricultural production, they do not directly affect the change in supply of agricultural produce.

Which of the following is a type of land tenure system?

Answer Details

The type of land tenure system is the freehold system. The freehold system is a type of land tenure system in which an individual or entity owns the land outright and has the right to use, occupy, and sell the land as they see fit. This type of system is common in many countries around the world, including the United States, Canada, and Australia. Under the freehold system, the owner of the land has complete control over it, and can use it for any legal purpose, such as agriculture, residential or commercial development, or conservation. The owner is also responsible for paying property taxes on the land and any structures or improvements that are built on it. This system is different from other types of land tenure systems, such as leasehold or communal systems, where individuals or groups have limited rights to use or occupy the land, and ownership may be held by a government entity or a community as a whole. Overall, the freehold system is designed to provide individuals or entities with secure and exclusive rights to use and manage the land, which can encourage investment, development, and long-term planning.

Which of the following requires Silicon (Si) for its growth?

Answer Details

Out of the given options, none of them directly requires Silicon (Si) for their growth. However, some plants can benefit from having Silicon available in their environment, and may grow better and healthier as a result. Silicon is not an essential nutrient for plants, meaning that they can grow without it. However, some research suggests that Silicon can improve plant growth, especially in harsh environmental conditions like drought, high salinity, and pests or diseases. Of the plants listed, Rice is one of the crops that has been shown to benefit significantly from Silicon supplementation. This is because Rice is a heavy user of Silicon, which it takes up and accumulates in its tissues, contributing to the structural stability of the plant and enhancing its resistance to pests and diseases. In summary, while none of the given plants require Silicon for their growth, Rice is one of the crops that can benefit from it. However, it's important to note that Silicon is not a magic bullet for plant growth and should be used in conjunction with other best practices for plant health and productivity.

Which of the following is not a branch of agriculture?

Answer Details

The option "Kidding" is not a branch of agriculture. Agriculture is the science, art, and business of cultivating land, raising crops, and raising livestock for food, fuel, and other products. Agriculture includes many branches such as agronomy, horticulture, animal husbandry, and agricultural economics, among others. Forestry is the science of managing and conserving forests, including the study of trees, woodlands, and their ecosystem. Fishery is the study and management of fish and other aquatic species for commercial, recreational, and conservation purposes. "Kidding" is not a recognized branch of agriculture and is not related to the field.

The main mode of infection of rinderpest disease in cattle is through

Answer Details

The main mode of infection of rinderpest disease in cattle is through inhalation. Rinderpest is a viral disease that affects cattle and other cloven-hoofed animals. The virus is highly contagious and can spread rapidly through herds. The virus is shed in large amounts in nasal and ocular discharges, saliva, and feces of infected animals, which can contaminate the environment and infect other animals. Inhalation of the virus occurs when healthy animals breathe in the virus from the air or from contaminated surfaces, such as feed and water troughs or fences. The virus can survive for several days in the environment, which means that even if an infected animal has been removed from a location, the virus can still be present and infect other animals. While grazing and drinking contaminated water can also lead to infection, inhalation is the primary mode of transmission for rinderpest. The virus can also be spread through contact with contaminated objects or through the handling of infected animals, but these modes of transmission are less common compared to inhalation. In summary, the main mode of infection of rinderpest disease in cattle is through inhalation of the virus, which can be present in the air or on contaminated surfaces.

Maize grows best on

Answer Details

Maize grows best on loamy soil. Loamy soil is a mixture of sand, silt, and clay, and is considered one of the best soil types for growing crops like maize. This is because loamy soil has a balanced mix of particles that allows it to hold water and nutrients well while also providing good drainage. The balance of sand, silt, and clay in loamy soil allows for good aeration, which is important for healthy root growth in maize plants. Sandy soil, on the other hand, has larger particles that do not hold water or nutrients well and can lead to poor crop growth. Sandy-clay soil and silty-clay soil have higher clay content, which can lead to poor drainage and waterlogging in wet conditions, making them less suitable for growing maize. In summary, maize grows best on loamy soil, which has a balanced mix of sand, silt, and clay that provides good drainage, aeration, and nutrient holding capacity for healthy crop growth.

The following are the advantages of the sprinkler method of irrigation except

Answer Details

The advantages of the sprinkler method of irrigation include the fact that the system can be made automatic, they are portable making them suitable for use, and the rate of application of irrigation water can be controlled. However, one disadvantage of the sprinkler method is that it may be difficult for local farmers to use. The sprinkler method of irrigation involves spraying water onto the crops from above, using a system of pipes and nozzles. This method is beneficial because it allows for water to be distributed evenly over the crops, which helps to ensure that each plant receives an adequate amount of water. The system can also be made automatic, which means that it can be set to turn on and off at specific times, making it a convenient option for farmers. Additionally, the portability of the sprinkler system makes it suitable for use in a variety of settings, including fields, gardens, and lawns. Farmers can easily move the sprinkler system from one area to another, allowing them to irrigate different parts of their land as needed. The rate of application of irrigation water can also be controlled with the sprinkler method. This means that farmers can adjust the amount of water that is applied to their crops, depending on factors such as weather conditions and the stage of growth of the plants. However, one disadvantage of the sprinkler method is that it may be difficult for local farmers to use, especially if they lack the technical knowledge and skills required to install and maintain the system. Additionally, the cost of setting up a sprinkler system may be prohibitive for some farmers, which can limit its accessibility.

Which of the following is not a breed of rabbits?

Answer Details

Land race is not a breed of rabbits. Landrace is actually a breed of domestic pigs that originated in Denmark, and is known for its good maternal instincts and high fertility. New Zealand White, Chinchilla, and Californian White, on the other hand, are all breeds of rabbits. New Zealand White is a breed that is commonly used for meat production, while Chinchilla is a breed that is valued for its soft and dense fur. Californian White is a breed that was developed in the United States, and is also commonly used for meat production. Therefore, Land race is the option that is not a breed of rabbits, but rather a breed of domestic pigs.

What is crop rotation?

Answer Details

Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and yield crop. Choice A is correct. Crop rotation involves the growing of crops one after other in a particular sequence

Oil palm trees do well in soils with pH level of

Answer Details

Oil palm trees do well in soils with a pH level between 5.5 and 6.5. Soil pH is a measure of the acidity or alkalinity of the soil, and it affects the availability of nutrients to plants. The pH scale ranges from 0 to 14, with a pH of 7 considered neutral. Values below 7 are considered acidic, and those above 7 are alkaline. Oil palm trees have specific nutrient requirements, and the availability of these nutrients can be affected by soil pH. Soils with a pH level between 5.5 and 6.5 are considered slightly acidic to neutral, which is optimal for oil palm growth and production. In soils that are too acidic or alkaline, certain nutrients may be unavailable to the plant, leading to nutrient deficiencies and reduced yields. It's worth noting that different soils have varying levels of acidity or alkalinity, and it's important to test the soil pH level before planting oil palm trees to ensure the soil is suitable for the crop. Soil pH can be adjusted through the application of soil amendments such as lime to increase the pH or sulfur to decrease the pH, depending on the specific needs of the soil and the crop.

Which of the following nutrient element is not a micro-nutrient

Answer Details

Calcium is not a micro-nutrient. Nutrients required by plants for growth and development can be classified into two categories: macro-nutrients and micro-nutrients. Macro-nutrients are nutrients that are required in larger amounts by plants, while micro-nutrients are required in smaller amounts. Calcium is a macro-nutrient that is essential for plant growth and development. It is required in relatively large amounts and plays an important role in cell wall formation, root development, and the regulation of other nutrients in the plant. In contrast, Iron, Manganese, and Boron are micro-nutrients that are required by plants in smaller amounts. These micro-nutrients are important for various functions in the plant, such as photosynthesis, enzyme activation, and hormone regulation. Therefore, Calcium is not a micro-nutrient because it is required in larger amounts by plants compared to micro-nutrients like Iron, Manganese, and Boron.

Fertilizer application in maize should be completed before

Answer Details

Fertilization or fertilizer application is the supplemental application of plant nutrients to crop plants to augment the supply from natural sources. This consists of applying nutrient-containing materials, called fertilizers, generally into the soil in proximity to receptor plants.

Which of the following nutrient is highly immobile in plants?

Answer Details

Mobile nutrients are nitrogen in the form of nitrate, phosphorus (P) in the form of phosphate, potassium (K), magnesium (Mg), chlorine (Cl), zinc (Zn) and molybdene (Mo). Calcium (Ca), sulfur (S), iron (Fe), boron (B) and copper (Cu) are immobile. Boron (B) is highly immobile because of its size. Therefore, choice A is correct.

Some of the by-products of fish include the following except

Answer Details

The by-product of fish that is not on the list is "leather." Fish can be a valuable source of various by-products that are useful in various industries. For example, fish can be processed into fish meal, which is a high-protein feed ingredient used in animal feed production. Fish oil is another by-product that is commonly extracted from fish, which has a wide range of applications in the food, pharmaceutical, and cosmetic industries. Fish silage is another by-product that is produced when fish waste is ensiled, which can then be used as a fertilizer or feed ingredient. However, leather is not a by-product that is typically associated with fish. Leather is usually made from the skin or hide of animals such as cows, sheep, and goats. Therefore, leather is not a by-product of fish. In summary, while fish can be processed into a range of useful by-products like fish meal, oil, and silage, leather is not one of them.

Which of the following is not a source of minerals in animal nutrition?

Answer Details

Minerals essential for animal life include common salt (sodium chloride), calcium, phosphorus, sulfur, potassium, magnesium, manganese, iron, copper, cobalt, iodine, zinc, molybdenum, and selenium. The last six of these can be toxic to animals if excessive amounts are eaten. Palm oil not a source of minerals in animal nutrition.

Reduction of ten seedlings of maize to two per stand is referred to as

Answer Details

The reduction of ten seedlings of maize to two per stand is referred to as Thinning. Thinning is the process of removing some of the weaker or excess seedlings in a plant stand to allow the remaining plants to have enough space, light, and nutrients to grow properly. This helps to ensure that each plant has enough resources to reach maturity and produce a good yield. In the case of maize seedlings, if there are too many plants growing in close proximity, they may compete with each other for resources, leading to smaller and weaker plants. By thinning the stand down to two seedlings per stand, you are providing the remaining plants with the necessary resources they need to grow strong and healthy.

Dura, Tenera and Pisifera are all cultivated varieties of

Answer Details

Dura, Tenera, and Pisifera are all cultivated varieties of oil palm. Oil palm is a type of palm tree that is grown for its fruit, which contains a high amount of oil that is used for cooking and in many other products. The three varieties, Dura, Tenera, and Pisifera, are all different in their physical characteristics and the amount of oil they produce. 1. Dura: This variety of oil palm has thick-shelled fruit with a relatively low oil content. It is commonly used as a rootstock for grafting other varieties onto. 2. Tenera: This variety is a hybrid between Dura and Pisifera and is the most commonly cultivated variety of oil palm. Its fruit has a thinner shell and higher oil content compared to Dura. 3. Pisifera: This variety has thin-shelled fruit and a high oil content, but it is less commonly cultivated than Tenera because its fruit is prone to damage and disease. In summary, Dura, Tenera, and Pisifera are all cultivated varieties of oil palm that have different physical characteristics and oil content. Tenera is the most commonly cultivated variety because it has the best balance of fruit quality and oil content.

The type of labour available to peasant farmers is

Answer Details

Peasant farming is a type of farming that is practised by peasant farmers on small farm holdings. The labour is mostly supplied by the farmer and his family. The type of labour available to peasant farmers is family labour because most peasant farmers practise subsistence agriculture. Choice A is correct.

Crops grown primarily for feeding animals are known as

Answer Details

Crops grown primarily for feeding animals are known as forage. Forage crops are grown specifically to be used as animal feed, either by grazing animals directly on the pasture or by harvesting the forage and feeding it to animals as silage or hay. Forage crops can include grasses, legumes, and other plants that are high in fiber and provide the necessary nutrients for animal growth and development. These crops can be grown for a variety of animals, such as cattle, sheep, goats, and horses. Vegetables, cereals, and shrubs, on the other hand, are not primarily grown for feeding animals. Vegetables are grown for human consumption, while cereals can be grown for both human consumption and animal feed. Shrubs, although they can be used as animal feed in some cases, are typically not grown specifically for this purpose. Therefore, forage is the term used to describe crops that are grown primarily for feeding animals.

Which one of the following is not a target group of an agricultural Extension agent

Answer Details

The target groups of an agricultural Extension agent are typically individuals or groups who are involved in agriculture or rural development. These can include farmers, rural youth, women's groups, agribusinesses, cooperatives, and others who are engaged in agricultural activities. Of the options given, the one that is not a target group of an agricultural Extension agent is political parties. Political parties are not directly involved in agricultural activities or rural development, and therefore would not typically be a target group for agricultural Extension services. Extension agents are typically tasked with providing education, training, and other forms of support to help farmers and rural communities improve their productivity, sustainability, and economic well-being. They may work with individual farmers or groups, providing information and guidance on topics such as crop and livestock management, pest and disease control, soil fertility, marketing, and other issues that can affect agricultural productivity and profitability. So, the correct answer is political parties.
