The main objectives of agriculture is
Answer Details
The main objectives of agriculture are food production, income generation, and provision of employment. Food production refers to the growing of crops and raising of livestock for the purpose of feeding people. Agriculture is the main source of food for most populations around the world and plays a crucial role in ensuring food security. Income generation refers to the use of agriculture as a means to earn money. This can be achieved through the sale of crops, livestock, and other agricultural products. Agriculture provides a source of livelihood for millions of people, particularly in rural areas. Provision of employment refers to the creation of job opportunities in the agricultural sector. This includes jobs in farming, processing, and other related industries. Agriculture can help to reduce unemployment, especially in areas where there are limited job opportunities. The objective of provision of shelter is not typically considered one of the main objectives of agriculture. Although, agriculture can play a role in providing materials for building homes, such as wood and other natural resources, the primary focus of agriculture is on food production, income generation, and employment.
Question 2 Report
In subsistence agriculture
Answer Details
In subsistence agriculture, surplus produce is small and savings are not made. Subsistence agriculture is a type of agricultural system in which farmers grow food primarily for their own consumption and for the consumption of their families and communities. In subsistence agriculture, farmers typically have limited resources and technology, and the focus is on producing enough food to meet basic needs, rather than producing a surplus for sale or trade. As a result, the surplus produce from subsistence agriculture is typically small, and farmers do not have the resources or market access to make savings or investments. Instead, they focus on producing enough food to feed themselves and their families. Farm sizes in subsistence agriculture can vary, and may range from small plots of land to larger holdings. The main focus is on producing enough food to meet basic needs, rather than maximizing production and profits. So, the answer to the question is surplus produce is small and savings are not made.

Answer Details
The main processes involved in the marketing of cotton do not include wedding. Wedding is not a process that is typically associated with the marketing of cotton. The marketing of cotton typically involves several key processes, including processing, grading, and packaging. Processing involves cleaning and preparing the cotton fibers for use in various products. This may include spinning the cotton into yarn or thread, and weaving or knitting the cotton into fabric. Grading involves evaluating the quality of the cotton fibers and sorting them into different grades based on factors such as length, strength, and color. This helps to ensure that the cotton fibers are used in the most appropriate applications and that customers receive the best quality products. Packaging involves packaging the cotton fibers or products made from cotton into bags or other containers for storage and transportation. This helps to protect the cotton from damage and contamination during transit and storage, and makes it easier for customers to handle and use the cotton in their own operations.
Question 4 Report
The system in which a farmer uses a piece of land for a period and abandons it for another land is called
Answer Details
The system in which a farmer uses a piece of land for a period and abandons it for another land is called "shifting cultivation". In this system, a farmer will clear a piece of land for farming, use it for a few seasons until the soil becomes less fertile, and then move on to another piece of land and repeat the process. This allows the abandoned land to recover its fertility and biodiversity. Shifting cultivation is often used by small-scale farmers in tropical regions where the soil is less fertile and where there are few other options for agriculture.
Question 5 Report

Answer Details
The study of insect pests of crops is called entomology. Entomology is the scientific study of insects, including their biology, behavior, evolution, and ecological relationships. Within entomology, there is a subfield that focuses specifically on insects that cause harm to crops, livestock, and other agricultural products. This subfield is called agricultural entomology and it focuses on the study of insect pests and their management. Pathology is the study of diseases and their causes, while agronomy is the science and technology of producing and using plants for food, fuel, and other products. Synecology is the study of ecological communities and their interactions. So, the answer to the question is entomology.
Question 6 Report
Subsistence agriculture is characterized by
Answer Details
Subsistence agriculture is characterized by small farm holdings and the production of food for the farmer's own use and consumption. Subsistence agriculture is a type of farming that is practiced on a small scale and is focused on providing food and basic necessities for the farmer and their family, rather than producing crops for sale or trade. Subsistence farmers typically cultivate small plots of land and use simple tools and techniques to grow crops and raise animals. In contrast, large scale agriculture is characterized by the use of machines and intensive use of inputs, such as fertilizers and pesticides, to maximize production and increase profits. While subsistence agriculture can provide food security for the farmer and their family, it can also result in low yields and limited economic opportunities. On the other hand, large scale agriculture can be more efficient and profitable, but can also lead to environmental degradation and social inequalities.
Question 7 Report
Callosobruchus maculates is a common pest of
Answer Details
Callosobruchus maculatus is a common pest of cowpea. Cowpea is a type of bean that is widely grown and consumed in many parts of the world. Callosobruchus maculatus is a tiny beetle that feeds on the seeds of the cowpea plant. This insect can cause serious damage to the crop, reducing the yield and quality of the beans. The beetle lays its eggs on the surface of the cowpea seeds, and when the eggs hatch, the larvae burrow into the seed and start feeding on it. This feeding can damage the seed and make it unviable, reducing the yield of the crop.
Question 8 Report
An advantage of extensive system of rearing goats is
Answer Details
An advantage of an extensive system of rearing goats is low labor requirement. This means that in an extensive system, goats are allowed to graze and forage for their own food in a natural environment, with minimal human intervention. This can result in a lower cost of production as there is less need for expensive feed and fewer inputs required for maintenance. Additionally, this system can also be less time-consuming for the farmer, as there is less need for daily chores such as feeding and cleaning.

Question 10 Report
The practice of mating closely related animals is called
Answer Details
The practice of mating closely related animals is called inbreeding. Inbreeding is when two animals that are closely related, such as siblings or parent and offspring, are bred together. This increases the likelihood that their offspring will have similar traits and characteristics because they share many of the same genes. While inbreeding can lead to the expression of desirable traits, it can also increase the risk of genetic disorders and other health problems. For this reason, many breeders prefer to use outbreeding, or mating animals that are not closely related, to promote genetic diversity and reduce the risk of health problems in their offspring.
Question 11 Report
The adult male cattle is called
Answer Details
The adult male cattle is called a bull. A bull is a mature male bovine animal that is used for breeding and producing offspring. Bulls are typically larger and stronger than female cattle, and they have distinctive characteristics such as large horns and a muscular build. A ram is a male sheep, while a boar is a mature male pig. These animals are not called bulls, as they are not bovine animals. A duck is a type of bird, and it is not related to cattle or other domesticated farm animals.
Question 12 Report
Which of the following fishing gears can be used for total harvesting of pond?
Answer Details
A dragnet can be used for total harvesting of a pond. A dragnet is a type of fishing gear that consists of a large net that is pulled through the water by a boat or by people on the shore. The net is designed to catch all types of fish in the pond, making it an effective way to harvest a large quantity of fish in a short amount of time. Hook and line and harpoon fishing gears are typically used for catching specific types of fish, rather than for total harvesting of a pond. Basket traps are often used to catch crustaceans and other small aquatic animals, rather than fish. While dragnet fishing can be an effective way to harvest a large quantity of fish, it can also have negative impacts on the ecosystem if it is not managed properly. Overfishing and destruction of habitats can result if dragnet fishing is not regulated and monitored.
Question 13 Report

Answer Details
Fertile soil is one that contains all essential plant nutrients in suitable proportions. Fertile soil is rich in nutrients, such as nitrogen, phosphorus, and potassium, that are essential for plant growth and development. It also contains other important minerals and organic matter that support the health of the soil and the plants growing in it. A soil that is fertile will produce a good harvest of crops, including cowpea, because the plants are able to access the nutrients they need to grow strong and healthy. In addition to being rich in nutrients, fertile soil is also well aerated and easily drained, which allows the roots of the plants to access air and water, two critical components of healthy plant growth.
Question 18 Report
The most common factor affecting land use is
Answer Details
The most common factor affecting land use is population pressure. This means that as the number of people in an area increases, there is a greater demand for land to be used for residential, commercial, and industrial purposes. This pressure can lead to changes in land use, such as the conversion of farmland to urban areas, deforestation, and the development of new infrastructure. In simple terms, as the population grows, the demand for land increases, and this affects how the land is used.
Question 19 Report

Answer Details
The average weather condition of a place, measured over a long period of time, is called climate. Climate refers to the long-term patterns of temperature, precipitation, wind, and other meteorological conditions in a specific region. Climate is different from weather, which is the condition of the atmosphere at a specific time and place. Climate is determined by a variety of factors, including the geography of a region, its distance from the equator, and the prevailing winds and ocean currents. Climate is a complex system and it can take many years of data and observation to understand it completely. Understanding a region's climate is important for a variety of reasons, including agriculture, transportation, and energy production.
Question 21 Report
Which of the following is not a method of improving rangeland?
Answer Details
The following is not a method of improving rangeland: regular application of fertilizers. Improving rangeland involves managing the land in a way that promotes the growth of desirable vegetation and reduces the impact of undesirable vegetation. One of the methods of improving rangeland is practicing continuous grazing, which involves rotating animals from one area to another to prevent overgrazing and allow the vegetation to recover. Routine and regular weeding involves removing unwanted plants that compete with the desirable vegetation for water, nutrients, and light. Routine reseeding involves replanting desirable vegetation that has been lost due to natural causes or overgrazing. While regular application of fertilizers can be important for improving the quality of cultivated crops, it is not a method of improving rangeland. In many cases, applying fertilizers to rangeland can actually have negative impacts, such as altering the natural balance of the ecosystem and promoting the growth of undesirable vegetation. It is often better to manage rangeland through a combination of grazing management, weed control, and reseeding, rather than applying fertilizers.
Question 22 Report
If 200 layers will consume 25kg of feed per day. Calculate the amount of feed consumed by a layer per day.
Answer Details
The amount of feed consumed by a layer per day is 0.125kg/day. This can be calculated by dividing the total amount of feed consumed by 200 layers, which is 25kg, by the number of layers, which is 200. This gives us 25 / 200 = 0.125kg/day. So, each layer consumes an average of 0.125kg of feed per day.

The purpose of game reserves is to conserve the animals and their ecosystems for future generations to enjoy and appreciate.
Question 24 Report
The alternate heating and cooling of rocks result in
Answer Details
The alternate heating and cooling of rocks can result in a process called thermal stress. When rocks are subjected to changes in temperature, the different layers of the rock expand and contract at different rates. This can cause stress on the rock and over time, it can lead to cracking and breaking, a process known as fragmentation. This can happen as a result of volcanic activity, tectonic activity, or weathering and erosion. The rocks can also undergo cycles of heating and cooling and this can result in the formation of fractures and joints. In some cases, the heat can be so intense that it causes the rocks to melt, resulting in the formation of magma and new igneous rocks.
Question 25 Report
Which of the following sources of farm power is most versatile in West Africa?

The most versatile source of farm power in West Africa is likely to be animal power, specifically using oxen or cattle to plow fields and perform other tasks. In many rural areas of West Africa, access to electricity and other modern sources of energy is limited, making it difficult to use more technologically advanced methods like biogas, wind, or water power. However, animals such as oxen or cattle are readily available and can be trained to perform a wide range of tasks on the farm. In addition, animal power is flexible and can be used for a variety of purposes, including plowing, transportation, and even as a source of fertilizer. This versatility makes animal power a valuable asset for farmers in West Africa.
Question 26 Report
The horizon of a soil profile which encourages the greatest level of microbial activity is
Answer Details
The horizon of a soil profile that encourages the greatest level of microbial activity is the A horizon. Soil horizons are defined layers in a soil profile, each with its own distinct physical and chemical properties. The A horizon, also known as the topsoil, is the topmost layer of the soil profile and is typically rich in organic matter, nutrients, and water. This layer is also where the majority of soil microbes, such as bacteria, fungi, and other microorganisms, are found. The B horizon, also known as the subsoil, is below the A horizon and is typically more compact and less porous than the A horizon. It contains relatively low levels of organic matter and is not as conducive to microbial activity as the A horizon. The C horizon is the layer of soil material that is below the B horizon and is composed of partially weathered rock fragments and mineral particles. This layer typically has low levels of organic matter and is not as conducive to microbial activity as the A horizon. The D horizon is not present in all soils and is typically composed of consolidated bedrock. This layer is not conducive to microbial activity as it is typically inhospitable to life due to its lack of water and organic matter. So, the answer to the question is the A horizon.
Question 28 Report
The hormone responsible for milk let down in female farm animals is
Answer Details
The hormone responsible for milk let down in female farm animals is oxytocin. Oxytocin is produced by the pituitary gland and is released into the bloodstream when the animal is ready to nurse its young or be milked. When oxytocin is released, it stimulates the contraction of the muscles in the mammary glands, causing the milk to flow from the teat. This hormone plays a crucial role in the lactation process and is essential for providing nourishment to the young in many species of mammals, including cows, goats, and sheep. The release of oxytocin can also be triggered by the stimulation of the teats, such as when a calf or kid suckles or when a milker applies a milking machine to the teat, making it a key player in the dairy industry.
Question 30 Report
Which of the following is the correct order for land preparation?
Answer Details
The correct order for land preparation is: land clearing → ploughing → harrowing → ridging. Land clearing involves removing trees, bushes, and other vegetation from the land to make it ready for farming. Ploughing is the process of breaking up the soil using a plough to make it easier to plant seeds and improve water and air penetration. Harrowing is the process of breaking up any clumps of soil formed after ploughing and smoothing out the soil surface. Ridging involves creating raised beds or mounds of soil in the field to improve drainage and to provide a place for planting crops. By following this order, the soil is properly prepared for planting and the crops are more likely to grow well and produce a good harvest.

Question 34 Report
If 100 pieces of pests is attacking an hectare of cocoa farm and 25% suddenly died while 40% of the remnant is sent for medical examination. What is the number of pest remaining?
Answer Details
Let's first find out how many pests there were before 25% died. If 100 pests are attacking an hectare of cocoa farm, and 25% of them suddenly died, then 100 * 25/100 = 25 pests died. So, before 25% of the pests died, there were 100 pests. And after 25% died, there were 100 - 25 = 75 pests left. Next, let's find out how many pests were sent for medical examination. If 40% of the 75 pests that were left were sent for medical examination, then 75 * 40/100 = 30 pests were sent for medical examination. So, the number of pests remaining after some were sent for medical examination is 75 - 30 = 45 pests. Therefore, the answer is 45 pests.
Question 35 Report
Which of the following surveying equipment is used for measuring angles during farm surveying?
Answer Details
The surveying equipment used for measuring angles during farm surveying is a Theodolite. A Theodolite is a precision instrument used to measure both horizontal and vertical angles. It consists of a rotating tripod mounted telescope that can be swiveled both vertically and horizontally. The Theodolite is used to determine angles between points on the land, which is important in farm surveying to calculate the slope of the land, the direction of water flow, and other important aspects of land management. The Theodolite makes precise measurements by using a system of crosshairs and a protractor-like scale. This information is used to create maps and plans for the farm, which helps farmers to make informed decisions about planting crops, managing water resources, and other important tasks.
