Question 5 Report
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.
Question 6 Report
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.

Question 17 Report
In poultry nutrition, the minerals that prevent the laying of thin-shelled eggs are
Answer Details
In poultry nutrition, the minerals that prevent the laying of thin-shelled eggs are calcium and phosphorus. Eggshells are primarily composed of calcium carbonate, so it is important that hens receive an adequate supply of calcium in their diet in order to produce eggs with strong shells. Phosphorus is also important for eggshell quality, as it helps to regulate calcium metabolism and aids in the development of the skeletal system. If a hen does not receive enough calcium and phosphorus in her diet, she may lay eggs with thin, weak shells that are more susceptible to cracking or breaking. This can be a serious problem for egg producers, as it can lead to reduced egg quality and lower profits. Therefore, to prevent the laying of thin-shelled eggs, it is important to ensure that hens receive a balanced diet that includes adequate levels of both calcium and phosphorus.

Question 27 Report
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.
Question 28 Report
The part of the ruminant stomach from which digestive juices secreted is the
Answer Details
The part of the ruminant stomach from which digestive juices are secreted is the abomasum. Ruminants, such as cows, sheep, and goats, have a four-compartment stomach that allows them to break down tough plant material through a process of fermentation. The four compartments of the ruminant stomach are the rumen, reticulum, omasum, and abomasum. The rumen and reticulum are the first two compartments and work together to break down food through fermentation and mixing with digestive juices. The omasum is the third compartment and is responsible for absorbing water and some nutrients. The abomasum is the fourth and final compartment and is equivalent to the true stomach in non-ruminant animals. It is where the majority of digestive juices are secreted and where the final stages of protein digestion occur. The abomasum also secretes enzymes that help to break down fats and carbohydrates. In summary, while the rumen and reticulum of the ruminant stomach are responsible for fermentation and mixing of food, it is the abomasum where the majority of digestive juices are secreted and where the final stages of protein digestion occur.

It is important to maintain good biosecurity measures and to seek veterinary advice if any signs of the disease are suspected in a flock.
Question 30 Report
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.
Question 31 Report
The degree of responsiveness of demand to change in the price of goods or produce is referred to as
Answer Details
The degree of responsiveness of demand to a change in the price of goods or produce is referred to as price elasticity of demand. Price elasticity of demand is a measure of how much the quantity of a good or product demanded will change in response to a change in its price. If the quantity demanded changes a lot in response to a change in price, the demand is said to be elastic, and the price elasticity of demand will be high. If the quantity demanded changes only a little in response to a change in price, the demand is said to be inelastic, and the price elasticity of demand will be low. For example, if the price of a gallon of milk were to increase by 50%, and the quantity of milk demanded were to decrease by only 10%, the demand for milk would be said to be inelastic. On the other hand, if the price of a luxury car were to increase by 50% and the quantity demanded were to decrease by 50%, the demand for luxury cars would be said to be elastic. Price elasticity of demand is an important concept in economics, as it helps producers and policymakers understand how consumers will respond to changes in price. It can also help businesses make decisions about pricing strategies, such as whether to lower prices to increase demand or raise prices to increase profits.

Question 33 Report
Rural farmers mostly obtain loans from
Answer Details
Rural farmers can obtain loans from various sources, but the most common ones are government agencies, merchant banks, and money lenders. Government agencies, such as agricultural development banks, offer loans to farmers at subsidized interest rates to encourage agricultural production and improve food security. These loans are often long-term and have flexible repayment terms. Merchant banks, on the other hand, offer loans to farmers based on their creditworthiness and ability to repay. These loans typically have higher interest rates than government loans, but they may offer more flexibility in terms of loan amount and repayment terms. Money lenders are private individuals or organizations that offer loans to farmers, often at very high interest rates. Farmers who are unable to obtain loans from government agencies or merchant banks may turn to money lenders as a last resort. However, borrowing from money lenders can be risky as the high interest rates and fees can make it difficult for farmers to repay the loan, leading to a cycle of debt and financial insecurity. Overall, it is important for farmers to carefully consider their options and choose the source of loans that best suits their needs and financial situation.
Question 34 Report
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.

The Sahel savanna is a region located in West and Central Africa, characterized by hot temperatures and low to moderate levels of rainfall, typically ranging from 500mm to 750mm per year. This makes it well-suited for crops that do not require high levels of moisture and can tolerate arid conditions. Rainforests, on the other hand, receive much higher levels of rainfall, typically over 2000mm per year, making them less suitable for crops that require less moisture. The Sudan and Guinea savannas, which are located further south, receive slightly higher levels of rainfall compared to the Sahel savanna, but not enough to support crops that require a lot of moisture.
Question 38 Report
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.
Question 39 Report
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.
