Question 1 Report
A crop not requiring more than 750mm annual rainfall is most suitable for cultivation in
Answer Details
A crop not requiring more than 750mm of annual rainfall is most suitable for cultivation in the "Sahel savanna". 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 2 Report
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.
Question 3 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 4 Report
The causative organism of maize rust is?
Answer Details
The causative organism of maize rust is a fungus. Maize rust is a fungal disease that affects maize plants and is caused by the fungus Puccinia polysora. The fungus infects the leaves of the maize plant, causing yellow to brownish-orange rust-like pustules or spots on the leaves. Maize rust can have a significant impact on crop yield and quality, and it is important for farmers to take steps to prevent and control the disease. This can include the use of disease-resistant maize varieties, crop rotation, proper sanitation practices, and timely application of fungicides when necessary. So, the correct answer is fungus.
Question 5 Report
Which of the following is not a sign of heat in animals?
Answer Details
Mucous discharge from the rectum is not a sign of heat in animals. Heat, also known as estrus, refers to the period in the reproductive cycle of female animals when they are fertile and can mate with males to produce offspring. During heat, females exhibit various physical and behavioral changes to signal their readiness to mate. These changes include swelling of the vulva, increased vaginal discharge, mounting behavior, and restlessness. Mucous discharge from the rectum is not a typical sign of heat in animals. It can indicate a digestive issue or infection, and it is not related to reproductive readiness. Therefore, if you observe mucous discharge from the rectum in your animal, it is important to seek veterinary attention to identify the cause of this symptom.
Question 6 Report
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
Question 7 Report
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.
Question 8 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.
Question 9 Report

Question 14 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 15 Report

Question 17 Report
Legumes are different from grasses, because
Answer Details
Legumes are different from grasses because they form a symbiotic relationship with bacteria called rhizobia in the nodules of their roots. This symbiotic relationship allows legumes to fix atmospheric nitrogen into a form that is available to the plant, which in turn makes them an excellent source of nitrogen for other plants, including grasses. Grasses, on the other hand, do not have this ability to fix nitrogen and rely on other sources of nitrogen such as fertilizers or nitrogen from the atmosphere that has been fixed by other means. In addition to their ability to fix nitrogen, legumes are also an important source of protein and other nutrients for both humans and animals. This is due to the fact that they have a higher protein content than most grasses. Therefore, legumes and grasses serve different purposes in agriculture and can be used together in a complementary way to improve soil fertility and provide a balanced source of nutrition for livestock and humans.
Question 18 Report
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.
Question 19 Report
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.
Question 20 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 21 Report
Newcastle disease is viral diseases that affect which animals?
Answer Details
Newcastle disease is a viral disease that primarily affects poultry birds such as chickens, turkeys, ducks, and geese. This disease can cause severe respiratory, nervous and digestive symptoms in infected birds and can lead to high mortality rates in flocks. In severe cases, Newcastle disease can also spread to other birds in the area and cause outbreaks. 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 22 Report

In this way it is distinct in its effect from the plough, which is used for deeper tillage. The farm machinery used to sow seeds and apply fertilizer at the same time is a harrow. Therefore, choice D is correct.
Question 23 Report
In order to eliminate food shortage, farm as should
Answer Details
To eliminate food shortage, farmers should cultivate more varieties of crops. This means growing different types of crops that are suitable for the local climate and soil conditions. By growing a variety of crops, farmers can reduce their dependence on a single crop, which can be vulnerable to pests, diseases, and other environmental factors. Furthermore, farmers can also use crop rotation, a farming technique where different crops are planted in a specific sequence, to improve soil fertility and reduce pests and diseases. This helps to increase crop yields and ensure a more sustainable food supply. While land tenure by inheritance and constructing farm buildings can be helpful for farmers, they may not directly address food shortage. Similarly, shifting from crop to animal production may not be the most effective solution, as it can require more resources and land to produce the same amount of food.

The type of labour available to peasant farmers is family labour because most peasant farmers practise subsistence agriculture. Choice A is correct.
Question 25 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 26 Report
A good silage should be free of
Answer Details
A good silage should be free of moulds. Silage is made by fermenting green fodder in a silo or pit to preserve it as animal feed. Moulds can grow on the silage if the conditions are not right, such as when there is too much moisture or oxygen in the silo. This can lead to a decrease in the quality of the silage, as well as potential health problems for the animals consuming it. Mouldy silage can contain mycotoxins, which are toxic substances produced by certain types of moulds. When consumed by animals, mycotoxins can cause a range of health problems, including reduced milk production, poor weight gain, and even death in severe cases. Therefore, it is important to ensure that silage is made under the right conditions, such as with the correct moisture content and sufficient compaction to exclude oxygen. This will help to prevent the growth of moulds and ensure that the silage is of good quality for animal consumption.

Question 31 Report
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.
Question 32 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.

Newspaper can only be read by the literate farmers and majority of the farmers are ILLITERATE.
Question 36 Report
Which of the following required daily checking in a tractor?
Answer Details
The engine oil in a tractor is something that requires daily checking. Engine oil is a vital component of any engine, including those found in tractors. It helps lubricate the moving parts of the engine, reducing friction and heat buildup that can damage the engine over time. It also helps remove contaminants and debris from the engine, keeping it clean and operating smoothly. Because tractors are often used in dusty, dirty, and challenging environments, the engine oil can become contaminated quickly. Therefore, it is important to check the oil level and quality on a daily basis to ensure that the engine is properly lubricated and functioning at optimal levels. While other components like the spark plug, air cleaner, and battery are also important and should be checked regularly, they do not require daily checking like the engine oil. In summary, the component that requires daily checking in a tractor is the engine oil.
Question 37 Report
If a crop requires 1.5kg phosphorus per hectare, how many kg of manure will be required per hectare if 1kg manure contains 0.32kg of phosphorus
Answer Details
To calculate the amount of manure required per hectare, we need to use the ratio of phosphorus in manure to the amount of phosphorus required per hectare. Given that 1kg of manure contains 0.32kg of phosphorus, we can calculate the amount of manure required to supply 1.5kg of phosphorus per hectare as follows: 1.5 kg phosphorus / 0.32 kg phosphorus per 1 kg manure = 4.69 kg manure per hectare Therefore, the amount of manure required per hectare to supply the required amount of phosphorus is 4.69 kg. So, (4.69kg) is the correct answer.

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.
Question 39 Report
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.
