Question 1 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 2 Report
The process whereby rocks are broken down into small particles through both physical and chemical factors is known as
Answer Details
The process whereby rocks are broken down into small particles through both physical and chemical factors is known as weathering. Weathering is the process by which rocks and minerals are broken down into smaller particles, called sediment, through a combination of physical and chemical processes. Physical weathering can occur when rocks are exposed to factors such as temperature changes, freeze-thaw cycles, or abrasion by wind or water. Chemical weathering can occur when rocks are exposed to substances like acid rain or the natural acids produced by organic matter in soil. Over time, these processes can cause rocks to break down into smaller and smaller particles, eventually forming soil and sediment that can be transported by erosion.

However, "Lack of good food" is not an importance of agriculture but rather a challenge that agriculture seeks to overcome by providing adequate and quality food for all.
Question 4 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 5 Report

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.
Question 6 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.

Question 9 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 10 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 11 Report
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.
Question 12 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 13 Report
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.
Question 14 Report
All but one are related to surface irrigation?
Answer Details
Surface irrigation is where water is applied and distributed over the soil surface by gravity. It is by far the most common form of irrigation throughout the world and has been practiced in many areas virtually unchanged for thousands of years. Mole drainage is a subsurface method of draining clay soils that experience regular waterlogging from irrigation or high rainfall
Question 15 Report
Fertilizers are applied to fishponds to serve as
Answer Details
Fertilizers are applied to fishponds to serve as nutrients for plankton. Plankton are tiny organisms that live in water and are a primary source of food for fish. Fertilizers contain essential nutrients such as nitrogen and phosphorus that are necessary for the growth and reproduction of plankton. As the plankton grow and multiply, they provide a valuable food source for fish in the pond. Additionally, the plankton consume nutrients in the water, which can help purify it by reducing the levels of harmful chemicals and pollutants. Therefore, applying fertilizers to fishponds can help promote the growth of plankton and ultimately support a healthy ecosystem for fish.
Question 16 Report

Therefore, choice D is correct
Question 17 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.
Question 18 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 19 Report
The maturity period of groundnut in month is
Answer Details
The maturity period of groundnut is typically between 4 to 5 months. This means that from the time the groundnut is planted until it is fully grown and ready for harvest, it takes between 4 to 5 months. During this period, the groundnut undergoes several stages of growth, including germination, flowering, and pod development, until it reaches maturity. The length of the maturity period can vary depending on the specific variety of groundnut and the growing conditions, such as climate, soil, and water availability. However, on average, it takes about 4 to 5 months for groundnuts to reach maturity and be ready for harvesting.

Question 21 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 22 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 23 Report
A soil may be called as alkaline when the pH of the soil is more than
Answer Details
A soil may be called as alkaline when the pH of the soil is more than "7.0". The pH of a soil is a measure of its acidity or alkalinity, with a pH of 7.0 being neutral. Soils with a pH greater than 7.0 are considered alkaline, while soils with a pH less than 7.0 are considered acidic. Soils with a pH greater than 7.0 have a higher concentration of basic (alkaline) ions, such as calcium and magnesium, and a lower concentration of acidic ions, such as hydrogen. These soils can be challenging for some plants to grow in, as they can limit the availability of certain essential nutrients, such as iron and manganese. However, some plants, such as alfalfa and sweet clover, are well-adapted to growing in alkaline soils. Soils with a pH less than 7.0, on the other hand, have a higher concentration of acidic ions and a lower concentration of basic ions. These soils can be ideal for growing certain crops, such as blueberries and cranberries, but can also present challenges for other plants, such as lilacs and hydrangeas.
Question 24 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.

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.

Question 30 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.

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 40 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.
