Question 1 Report
Fertile soil is one which
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 2 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 3 Report
Ginning is a method of processing
Answer Details
Ginning is a method of processing cotton. Ginning is the process of separating the cotton fibers from the seeds in cotton crops. The cotton fibers are used to make textiles, while the cotton seeds are used for oil production. Ginning is done by passing the cotton through a machine called a cotton gin, which uses a combination of mechanical and manual processes to separate the fibers from the seeds. Cocoa, oil palm, and palm kernel oil are not processed by ginning. Cocoa is a crop that is used to make chocolate, while oil palm is a type of palm tree that is grown for its oil-rich fruit. Palm kernel oil is derived from the seeds of the oil palm tree and is used in a variety of food and industrial products. So, the answer to the question is cotton.

These forms of financial support are intended to help farmers purchase necessary equipment, improve their farming practices, and increase their food production. However, financial assistance in the form of tax is not typically offered to farmers. Tax is a financial obligation that must be paid by individuals and businesses, including farmers, to the government. Tax is not considered a form of financial assistance as it is not intended to provide financial support to the taxpayer. Instead, tax is used to fund various government services and programs.
Question 9 Report
The effects of practicing crop rotation include the following except
Answer Details
The option that does not describe the effect of practicing crop rotation is "adding humus to the soil." Crop rotation involves planting different crops in a specific sequence in a certain area over time. The purpose of this is to maintain and improve soil fertility, control soil erosion, and prevent the build-up of pests and diseases. By rotating crops, the soil is given a chance to rest and recover nutrients that were taken away by previous crops, leading to healthier soil and better crop growth. On the other hand, adding humus to the soil involves adding organic matter such as compost, leaves, or manure to the soil. This helps to improve soil structure, water retention, and nutrient availability. While adding humus to the soil can complement the effects of crop rotation, it is not a direct result of practicing crop rotation.
Question 11 Report
Which of the following constitutes subsidy in agricultural enterprise?
Answer Details
A subsidy in agricultural enterprise is a financial benefit provided by the government to support the agricultural sector. It can take many forms, but one example is the supply of fertilizers to farmers at a reduced price. In this scenario, the government reduces the cost of fertilizers for farmers by providing subsidies, making it more affordable for them to purchase the necessary inputs to grow their crops. This helps to improve the overall productivity and competitiveness of the agricultural sector, and can have a positive impact on the lives of farmers and the local economy. The other options listed (borrowing of money from a thrift society, provision of money to farmers through commercial banks, and provision of services through cooperative societies) are not considered subsidies in the strictest sense. However, they may still provide valuable support to farmers and the agricultural sector in other ways.
Question 13 Report
Food shortage can be minimized by
Answer Details

Question 18 Report
Which of the following agricultural extensions aims at reaching a large number of farmers at the same time?
Answer Details
The agricultural extension method that aims at reaching a large number of farmers at the same time is the mass method. The mass method involves using mass media, such as radio and television, to reach a large audience with information about agriculture. This method allows extension workers to reach many farmers at once, even in remote areas, and to provide them with important information about new techniques, best practices, and other aspects of agriculture. The group method involves working with small groups of farmers to provide them with information and support. This method can be effective for building relationships and addressing specific local issues, but it may not reach as many farmers as the mass method. The individual method involves working one-on-one with farmers to provide them with information and support. This method can be very effective for addressing specific needs, but it may not reach as many farmers as the mass or group methods. The contact method involves making personal visits to farmers to provide them with information and support. This method can be effective for building relationships and addressing specific needs, but it may not reach as many farmers as the mass, group, or individual methods.
Question 19 Report
Ginger is propagated by
Answer Details
Ginger is propagated by rhizomes, which are underground stems that grow horizontally and produce roots and shoots. Essentially, you can plant a piece of a ginger rhizome, and it will grow into a new plant. This is a common way to propagate ginger because it is easy and efficient, and it allows you to quickly produce many new plants from one parent plant. In simple terms, you can think of rhizomes as "cuttings" that you can take from an existing ginger plant and plant elsewhere to grow a new plant.
Question 20 Report
Rocks formed by the cooling and solidification of molten rocks called magma ejected from beneath the earth's crust is
Answer Details
The correct answer is: Igneous rock. Igneous rock is a type of rock that forms from the solidification of magma or lava. Magma is molten rock that is found underneath the Earth's crust. When the magma rises to the surface and cools down, it solidifies into a rock that we call igneous rock. Examples of igneous rocks include granite, basalt, and pumice. Metamorphic rock, on the other hand, is a type of rock that forms from the alteration of existing rocks due to heat, pressure, and/or chemical processes. These rocks are transformed from one type of rock into another. Sedimentary rock is a type of rock that forms from the accumulation and compression of sediment, such as sand, mud, and other organic materials. These rocks are often found in layers and can contain fossils. Caleima rock is not a recognized type of rock.
Question 21 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 22 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 30 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.

In the case of root-knot disease of tomato, the nematodes feed on the roots of the plant, causing knots or galls to form. This can result in reduced growth, reduced yields, and in severe cases, death of the plant. The nematodes can survive in the soil for long periods of time and they can infect a wide range of plants, including tomatoes, peppers, melons, and many others. To control root-knot disease, it is important to practice good crop rotation, avoid planting susceptible crops in infested soil, and use nematicides if necessary.
Question 39 Report
Rain water is made available to crops through
Answer Details
Rain water is made available to crops through root absorption. This is the process where plant roots take in water from the soil. The plant roots absorb the rain water and use it to grow and support the plant. The water is transported from the roots to the leaves, flowers and fruits through a system of tubes in the plant called the xylem. This water is then used by the plant to carry out important functions such as photosynthesis and transpiration. Transpiration is the process where water is released from the leaves into the atmosphere through tiny pores. This helps to regulate the temperature of the plant and also returns some of the water back to the atmosphere, where it can be reused as rain.
