Question 2 Report
Spermatozoa are produced in the
Answer Details
Spermatozoa are produced in the testicles. The testicles are part of the male reproductive system and are responsible for producing and storing sperm. Sperm are the male reproductive cells that are necessary for fertilization, which is the process by which sperm combine with an egg to form an embryo. The testicles are located outside the body in a sac called the scrotum. This location helps to maintain a temperature that is cooler than the body, which is necessary for optimal sperm production. The production of sperm is a continuous process that starts during puberty and continues throughout a man's life.

The act of giving birth in farm animals is called
Answer Details
The act of giving birth in farm animals is called "parturition." Parturition refers to the process of giving birth, from the onset of labor to the delivery of the offspring. It is a natural process that occurs in mammals, including farm animals such as cows, pigs, sheep, and horses. During parturition, the mother's uterus contracts to push the baby out, and the baby is then born.
Question 7 Report
Capital in agriculture includes the following item except
Answer Details
Capital in agriculture refers to the resources and assets used to produce crops and livestock. It includes items such as machinery, buildings, and land. The option that does not belong in this list is "labour". While labour is an important input in agriculture, it is not considered a capital asset. Capital assets are long-term investments that are used to produce goods over time, while labour is a more immediate input that is used to carry out specific tasks. So, labour is considered an operational cost or an expense, rather than a capital asset, in agriculture. To produce crops and livestock, farmers need both capital assets and labour inputs, but labour is not considered a part of the farmer's capital.
Question 8 Report
Which of the following is not a sign of heat in farm animals?
Answer Details
Udder enlargement is not a sign of heat in farm animals. Udder enlargement is a sign of pregnancy or lactation in farm animals and is not related to heat. The other three options, loss of appetite, restlessness, and grunting, are common signs of heat or estrus in farm animals. During estrus, the female animal is receptive to mating and these signs can indicate to farmers that the animal is ready to breed.
Question 10 Report
To which of the following crops does the term 'ginning' apply?
Answer Details
The term "ginning" applies to cotton crops. Ginning is the process of separating the cotton fibers from the seeds and other impurities. The seeds are removed and the fibers are cleaned, making it easier to spin and weave into fabric. Ginning is an important step in the processing of cotton, as it allows for the production of high-quality cotton fiber that is used in the manufacture of various textiles and other products. Kenaf, cocoa, and groundnut are not crops that are associated with ginning. Kenaf is a fiber crop that is used in the production of various products, including paper and textiles. Cocoa is a crop that is used to produce cocoa powder and chocolate. Groundnut is a crop that is grown for its edible seeds, which are used for food and oil.
Question 11 Report
The length of oestrus cycle (in days) in goat is
Answer Details
The length of the oestrus cycle in goats is typically 18 to 21 days. The oestrus cycle is the period in which a female goat is receptive to mating and can become pregnant. During this time, the goat will show signs of heat, such as increased activity, restlessness, and a swollen vulva. The length of the cycle can vary slightly between individual goats, but it is typically between 18 to 21 days.
Question 12 Report

Answer Details
Andropogon gayanus is commonly called "gamba grass." Gamba grass is a species of grass that is native to Africa and is known for its tall, dense growth. It grows well in hot, wet conditions and is commonly used for forage for livestock, as well as for erosion control and as a fuel source. The name "gamba" comes from the Bantu language and refers to the tall stature of the grass.
Question 15 Report
Which of the following will be responsible for the poor yield of fertile soil in a high rainfall area?
Answer Details
The most likely cause of poor yield of fertile soil in a high rainfall area is leaching of soil nutrients. This is because high rainfall can wash away valuable nutrients and minerals from the soil, making it less fertile and less able to support plant growth. The nutrients are carried away by water, especially in areas with high rainfall, and deposited elsewhere, which makes the soil less rich in nutrients over time. This can be prevented by using proper soil conservation techniques like crop rotation, adding organic matter, and using appropriate fertilizer. Low pH value of land can also affect plant growth, as plants have a preferred range of soil pH for optimal growth. If the soil pH is too low, it can make certain nutrients unavailable to plants and result in poor growth. Lack of soil microbes can also impact plant growth, as these microbes play an important role in breaking down organic matter and releasing nutrients for plants to use. High alkalinity of soil can also affect plant growth, as some plants are sensitive to high levels of alkalinity and may struggle to absorb necessary nutrients.
Question 16 Report
Smut disease of cereals is caused by a
Answer Details
Smut disease of cereals is caused by a fungus. A fungus is a type of microorganism that can cause diseases in plants. The fungus infects the cereal plant and causes it to produce abnormal growths, called galls, in place of kernels. These galls eventually burst open and release spores of the fungus that can infect other plants. This can result in significant yield loss and reduced quality of the cereal crop.
Question 17 Report
Management practices in a piggery include the following except
Answer Details
The management practice in a piggery that is not included is weekly vaccination of pigs. Disinfecting pens helps prevent the spread of disease by killing germs and bacteria. Regular cleaning of feed and water troughs ensures that the pigs have access to clean food and water, promoting their health and well-being. Isolating sick animals helps prevent the spread of disease to healthy pigs, and is an important part of disease control in a piggery. However, weekly vaccination of pigs is not a standard practice in a piggery. Pig vaccination schedules vary depending on the specific disease being targeted, the age and health of the pigs, and other factors. Typically, pig vaccination is done on a regular basis, but not necessarily every week. It is important to consult with a veterinarian to develop an appropriate vaccination schedule for your pigs.

Question 19 Report
Leguminous cover crops do not
Answer Details
Leguminous cover crops do not reduce the soil microbial population. In fact, they do the opposite - they aid in increasing the soil microbial population. This is because leguminous cover crops have the ability to fix nitrogen from the air and add it to the soil, providing a source of nutrition for soil microorganisms. Additionally, their roots and leaves also add organic matter to the soil as they decompose, which further supports the growth of soil microorganisms. So, leguminous cover crops are beneficial for soil health and fertility, not detrimental.
Question 20 Report
Investments with long life span in agricultural economics are otherwise known as
Answer Details
The term used to describe investments with a long lifespan in agricultural economics is "capital." Capital refers to the resources, including money, property, and equipment, that are invested into a business or enterprise with the expectation of generating long-term income or profit. In agriculture, capital is often used to purchase land, build structures, buy machinery, or make other investments that will support the production of crops or livestock over a period of many years. This type of investment is different from savings deposits, which are designed to be a low-risk, short-term way of saving money, or from profit, which refers to the money made from a business after all expenses have been taken into account.
Question 21 Report
Animal which chew the cud are
Answer Details
The group of animals that chew the cud are "ruminants." Ruminants are a group of mammals that include animals such as cattle, sheep, goats, buffalo, and deer. These animals have a unique digestive system that allows them to break down tough plant material, such as grasses and leaves, by regurgitating and re-chewing their food (known as cud). This process helps to release more nutrients from the plant material, which can then be absorbed by the animal's digestive system. Amphibians, aves (birds), and reptiles do not chew the cud and have different digestive systems.
Question 22 Report
The quantity of rice that a consumer is willing and able to buy during a given period is simply the consumer's
Answer Details
The quantity of rice that a consumer is willing and able to buy during a given period is the consumer's demand for rice. Demand for rice refers to the amount of rice that a consumer is willing and able to buy at a specific price. When the price of rice goes up, demand for rice may go down, and vice versa. This relationship between price and demand is a key concept in economics and helps to determine the market price for a good or service.
Question 24 Report
The mating of a white fulani bull and an N'dama cow could be termed?
Answer Details
The mating of a white fulani bull and an N'dama cow is called cross breeding. Cross breeding is the mating of two animals from different breeds, or sometimes even different species, with the aim of creating offspring with desirable traits from both parents. In this case, the white fulani bull and N'dama cow are two different breeds, therefore their mating would be considered cross breeding.
Question 25 Report
The process of stopping a young animal from milk and placing it under hand feeding is
Answer Details
The process of stopping a young animal from drinking milk from its mother and feeding it by hand is called weaning. Weaning is the process of gradually introducing solid food and reducing the amount of milk or formula that the young animal receives. This is an important step in the development of the young animal as it helps them transition from a milk-based diet to a more solid and varied diet. The goal of weaning is to promote healthy growth and development, and to prepare the young animal for a self-sufficient life.
Question 26 Report
Crop rotation has the following effects on the soil except
Answer Details
The option that does not describe an effect of crop rotation on the soil is "predisposing soil to leaching". Leaching is the process of soil erosion by water, where water removes nutrients and minerals from the soil. Crop rotation can have the opposite effect on the soil, by improving its structure and maintaining its fertility, which can help to retain nutrients and minerals in the soil. In simple terms, crop rotation helps to keep the soil healthy and productive by alternating different types of crops in a specific order, which helps to prevent the build-up of soil pests, improve the soil structure, and maintain soil fertility.
Question 27 Report
Answer Details
The main purpose of including leguminous crops, such as beans and peas, in pastures is to serve as a source of proteins for livestock. These crops are high in protein and provide an important source of nutrition for animals, helping to keep them healthy and productive. Additionally, leguminous crops help to improve the quality of the soil by fixing nitrogen, which makes it more fertile and better able to support other plants.
Question 28 Report
Improvement of yam through breeding is difficult because
Answer Details
Improving yam through breeding is difficult because yam is a type of plant that reproduces vegetatively, meaning that it does not have a sexual reproductive system. This means that new plants are produced from the stem, roots or leaves rather than from seeds. As a result, breeding is not as straightforward as it is with plants that produce seeds. Additionally, yam varieties can rapidly multiply, making it difficult to control their growth and ensure that only the desired varieties are being propagated. Furthermore, the genes in yam plants do not segregate in a predictable manner, making it difficult to produce plants with specific traits through breeding.
Question 29 Report
Which of the following is not a sign of animal approaching parturition?
Answer Details
The option "drop in milk production" is not a sign of animal approaching parturition. Parturition refers to the process of giving birth in animals, and there are several physical signs that indicate that an animal is approaching this stage. A soft, pliable and swollen vulva, a relaxed cervix, and a full mammary gland are all common signs that an animal is getting ready to give birth. However, a drop in milk production is not a sign of this, as milk production typically increases as an animal approaches parturition.
Question 31 Report
The soil nutrient which is important as a constituent of plant proteins and hormones is
Answer Details
Sulphur is important as a constituent of plant proteins and hormones. Sulphur is a crucial element for plants, playing a role in many of the plant's key processes, such as growth and the creation of proteins and hormones. Proteins are the building blocks of all living things, and hormones control important functions like flowering and fruiting. Without sufficient sulphur, plants can become stunted and their growth and development can be slowed down. Additionally, some crops like brassicas (e.g. broccoli, cauliflower, and cabbage) are particularly sensitive to sulphur deficiency and may show visible signs of yellowing or stunted growth.

Answer Details
The cracks or crevices that are first noticed on rocks during soil formation are caused by temperature changes. As the temperature fluctuates, it causes the rocks to expand and contract. This repeated expansion and contraction leads to the formation of cracks and crevices in the rocks. Over time, these cracks and crevices can become deeper and wider, and eventually, soil can accumulate in them, leading to soil formation.

Answer Details
The primary role of agriculture is to provide food for people and their animals. This includes crops such as fruits, vegetables, grains, and livestock such as cattle, pigs, and chickens. Agriculture is a fundamental part of our food system, as it produces the majority of the food that we consume on a daily basis. Agriculture is also important for providing employment and income for farmers, as well as raw materials for industries such as food processing, textiles, and biofuels. Additionally, agriculture can also contribute to a country's foreign exchange earnings by exporting crops and livestock to other countries. However, despite these other important roles, the primary purpose of agriculture remains to provide a reliable and sustainable source of food for the growing global population.

Which of the following groups of crops requires a nursery?
Answer Details
All of the groups of crops listed can be grown from seedlings in a nursery, but the specific crops grown in a nursery depend on the farmer's goals and resources. A nursery is a place where young plants are grown until they are big enough to be transplanted into the field. This allows farmers to control the growing conditions, such as temperature, moisture, and light, and to protect the young plants from disease and pests. Crop selection for a nursery will often depend on factors such as the climate, soil type, and market demand for the crops. For example, tomato, cotton, and sorghum are often grown in nurseries in regions with hot and dry climates, while crops such as rice, maize, and cocoa are more commonly grown in nurseries in regions with a tropical or subtropical climate. In conclusion, all of the groups of crops listed can be grown in a nursery, but the specific crops grown in a nursery will depend on various factors such as the climate, soil type, and market demand.
Question 39 Report
Cassava is mainly propagated by
Answer Details
Cassava is mainly propagated by cuttings. Cassava is a tropical root crop that is widely grown for its edible starchy roots. To grow cassava, farmers usually take cuttings from mature plants and plant them directly into the ground. These cuttings will then sprout roots and grow into new plants. This method of propagation is relatively simple and efficient, and it ensures that the new plants will have the same characteristics as the parent plant. Other methods of plant propagation, such as layering, budding, and growing from seedlings, can also be used, but cuttings are the most commonly used method for propagating cassava.
