Question 1 Report
The pox disease in livestock are caused by
Answer Details
The pox disease in livestock are caused by "viruses". Pox diseases are a group of viral infections that affect livestock, including cattle, sheep, and goats. These diseases are highly contagious and can spread rapidly through populations of animals, causing skin lesions, respiratory symptoms, and, in severe cases, death. Bacteria, protozoa, and fungi are not the cause of pox diseases in livestock. Bacteria are single-celled microorganisms that can cause a wide range of diseases in livestock, but they are not responsible for pox diseases. Protozoa are single-celled organisms that can also cause diseases in livestock, but they are not the cause of pox diseases. Fungi are multicellular organisms that can cause infections in livestock, but they are not the cause of pox diseases.

In the case of natural incubation with broody hens, for instance, naturally turkeys are good brooders and the broody hen can hatch 10-15 numbers of eggs. 27 days is the incubation period of turkey while 21 days is for chicken.
Question 6 Report
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 7 Report
Which of the following is not a source of minerals in animal nutrition?
Answer Details
Minerals essential for animal life include common salt (sodium chloride), calcium, phosphorus, sulfur, potassium, magnesium, manganese, iron, copper, cobalt, iodine, zinc, molybdenum, and selenium. The last six of these can be toxic to animals if excessive amounts are eaten. Palm oil not a source of minerals in animal nutrition.
Question 8 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 9 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.
Question 10 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 11 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 12 Report
Which of the following is not a part of the reproduction system of a hen?
Answer Details
The ureter is not a part of the reproduction system of a hen. The ureter is a part of the urinary system and is responsible for carrying urine from the kidney to the bladder. The other three options, funnel, isthmus, and ovary, are all parts of the hen's reproductive system. The funnel is a funnel-shaped opening in the female reproductive system that connects the oviduct and the cloaca, the isthmus is a narrow part of the oviduct that connects the funnel to the uterus, and the ovary is a reproductive gland that produces the eggs.
Question 13 Report
The wear and tear of farm structures over time is described as
Answer Details
The wear and tear of farm structures over time is described as depreciation. Depreciation refers to the decrease in value of an asset over time due to age, usage, or obsolescence. Farm structures such as barns, sheds, and fences are subject to wear and tear due to exposure to weather, use, and other factors. As they age, their value decreases, and this decrease is referred to as depreciation. Depreciation is an important concept in accounting and financial management as it affects the value of assets and can impact a farm's financial performance.
Question 14 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 15 Report
Which of the following is not a source of farm power?
Answer Details
Farm operations are done by different sources of power, namely human, animal, oil engine, tractor, power tiller, electricity and renewable energy (biogas, solar and wind). Human beings are the main source of power for operating small tools and implements. Choice D is correct. Plough is not 2 source of farm power.
Question 16 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 17 Report
The most effective method of controlling or preventing viral diseases in plants is by
Answer Details
Prevention, or at least alleviation, of the effects of viruses, involves:
(1) Elimination of sources of virus.
(2) Elimination of the virus from infected plants.
(3) Control of vectors.
(4) Breeding for resistance and the use of cross-protection methods.
Each of these approaches to control will be considered.
Planting resistant varieties of a plant/crop is the most effective method of controlling or preventing viral diseases since, the varieties can resist viral infections.
Question 18 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 19 Report
Fertilizer application in maize should be completed before
Answer Details
Fertilization or fertilizer application is the supplemental application of plant nutrients to crop plants to augment the supply from natural sources. This consists of applying nutrient-containing materials, called fertilizers, generally into the soil in proximity to receptor plants.

Answer Details
Coffee is cultivated in many places in tropical Latin America, Asia and Africa between the Tropic of Cancer and the Tropic of Capricorn. It grows best in places with rich soil, reliable rainfall and altitudes between 3000 and 6000 feet. As a rule, the higher the elevation the coffee is grown the better the quality. The ideal pH of coffee is between 6.5 to 7.5. Therefore, choice D is correct.
Question 23 Report
The non-oil crop among the following is
Answer Details
Cowpea is the non-oil crop among the following. While coconut, beniseed (sesame), and melon are all oil crops that are grown primarily for their oil-rich seeds, cowpea is a legume crop that is grown for its edible seeds, which are rich in protein and other nutrients. Cowpea is commonly consumed as a food crop in many parts of the world, and it is also used as a forage crop for livestock. Unlike coconut, beniseed, and melon, which are all highly valued for their oil content, cowpea is not typically grown for oil production. While it does contain some oil, the oil content of cowpea seeds is relatively low compared to oil crops like coconut and beniseed. Instead, cowpea is grown primarily for its nutritional value and as a source of protein for human and animal consumption. So, of the options given, cowpea is the non-oil crop, as it is not primarily grown for its oil content.
Question 24 Report
One of the symptoms of vitamin deficiency diseases in livestock includes except
Answer Details
General symptoms include stunted growth, delayed maturity, reduced fertility, lowered milk yield, unthrift ness, fragile bones and paralytic syndromes. This can be rectified by feeding of good quality roughages and including mineral mixtures in ration of young and producing stocks and by use of salt bricks. Deficiency in vitamin cannot improve fertility rather it decreases it, leads to loss of appetite, scurvy and rickets.
Question 25 Report
Which one of the following is not a target group of an agricultural Extension agent
Answer Details
The target groups of an agricultural Extension agent are typically individuals or groups who are involved in agriculture or rural development. These can include farmers, rural youth, women's groups, agribusinesses, cooperatives, and others who are engaged in agricultural activities. Of the options given, the one that is not a target group of an agricultural Extension agent is political parties. Political parties are not directly involved in agricultural activities or rural development, and therefore would not typically be a target group for agricultural Extension services. Extension agents are typically tasked with providing education, training, and other forms of support to help farmers and rural communities improve their productivity, sustainability, and economic well-being. They may work with individual farmers or groups, providing information and guidance on topics such as crop and livestock management, pest and disease control, soil fertility, marketing, and other issues that can affect agricultural productivity and profitability. So, the correct answer is political parties.
Question 26 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 27 Report
One major difference between disc plough and disc harrow is
Answer Details
The main difference between a disc plough and a disc harrow is their purpose and how they interact with the soil. A disc plough is used to turn over and break up the soil to create furrows for planting crops, while a disc harrow is used to break up clumps of soil, level the ground, and prepare it for planting by chopping up weeds, roots, and plant residue. The disc part of a plough is notched, which helps it to cut through the soil, while the disc part of a harrow is round, which allows it to smooth out the soil surface.
Question 28 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 29 Report
The demand for agricultural produce is generally
Answer Details
Demand for most farm products is inelastic. People can consume only so much then they are satiated. Even if price drops they will not buy much more. When demand is inelastic a drop in price that spurs more quantity being sold results in lower revenue and profit for the producer.
Choice B is correct. A price inelastic demand would mean that an increase in price would not necessarily lead to a decline in quantity demanded or in case it does proportion of quantity change would be lesser vis a vis the change in price.
Demand tends to be price inelastic for agricultural produce for the following reasons.
1. Price changes don't affect consumption much
2. These produce are mostly necessities
3. Possibility of postponement is not there for most of these produce

Question 31 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.
Question 32 Report

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 33 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 34 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 35 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.

Answer Details
The head of a tapeworm is known as the "scolex". The scolex is the attachment organ of the tapeworm that enables it to attach to the host's intestinal wall. It is a small, flattened structure that contains suckers and hooks, which the tapeworm uses to hold onto the intestine. The rostellum is a structure found on some tapeworms that helps them attach to the host's intestinal wall, but it is not the same as the scolex. Therefore, the correct answer is "scolex" when referring to the head of a tapeworm.
Question 39 Report
In which of the soil layer does most biological activity occur?
Answer Details
Most biological activity in soil occurs in the A-horizon. The A-horizon, also known as the topsoil, is the uppermost layer of soil that is composed of a mixture of mineral particles, organic matter, and living organisms. This layer is particularly rich in organic matter, which provides a food source for microorganisms such as bacteria and fungi that play a vital role in breaking down organic materials and releasing nutrients that plants can use for growth. Additionally, the A-horizon is where plant roots grow and interact with soil organisms, which can influence the health and productivity of both plants and soil. Therefore, the A-horizon is considered the most biologically active layer of soil.
