Which of the following is not an advantage of drip-irrigation?
Detalles de la respuesta
The disadvantage of drip-irrigation is that its efficiency on water distribution in steep slopes is poor. This means that if the field or the area being irrigated has a steep slope, the water may not be evenly distributed and some areas may receive more or less water compared to others. This can lead to uneven growth or drying of crops in some areas.

Which of the following will be responsible for the poor yield of fertile soil in a high rainfall area?
Detalles de la respuesta
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.

A soil with the PH range of 6.1 to 6.9 can be described as
Detalles de la respuesta
A soil with a pH range of 6.1 to 6.9 is considered slightly acidic. pH is a measure of the acidity or alkalinity of a soil, with a pH of 7 being neutral. Soils with a pH less than 7 are considered acidic, while those with a pH greater than 7 are considered alkaline. A soil with a pH range of 6.1 to 6.9 is slightly acidic because it falls within the range of slightly acidic soils (pH 6.0-7.0). It's important to note that different plants have different pH requirements, so knowing the pH of your soil can help you determine which plants will grow best in your soil.

Improvement of yam through breeding is difficult because
Detalles de la respuesta
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.

The recommended agricultural practice in farm settlement scheme is
Detalles de la respuesta
The recommended agricultural practice in farm settlement schemes is mixed farming. Mixed farming involves the integration of both crop and livestock production on the same farm. This approach provides farmers with a more diverse and stable source of income, as they can earn money from both crops and animals. Additionally, mixed farming can help to improve soil fertility and reduce the risk of crop failure, as the manure produced by livestock can be used as a natural fertilizer for crops. This type of agricultural practice is considered to be more sustainable and resilient than relying solely on one type of production, such as cash crop production or poultry farming.

During which of the following plant propagation methods is the tool represented used?
Detalles de la respuesta
The tool shown is typically used in the plant propagation method of budding. Budding involves taking a bud from one plant and inserting it into a different plant to create a new plant that is a genetic clone of the original plant. This is usually done using a budding knife, which is a sharp, curved blade that is used to make a clean cut in both the parent plant and the rootstock plant. The bud is then inserted into a small incision in the rootstock plant and the wound is covered with tape or a rubber band to hold it in place. After a few weeks, the bud will have rooted into the rootstock and the new plant will be ready to be separated and grown on its own. Seed planting, seedling transplanting, and layering are all other methods of plant propagation, but they do not involve the use of the tool shown in the question.

Detalles de la respuesta
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.

Given a normal situation, what effect will an increase in the supply of cowpea have on its market price? The price
Detalles de la respuesta
An increase in the supply of cowpea will generally lead to a decrease in its market price. This is because, with more cowpea available, there is greater competition among sellers to find buyers for their product, which puts downward pressure on the price. Think of it like this: if there are many people trying to sell the same product, each person will have to lower their price to attract buyers and make a sale. The same is true for cowpea. In a normal market situation, the law of supply and demand states that when the supply of a product increases, the price of the product will decrease, assuming everything else remains constant. This is because the increased supply creates an excess of the product, making it more readily available and easier for consumers to find. With more supply and no change in demand, the price drops to encourage people to buy more.

Detalles de la respuesta
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.

Detalles de la respuesta
The Nigerian government has helped farmers in marketing a particular crop by the establishment of marketing boards. Marketing boards are organizations set up by the government to regulate and control the marketing of specific agricultural products. They help to ensure that farmers receive fair prices for their crops, and also help to stabilize prices in the market. Marketing boards may also provide support to farmers in areas such as transportation, storage, and grading of crops. Rural schools of agriculture provide education and training to farmers, helping them to improve their farming practices and increase productivity. Rural extension offices provide information and advice to farmers on a range of topics, including best practices for growing crops and marketing their products. Markets for the sale of crops are important places where farmers can sell their products, but they do not provide the same level of support and regulation as marketing boards. By establishing marketing boards, the Nigerian government is helping to create a stable and fair marketplace for the sale of specific crops, providing farmers with a more secure and predictable income.
