What is the main use of a gunter's chain?
Detalles de la respuesta
A Gunter's chain is mainly used for taking measurements of distances. It is a survey tool consisting of a chain of 100 links, each link measuring 7.92 inches in length. This makes the total length of the chain 66 feet, or 22 yards. Surveyors use the Gunter's chain to measure distances and to calculate the size of an area by counting the number of chains that fit into the space. By using this tool, surveyors can accurately determine the dimensions of land, buildings, and other structures.

Which of the following factors usually affects the colour of egg yolk?
Detalles de la respuesta
The main factor that affects the color of egg yolk is the type of feed that the laying hen eats. The yolk gets its color from pigments found in the foods that the hen consumes, such as yellow and orange pigments from corn, marigold petals, and other yellow and orange plants. If a hen eats a diet rich in yellow and orange pigments, the yolk will be a deeper yellow color. On the other hand, if a hen eats a diet that lacks these pigments, the yolk will be lighter in color. The other factors, such as the age of the hen and the type of housing, may also have some impact, but to a much lesser extent compared to the type of feed.
Pregunta 5 Informe
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.

Government agricultural policies include the following except
Detalles de la respuesta
The option that is not a typical objective of government agricultural policies is "increasing the number of peasant farmers." While some governments may aim to support small-scale farmers and promote rural development, it is not a direct objective of agricultural policies to simply increase the number of farmers. The other options listed, such as increasing food production, improving efficiency in export crop production, and supplying raw materials for local industries, are more commonly aimed for in agricultural policies as these goals directly impact food security, economic growth, and industrial development.

In subsistence agriculture,
Detalles de la respuesta
Subsistence agriculture is a type of farming where the primary goal is to produce enough food to feed the farmer's family and sometimes a small community. The focus is on meeting the basic needs of the farmers rather than making a profit. In subsistence agriculture, yields are often not as high as in commercial agriculture because the farmers use simple tools and techniques and may not have access to modern inputs like fertilizers and pesticides. The surplus produced is small because the primary aim is to feed the family, so only a small amount is left over for sale or trade. Savings are not a priority in subsistence agriculture, as the focus is on producing enough food to meet the family's needs. The farm sizes are usually small, as the farmer only needs to cultivate enough land to feed their family. Overall, subsistence agriculture is a way of life for many farmers in developing countries, and it provides a basic level of food security for the farmers and their families.

Which of the following is not component of soil?
Detalles de la respuesta
Texture is not a component of soil. Texture refers to the relative proportions of different sized soil particles such as sand, silt, and clay that make up the soil. These particles affect the physical properties of the soil, such as its structure, porosity, and water-holding capacity. The other three options, air, water, and organic matter, are all actual components of soil, as they are all present within the soil and play important roles in the soil's health and fertility.
Pregunta 9 Informe
Which of the following is not the role of government in agricultural production?
Detalles de la respuesta
The role of government in agricultural production that is not typically included is the provision of labor. Governments typically play a role in supporting the agriculture sector by providing loans and credits, building storage facilities, and establishing efficient marketing outlets. However, the direct provision of labor is not usually considered a role of government in agriculture. Instead, it is usually the responsibility of individual farmers or agricultural businesses to hire and manage their own labor force.
Pregunta 10 Informe
Crop rotation has the following effects on the soil except
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.

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.

Agricultural uses of land include
Detalles de la respuesta
Agricultural uses of land include growing crops, raising livestock, and forestry. Crops can be grown for food, feed, fiber, or fuel, and the type of crops grown depends on the climate, soil, and local market demand. Livestock can include cattle, pigs, chickens, and other animals that are raised for food, dairy products, or as draft animals. Forestry involves the cultivation and management of forested land for timber and other forest products. Silviculture, or the cultivation of forested land, is a specific type of forestry. Mining involves the extraction of minerals and other resources from the earth and is not typically considered an agricultural use of land. Housing and transportation are not typically considered agricultural uses of land, as they involve the construction of buildings and infrastructure for human habitation and mobility, respectively.

Under normal circumstances, the concept of consumer sovereignty in agriculture implies that
Detalles de la respuesta
Consumer sovereignty in agriculture refers to the idea that the consumer, not the farmer, determines what should be produced in the agricultural sector. This means that farmers produce what consumers want to buy, rather than what they think is best to grow. Essentially, the demand of the consumers drives the supply of agricultural products. For example, if consumers demand organic produce, farmers will shift their production towards organic crops to meet that demand. In this way, consumer sovereignty ensures that the needs and preferences of the consumers are being met. However, it's important to note that the concept of consumer sovereignty can sometimes be limited by various factors such as government policies, production costs, and environmental constraints.

Detalles de la respuesta
Birds temporarily store their food in the crop. The crop is a small pouch-like organ located near the bird's throat. It can stretch and expand to store food before it moves down to the rest of the digestive system. The food is softened and moistened in the crop, and then gradually passed on to the gizzard, which is a muscular part of the stomach where food is ground and broken down further. The gizzard is followed by the proventriculus and duodenum, where the food is further processed and digested.

Pregunta 25 Informe
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.

Detalles de la respuesta
The most efficient irrigation method for large scale farms is the use of overhead irrigation facilities, also known as center pivot or lateral move systems. This method involves a large tower in the center of the field that rotates, with long pipes extending from the tower and sprinklers attached to the pipes. The sprinklers water the crops evenly, without the water being absorbed too quickly into the ground, ensuring that the crops receive enough water to grow properly. This method is efficient because it can cover a large area, uses less water compared to flood irrigation and is easy to manage.

Detalles de la respuesta
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.

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.
