Which of the following processes is not used in rice processing

Bayanin Amsa

The process that is not used in rice processing is fermentation. Threshing is the process of separating the grain from the straw, while winnowing is the process of separating the chaff from the grain. Perboiling involves partially boiling the rice in the husk, which results in increased nutritional value and easier removal of the husk. Fermentation is a process used in the production of certain types of alcoholic beverages and some food products, but it is not a typical step in rice processing.

Some seeds are raised in the nursery because

Bayanin Amsa

Seeds are raised in the nursery for several reasons, including: - To protect them from harsh environmental conditions, such as extreme temperatures or heavy rain, which could damage or kill the seeds. - To provide them with a controlled environment with optimal growing conditions, such as the right amount of water, nutrients, and light. - To monitor and manage pests and diseases that could harm the seeds. - To allow for easier transplanting and handling of the seedlings once they are ready to be moved to their final growing location.

The following animals are polygastric animals except

Bayanin Amsa

The pig has a digestive system which is classified as monogastric, or nonruminant. Humans also have this type of digestive system. They have one stomach (mono = one, gastric = stomach). The monogastric differs from that of a polygastric, or ruminant, digestive system found in cattle and sheep.

Bayanin Amsa

To abandon the development of rural area.

The removal of excess seedlings from a seedbed after the viable seeds have germinated is

Bayanin Amsa

The process of removing excess seedlings from a seedbed after the viable seeds have germinated is called "thinning".

Agricultural extension serves as ____ between research institute and farmers

Bayanin Amsa

A bridge.

______ introduce new ideas of farming seen in other places to their dwelling.

Bayanin Amsa

Essentially Innovators.  Early adopters too have a minor role to play in this case.

The followings are functions of a sprayer except

Bayanin Amsa

Which of the following is not a pre-planting operations?

Bayanin Amsa

Thinning.

________ is a disease condition which emanates from inadequate nutrition.

Bayanin Amsa

Nutritional deficiency is a disease condition which emanates from inadequate nutrition.

Which of the following classes of nutrient is used only for energy production in farm animals?

Bayanin Amsa

The nutrient class that is used only for energy production in farm animals is Carbohydrates. While all nutrient classes can be sources of energy for animals, carbohydrates are particularly important for providing energy quickly and efficiently. Proteins and minerals are primarily used for building and repairing tissues and structures in the body, while fat and oil serve a variety of functions including energy storage, insulation, and as building blocks for certain hormones.

Bayanin Amsa

Nursery is a special place prepared for raising seedlings which are later taken to the field for planting.

____________ is said to occur when a ration does not provide all the food nutrients in adequate quantities needed by animal.

Bayanin Amsa

Malnutrition is said to occur when a ration does not provide all the food nutrients in adequate quantities needed by an animal.

________ are less quick to accepting innovations which might be largely due to some of the aforementioned factors

Bayanin Amsa

Late adopters.

The B-Horizon of soil profile is also called the

Bayanin Amsa

The B-horizon of soil profile is also called the sub-soil.

The following conditions are necessary for germination except

Bayanin Amsa

The condition that is not necessary for germination is "zero temperature." All seeds require an optimum temperature range for successful germination, which varies among different plant species. While some seeds may require a specific temperature, such as stratification or scarification to overcome dormancy, no seeds can germinate at zero temperature. Therefore, the correct statement is: The following conditions are necessary for germination except zero temperature: - adequate moisture - viable seed - optimum temperature

Bayanin Amsa

Diffusion.

Which of the following is not a type of harvester?

Bayanin Amsa

Plough.

Primary tillage is also known as

Bayanin Amsa

Primary tillage is also known as "ploughing."

The following problems are usually associated with subsistence agriculture except

Bayanin Amsa

The problem that is usually not associated with subsistence agriculture is "it requires a large area of land." Subsistence agriculture is typically practiced on small plots of land and involves growing crops and raising livestock for the sole purpose of feeding one's family, without generating any surplus for sale. The other three problems mentioned (unreliable family labour supply, use of simple tools, and lack of surplus for sale) are all commonly associated with subsistence agriculture.

Which of the following is not an organic manure?

Bayanin Amsa

Fertilizer.

One of the followings is not a basic consideration in planting operations

Bayanin Amsa

Planting weed is not a basic consideration in planting operations. The other options listed are all important factors to consider when planting, as they can affect the growth and development of the plants. Planting space determines how far apart to plant the seeds or seedlings, which affects how much space the plants will have to grow and how much light, water, and nutrients they will receive. Planting time is important because different plants have different requirements for temperature and moisture, and planting at the wrong time can result in poor growth or even the death of the plants. Planting depth is important because different seeds require different depths to germinate properly, and planting too shallow or too deep can affect the germination rate and the growth of the plants.

Broadcast Crop Planter is designed

Which of the following is a powerful and expensive multipurpose motor vehicle used for lifting or pulling farm implements?

Bayanin Amsa

A Tractor is a powerful and expensive multipurpose motor vehicle used for lifting or pulling farm implements.

This is the removal of unwanted plants on the farm

Bayanin Amsa

The correct answer is: Weeding. "Weeding" refers to the process of removing unwanted plants from a farm or garden to help the desired plants grow better. "Thinning" usually refers to the removal of excess plants to allow the remaining plants to grow stronger and healthier. "Mulching" refers to the practice of covering the soil with a layer of material (such as leaves, straw, or bark) to retain moisture, suppress weed growth, and improve soil quality. "Supplying" does not relate to the removal of unwanted plants on a farm. It could refer to the act of providing necessary resources, such as water or nutrients, to the desired plants.
