When individual crop with desired characteristic mostly favoured by the environment are chosen for breeding this type of breeding is referred to as
Bayanin Amsa
The type of breeding described in the question is called "selection". Selection involves choosing individual plants with desired traits from a population of plants and using them to produce the next generation. This can be done over many generations to develop a population of plants with consistently desirable traits. In this type of breeding, plants that already have desirable traits that are well-adapted to their environment are chosen for breeding to develop a new population of plants with those desirable traits. This method is commonly used in agriculture to develop new crop varieties that have improved yield, disease resistance, or other desirable traits.

The water-snail is important in the life-cycle of
Bayanin Amsa
The water-snail is important in the life-cycle of a liver fluke. The liver fluke is a parasitic flatworm that infects the liver of various animals, including humans. The adult fluke releases its eggs in the bile ducts of the host, which are then excreted through feces. The eggs hatch in water, and the larvae infect snails. Inside the snail, the larvae multiply and undergo a series of developmental stages, eventually emerging as infectious forms that can infect other animals, including humans, through the consumption of contaminated water or vegetation. Therefore, the water-snail plays a crucial role in the life-cycle of the liver fluke by serving as an intermediate host for the parasite.

Control of water level in a fish pond with minimal loss of fish can be achieved with the aid of
Bayanin Amsa
The best option for controlling water level in a fish pond with minimal loss of fish is a "monk with panel, screens and outlet channel". A monk is a structure that controls the flow of water in a pond. With a monk, water can be drained from the pond while the fish are kept safe in a compartment created by screens and panels. This method is effective in preventing fish from being carried away with the water during drainage. Wooden panels alone or wooden panels with screens may not be as effective in controlling the flow of water as the monk method. Similarly, using only screens or a monk without an outlet channel may not provide the necessary drainage required for the pond.

Bayanin Amsa
In underground drainage, water seeps into the tiles to reach an outlet where water is disposed. Underground drainage is a method of removing excess water from the soil through a system of buried tiles, which are porous and allow water to seep through. These tiles are laid out in a network of drains or channels, leading to an outlet or a collection point where water can be disposed of. The water is directed away from the crop roots and towards a designated disposal area, preventing waterlogging and soil saturation that can damage crops.
Tambaya 30 Rahoto
Which of the following will be responsible for the poor yield of fertile soil in a high rainfall area?
Bayanin Amsa
In a high rainfall area, the poor yield of fertile soil may be due to leaching of soil nutrients. This occurs when there is excessive rainfall, which causes the nutrients in the soil to be washed away, leaving the soil nutrient-deficient. When this happens, the plants growing on the soil will not have the necessary nutrients for growth and development, which can lead to poor yield. The other options, such as low pH, lack of soil microbes, high alkalinity, and erosion, can also affect agricultural productivity, but they may not be specifically related to high rainfall areas.

Which of the following factors has the greatest influence on crop production?
Tambaya 33 Rahoto
Which of the following is not a reason for preferring rotational grazing to continuous grazing?
Bayanin Amsa
The reason for not preferring rotational grazing to continuous grazing is "avoiding excessive amount of organic manuring." Rotational grazing involves the movement of livestock from one paddock to another in a planned sequence. This helps to avoid overgrazing in a particular area and allows time for pasture regrowth, which can result in more uniform quality of herbage, persistence of desired species, breaking the life-cycle of some pests, and avoiding build-up of livestock pests. However, rotational grazing can also lead to excessive accumulation of animal waste in a particular area, which can result in soil compaction, nutrient imbalance, and potential environmental issues. Therefore, it is important to manage rotational grazing properly to avoid excessive accumulation of organic matter in one area.

Tambaya 36 Rahoto
Which of the following will retain the greatest amount of water?
Bayanin Amsa
Clay will retain the greatest amount of water compared to the other options. This is because clay has smaller particles than sand or silt, which allows it to hold more water due to the greater surface area available for water molecules to bond to. Clay soils can retain water for longer periods of time, which can be beneficial for plant growth during dry periods. In contrast, sandy soils have larger particles with fewer surfaces available for water bonding, causing water to drain away more quickly. Loam soils are a mixture of sand, silt, and clay, and can have varying water retention capacities depending on the ratio of the soil components.

Bayanin Amsa
Ground maize, also known as cornmeal, is a common ingredient in livestock feed. Its main function is to provide energy to the animals. Maize contains high levels of carbohydrates, which are easily digestible and can be converted into energy by the animal's body. This energy is necessary for the animal to carry out its normal activities, including growth, reproduction, and movement. While maize does contain some protein, it is not a significant source of building blocks for the animal's body. Other feed ingredients, such as soybean meal or alfalfa, are typically added to provide the necessary proteins for body building. Ground maize also helps to add bulk to the feed, making it more filling and providing the animal with a sense of satiety.

Bayanin Amsa
A fertile soil is important for the selection of a site for a fish pond because it stimulates the growth of lower plants, which are sources of food to fish. When the soil is fertile, the plants growing in and around the pond will have access to necessary nutrients that they need to thrive. The plants will, in turn, produce more organic matter, which will support the growth of plankton and other microorganisms in the water. This increase in food will provide a suitable habitat for fish to grow, feed, and reproduce. Therefore, a fertile soil is crucial in promoting a healthy and productive ecosystem in a fish pond.

With the aid of a labelled diagram, describe briefly the nitrogen cycle.
The nitrogen cycle is a natural process that involves the transformation of nitrogen from one form to another. Nitrogen is a crucial element required for the growth and development of plants and other living organisms. However, nitrogen in its gaseous form (N2) cannot be used by plants directly. Therefore, it has to be converted into other forms such as ammonia, nitrate, and nitrite, which plants can absorb and use.
The nitrogen cycle can be divided into several steps:

The nitrogen cycle is a natural process that involves the transformation of nitrogen from one form to another. Nitrogen is a crucial element required for the growth and development of plants and other living organisms. However, nitrogen in its gaseous form (N2) cannot be used by plants directly. Therefore, it has to be converted into other forms such as ammonia, nitrate, and nitrite, which plants can absorb and use.
The nitrogen cycle can be divided into several steps:
Here is a labelled diagram of the nitrogen cycle:

(a) Discuss briefly the rosette disease of groundnut under the following headings: (i) causal organism: (ii) symptoms (iii) method of transmission; (iv) damage done (v) preventive and control measures.
(b) Assuming the spacing of a g vegetable crop per stand is 30 cm x 30 cm, calculate the plant population expected in a portion of land measuring 60 m x 30 m
(a) Rosette disease:
(i) Causal organism: Rosette disease is caused by a virus called Groundnut Rosette Virus (GRV). It is transmitted from plant to plant by an insect vector known as the groundnut aphid (Aphis craccivora).
(ii) Symptoms: Infected plants show symptoms such as excessive branching, development of small leaves, and the formation of rosettes (bunches of small leaves at the top of the plant). The pods are also small and poorly developed.
(iii) Method of transmission: The groundnut aphid is the vector that transmits the virus from plant to plant. It feeds on infected plants and carries the virus to healthy plants.
(iv) Damage done: The virus causes significant yield losses in groundnut production. Infected plants have reduced growth, low yields, and poor-quality pods.
(v) Preventive and control measures: The following measures can be taken to prevent and control the spread of Rosette disease: planting of disease-resistant varieties, crop rotation, intercropping with non-host crops, destruction of infected plants, and use of insecticides to control the groundnut aphid vector.
(b) Calculation of plant population:
To calculate the plant population expected in a portion of land measuring 60 m x 30 m with a spacing of 30 cm x 30 cm, we need to convert the dimensions of the land into centimeters. 60 m x 30 m = 6000 cm x 3000 cm.
Next, we calculate the area of the land in square centimeters: 6000 cm x 3000 cm = 18,000,000 square centimeters.
To calculate the number of plants per square meter, we need to divide the area of each plant (30 cm x 30 cm = 900 square centimeters) by the area of one square meter (100 cm x 100 cm = 10,000 square centimeters).
So, the number of plants per square meter is: 10,000 square centimeters / 900 square centimeters = 11.11 plants per square meter.
Finally, to calculate the plant population expected in the portion of land, we multiply the number of plants per square meter by the total area of the land: 11.11 plants per square meter x 18,000 square meters = 199,980 plants.
Therefore, we can expect a plant population of approximately 199,980 in a portion of land measuring 60 m x 30 m with a spacing of 30 cm x 30 cm.
