Agricultural Science Questions and Answers

Fish farming can be combined with vegetable production and poultry production for mutual benefits. The waste from the fish can be used as fertilizer for the vegetables, and the vegetables can help filter the water for the fish. Similarly, poultry droppings can serve as a source of food for the fish, and the fish waste can be used as a source of protein for the poultry. Therefore, the correct answer is 'I and III only'.

Steaming up ration is a special diet given to pregnant animals, especially cows, in the last few weeks before calving. It is designed to provide the necessary nutrients to the animal and the unborn calf, and to prepare the cow for lactation. Therefore, the correct answer is 'pregnant animals'.

Monocotyledonous crops typically have leaves with parallel venation. This means that the veins in the leaf run parallel to each other, extending from the base to the tip of the leaf without forming a complex network. The parallel arrangement of veins is a key characteristic that sets monocots apart from dicotyledonous plants (dicots), which have net-veined leaves.

A silo is a storage structure that is commonly used for bulk storage of grains, such as rice, wheat, maize, and other agricultural products. It is often installed by governments and agricultural organizations to store large quantities of harvested grains for future use and to ensure food security.

Assisting farmers in locating sources of farm inputs is the most relevant option for an extension agent to back up extension messages. This support ensures that farmers can implement the recommended practices effectively and achieve better agricultural outcomes.

A pest of honeybees is a creature or organism that poses a threat or causes harm to honeybee colonies or individual honeybees. Among the options provided, the grasshopper is considered a pest of honeybees.

In agriculture, demand and supply are interdependent factors. Demand refers to the quantity of agricultural products that consumers are willing and able to purchase at a given price. Supply, on the other hand, refers to the quantity of agricultural products that producers are willing and able to offer for sale at a given price. The relationship between demand and supply is often represented by the concept of market equilibrium.

The primary role of agricultural extension officers is to offer technical advice and assistance to farmers. Agricultural extension officers are professionals who work closely with farmers to provide them with the necessary knowledge, information, and resources to improve their agricultural practices and increase productivity. They act as intermediaries between agricultural research institutions and farmers, translating scientific knowledge into practical guidance for farmers.

Agricultural extension services provide numerous advantages to farmers and the agricultural sector. Through agricultural extension, farmers gain increased access to modern agricultural technologies, such as improved crop varieties, efficient irrigation methods, and mechanized farming equipment. This leads to improved farm productivity and profitability.

The primary purpose of agricultural mechanization is to reduce labor requirements in agriculture. Agricultural mechanization involves the use of machinery, equipment, and technology to automate and streamline various farming operations. By employing mechanized tools such as tractors, harvesters, planters, and irrigation systems, farmers can increase efficiency, save time, and reduce the physical labor needed for tasks like land preparation, planting, harvesting, and irrigation.
