Very Short Question and Answers - Crop Protection Management

Farmers use quality seeds, adopt irrigation, use fertilizer and use crop protection measures. This is because combining these practices maximizes crop yield and quality by ensuring proper nutrition, moisture, and protection from pests and diseases.

Weeds are unwanted plants in cultivated fields that compete for food, space, and light. They take up nutrients and reduce the growth of crops, leading to lower agricultural yields.

Insects can affect plants by cutting roots, stems, and leaves, sucking cell sap, and boring into the stems and fruits, which can reduce crop health and yield.

Plant diseases are caused by pathogens such as bacteria, fungi, and viruses, which can be present in the soil, water, and air.

Pesticides are chemicals used to control weeds, insects, and diseases in crops. They include herbicides (for weeds), insecticides (for insects), and fungicides (for fungi).

Excessive use of pesticides can be poisonous to various plant and animal species and may lead to environmental pollution.

Mechanical methods for weed control include manual removal, mowing, and tilling the soil to disrupt weed growth.

Preventive methods include proper seed bed preparation, timely sowing of crops, intercropping, and crop rotation.

Summer ploughing is the practice of ploughing fields deeply during summer to destroy weeds and pests before planting the next crop.

Proper storage of grains is important to prevent losses due to biotic factors like pests and abiotic factors such as moisture and inappropriate temperatures.

Storage losses can be caused by biotic factors like insects, rodents, fungi, mites, and bacteria, as well as abiotic factors like inappropriate moisture and temperature.

Preventive measures include cleaning the produce, drying it properly first in sunlight and then in shade, and fumigating with chemicals to kill pests.

Eggs contain approximately 12% fat, 13% protein, 1% minerals, and 74% water. They are also rich in vitamins B2 and D.

Cow's milk contains vitamins B1, B2, B12, D, and E.

Fish contains about 77.20% water and 2.50% fat.

Removing weeds early is essential to ensure that they do not compete with the crop for nutrients, space, and light, leading to a better harvest.

Resistant varieties of crops are bred to withstand specific pests and diseases, thus reducing the need for chemical interventions.

Intercropping involves planting different crops in proximity, which can improve yield, reduce pest and weed competition, and enhance soil health.

Precautions include strict cleaning of grains, ensuring they are completely dry, and using fumigation to eliminate pests.

Various types of animals, including livestock and pets, can be affected by diseases caused by pathogens like bacteria, fungi, and viruses that can also impact crops.
