Frequently Asked Questions - Crop Production and Management

Crop production refers to the cultivation of crops for obtaining food, fibers, and other useful products through agricultural practices.

The steps include preparation of soil, sowing, adding manure and fertilizers, irrigation, protecting crops from weeds, pests, and diseases, and harvesting.

Soil is ploughed, leveled, and tilled to make it suitable for planting seeds. Addition of organic matter improves soil fertility.

Irrigation provides water to crops in times of inadequate rainfall, ensuring their proper growth, development, and yield.

Sources of irrigation include wells, tube wells, canals, rivers, ponds, and tanks that supply water to fields.

Fertilizers provide essential nutrients to plants, improving soil fertility and promoting healthy growth and better yield.

Weeds are controlled through mechanical methods like ploughing and using herbicides that prevent weed growth without harming crops.

Crop rotation prevents soil nutrient depletion, reduces pests and diseases, and maintains soil fertility by varying crops in a sequence.

Farmers use pesticides, insecticides, and fungicides to control pests and diseases that can harm crops and reduce yields.

Proper storage prevents spoilage, maintains quality, and ensures availability of crops throughout the year, even during non-growing seasons.
