The preparation of soil is the first step in crop production. It involves loosening the soil, removing weeds, and adding manure or fertilizer. Loosening the soil allows the roots of the plants to grow more easily and deeply. Removing weeds prevents them from competing with the crop plants for water, nutrients, and sunlight. Adding manure or fertilizer helps to improve the fertility of the soil and provides the crop plants with the nutrients they need to grow.
b. Sowing
Sowing is the process of planting seeds in the soil. The seeds are placed in the soil at a specific depth and spacing. The depth of planting depends on the type of seed and the soil conditions. The spacing between seeds depends on the crop being planted. For example, corn seeds are planted about 1 inch deep and 4 inches apart, while wheat seeds are planted about 1/2 inch deep and 1 inch apart.
c. Weeding
Weeding is the process of removing weeds from a crop field. Weeds are unwanted plants that compete with crop plants for water, nutrients, and sunlight. Weeds can also harbor pests and diseases. There are several ways to control weeds, including hand weeding, mechanical weeding, and chemical weeding.
d. Threshing
Threshing is the process of separating the grain from the chaff. The chaff is the outer layer of the grain that contains the husk and other non-edible parts. Threshing is usually done by machines, but it can also be done by hand. The grain is separated from the chaff by beating or rubbing the stalks of the crop.
