Crop Production and Management

Question:

Write a paragraph in your own words on each of the following.

(a) Preparation of soil

(b) Sowing

(c) Weeding

(d) Threshing

Answer:

(a) Preparation of soil: In this process soil is turned and loosens. The loosening and turning of the soil are called ploughing or tilting. This allows the roots to penetrate deep into the soil. The loose soil allows the roots to penetrate deep into the soil. The loosened soil helps in the growth of earthworms and microbes present in the soil. These organisms further turn and loosen the soil and add humus to it. Turning and loosening of soil bring the nutrient-rich soil to the top so that plants can use these nutrients. 

(b) Sowing: The process of scattering seeds in the soil for growing the crop plants is called sowing. The seeds of the crop are sown in soil once it is prepared by ploughing, levelling and manuring. Before sowing, good quality, clean and healthy seeds of high yields are selected. 

(c) Weeding: The undesirable plants which grow along the cultivated crop are called weeds. The growth of weeds is harmful because they consume the nutrients present in the soil, water, light and space which are meant for the crops and reduce the crop yield and quality of food grains. Therefore, it is necessary to remove the weeds from time to time. The removal of weeds is called weeding. 

(d) Threshing: After harvesting the seed grains are beaten so that they get separated from its outer covering (chaff). This process is called threshing. It is done with the machine called combine or thresher.
