CBSE Class 8 Science Chapter 1 Notes – Crop Production And Management
Till 10,000 B.C.E human beings led a nomadic life, wandering in groups from place to place in search of food and shelter. Later, as the population grew they found methods to cultivate land and produce rice, vegetables, and other food crops. Thus, ‘Agriculture’ emerged. To provide food for a large population — regular production, proper management, and distribution is of vital importance. A series of activities are undertaken by farmers over a period of time for the cultivation of crops. These tasks or activities are known as agricultural practices. The various agricultural practices required for crop production and management are as follows:
- Preparation of soil
- Adding manure and fertilizers
- Protecting from weeds
The climatic conditions in a vast country like India vary from place to place. Despite this diversity, two cropping patterns are followed in India which are known as Kharif and Rabi crops.
|Kharif Crops||Sown during the rainy season (between June to September)||Examples: Soybean, cotton, paddy, groundnut, and maize|
|Rabi Crops||Grown in the winter season (between October to March)||Examples: Wheat, mustard, gram, pea, and linseed|
