KNOWLEDGE

Crop: - When plants of the same kind are cultivated at one place on a large scale,                  it is called a crop. Cropping patterns :- India is a vast country. The climatic conditions like                                               temperature, humidity and rainfall vary from one region to                                               another. Accordingly, there is a rich variety of crops grown in    ...
