Improvement in Food Resources
Study Notes
Food is essential for all living organisms to live. We depend on plants and animals for food. The increase in population has created much demand for food. It is important that we should increase food production without degrading our environment and disturbing the balances maintaining it. Hence there is a need for sustainable practices in agriculture and animal husbandry.
Improvement in crop yields
Different crops require different climatic conditions, temperature and photoperiods for their growth and completion of their life cycle. There are some cops which are grown in rainy season, called the kharif crops which extend from June to October. Kharif crops include paddy, soyabean, maize, cotton, green gram and black gram. Rabi crops are grown in the winter season which extends from November to April. Rabi crops include wheat, gram, peas and linseed. The major groups of activities for improving crop yields can be classified as –
- crop variety improvement,
- crop production improvement and
- crop protection management.
