(iii) Provision of Surplus: The progress in agricultural sector provides surplus for increasing the exports of agricultural products.

As the international market is very dynamic and since the price of raw material is constantly fluctuating, the developing countries have now started focusing on the export of manufactured foods to increase the percentage of foreign income.

(ii) It provides carbon which is the major building block of all organic matter
(iii) It helps to purify the atmosphere and also maintain the atmospheric level of carbondioxide
Crop Improvement Is The Breeding Of New Varieties Of Crop That Will Perform Better Than The. Older Ones
