Abstract

                                The place of manures and fertilisers in a system of integrated crop production needs hardly to be emphasised. In Madras, cotton is grown over 16 million acros annually, and as a cash crop plays a vital role in the economy of the farmer. The need for augmenting cotton yields is obvious, especially due to short production of raw cotton needed for the country and the high cash return assured to growers due to attractive price levels.
