Abstract

                                A crop of 30 tons of sugarcane per acre removes 80 lbs. of nitrogen, 50 lbs. of phosphoric acid and 180 lbs. of potash from the soil. An examina- tion of the results of field experiments for 25 years at all the experiment stations in the Presidency, chiefly at Samalkot, Anakapalle and Palur, reveals that the problem of nitrogen nutrition of the sugarcane is of greater importance than that of either phosphoric acid or potash. In the manurial programme of the Experiment stations, the application of oil cakes is the chief item and the soundness of the scheme is reflected in its wide adoption in the sugarcane tracts.
