Title : Field experiment on reduced preparatory tillage.

Author : A.L. Sarpotdar,R.S. Sachan,R.G.Menon and H.L.Kulkarni.

Year : 1975

The trial was taken up to find out the possibilities of reducing the cost of preparatory cultivation in sugarcane where maize is taken as a mixed crop. During 1973 the experiment was laid out in the field with lighter soils A country plow was run once at the bottom of the furrow after the harvest of maize, and sugarcane was planted in the furrows. The treatment was compared with the conventional practice of ploughing and harrowing the field, making ridgesk and furrows and then regular planting. It was found that reduced preparatory tillage did not in any way result in the reduction of yield of cane. The ratoon crop of cane was harvested on 30-11-1975 which did not show any reduction in yield. Refer to Table No. 14 for data collected on the yield of cane and number of millable canes at harvest in the two treatments.
