Title : EFFECT OF MAIZE INTERCROPPING ON QUALITY AND YIELD OF SUGARCANE.

Author : R.S.Patil,VasudevRao,T.D.Krishnamurthy and S.I. Harlapur.

Year : 1988-89

The local practice is to go for intercropping of maize with sugarcane, both being exhavstive crops they compete for nutrients and light. Maize has a rapid growth rate and smothers the sugarcane crop which has show growth rate for the first 3 months of planting. The experiment was taken with a viewk to know the effect of maize intercropping on sugarcane growth, yield and juice quality. Two varieties CoC 671 and Co 740 were grown with and without maize as intercrop. The treatments were replicated 5 times under randamosed design. The data on yield and quality parameters were recorded and are given in Table 10 and 11.

The experimental results showed that the pol percent juice decreased by 3 to 4 units due to maize intercropping in both the varieties CoC 671 and Co 740. This may be attributed to more number of immature canes at harvest due to late tillers emergence at harvest. There was a significant decrease in yield parameter like millable cane length and cane diameter due to intercropping of maize. Intercropping decreased the cane yield by 40 to 50 M.T per hectare. The yield of maize was 28-30 quintals per hectare even with the additional income of Rs.6,000/- per hectare from maize crop, cultivator still bear loss of Rs.6,000/- to Rs.9,000/- per hectare on account of lower cane yield. The loss to the factory is to the extent of nearly 2 per cent on recovery by crushing cane intercropped with maize.
