Effect of biozyme application on growth, yield, quality and economics of sugarcane

A field experiment was conducted during 1997–98 and 1998–99 at the research farm of U.P. Council of Sugarcane Research, Shahjahanpur to test the efficacy of biozyme application on growth, yield, quality and economics of spring planted sugarcane. Experimental results indicated that 30 kg/ha dose of biozyme granules applied as basal at the time of planting proved beneficial and produced significantly higher cane yield (11.30%) and C:B ratio (11.10%) as compared to control treatment (without biozyme granule + recommended doses of N and P). Further, treatments consisting the application of biozyme granules @ 20 kg/ha as basal coupled with each liquid doses of foliar sprayings (300, 400 and 500 ml/ha at 120 DAP) or 500 ml biozyme liquid (without granules) sprayed half at 120 DAP and remaining half at 150 DAP proved more effective and gave higher cane yield (mean) and C:B ratio to the tune of 4.06% and 5.24%, respectively as compared to different doses of biozyme granules applied as basal without spraying. Comparing control treatment, the highest cane yield and C:B ratio were obtained to the tune of 15.84% and 16.99%, respectively due to the treatment consisting 20 kg biozyme granules as soil application + 500 ml spraying of biozyme; half at 120 and rest at 150 DAP.
