Effect of Inorganic and Organic Fertilizers on the Yield and Quality of Sugarcane

Abstract

The field experiment was conducted to evaluate the effect of inorganic and organic fertilizers on the yield and quality of sugarcane at the research block of the National Sugarcane Research Program, Jeetpur, Bara, Nepal during 2020-2020. The experiment was laid out in a randomized complete block design with three replications. A total of nine treatments (50% RDF, 100% RDF, FYM (15 t/ha) + 50 % RDF, FYM (15 t/ha) +100% RDF, FYM (7.5 t/ha) + 50% RDF + BF, FYM (7.5 t/ha) + 100% RDF + BF, 50% RDF + BF, 100% RDF +BF and no fertilizer/manure) were included in the experiment. The variety was CO 7250. The results showed that integrated application of inorganic or organic nutrient sources along with biofertilizers recorded higher cane yield and the number of millable canes. The results of the study suggest that integrated use of organic manure, chemical fertilizer, and biofertilizer [FYM @ 7.5 t/ha+100% RDF + biofertilizer (PSB and Azotobacter @10 kg/ha) 50% RDF + biofertilizer (PSB and Azotobacter @10 kg/ha)] is an effective and sustainable method for producing sugarcane. However, the study should be conducted over locations so that the best integrated nutrient management could be recommended for the wider area.
