Abstract
The research experiment was conducted during 2018 (plant cane) and 2019 (ratoon cane) at Instructional Farm, Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri (M. S.) to investigate the, effect of various integrated nutrient management practices and planting geometries on growth, yield, quality and economics of sugarcane (Saccharum officinarum) in lateritic soil of Konkan region. The field experiment was laid out in strip plot design with two factors consisted of six planting geometries viz., 75 cm SRP, 90 cm SRP, 60 - 90 cm PRP, 60 - 120 cm PRP, 60 - 150 cm PRP , 75 - 150 cm PRP and five integrated nutrient management treatments, viz., 100% RDF inorganic, 75% RDF N inorganic + 25% N organics, 50% RDF N inorganic + 50% N organics, 25% RDF N inorganic + 75% N organics and 100% N organics. Among the various planting geometries, planting of cane at 60-120 cm paired row recorded significantly higher number of millable cane, tillering ratio, dry matter accumulation, number of tillers, height of plant, number of internodes along with single cane weight, cane yield, commercial cane sugar yield, net profit and B:C ratio as compared to that of other planting geometries followed by 60-150 cm and 75-150 cm. Similarly, application of 75% RDF N inorganic + 25% N organics also recorded significantly superior all the growth parameters along with single cane weight, cane yield, commercial cane sugar yield, net income and B.C. ratio as compared to that of other nutrient management combinations except 100% RDF inorganic, where both these treatments were found par with each other.
