Influence of methods of cultivation and fertility levels on productivity and profitability of rice hybrids

A field experiment was conducted during rainy season of 2010 at ZARS, V. C. Farm, Mandya, coming under the jurisdiction of University of Agricultural Sciences, Bengaluru, Karnataka to study the economic analysis of rice hybrids grown under different methods of cultivation and fertility levels in Cauvery command area. The experimental soil was red sandy loam in texture, having soil pH of 6.05 and low in organic carbon content (0.42%). The experiment consisted of 18 treatment combinations of two methods of cultivation, three rice hybrids and three fertility levels were laid out in split-split plot design with three replications. The study of the investigation revealed that significantly higher grain yield was obtained under SRI method of planting (7669 kg/ha) with rice hybrid Arize (7778 kg/ha) at 150% RDF (7793 kg/ha) than conventional method of cultivation. The SRI method of planting with rice hybrid Arize (6444) at 150% RDF recorded significantly higher net income and B: C ratio (Rs. 50,886/ha and 1.62, respectively) compared to conventional method of cultivation.
