Effect of Different Establishment Methods and Nutrient Management Practices on Growth, Yield and Economics of Rice (Oryza sativa L.)

Abstract

The field experiment was conducted during 2018 Kharif at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya to study the Effect of different establishment methods and nutrient management practices on growth, yield and economics of rice (Oryza sativa L.). The experiment laid out in a split plot design with three replications. The treatments comprised of three rice establishment methods viz., semi dry, drum seeding & transplanting and five nutrient management practices. Among establishment methods, growth and yield parameters such as LAI at 60 DAS, plant height, dry matter production at harvest, panicles m-2, panicle weight, test weight, grain and straw yields recorded were statistically analyzed at par with each other. Further between nutrient management practices, application of 150% RDIF recorded significantly higher LAI at 60 DAS, plant height, dry matter production at harvest, panicles m-2, panicle weight, test weight, grain and straw yields as compared to rest of the nutrient management practices. Further semi dry and drum seeding of rice recorded higher B:C ratio (2.15) over transplanting of rice (2.10). Similarly, 150% RDIF recorded higher B:C ratio (2.37), but was closely followed by 100% RDIF (2.22).
