Promising rice establishment methods and N management for rice-greengram system

Abstract

Field experiments were conducted during two consecutive Kharif and Rabi season of 2014-15 and 2015-16on sandy clay loam soils at agricultural research station Ragolu. The trial was conducted in split plot designwith three replications. Main plots consists four crop establishment methods viz., dry direct sown rice,sowing by Drum Seeder, machine planting, and normal transplanting. Sub plots consists four N managementpractices viz., N @80 kg ha-1, N @120 kg ha-1, N @120 kg ha-1 (66% fertilizer+33% thro’ organic), N @120 kgha-1 + FYM @ 10 t ha-1. Results revealed that, among different crop establishment methods, machinetransplanting proved as productive, Dry direct seeding emerged as remunerative and water productivemethod for rice. Regarding nutrient management, application of 120 kg N ha-1 +FYM @ 10 t ha-1 proved tobe effective N management option for realizing higher yield in rice and fallow green gram. Regardingsystem yield and system profits, dry direct sown rice-Green gram system and machine planted ricegreengramsystems with application of 120 kg N ha-1 + FYM @10 t ha-1 proved superior.
