Abstract:

Field experiments/On Farm trial (OFT) were conducted at Farmers field of village, Halsi, Lakhisarai  under the supervision of ICAR-Krishi Vigyan Kendra, BAU, Bihar, India in 2012-13 and 2013-14.To established a uniform plant stand for the maximum yield and net return ultimately for the drudgery reduction. The experimental trial was laid out in a Randomized block design replicated four times (Number of Farmers) with six treatments comprises of transplanted rice (Farmers practices), system of rice intensification (SRI) square transplanted, DSR- Zero-tillage (dry seeding), direct seeded rice (DSR)- broadcasting (dry seeding), DSR- Drum seeded (dry seeding) and DSR- wet seeded (sprouted seeding). Among the different establishment method, SRI planting significantly influenced the growth, yield attributing characters and yield, but relatively was on par with transplanted rice. The maximum plant height, number of tillers m^-2, panicle length, leaf area Index (LAI) , number of filled grains panicle^-1, number of unfilled grain panicle^-1,test weight, grain yield (5712 kg ha^-1), straw yield (7950kg ha^-1) and net return (Rs. 50,409.30 ha^-1) were recorded under SRI (square transplanted) but which were on par with transplanted rice and DSR- Zero-tillage while benefit cost ratio were significantly highest (2.56) under DSR- Zero-tillage. Lowest grain yield, straw yield and gross return were observed under DSR- broadcasting and lowest net return were recorded under DSR- wet planted (sprouted seeds) and lowest B:C ratio were found under Transplanted rice. System of rice intensification (SRI) having higher yield followed by puddled transplanted rice, DSR- drum seeder (sprouted seed) and DSR- zero-tillage. DSR- zero-tillage is a viable, long-lasting and appropriate substitute to puddled transplanted rice and to be the most profitable methods with minimize the cost of cultivation.
