Performance of Rice (Oryza sativa L.) Cultivars under Nutrient Management Practices in Eastern Plateau and Hills Zone of India

Aim: To study the effect of rice cultivars and nutrient management practices on growth parameters, yield attributes, yield, nitrogen uptake and comparative economics.

Study Design: Three varieties and four nutrient management are treated in split plot design with plot size of 4m × 3m. The treatments comprised of three varieties, V1: CR Dhan – 206, V2: CR Dhan 210 and V3: CR Dhan 602 were laid out in main plot and four nutrient management comprised of N1: 100% Recommended dose of nitrogen (RDN) through fertilizer, N2: 50% RDN through fertilizer + 50% RDN through FYM, N3: 50% RDN through fertilizer + 50% RDN through azolla and N4: 50% RDN through FYM + 50% RDN through azolla are tested in subplot with replicate thrice.

Place and Duration of Study: The field experiment conducted at Chatabar farm, Faculty of agricultural sciences, Siksha ‘O’ Anusandhan University, Bhubaneswar, Odisha during kharif season, 2022.

Results: The experimental result from this experiment indicated that CR Dhan 206 cultivate with 100% RDN through fertilizer produced maximum plant height, number of filled grain per panicle, panicle length, yield (grain and straw), harvest index, nitrogen uptake by grain and straw, net return and return per rupees investment.

Conclusion: Cultivation of CR Dhan 206 with 100% RDN (80-kg/ha) produced highest grain yield, net return and return per rupees investment.
