Abstract

In rice based cropping system balanced fertigation through new approaches under zero till upland condition ensures high productivity and sustainability in long run. In this context, research was conducted to find out effect on nutrient uptake and nutrient use efficiency i.e. by balanced fertilization. Therefore, A field experiment was conducted at Central Rain-fed Upland Rice Research Station (CRURRS), Hazaribagh, research station in Jharkhand with the objective to determine better nutrient management practices for zero till upland rice and their effect on yield and nutrient use efficiency. The experiment was laid out in split-plot design with three replications having three rice cultivar Vandana, Anjali and CR Dhan 40 in main plot and four nutrient management practices [soil test fertilizer recommendation meter (STFR), integrated nutrient management (INM), soil test crop response equation (STCR) and recommended dose of fertilizers (RDF)] in sub-plot. Results indicated that CR Dhan 40 rice cultivar recorded the highest concentration and uptake of N, P and K in grain than other varieties. In different nutrient management practices, STFR based NPK dose (100 kg N, 44 kg P2O5, 20 kg K2O + 5 t /ha lime) recorded the highest values of N, P and K uptake in grain, straw and total followed by INM (50 % RDF+ 50% Organics) based NPK dose [40 kg N, 28 kg P2O5, 10 kg K2O (50%) + 6 t/ha FYM (50%) + lime 1 t/ha] and STCR based NPK fertilization. Therefore, based on research findings, it can be concluded that rice cultivar “CR Dhan 40” with STFR and INM based fertilization may enhance the productivity and profitability of upland rice in the Eastern regions of India.

Conclusion

Based on the research findings, it can be concluded that rice cultivar CR Dhan 40 rice cultivar recorded the highest concentration and uptake of N, P and K in grain than other varieties. The concentration and uptake of N, P and K was recorded higher in STFR and INM followed by STCR based NPK fertilization.
