Abstract:

A field experiment was conducted during kharif season at Rajendra Agricultural University, Pusa to assess the residual impact of conjoint use of organics and chemical fertilizers on yield and nutrients uptake of wheat under rice-wheat system. Results revealed that among the organics, FYM 10 t ha-1 application, produced highest grain yield (36.38 q ha-1) followed by Straw (32.84 q ha-1), Dhaincha (GM) (28.93q ha-1) and Urd (27.61 q ha-1). Increasing levels of inorganic fertilizers also increased the wheat grain and straw yield with the maximum grain (36.34 q ha-1) and straw (51.95 q ha-1) yield was observed in 100% recommended NPK treatment. Among all the treatments, highest grain yield (41.67 q ha-1) and uptake of major nutrients i.e. N (108.37kg ha-1), P (25.45kg ha-1) and K (99.03 kg ha-1) in wheat were observed under combined application of 100% NPK + FYM. Besides this, the fertilizer use efficiency (FUE) for N, P and K was found maximum in the treatment replacing 50% of N through FYM + 50% NPK. Thus, higher yield at balanced nutrition is safe guard for soil fertility and integrated plant nutrient supply system could help in meeting the goals of balanced fertilization as well as ita reliable way for obtaining fairly high productivity with increased FUE and an alternative practice towards sustainable agriculture.
