Effect of integrated nutrient management practices on yield attributes, yield and economics of timely sown wheat (Triticum aestivum L.)

An experiment on “Effect of integrated nutrient management practices on yield attributes, yield and economics of timely sown wheat (Triticum aestivum L.)’’ was carried out during winter season of 2018-19 and 2019-20 at the Agronomy Research Farm, ANDUA & T Kumarganj, Ayodhya (U.P.) India. The experiment consists of fourteen treatments were laid out in Randomized Block Design (RBD) with three replications. As per experiment the results revealed that the yield parameters were significantly influenced by different integrated nutrient management practices except test weight. The maximum yield attributes parameters viz. number of spikes (304.24, 310.32 m-2), spike length (10.30, 10.35 cm), number of grain spike-1 (42.30, 42.73 spike-1) were observed with the application of 75% RDN + 25% N through (poultry manure) + ZnSO4 @ 25 kg ha-1 + Sulphur @ 40 kg ha-1, which was at par with rest of the integrated nutrient management practices and significantly higher over control (T14) treatments. However, the maximum grain and straw yield (45.30, 47.10 q ha-1 and 62.05, 64.00 q ha-1, respectively) and biological yield (107.35, 111.10 q ha-1) were achieved when applied 75% RDN + 25% N through (poultry manure) + ZnSO4 @ 25 kg ha-1 + Sulphur @ 40 kg ha-1, which was at par with T9, T11, T1, T7, T12 and T8 treatments, respectively. While significantly superior over rest of the treatments, whereas the harvest index did not influenced by INM. In case of economic of different treatments, the maximum gross return (Rs. 95752.00 and 103467.00 ha-1) and were computed under 75% RDN + 25% N through FYM + ZnSO4 @ 25 kg + Sulphur @ 40 kg ha-1. However, maximum net return (Rs. 56182.00 and 61440.00 ha-1 and B:C ratio (1.63 and 1.69) was recorded with the application of 100% RDN (Recommended dose of Nitrogen) and minimum B:C ratio was noted under control (T14) treatments.
