Effect of integrated nutrient management (INM) on growth parameters of timely sown wheat (Triticum aestivum L.)

An experiment was conducted during rabi season of 2018-19 and 2019-20 at 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 growth parameters were significantly influenced by different integrated nutrient management at successive growth stages of crop except 30 DAS. Crop growth rate increased progressively with increase in duration of wheat crop. Crop growth rate was maximum up to 90 DAS and thereafter, a slow increase in growth was obtained up to harvest. Among the integrated nutrient management, 75% RDN+25% N through (poultry manure) + ZnSO4 @ 25 kg ha-1 + Sulphur @ 40 kg ha-1 proved to found better as regarding of plant height (83.90, 95.90 cm), dry matter accumulation (1073.50, 1111.00 g m-2) and number tillers per (334.66, 341.36 m-2) at harvest stage in respective years. Whereas leaf area index was measured maximum at 60 DAS after than it declined. The minimum growth parameters were observed under control.
