Effect of Different Nitrogen Levels and Fym on Growth and Yield of Wheat (Triticum Aestivum L.).

The experiment was carried to determine the Effect of different Nitrogen levels and FYM on Growth, and Yield of wheat (Triticum aestivum L.) during rabi (winter) season 2021-22 at the Agronomy Research Farm, Agriculture Department, Himgiri Zee University, Selaqui, Dehradun Uttarakhand. Experiment was conducted on wheat variety of W-75.The soil of experimental site was sandy loam intexture pH 7.27, Electrical conductivity (EC) 0.18 dSm^-1, Organic Carbon (4.9 g Kg ^-1) low, alkaline KMnO₄ N 265.30 Kg ha^-1, Olson-P 24.88 Kg ha^-1 ammonium acetate extractable K 108.70 Kg ha^-1.The treatments comprised of 4 level of nitrogen N₁ (60 kg N/ha), N₂ (90 kg N/ha), N3 (120 kg N/ha), N4 (150 kgN/ha) and one level of farm yard manure at which FYM was applied@ 6 tonnes ha^-1 with the three levels of nitrogen (60, 90 and 120 kg ha^-1) in the mode of soil application. There were 8 treatments combinations T₁ Control (without fertilizer), T₂ (60 kg N + 60 kg P²O⁵ + 60 kg K²O ha^-1), T₃ (90 kg N + 60 kg P²O⁵ + 60 kgK²O ha^-1), T₄ (120 kg N + 60 kg P²O⁵ + 60 kg K²O ha^-1), T₅ (60 kg N + 60 kg P²O⁵ + 60 kg K²O + FYM 6 tones ha^-1 a) T₆ (90 kg N + 60 kg P²O⁵ + 60 kg K²O + FYM 6 tones ha^-1), T₇ (120 kg N + 60 kg P²O⁵ + 60 kg K²O + FYM 6 tones ha^-1), and T₈ (150 Kg N + 60 kg P²O⁵ + 60 kg K²O ha^-1) replicated thrice in a randomized block design with in 24 plots. The results revealed that the application of 120Kg Nitrogen with Farmyard manure @ 6tones ha^-1 gave the maximum plant height, number of tillers m^-2, dry matter accumulation, and yield attributing characters, grain yield, straw yield, and biological yield. The maximum plant height 86.75 cm, number of tillers 93.68 m^-1row length, and dry matter accumulation 751.75 g m^-1 row length respectively was recorded in T₇ where 6 t ha^-1 FYM was applied with 120 Kg nitrogen in the experimental year followed by T₈ where 150 kg nitrogen was applied with recommendedP and K. The similar trends were also recorded in the grain, straw and biological yield. Maximum grainyield (37.63 q ha^-1), straw yield (50.36 q ha^-1) and biological yield (87.99 q ha^-1) in the treatment T7 where 6 t ha^-1 FYM was applied with the combination of 120 Kg N ha^-1 which were statistically at par with the treatment T8 (36.20, 48.66 q/ha and 85.19 q ha^-1 respectively) where 150 kg N ha^-1 was applied.
