Effect of different nitrogen levels on growth and yield of wheat (Triticum aestivum L.)

The present investigation entitled “Effects of Different Nitrogen Levels on Growth and Yield of Wheat (Triticum aestivum L.)” was conducted during the year 2022-2023 at the CRC in ITM University Gwalior (M.P). The experiment consisted of ten treatments T₁: Nitrogen @ 0 kg ha^-1, T₂: Nitrogen @ 20 kg ha^-1, T₃: Nitrogen @ 40 kg ha^-1, T₄: Nitrogen @ 60 kg ha^-1, T₅: Nitrogen @ 80 kg ha^-1, T₆: Nitrogen @ 100 kg ha^-1, T₇: Nitrogen @ 120 kg ha^-1, T₈: Nitrogen @ 140 kg ha^-1, T₉ : Nitrogen @ 160 kg ha^-1, T₁₀: Nitrogen @ 180 kg ha^-1 The study revealed that, among the treatments,T₉ (Nitrogen @ 160 kg ha^-1) recorded highest plant height at 30, 60, 90 and harvest (22.57 cm, 56.34 cm, 94.14 cm, 97.48 cm), total dry matter/ m2 at 30, 60, 90 and harvest (55.06 g, 446.77 g, 1062.23 g, 1117.23 g), Leaf are index at 30, 60 and 90 (0.826, 3.04 and 4.14), No. of spikelets/ spike ( 20.89), No. of grains/ spike (31.08) and test weight (44.03 g) compared to control. In the present study, it can be concluded that the T9 is the best treatment for wheat variety on basis of Growth and yield.
