A field experiment was conducted to access the “Effect of various nutrient management practices on growth dynamics, husk and seed yield of isabgol” during rabi season of 2021-22 under the Department of Agronomy, College of Agriculture, IGKV, Raipur, (C.G.) under the title- “Impact of different nutrient management practices on growth dynamics, husk and seed yield of isabgol”. There present total ten treatment combinations, comprises of T₁ (Control), T₂ (FYM @ 10 t ha^-1, T₃ [100% RDN through inorganic (50:25:30) NPK kg ha^-1], T₄ (75% RDN through inorganic + 2.5t ha^-1 FYM), T₅ (50% RDN through inorganic + 5 t ha^-1 FYM), T₆ (100% RDN through inorganic + Azospirillum @ 5 kg ha^-1 + PSB @ 3 kg ha^-1), T₇ (75% RDN through inorganic + Azospirillum @ 5 kg ha^-1 + PSB @ 3 kg ha^-1), T₈ [50% RDN through inorganic + 0.5% foliar spray (19:19:19) at 35 and 65 DAS], T₉ [5 t ha^-1 FYM + 0.5% foliar spray (19:19:19) at 35 and 65 DAS], T₁₀ [100% RDN through organic sources @ (1/3^rd FYM + 1/3^rd vermicompost + 1/3^rd neem cake)]. The data of the experiment were analyzed and it is clearly revealed that application of (100% RDN through inorganic + Azospirillum @ 5 kg ha^-1 + PSB @ 3 kg ha^-1) significantly increases plant height (41.40 cm), number of leaves per plant (37.53), number of spikes per plant (18.01), number of seeds per spike (62.01), and application of (100% RDN through inorganic + Azospirillum @ 5 kg ha^-1 + PSB @ 3 kg ha^-1) significantly produced maximum husk yield (298.36 kg ha^-1), and seed yield (566.50 kg ha^-1) during investigation in Chhattisgarh plains.
