The main objective of the integrated nutrient management is to maintain economic yield for a long period with little effect on native soil fertility and environmental pollution, making some changes in farmer’s awareness toward the eco-friendly technique for producing healthy food free from contaminants and insuring satisfactory economic returns. Integrated nutrient management (INM) can offer good options and economic choices to supply plants with sufficient amounts of nutrients and also can reduce the dose of chemical fertilizers, create favorable soil physiochemical conditions and healthy environment, eliminate the constraints, safeguard the soil nutrient balance in the long run to an optimum level for sustaining the desired crop productivity, and find safety methods to get rid of agriculture wastes. Therefore, the present study was conducted to assess the impacts of different INM practices namely absolute control (T1), 25 t/ha FYM (T2), NPK – 40:20:20 Kg/ha + 5 t/ha FYM (T3), NPK – 40:25:20 Kg/ha + 10 t/ha FYM (T4), NPK – 40:30:20 Kg/ha + 15 t/ha FYM (T5), NPK – 45:20:20 Kg/ha + 5 t/ha FYM (T6), NPK – 45:25:20 Kg/ha + 10 t/ha FYM (T7), NPK – 45:30:20 Kg/ha + 15 t/ha FYM (T8), NPK – 50:20:20 Kg/ha + 5 t/ha FYM (T9), NPK – 50:25:20 Kg/ha + 10 t/ha FYM (T10) and NPK – 50:30:20 Kg/ha + 15 t/ha FYM (T11) in RBD Design with three replications at Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture, RVSKVV, Mandsaur, (M.P.) during the Rabi season of 2020-2021. The result indicated that treatment T8 observed early germination, number of days taken to 50% flowering and minimum days to maturity. Treatment T8 was recorded highest values of plant height, number of branches plant-1, fresh weight, and dry weight at 45, 90, days after sowing and at harvest. Treatment T8 was recorded the highest value of number of capsule plant-1, number of seeds capsule-1, seed yield, 1000 seeds weight and harvest index.
• INM can offer good options and economic choices to supply plants with sufficient amounts of nutrients.
• INM reduce the dose of chemical fertilizers, create favorable soil physiochemical conditions and healthy environment.
• Application of chemical fertilizers with organic manures has increased nutrients availability in the soil, followed by efficient absorption and translocation in various growths.
• Supply of optimal level of nutrients by using organic manures and chemical fertilizer’s to meet the crop mandate at proper time which in turn lead to high benefit cost ratio.
• INM @ 45:30:20 kg/ha NPK+15 t/ha FYM was found suitable combination for increasing the growth, quality and yield of nigella.
