Impact of Different Nutrient Management Practices on Soil Physico-chemical Properties and Economics of Soybean in Kymore Plateau and Satpura Hills Agro-climatic Zone

The field trial was conducted at Krishi Nagar Farm, Department of Agronomy, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India, during the kharif season of 2021. The field experiment comprised six treatments and was conducted in a randomized block design (RBD) with four replications. Results showed a slight reduction in soil pH in treatments 100% Organic NM, 50% Organic NM + NF inputs BJG, 50% Organic + 50% Inorganic NM, and 25% Organic + NF inputs BJG + 25% Inorganic NM, while an increase was observed in T5 and T6 compared to the initial soil status. Changes in EC and OC under various treatments were not significant, but available N, P, and K levels varied significantly across treatments, showing increased values from the initial soil status. The treatment with 100% Organic NM had the highest cost of cultivation (Rs.31624), gross monetary return (Rs. 58605/ha), net monetary return (Rs. 26982/ha), and B:C ratio (1.85), followed by the treatment with 50% Organic NM + NF inputs.
