Abstract

The field experiment was conducted during three seasons (Kharif, Rabi and Summer) in the two consecutive years 2021-22 to 2022-23 at Instructional Research Farm, Department of Agronomy, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India. The experiment was laid out in split plot design with 24 treatment combinations of six different nutrient management practices and 4 cropping system. The allocation of various treatments to different plots was done randomly with three replications. Under main plot, NM1 (100% organic), NM2 (50% Organic NM + NF inputs Beejamrit + Ghanjeevamrit + Jeevamrit), NM3 (50% Organic NM + 50% Inorganic NM), NM4 (25% Organic NM + NF inputs Beejamrit + Ghanjeevamrit + Jeevamrit + 25% Inorganic NM), NM5 (Farmer practices), NM6 (100% Inorganic NM). CS1 (Soybean-wheat), CS2 (Soybean-berseem), CS3 (Soybean-mustard-green gram), CS4 (Soybean-lentil-sorghum) allotted under sub-plot. The results revealed that biological properties of soil were significantly enhanced by different nutrient management practices and cropping system during both the years of experimentation. The bacterial (46.81 × 105 cfu g-1 soil) and fungal population (42 × 103 cfu g-1 soil) was found maximum under 100% organic nutrient management followed by INM (25% + 25%). Whereas the actinomycetes population was maximum (14 × 102 cfu g-1 of soil) under INM (25% organic + 25% inorganic + NF inputs) followed by 50% organic + NF inputs with soybean-mustard-green gram cropping system.

Keywords

Soybean based cropping system, nutrient management, bacteria, fungi, and actinomycetes

Conclusion

Based on the results it can be concluded that the microbial population slightly changes from the initial status due to different nutrient management practices and cropping system. The bacterial and fungal population was maximum under 100% nutrient management while the actinomycetes population was maximum under INM (25% organic +25% inorganic) + NF inputs with soybean- mustard - green gram cropping system.
