Soil health indicators such as soil physico-chemical properties, total bacterial count, microbial enzyme activities were monitored at different crop growth stages (such as before ploughing, after transplantation (0 DAT), max tillering (45 DAT), flowering (60 DAT) and maturity (90 DAT) of rice variety Pusa Basmati 1. The treatment comprises green manure Sesbania rostrata and inorganic fertilizers for organic and conventional respectively. Moreover, field was cultivated with rice variety Pusa Basmati I. Total bacterial count; microbial enzyme activities (i.e Dehydrogenase, Fluorescein diacetate and Urease) and soil organic C and N significantly enhanced with crop growth and were maximum at maturity 90 DAT. Conversely, inorganic fertilizers did not affect soil C and N. However soil pH and alkaline phosphatase (AP) enhanced with crop growth. The calculated crop yields for organic and conventional treatments were 39.14 and 41.81 q/haˉ¹ respectively. Probable reason behind low yield in organic amendment could be short duration experiment study. Moreover, rice variety Pusa Basmati I is responsive for inorganic fertilizer. Result of this study suggest that green manure is a good source of organic nutrient to maintain soil health and crop yield but field require at least 3-5 years to under organic farming practices to give desirable results.
