Abstract:
The experiment was conducted during 2018-19 and 2019-20 at HRS, AAU, Kahikuchi experimental farm where okra (Arka anamika) was grown during summer season. There were 9 treatments. Okra fruit yield was the highest under the treatment with dual culture of Azospirillum and PSB along with optimal compost. The highest value of available N, P and K in soil was observed under dual culture of Azospirillum and PSB (T₆) along with optimal compost. Soil health indicators/attributes such as Microbial biomass carbon and enzyme activities (dehydrogenase and urease) were found to be significantly higher in soil when treated with dual culture of Azospirillum and PSB along with optimal compost (T₆). Acid phosphatase activity was found to be the highest in T₄ (PSB along with optimal compost). Thus, this study has confirmed that the use of dual culture of Azospirillum and PSB along with optimal compost is more effective in okra.
