Abstract

Continuous use of inorganic fertilizers plays a vital role in deteriorating the soil health. Use of organic manure is the best remedy for maintaining soil quality as well as productivity and replacement of mineral fertilizers. Biofertilizers are the source of microbial inoculants, which have brought hopes for developing country like India to solve problem of high cost of fertilizers. Azotobacter, PSB, KSB and Rhizobium have provided high quality products free of harmful agro-chemicals for human safety. The biological and nutritional value of vermicompost can be improved by enrichment with microorganisms and micronutrients. In this context, a field experiment was conducted during kharif season of 2019 & 2020 on calcareous clayey soil at Junagadh (Gujarat) to study the effect of vermicompost enriched with biofertilizers, bioagents and micronutrients on nutrients uptake by kharif groundnut (Arachis hypogaea L.) and soil fertility. Results indicated highest pod yield (23.05 q/ha) and haul

Conclusion

On the basis of the results obtained from the present two-year field experimentation, it can be concluded that application of vermicompost 2 t/ha enriched with biofertilizers (Rhizobium + PSB + KSB each 2 L/ha), bioagents (Trichoderma harzianum 3 kg/ha + Pseudomonas fluorescens 3 L/ha + Beauveria bassiana 3 kg/ha) and micronutrients [(Fe + Zn + Cu + Mn) Grade-V @ 40kg/ha] increased soil fertility and uptake of nutrients by groundnut and ultimately enhanced pod and haulm yields on calcareous clayey soil under South Saurashtra Agro-climatic Zone.
