Abstract:
A field experiment entitled, “Assessing the impact of cow-based bio-enhancers and organic manure on quality, nutrient content-uptake and soil nutrient-microbial dynamics in kharif groundnut under organic farming” was carried out during two consecutive kharif seasons of 2021 and 2022 on loamy sand soil of Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. The nine nutrient management treatments under organic farming applied to groundnut during kharif season were laid out in randomized block design and twenty-seven treatment combinations comprising nine nutrient management treatments of groundnut through organic manure along with cow-based bioenhancer with three replications. Significantly higher quality parameters, nutrient content of groundnut were found with the application of 100% RDN through vermicompost + Panchgavya @ 4% spray at 30 and 60 DAS, while application of 100% RDN through FYM + Bijamrut (seed treatment 200 ml/kg seed) + Jivamrut @ 500 lit/ha at 30 and 60 DAS recorded significantly higher available nutrient and microbial count in soil after harvest of groundnut and organic carbon is unaffected during course of study.
