Abstract:
A field experiment was conducted at Instructional Farm, Department of Agronomy, College of Agriculture, JAU, Junagadh to study the effect of various cow-based bio-enhancers (Panchagavya, Jeevamrut) and botanical (Banana Pseudostem sap, Seaweed extract) on summer groundnut (Arachis hypogaea L.) (Cv. TG-37A) in organic condition during summer season of 2019. The experiment results revealed that application Panchagavya as foliar spray @ 3% at 30 and 45 DAS + FYM 5 t/ha (T4) found superior in respect of the higher grain yield, straw yield, content and uptake of NPKS by pod & haulm, and total uptake of NPKS. It was found at par with treatment of FYM 10 t/ha+ Biofertilizers (Rhizobium+ PSB + KSB) (T11), 100% RDF (T2). While higher organic carbon, bulk density and Available NPKS after harvest of the Summer Groundnut were recorded under the treatment of treatment (T12) FYM 10 t/ha but it was found statistically comparable with FYM 5 t/ha + Biofertilizers (Rhizobium + PSB + KSB) (T11), Jeevamrut @ 500 L/ha with irrigation at sowing, 30 and 45 DAS + FYM 5 t/ha (T₆). However, significantly the lowest N, P, K and S content, uptake by pod and haulm, pod and haulm yield, organic carbon, bulk density and available NPKS after harvest was observed under control.
