Abstract:
An experiment was conducted during summer-2019 at certified organic plot, Agronomy Instructional Farm, Department of Agronomy, Junagadh Agricultural University, Junagadh to study the “Influence of various cow-based bio-enhancers (Panchagavya, Jeevamrut) and botanicals (Banana Pseudostem sap, Seaweed extract) on growth parameters, yield attributes and economics of summer groundnut (Arachis hypogaea L.)” (Cv. TG-37A). The soil of experimental field was medium black calcareous in texture, low in organic carbon (0.59%) available nitrogen (257.00 kg/ha) and medium in available phosphorus (29.63 kg/ha), medium in available potash (254.60 kg/ha) with soil pH of 8.19. The experiment results revealed that next to 100% RDF, application of Panchagavya as foliar spray @ 3% at 30 and 45 DAS + 5 t/ha FYM were found superior in respect of the plant height and number of branches per plant, highest number of mature pods and pod weight per plant. Application of Jeevamrut @ 500 L/ha with irrigation at sowing, 30 and 45 DAS + FYM 5 t/ha enhanced number of root nodules per plant and dry weight of root nodules per plant. Economic analysis showed that maximum net returns and B: C ratio (₹ 46664/ha and 2.18) were obtained with Panchagavya as foliar spray @ 3% at 30 and 45 DAS + FYM 5 t/ha in respect with normal price. Whereas with premium price, maximum net return ₹ 74649/ha and B: C 2.76 followed by FYM 10 t/ha + Biofertilizers (Rhizobium + PSB + KSB) over control.
