Abstract:
A field experiment was conducted during kharif 2020 at SMOF (SHIATS Model Organic farm), Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of the experimental field is sandy loam in texture, nearly neutral in soil reaction (pH 7.4). The treatments consisted of Biofertilizers viz., Azospirillum (seed inoculation @ 25 g/kg), Rhizobium (seed inoculation @ 25 g/kg), Azospirillum + Rhizobium (seed inoculation @ 25 g/kg) and vermicompost viz., vermicompost (3 t/ha), vermicompost (6 t/ha), vermicompost (9 t/ha) whose effect is observed in cowpea (Gomathi). The experiment was laid out in Randomized Block Design with ten treatments replicated thrice. The treatment with application of vermicompost (6 t/ha) + Rhizobium + Azospirillum also recorded significantly higher in plant height (40.20 cm), number of branches (8.79), and plant dry weight (88.93g). The treatment with application of vermicompost (6 t/ha) + Rhizobium + Azospirillum also recorded significantly higher in Number pobs per plant (33.72), and Number of grains/pod (9.57) and crop growth rate (0.94 g/g²/day) and straw yield (2926.87 kg/ha). The maximum gross return (96521.2 INR/ha), net return (61526.2 INR/ha) and B:C ratio (1.76) is recorded in treatment with application of vermicompost 6t/ha + Rhizobium + Azospirillum.
