Influence of Vermicompost, Neem Cake and Biofertilizers on Growth, Yield and Economics of Green Gram (Vigna radiata L.)

Abstract

The findings of the present investigation titled, Influence of vermicompost, neem cake and biofertilizers on growth, yield and economics of Green gram (Vigna radiata L.), carried out during the kharif season of 2023 at the Baba Farid Institute of Technology's Crop Research Farm in Dehradun. It is situated between latitude 30.3436 and longitude 77.9367. The Shivalik hills and the lower Himalayas in the Indian states of Uttarakhand, Himachal Pradesh, and Haryana are home to the extraordinarily wide and lengthy valley known as the doon valley. The investigation was conducted in Randomized Block Design consisting of 10 treatment combinations with 3 replications and was laid out with the different treatments allocated randomly in each replication. Application of vermicompost (1.25t/ha) + neem cake (0.625 t/ha) + rhizobium (10 g/kg seed) + PSB (10 g/kg seed), recorded maximum plant height (45.44 cm),  Number of branches per plant (6.08), number of nodules/plant (11.05), dry weight (g/plant) (6.57), no. of pods/plant (28.38), seeds per pod (10.13), test weight(g) (38.14), grain yield (1094.06 kg/ha), stover yield (1523.95 kg/ha) and biological yield (2618.01 kg/ha). Where the maximum gross return (101249.80 INR/ha), net return (76043.75 INR/ha) and B:C ratio (3.02) were also recorded with application of vermicompost (1.25 t/ha) + neem cake (0.625 t/ha) + rhizobium (10 g/kg seed) + PSB (10 g/kg seed).
