Effect of organic source of nutrients on growth and growth indices of adzuki bean (Vigna angularis L.) under mid hill conditions of Himachal Pradesh

Abstract

A field study was carried out at Integrated Research Farm, Department of Organic Agriculture and Natural Farming, CSK Himachal Pradesh Krishi Vishvavidyalaya during the Kharif season of 2022, to evaluate the effect of organic sources of nutrient on growth and growth indices of adzuki bean (HPU-51). The randomized block design used in the experiment included eight treatments [T1-Beejamrit + Jeevamrit (175 l/ha) + Mulching (10 t/ ha), T2 – Beejamrit + Ghanjeevamrit (500 kg/ha) + Mulching (10 t/ ha), T3-Beejamrit + Jeevamrit (175 l/ha) + Ghanjeevamrit (500 kg/ha) + Mulching (10 t/ ha), T4- FYM (10 t/ha), T5- FYM (10 t/ha) + Ghanjeevamrit (500 kg/ha), T6- Biofertilizers (Rhizobium + PSB) + FYM (10 t/ha) + Vermiwash (225 l/ha), T7- Biofertilizers (Rhizobium + PSB) + Vermicompost (5 t/ha) + Vermiwash (225 l/ha), T8 - Absolute control]. Application of  biofertilizers (Rhizobium + PSB) + vermicompost (5 t/ha) + vermiwash (225 l/ha) resulted in significantly higher values of plant height, dry matter accumulation, absolute growth rate, unit area efficiency than absolute control. The experiment concluded that applying vermiwash with biofertilizers of Rhizobium and PSB, and vermicompost as a substitute of chemical fertilizers to provide nutrients which provided positive effect on growth and growth indices of adzuki bean ultimately gave effect to produce a good yield.
