An experiment was conducted at ICAR - Krishi Vigyan Kendra, Hadonahalli, Doddaballapur taluk, Bengaluru Rural district, Karnataka during the years 2020 and 2021 to evaluate the impact of bio-stimulants on growth and yield of cowhage. Experiment consists of soil and foliar application of humic acid, amino acid, sea weed extract, microbial consortia based bio- stimulants. The experiment was conducted by adopting randomized complete block design (RCBD) with 9 treatments in three replication. Maximum plant height (315.3 cm), number of branches (8.18), leaf area (18101 cm²), leaf area index (5.03), days to 50% flowering (95.23), number of flowers per inflorescence (10.72), days taken for maturity (190.23), pod length (10.23 cm), pod width (2.15 cm), pod weight (6.43 g), number of pods per plant (38.55), seed weight per plant (154 g plant^-1) and seed yield (43.02 q ha^-1) was recorded with RDF+ foliar application of humic acid based bio-stimulant. Lower growth and yield attributes were found in plants supplied only with recommended dose of fertilizers.
