Abstract: A field experiment was conducted during 2017-18 and 2018-19 at the instructional farm of Agronomy Department, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.), and India; to study the, “evaluation of effect of organic packages and bio-products on the growth parameters, yield parameters and yield of groundnut (Arachis hypogea L) The experiment results revealed that the mean plant height (25.48 cm), number of functional leaves hill^-1 (66.85), dry matter production hill^-1 (25.97 g), mean plant spread (23.91 cm), number of branches hill^-1 (11.70), number of pods hill^-1 (30.92), weight of mature pods hill^-1 (39.53 g), 100 kernel weight (54.17 g), shelling percentage (72.96 %), dry pod yield (39.99 q ha^-1), kernel yield (29.22 q ha^-1) and haulm yield (48.70 q ha^-1) of the groundnut were significantly enhanced due to 50 kg N through vermicompost + 50 kg P₂O₅ through rock phosphate + phosphate solubilizing bacteria (PSB) (T₈) as compared to the other treatments in the pooled data of the two years. Among the different bio-products, the application of cow urine (10%) (P₂) recorded significantly higher mean plant height (24.42 cm), number of functional leaves hill^-1 (63.47), dry matter production hill^-1 (23.88 g), mean plant spread (22.77 cm), number of branches hill^-1 (10.78), number of pods hill^-1 (28.25), weight of mature pods hill^-1 (36.33 g), 100 kernel weight (53.34 g), shelling percentage (72.26 %), dry pod yield (35.69 q ha^-1), kernel yield (25.93 q ha^-1) and haulm yield (43.25 q ha^-1) of groundnut crop followed by vermi-wash (3%) (P₃) and control (P₁) in the descending order of significance in the pooled data of two years experimentation.
