A field experiment was conducted to study the effect of soil fertility constraints based nutrient management on groundnut (Arachis hypogaea L.) at Kurthkoti-2 micro-watershed, Gadag. The RCBD was imposed with ten treatments replicated thrice. The non-gravelly, clay textured black soils belong to Typic Chromustert with moderately alkaline pH having low to medium fertility status (N, P2O5, K2O and S: 180, 20.5, 351 and 17.5 kg ha-1) significantly responded in terms of groundnut growth and yield during kharif 2018. Soil application of 175 % RD N, P2O + 75 % K2O nutrients recorded the significantly higher growth parameters i.e. plant height (19.86, 35.00 and 45.80 cm), number of branches plant-1 (5.74, 6.60 and 6.74) and dry matter per plant (6.78, 17.43 and 26.85 g) at different stages (30, 60 DAS and at harvest respectively) along with significant higher yield attributes i.e. number of pods plant-1 (22.46), pod weight plant-1 (11.62 g), shelling per cent (85.34 %) and test weight (41.66 g). Further the same treatment recorded significantly higher pod (2898 kg ha-1) and haulm (3848 kg ha-1) yield with an increase in the oil (44.67 %) and protein (22.20 %) contents in kernel.
