A experiment was conducted at Post Graduate Research Farm, College of Agriculture, Kolhapur during kharif season of 2017 to study the effect of levels and time of potassium application on yield, quality of kharif groundnut (Arachis hypogaea L.) in Entisol. The experiment was laid out in Factorial Randomized Block Design with two replications comprising of four levels (0, 20, 30,40 kg K2O ha-1) and five time of application (Sowing, flowering, pegging) of potassium. The results revealed that successive increase in levels of potassium showed significant effect on yield and yield attributes of groundnut crop, along with quality. Significantly highest dry pod, kernel and haulm of groundnut were increased significantly with increasing levels of potassium and highest yield (30.08, 21.20, 36.51 q ha-1, respectively) was recorded by application of 40 kg ha -1 K2O. The oil content and oil yield of groundnut was significantly highest (49.40 %) and (1047.33 kg ha-1) with application of 40 kg K2O ha-1. Effect of time of potassium application and interactions in respect of yield of dry pod, kernel, haulm, oil content, oil yield of groundnut were found non-significant. The shelling percentage ranged 67-70 % but the effect of various treatments on shelling percentage was non-significant.
