A field experiment was conducted at Post Graduate Research Farm, College of Agriculture, Kolhapur during Kharif season of 2017-18 to know the effect of foliar nutrition on growth and uptake of macro and micro nutrients by groundnut (Arachis hypogaea L.) and post harvest status of soil. The experiment was laid out in a randomized block design with three replications and seven treatments in which treatments comprised of seven treatments viz., absolute control, GRD, GRD+ water spray, GRD+19:19:19 spray (2 %), GRD+Ca(NO3)2 spray (2 %), GRD+Micro. gr.II spray (0.25 %) and GRD+Schoenite spray (1 %), respectively. The foliar nutrition was done at 45 and 60 DAS. Among the foliar treatments, significantly highest plant height (21.26 cm plant-1), number of nodules (95 plant-1) and number of branches (9.10 plant-1) was recorded by treatment 2 % foliar spray of Ca(NO3)2. The total uptake by groundnut crop at harvest of all the macro (N, P, K, Ca, Mg and S) and micro nutrients (Fe, Mn, Cu, Zn and B) viz., nitrogen (142 kg ha-1), phosphorus (23.33 kg ha-1), potassium (82 kg ha-1), calcium (63 kg ha-1), magnesium (65 kg ha-1), sulphur (21.90 kg ha-1), iron (2621 g ha-1), manganese (748 g ha-1), zinc (302 g ha-1), copper (190 g ha-1) and boron (64.9 g ha-1) was highest in treatment 2 % foliar spray of Ca(NO3)2. The available nutrient status after harvest of crop did not differ significantly due to different treatment of foliar spray.
