Summary:A field experiment was conducted during rabi season of 2014-15 at Agronomy field unit, College of Agriculture, University of Agricultural Sciences (UAS), Raichur to study the effect of zinc and iron fertifortification on growth, pod yield and zinc uptake of groundnut genotypes. The soil of the experimental site was deep black, clay in texture with pH 8.4, deficient in DTPA extractable zinc and iron. Three groundnut genotypes in main plots and seven micronutrient treatments comprising of one control and three each of zinc and iron as soil, foliar and both were assigned in the sub-plot in a split-plot design replicated thrice. Results revealed that the groundnut genotype ICGV-00351 recorded significantly higher plant height and leaf area at harvest (40.05 cm and 5.40 dm2 plant-1, respectively), pod yield (2656 kg ha-1) and Zn uptake by kernels, haulm and total (59.29, 130.46 and 189.75 g ha-1, respectively) when compared to other genotypes. Among the micronutrients soil (25 kg ha-1) and foliar (0.5 %) application of ZnSO4 recorded significantly higher plant height and leaf area at harvest (42.09 cm and 6.30 dm2 plant-1, respectively), pod yield (2656 kg ha-1) and Zn uptake by kernels, haulm and total (67.42, 153.61 and 221.03 g ha-1, respectively) when compared to other treatments.
