Abstract:
Results of the field experiment entitled “Studies on zinc and iron enrichment through ferti-fortification in groundnut (Arachis hypogaea L.) genotypes” was conducted during rabi season of 2014-15 at Agronomy field unit, College of Agriculture, UAS, Raichur are discussed in this paper. 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 leaf area index (1.79 at harvest), kernel yield and shelling percentage (1934 kg ha-1 and 72.77%) and Fe uptake by kernels, haulm and their total uptake (357.12, 517.71 and 874.83 g ha-1, respectively) as compared to other genotypes. Among the micronutrients, soil (25 kg ha-1) and foliar (0.5%) application of ZnSO4 recorded significantly higher leaf area index (2.10 at harvest), kernel yield (2051 kg ha-1) and shelling percentage (73.21 %) as compared to the other treatments. Whereas, uptake of Fe in kernels, haulm and their total uptake. Significantly higher uptake of Fe in kernels, haulm and total uptake of Fe in groundnut was recorded with soil (25 kg ha-1) and foliar (0.5 %) application of FeSO4 (427.56, 701.62 and 1129.18 g ha-1, respectively) over other treatments.
