The investigation was carried out to study the effect of zinc and iron ferti-fortification on plant height, yield and quality parameters of groundnut (Arachis hypogaea L.) genotypes. Among the groundnut genotypes, ICGV-00351 recorded significantly higher plant height and number of leaves at harvest (40.05 cm and 25.86 plant−1), nitrogen uptake by groundnut kernels, haulm and total uptake (68.69, 52.76 and 121.45 kg ha−1, respectively), gross returns, net returns and benefit cost ratio ( 122408ha−1 81404ha−1and 2.99, respectively) as compared to othergenotypes. Among micronutrients application, soil application @ 25 kg ha−1 and foliar application @ 0.5% of ZnSO4 (S4) recorded significantly higher plant height and number of leaves at harvest (42.09 cm and 27.78 plant−1), nitrogen uptake by groundnut kernels, haulm and total uptake (76.43, 57.66 and 134.10 kg ha−1, respectively), gross returns, net returns and benefit cost ratio ( 128585 ha−1 87131 ha−1 and 3.10, respectively) as compare to other treatments.
