ABSTRACT

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 ( 122408 ha-181404 ha-1 and 2.99, respectively)  as compared to other genotypes. 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.
