Abstract
A two years investigation conducted at Instructional Farm, RCA, MPUAT, Udaipur during Rabi 2022-23 and 2023-24 to evaluate the impact of different methods of zinc and iron through soil and foliar application on growth attributes of bread wheat (Triticum aestivum L). The soil of experimental site was slightly alkaline in soil reaction (8.24 and 8.25) and clay loam in texture. The experiment was laid out under FRBD with three replications. The experiment comprised of 5 levels of soil applied Zn and Fe, S1 (10 kg ZnSO4 ha-1) S2 (20 kg ZnSO4 ha-1), S3(25 kg FeSO4 ha-1), S4(50 kg FeSO4 ha-1) S5(10 kg ZnSO4 ha-1 + 25 kg FeSO4 ha-1) and three levels of foliar applied zinc and iron namely F1 (0.5% ZnSO4 ha-1), F2 (0.5% FeSO4 ha-1) F3 (0.5% ZnSO4 ha-1 + 0.5% FeSO4 ha-1) at two different growth stages (30 DAS and 45 DAS) along with one absolute control. The result showed that soil application and foliar application of zinc and iron increased the growth parameters of crop significantly. The result showed that among control verses rest treatments, combined soil applied zinc and iron @10 kg ZnSO4 ha-1+ 25 kg FeSO4 ha-1 (S5) recorded highest dry matter accumulation (g) at 90 DAS and at harvest, plant height (cm and number of total tillers (0.5 m2) at harvest in crop over control.
