Title : Effect of soil and foliar application of zinc and iron on Yield, Quality and Economics of Maize

Abstract :

A field experiment was conducted during two consecutive Kharif, seasons of 2018 and 2019 at Instructional Farm, Rajasthan College of Agriculture, Udaipur. The experiment was laid out under a split-plot design with three replications, including seven levels of soil application in main plots and four levels of foliar spray in the subplot. Significantly highest grain, stover and biological yield (4068.47, 6532.07 and 10600.54 kg ha-1) in the main plot under treatment 25 kg ZnSO4 ha-1 + 25 kg FeSO4 ha-1. In subplot highest grain, stover and biological yield (4068.47, 6532.07 and 10600.54 kg ha-1) were observed under treatment 0.5% ZnSO4 ha-1 + 0.5% FeSO4 ha-1. The interactive effect of soil and foliar application of zinc and iron significantly increases the grain and stover yield. The highest grain and stover yield (4609.45 and 7749.30 kg ha-1) was found with treatment combination S6F3. Harvest index was found non-significant in both soil and foliar application. The highest protein content (11.08 % and 11.07 %) was found in S6 and F3 treatments in the main and subplot, respectively. The highest net return and B:C ratio were found under soil application of 25 kg ZnSO4 ha-1 + 25 kg FeSO4 ha-1 (₹ 61986.1 and 2.53) and foliar application of 0.5% ZnSO4 ha-1 + 0.5% FeSO4 ha-1 (₹ 63479.1 and 2.70).
