Effect of Spraying Humic Acid and Different Types of Zinc Fertilizer on Some Growth and Yield Traits of Wheat

Abstract

A plastic pot experiment was carried out for the agricultural season 2021-2022 in the fields of the College of Agriculture-University of Anbar and located at 30° north latitude and 43° east longitude, in order to know the role of foliar spraying of wheat plants with humic acid at concentrations of 0 mg.L−1 (H0), 0.75 g.L−1 (H1) and 1.5 g.L−1(H2) and the added zinc element sprayed with concentrations: 0 mg.L-1 (Zn0), 60 mg.L−1 in the form of nano-zinc oxide (Zn1) and 120 mg.L−1 in the form of traditional zinc oxide fertilizer (Zn2). A factorial experiment was designed according to the sectors Randomized complete set (R.C.B.D) with three replications The results of the statistical analysis showed that there was a significant increase in foliar spraying with humic acid and for all concentrations, with superiority for the highest concentration, as well as when feeding with nano particles and traditional zinc, with a clear superiority of nano particle zinc in all the studied characteristics: Plant hight, leaf area, spike length, seeds yield, and zinc concentration in seeds:(61.67 cm, 24.51 dm2 plant−1, 12.33 cm, 8.05 gm, pot−1, 14.00 mg kg−1) compared to control treatment H0Zn0 :(46.00 cm, 16.13 dm, plant−1, 8.67 cm, 6.28 gm−1, 7.80 mg kg−1) respectively Start your abstract here…
