Effect of Different Zinc Fertilization Methods on Growth and Productivity of Summer Maize (Zea mays L.)

Background: In recent times the micro nutrients were reported to influence crop growth and productivity. Among them zinc is a vital micronutrient for plants, humans animals. However, use efficiency mainly depends on methods of fertilization. Although there are many ways deliver crops such as soil application, foliar sprays, fertigation, seed priming root dipping, etc. The right method proportion apply fertilizer in southern Odisha not yet standardized. Hence, present investigation was undertaken choose most efficient fertilization this agro climatic zone. Methods: study conducted summer maize during 2022 at PG Experimental farm, M.S.Swaminathan school agriculture. experiment laid out randomized block design with 10 treatments 3 replications. consisted T1, control (no application zinc); T2, ZnSO4.7H2O rate 6.25kg/ha; T3, 12.5kg/ha; T4, 25kg/ha; T5, 0.5% ZnSO4.7H2O; T6, 1.0% T7, 1.5% T8, knee high stage, T9; height stage tasseling; T10, tasseling grain filling stage. Result: results showed that 25kg/ha through could be recommended farmers growing season achieve higher productivity
