Influence of Boron, Zinc and Iron on Growth and Yield of Summer Maize (Zea mays L.)

A field trial was conducted on the crop maize in the during Zaid season of 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The trai was carried out to research “Influence of boron, zinc and iron on growth and yield of summer maize. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.9), available N (270.81 kg/ha), available P (11.5 kg/ha) and available K (215.9 kg/ha). The trail was laid out in Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation.The results showed that the foliar application of boron 0.6% along with 25kg/ha of zinc and 25kg/ha of iron (treatment no. 8) was recorded significantly maximum plant height (205.79 cm), Plant dry weight (179.67 g/plant), Crop growth rate (28.11 g/m2/day) No. of leaves/plant (13.93), No. of cob/plant(2.07), No. of row/cob (14.67), No. of seeds/row (26.00), Test weight (238.0 g), Grain yield (5.40 t/ha), Straw yield (9.60 t/ha), Harvest index (35.97), Gross returns (122400.0 INR/ha), Net return (77210.0 INR/ha) and benefit cost ratio (1.71) as compared to other treatments.
