Abstract:

A Field experiment was conducted during kharif season 2019-2020 at Crop Research Farm Department of Agronomy, SHUATS, Prayagraj, UP. To study the “Effect of Phosphorous, Zinc and Iron levels on growth and yield of kharif maize (Zea mays L.)”. The experiment was laid out in Randomized block design with three replication and 9 treatments out of these application of Phosphorous 60 kg/ha + zinc 25 kg/ha + Fe 25 kg/ha in treatment 9 given maximum plant height (199.03cm), No. of leaves (12.73), Plant dry weight (176.23 g), No. of cob/plant (1.84), Cob length (20.14cm), No. of Grain row/cob (17.10), No. of grain/row (24.13), No. of grain/cob (412.73), Test weight (318.0g), Grain yield (2.77t/ha), Straw yield (5.23 t/ha), Harvest index (34.66%) and the same trend is follow on economic of the experiment i.e. the treatment 9 recorded maximum Gross return of Rs. 88330/ha, Net return Rs. 38632/ha and B:C 1.78. However, the treatment 8 (P 60 kg/ha + zinc 25 kg/ha + Fe 20 kg/ha) have the maximum CGR (14.56 g/m2 /day) and RGR (0.010 g/g/day).
