The Effect of Pyridoxine and Different Levels of Nitrogen on Physiological Indices of Corn(Zea Mays L.var.sc704)

Authors: babak paykarestan, Gholamreza Farrokhi


One field experiment was conducted on corn (Zea mays L.Var. SC 704) to study the effect of three different basic levels of nitrogen (90, 140and 190 Kg/ha as urea) with 0.01% and 0.02% pyridoxine pre-sowing seed soaking for 8 hours. Water-soaked seeds were treated as controled. biomass production was recorded on 45, 70 and 95 days after sowing. Total dry material (TDM), leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) was calculated form 45until 95 days after sowing. Yield and its components such as kernel yield, grain weight, biologic yield, harvest index and protein percentage was measured at harvest. In general, 0.02% pyridoxine and 190 Kg pure nitrogen/ha was shown gave maximum value for growth and yield parameters. N190 + 0.02 % pyridoxine enhanced seed yield and biologic yield by 57.15% and 62.98% compared to 90kg N and water – soaked treatment.
