Effects of Pyridoxine and Different Levels of Nitrogen on Yield and Yield Components in Corn (Zea Mays L. Var . SC 704)

The Study effects of different level of nitrogen , pyridoxine and their interactional effects on physiology of growth , yield and yield component of seed corn (Zea mays L. var. SC. 704) in year 1385 . A field experiment was conducted on corn (Zea mays L. var. SC.704) in the form of split plot in three replication , for this purpose of nitrogen in three level (90,140,190Kg/ha) along with pyridoxine in three level (0,0.01%,0.02%). the treatment of pyridoxine inoculation with nutriment for this reason , at first step corn seed soaking pre - sowing seed soaking treatment with pyridoxine for 8 hours and treatment of water - soaked seeds were control in lab. the resoults of this study show that nitrogen and pyridoxine have significant effect on the yield and yield components probabely it has positive effect on the process growing of root, lead to in crease absorb of nutriment , especially absorb the nitrogen and it lead to increase the wight of dry material in different organs of plan . In general 0.02 % Pyridoxine treatment and 190 Kg/ha nitrogen gave maximum value for growth and yield parameters, likewise use of prydoxine lead to improvement the situation of indices physiology of measurd growth in this experiment.
