Abstract

The purpose of this study was to investigate the effects of nitrogen and time irrigation on the roots and yield. A test was conducted in a split plot randomized complete block design, Main plots consisted of four irrigations (waterlogging, irrigation 60, 70 and 100% evaporation) and sub-plots four levels of nitrogen (0, 60, 80 and 120 kg/ha). The results showed high and close to the roots activity at 70 and 100% water evaporation and nitrogen at 120 and 80 kg/ha. The highest yield office was at irrigation 70% and nitrogen 80 kg/ha. The yield was not significant with flood irrigation and nitrogen@ 120 kg/ha.
