Abstract

In order to study the effects of level and time of NITROGEN fertilizer application and CUTTING HEIGHT on YIELD and YIELD component of RICE RATOONing (Tarom genotype, a traditional cultivar in Mazandaran Province, Iran). The experiment was conducted in a factorial design based on randomized completely block design with 3 replications at RICE Research Institute of Iran. Amol. The level of NITROGEN fertilizer in four levels (0, 11.5, 23 and 34.5 kg N ha-1), time of NITROGEN application in two levels (immediately and one month after main crop harvest) and CUTTING HEIGHT in three levels (0, 20 and 40 Cm above ground) were the treatments. The results showed that different levels of N fertilizer did not significantly affect RATOON YIELD, harvest index, panicle number per squer meter, grain number per panicle, filled grain number and 1000-grain weight but N applied immediately after main crop harvest significantly affect RATOON YIELD and grain number per panicle. CUTTING HEIGHT had a significant effect on RATOON plant height, grain number per panicle and filled grain number. RATOON YIELD, grain number per panicle and filled grain number was significantly higher when the main crop was ground cut at 40 Cm above ground.
