Abstract

To study the NITROGEN effects and plant residues management on the yield of RICE RATOON, Tarom Hashemi RICE, an experiment was performed in the research farm of Islamic Azad university of Chalus in 2010. The experiment was performed as a split plot design based on completely randomized blocks design with four replications. In this experiment NITROGEN fertilizer rate was considered as the main factor in four levels (0,60,120,180 kg N ha-1) and plant residues management was considered as the secondary factor in three levels (standing with 40 cm height, lodging stubble with 40 cm height and ground cutting). Results showed that NITROGEN fertilizer rates had significant effects on grain, straw, biologic yield and the number of cluster per square meter, numbers of tiller, numbers of effective tiller, and the stem height. Highest rate of grain yield included 290 g/m2 that were related to the use of 180 kg of NITROGEN per hectare. Grain yield had a significant and positive correlation coefficient with the number of tillers in mass and the number of fertilized tillers in mass at the 1% probability level. And grain yield had a significant and positive correlation with the number of cluster per square meter at 5% probability level. Moreover, despite the fact that the rates of fertilizers used are statistically in the same level, but using 60 kg NITROGEN per hectare is recommended. Plant residues management method did not have any significant effect on the yield of RATOON grain.
