Abstract

In order to determine the appropriate amounts of POTASSIUM and NITROGEN fertilizers to achieve high grain and oil yields of rapeseed (Hyola 401) in paddy fields, a field experiment was conducted at Rice Research Institute of Iran (Rasht) in a factorial experiment based on the complete randomized block design with 3 replications in 2008-2010. The first factor was the amounts of POTASSIUM fertilizer in three levels (100, 150 and 200 kg.ha-1) and the second factor was NITROGEN fertilizer values in the four levels (zero, 180, 240 and 300 kg.ha-1 from urea resource). The results of the combined analysis of variance showed that significant difference between POTASSIUM levels, according as application of 150 and 200 kg.ha-1 POTASSIUM had the highest of GRAIN YIELD. Between the levels of NITROGEN, application of 240 and 300 kg.ha-1 produced the highest GRAIN YIELD. The control treatment with average of 43.92%, showed the maximum oil precent. In general, 150 kg.ha-1 of POTASSIUM and 240 kg.ha-1 NITROGEN level are recomended due to less fertilizer consumption and prevention of destroying effect on the environment.
