Abstract

In order to study the Effects of different levels of NITROGEN and plant density on oil yield and its components of CASTOR, this experiment was conducted at Agronomy Jihad field of Qazvin in 2006. Field experiment was carried out by a split plot design with 4 replications. The factors which studied were NITROGEN levels 0, 40, 80 and 120 kg ha-1 and plant density with 2.5, 4 and 5.5 plant m-2. The results showed that NITROGEN significant effect on seed yield, oil yield and lateral stem (a=1%), seed thousand weight (a=5%) and oil percent was not significantly affected due to NITROGEN. Comparison showed that highest seed yield and oil yield were achieved under application of 80 kg ha-1 NITROGEN, highest seed thousand weight under 120 kg ha-1 NITROGEN and highest lateral stem under 40 kg ha-1 NITROGEN. Also plant density significant effect on seed yield, oil yield and lateral stem (a=1%), seed thousand weight (a=5%) and oil percent was not significantly affected due to plant density. Comparison showed that highest seed yield and oil yield were achieved under 5.5 plant m-2, highest seed thousand weight under 4 plant m-2 and highest lateral stem under 2.5 plant m-2. Interaction of NITROGEN and plant density significant effect on oil yield and lateral stem (a=1%), seed yield (a=5%) and other characteristics were not significantly affected due interaction of NITROGEN and plant density. The results of this experiment showed that were affected NITROGEN and plant density on oil yield and its component sorely that is gist for received to oil yield maximum of CASTOR.
