| Popis: | In order to determine the effect of different levels of sulfur bentonite on yield and yield components of canola a factorial experiment was conducted on the basis of randomized complete block design with three replications in Mashhad in 2009-2010 growing season. Factors included four levels of sulfur bentonite (0, 300, 400 and 500 kg.h-1) and two varieties of canola (Modena and Zarfam). The result showed that the increase in sulfur increased some vegetative traits such as leaf area index and plant height. Using sulfur caused increased pod number, seed weight, in addition of oil and protein content and seed yield. Grain yield increase was due to seed weight and LAI. Two varieties were different to responses the sulfur. While in no sulfur application there was no significant difference in seed yield, in 500 Kg sulfur application yield of Zarfam compared to Modena increased about 29.63. According to the results there are significant differences between cultivars in terms of response to the sulfur fertilizer. Therefore it is necessary to evaluate effect of sulfur application of canola productivity in different climate conditions of Iran. |
