Effect of different levels of nitrogen and potassium on yield, yield components and oil content of sunflower
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 2
Abstract
To study the effect of different doses of nitrogen and potassium on yield and yield components of sunflower in Sistan region was carried out an experiment as split plot based on randomized complete block with three replications in Agricultural Research Station of Zahak at spring of 2012. Experimental treatments was included from four levels of nitrogen: 0, 75, 150 and 225 kg/ha as main factor, and three levels of potassium: 0, 100 and 150 kg/ha as sub factor. The results of variance analysis showed that the amounts of nitrogen and potassium fertilizers had significant effect on plant height, biological yield, seed yield and seed oil content. The highest amounts of all measured factors obtained from treatment of 225 kg/ha nitrogen and 150 kg/ha potassium. Generally results indicate that use of nitrogen and potassium fertilizers improves quantitative and qualitative characteristics of sunflower.
