Under Chemical,Organic, and Biological Nitrogen Fertilizers TT - ارزیابی برخی صفات فیزیولوژیک و کیفی اکوتیپ های مختلف بزرک(usitatissimum L. Linum) در پاسخ به کودهای شیمیایی، آلی و زیستی نیتروژن N2 - Nitrogen is one of the major macronutrients in cropping systems. Considering the effect of nitrogen on the quantitative and qualitative characteristics of linseed, a field experiment was conducted as factorial arrangement in a randomized complete block design with three replications in the Research Station of Faculty of Agriculture, Shahrekord University in 2012. Five fertilizer treatments of urea, Azomin, Nitroxin, Super NitroPlus and control (without fertilizer) and three ecotypes of Iranian, Canadian and French linseed in this experiment were examined. Harvest index, seed protein and oil contents (%) were evaluated. Meanwhile, the trend of the cumulative crop growth rate (CGR) and fitted regression model was studied. Harvest index was significantly different between ecotypes. Harvest index, seed protein and oil contents showed significant responses to fertilizer treatments. The interaction between ecotypes and fertilizer treatments was significant for harvest index and seed oil content. Non-linear regression model (peak) best fitted on the trend of crop growth rate (CGR) in different ecotypes and different fertilizer treatments. According to result, it seems biological fertilizer of Super NitroPlus, Nitroxin and organic fertilizer of Azomin are capable of being hired in sustainable agriculture as an alternative to chemical fertilizers in linseed cultivation.
