بررسی تأثیر کودهای زیستی بر خصوصیات کمی و کیفی لاین‌های مختلف بزرک (Linum usitatissimum L.)

In order to investigate the effect of bio-fertilizers on the yield and yield components of flax lines, a study was conducted during 2010 growing season at the Agricultural Research Station of Saatlo in Urmia. A split plot design based on randomized complete blocks with four replications was performed in this study. Main factor (a) consisted of fertilizer application form (a1 = control without nitrogen fertilizer, a2 = nitrogen fertilizer, a3 = nitroxin + N, a4 = phosphate barvar 2 + N, and a5 = nitroxin + phosphate barvar 2 + N) and sub factor (b) consisted of five lines of oily flax (b1 = 97-26, b2 = 97-14, b3 = 97-3, b4 = 97-21, b5 = 97-19). Quantitative and qualitative traits such as number of sub stems, leaf weight, capsule weight per main stem and sub stems, seed yield, oil and protein content were calculated or estimated. Results showed that the main factor (fertilizer form) had significant effect (at α=0.01 probability level) on all the parameters which have been studied in this experiment. Sub factor (linseed lines) and interaction between the two factors had statistically significant effects on all traits. The highest seed yield (4781 kg h-1) and the highest seed oil content (36.5%) were obtained from applying nitroxin + phosphateye barvare 2 + N on 97-14 and 97-3 lines. Results showed that using of Nitroxin and Phosphateye barvare 2 biofertilizers could be effective in increasing grain yield of linseed. Therefore, application of Nitroxin and Phosphateye barvare 2 biofertilizers could be used to improve soil physio-chemical properties and to increase quantitative and qualitative yield parameters of linseed.
