اثر کود بیولوژیک نیتروکسین بر عملکرد و اجزاء عملکرد گندم (رقم شیرودی) آلوده به فوزاریوم سنبله

Fusarium head blight, is one of the important diseases of wheat and small grains creals, which leads to loss of yield and seed quality. In order to investigate effect of the nitroxin biological fertilizer on yield and yield components of wheat (Shirudi figure) infected fusarium head blight, greenhouse expriment in Zabol University in the fall of 92 as a completely randomized design with four replications. Measured traits that was investigated include:spike length, shoot dry weight, root dry weight, seed yield, biological yield, 100 seed weight and seed number. The results of this project showed that the effects of Nitroxin biological fertilizer on all measured traits except for shoot dry weight, biological yield and 100 seed weight were significant. In traits of spike length, root dry weight, number of seed effectiveness of control treatment (no fertilizer application) was increased greater than the Nitroxin fertilizer. Only,in seed yield traits, the amount of Nitroxin manure increased by 27% compared to control. The results showed that nitroxin fertilizer on seed yield in wheat (Shirudi figure) was effective which can be due to effective symbiotic Azospirillum and Azotobacter bacteria in nutrient uptake and transfer to plant shoot to form seed.
