تأثیر استفاده از باکتری نیتراژن بر تولید ژنوتیپ های امیدبخش گندم دیم در منطقه اردبیل

Abstract
To evaluate the effect of nitrogen bacterium on five dryland promising lines of wheat yield a factorial experiment based on a randomized complete block design with four replications and 20 treatments were performed in 2011 in Ardabil. Treatments consisted of five genotypes (C-86-2, C-86-3, C-86-4, C-86-7 and C-86-9) and Four levels of seed inoculation with nitrogen bacterium contains N0: control (without seeds coated with nitrogen bacterium and nitrogen fertilizer), N1: seeds coated as factory recommended, N2: seeds coated with doubled recommendations and N3: - farmer and nitrogen bacterium integrated treatment (twice the recommended seeds coated plants + % 50 farmers used urea in the spring). In the crop growth stages record the number of tillers, plant height, grain yield, grain weight and grain. Analysis of variance showed that the main effect of study cultivars and nitrogen bacterium was significant on most of the traits studied Interaction between varieties and seed surfaces coated with nitrogen bacterium showed that grain yield was significantly affected by treatments. Applying the control treatments (N0) lowest and seeds coated with double recommendations nitrogen bacterium had the highest grain yield difference was more than 500 kg per hectare. Results showed that genotype of C-86-2 and C-86-4 with integrated treatment (N3) was higher yield and maximum production.
