Abstract:   (204 Views)
Golestan province is one of the major regions of wheat production in the country. Azospirillum brasilense، an Azotobacter، acted as resolvent of phosphate and a microorganisms for fixing molecular nitrogen for cooperating with other root crops and grasses in enhancing their growth and development. To investigate the effects of rhizobacteria on yield and yield components of wheat a  factorial experiment based on a randomized complete block design with three replications was conducted in Gonbad Kavous region. The treatments included of two wheat cultivars (Morvarid and Gonbad) and five levels of Bactria: control (no bacteria), Azotobacter, Azospirillum, resolvent phosphate and mixe of these three bacteria. Analysis of variance showed that the interaction of cultivar and bacterial characteristics of leaves, leaf dry weight, spike length, grain weight and grain yield in irrigated conditions and length of awn and grain yield in rainfed conditions was significant. Gonbad cultivar had the highest grain yield (2358.36 kg ha-1) in treatment of mixed three bacteria.
