Efficiency of dual inoculation by Glomus mosseae and Azotobacter chroococcum on growth, productivity of some wheat)Triticum aestivum L.( recombinations

Abstract

This investigation was conducted to determine the response of 24 genetic recombination of wheat crop to bioinoculation with mixture of Glomus mosseae (Nicolson&Trappe.) Gerd&Trappe 250 spores/gram soil and 10ml (107cfu/ml) of Azotobacter chroococcum /0.5meter seeded line. Treatments were distributed in randomly block design with three replicates on 2010-2011growing season. Growth parameters: Percentage of germination, flowering after 106 days of germination, Maturity after 130 days of cultivation, Number of branches after 126 days of cultivation, dry weight of vegetative growth, number of spikes in the line, number of grains per spike, average weight of 1000 grain, and total weight of seeds in the line were taken. Results revealed different response of the tested recombinations for biofertilizers effects.The recombination wahat al Iraq, Babil, M707, Mexipaq, Furat, Dijla, Um-rabee, Tamose2, Tamose3, Ure, M619B, M613, M606, M615A, M630, M621, and Noor reveald significant increasing differences in most growth and productivity parameters specialy Wahat al Iraq, M707, Mexipaq, M613 which recorded yield increament at 96,89,59,57% respectively,while the recombination Tellaafar3, Adnaaia, Medaaen , M612, M633A, M615B, M633B showed negative response and recorded reduction percentages 10,15 ,4 ,12 ,9,45,24% as comparison with control respectively.
