Abstract
Two successive field experiments were conducted in El-matarya District (31° 16′ n, 32° 12′ e) which located near of Manzala lake, Dakhalia Governorate during the winter season of (2009-2010) and (2010-2011) to study the integrated impacts of halotolerant n2 fixers and humic acid application on N – availability and nutrient contents of wheat crop (Triticum Aestivum L). CV Sakha 93 in salt affected soils.
18 treatments were arranged in a split-split block design, which were the simple possible combination between two treatments of humic acid (with (50 L fed-1. & without) as the main plots, three rates of bio inoculation (Non-inoculation, Azotobacter + Azospirillum and Nostoc + Anabaena) as the sub plots and three levels of nitrogen fertilization (control, 50 and 100% of the recommended dose) as sub- sub plots. Each treatment was replicated three times. Thus, the total number of plots used for each season was 54 plots.
CONCLUSION
It could be concluded that inoculation of wheat plant with the mixture of multi strains inoculants (Azotobacter + Azospirillum) combined with humic acid (50 L fed-1) under N-fertilization at rate of 50% from recommended doses are considered as the most suitable treatment for realizing the highest economic yield and the best quality treatments for wheat plants.
