Abstract

This research was carried out on a sandy loam soil during two consecutive seasons
of 2011/2012 and 2012/2013 in the Experimental Farm of the Faculty of Agriculture, South Valley
University at Qena, Egypt. The recommended N (mineral), FMC "Filter Mud Cake” and bio-fertilizer
(Azotobacter chroococcum and Azospirillum lipoferum) were applied alone and in various combinations
among them on two bread wheat cultivars (Triticum aestivum) Giza-168 and Sids-12 to study their
effects on total chlorophyll content, spike length, 1000-grain weight, grain, straw and biological
yields/fad., and protein percentage. The experiment was arranged in a split plot based on randomized
complete block design with four replications. The results showed that the application of Bio and FMC
in combination with nitrogen fertilization T11 (50% mineral N +50% N as FMC +N Bio) and T12 (25%
mineral N +75% N as FMC +N Bio) significantly increased all characters studied: i.e. Spike length,
1000-grain weight, grain, straw and biological yields (ton/fad.) in both seasons.
