A field experiment was performed during the spring season of 2016, in the Field Crops Field Experiment, Faculty of Agriculture, University of Anbar (Abu Ghraib location), located at longitude line 44.24° east and latitude 33.22° north at 34.1m above the sea level. To study the effect of three Cultivars of sorghum (Enkath, Rabeh and Giza113) and forth Humiforte 0, 3, 5 and 7 L ha-1 in some traits of growth, yield and quality, the experiment ,was Applied by using split–plots Design according to (R.C.B.D) with three replicates. The main plot included bio concentration and cultivars as sub-plots.
The results showed that Giza 113 was superior to the height of the plant and the weight of 500 grains and the percentage of protein and the lowest mean of number of days from planting to 75 % flowering. While the highest yield of the total grain yield, 6.99 ton ha-1 was given to the Enkath cultivar. Rabeh was superior in leaf area, chlorophyll content and number of grains in the head. The spraying with Humiforte improved the growth, yield and quality characteristics and gave the highest 7 L ha-1 concentration of plant height, number of head grains, grain weight, total grain yield 7.21 tons ha-1and protein ratio and the lowest mean of number of days from planting to 75 % flowering. Spraying at 5 L ha-1 Give the highest average leaf area and chlorophyll content in leaves. Interaction between cultivars and biomass concentrations had a significant effect on the traits of plant height and total grain yield, with the cultivar record saving at 7 l ha-1the highest average yield of grain 7.86 tons ha–1.
