Abstract
To determine the effect of organic fertilizer on durum wheat (Ovanto), an experiment was conducted during two consequent growing seasons of 2012- 2013 and 2013-2014. The experiment was performed in Qlyasan Agriculture Research Station, College of Agricultural Sciences- University of Sulaimani, using RCBD design with three replications. Organic fertilizer of the contents: Ec 0.19 ds. m-1, N 2%, P 2.5%, K 2.1%, O. M 60%, moisture 40% and P. H 7.5% was used at four levels of 0, 4, 8 and 12) Ton/Ha. Growth characters of the grown wheat were measured and the averages of both seasons were analyzed. The results indicated the significant effect of organic Fertilizers on the studied characteristics such as root depth (cm), plant height (cm), No. of leaves/plant, leaf dry weight (g), total dry weight (g), stem weight % and leaves weight %. While non- significant effect was recorded for the characteristics of number of tillers/plant, root dry weight (g), stem dry weight (g) and root weight, maximum values referred to the last treatment level (12 Ton/Ha) for the characteristics of plant height (cm), leaf dry weight (g) and total dry weight (g), four-Ton/Ha exhibited the maximum leaf %. While the maximum values recorded for the fertilization level of 8 were for the characters; root depth (cm); however, control level was produced the maximum values for the characteristics; No. of leaves/plant and stem %.
