Evaluation of Forage Crops Production and Quality of Two Different Rangelands in Sulaimani Governorate

Abstract

This study was conducted during 2015 in Sulaimani governorate at two main different locations of Sharbazher, Dukan, each one with some sub-locations, the sub- location of sharbazher that contains (Qalachwlan, Bnawela, Kana-Swra, Byana, Bazarw and Kane-Bewka) . The sub- location of Dukan that contains (Mergapan, Kwera-Kane, Hanaran, Qzlar and Kilka-Smaq) to estimate fresh yield, dry yield, dry matter and animal unit. The rangeland areas of Sulaimani governorate located between 350 10' – 360 27' N and 440 40' – 460 22' E were restricted, 250017 and658801 ha for Sharbazher and Dukan locations respectively. The most important results indicated that, it was noticed that the sub-location of Qalachwalan at sharbazher location gave the maximum values of plant height, stem dry weight, leaf dry weight and Leaf Stem ratio for both legumes and grasses with 27.22, 52.9 cm, 5.28% and1.80% as the means of nine replicates respectively. However, the sub-location of Mergapan at Dwkan location gave the maximum values of plant height with 40.43, 69.00cm for both legumes and grasses respectively.Dukan location gave the maximum value of total dry yield 970431.60 ton and 2940701.80 Animal unit/three months, while Sharbazher location which gave the minimum value total dry yield of 17216.20 ton and 52170.30 animal unit/3 months as the means of four replicates respectively. The highest fresh yield, dry yield and animal unit obtained Dukan, location which 13348.27 and 2554.85 kg/ha 2940701.80 animal unit respectively .Results of chemical analysis for the grass and legume plants showed that there were differences between locations. Dukan location gave the maximum percentage of protein content, Carbohydrate, fiber, and magnesium which were (8.75, 17.80 ,19.50 , and 0.74 %) respectively, for legume plants .However, chemical contents for grass plant showed that Sharbazher location gave the maximum percentage of carbohydrate, fiber, oil , phosphorous and ash contents which were (22.28 , 23.50 , 1.22 , 1.33 and 11.01 %), respectively.
