Determination of Hay Yield, Quality and Botanical Composition of Different Rangeland Sites under Continental Climate Zo

Abstract

This research was carried out on different rangeland sections of Kırkgeçit village of Gürpınar district in Van province to determine the botanical composition, hay yield and the quality of rangeland in 2015. Measurements of rangeland vegetation in the study were conducted in 3 different sections including northern, southern and western aspects between 23rd and 24th of June 2015. According to results of the research; the highest green herbage and hay herbage yields were determined at the southern part of the rangeland with 879.2 kg da-1 and 278.1 kg da-1, respectively. The proportion of botanical composition was, 62.46% grasses, 7.61% legumes and 29.93% other plant families, according to the weight for the entire rangeland. The highest percentage (71.82%) of grasses was found on western aspect, the highest percentage (20.32%) of legumes was found on south aspect, and there were no difference on the distribution of other plant families. In the vegetation survey conducted in the studied rangeland, 60 different plant taxa from 43 different genus belonging to 16 different plant families were detected. Depending on the aspects, The crude protein ratio, acid detergent fibre ratio, neutral detergent fibre ratio, crude protein yield and relative feed value of obtained hay were determined as 14.30-16.48%, 34.66- 37.59%, 53.15-60.64%, 28.36-42.78 kg da-1 and 92.7-107.2, respectively. According to relative feed value, roughage obtained from rangeland was determined as “medium” and “good qualified”.
