Determination of the Botanical Composition of the Arid Pasture in District Eğil, Diyarbakır

This research was conducted to determine vegetation structures of the native pastures in the five villages of district Eğil, Diyarbakır. Vegetations of the pastures were studied by the Loop Method. In each pasture 400 loop measurements in 4 lines were made. Plant-covered area rate, botanical composition in the plant covered area was calculated from the loop measurements. In the research, 35 plant species from 27 different genera of 10 plant families were obtained. As depending on the pastures, plant cover percentages varied between 26.60% to 60.36% and botanical composition rate of grasses, legumes and other family plants in the total plant cover varied between 27.81%, and 37.45%, 8.67%, and 39.31%, 23.24%, and 59.16%, respectively. The investigation, it was concluded that vegetations of the pastures were all composed of invader plants

Research on the Vegetation Structure of the Pastures in Silvan District, Diyarbakır

This research was conducted to determine the vegetation structures of the native pastures in the six villages of district Silvan, Diyarbakır, in the year of 2014 .Vegetations of the pastures were studied by the Loop Method. In each pasture 400 loop measurements in 4 lines were made. Plant-covered area rate, botanical composition in the plant covered area was calculated from the loop measurements. 43 plant species of 35 genus from 11 families were determined on the vegetation of the pastures. Plant cover percentages varied between 46.2% to 72.0% and botanical composition rate of grasses, legumes and other family plants in the total plant cover varied between 30.81%, and 72.92%, 16.89%, and 48.25%, 10.19%, and 39.74%, respectively, as depending on the pastures. From the results of the research, it was concluded that vegetations of the pastures were generally composed of invader plants. Therefore the pastures have poor condition. The research on the determination of proper improvement methods for the pastures must be conducted

The effect of different replications of humic acid fertilization on yield performances of common vetch (Vicia sativa L.)

This study was conducted in a randomized complete block design with three replications in Diyarbakir, Turkey, in 2003 to 2004 and 2004 to 2005 growing seasons, in order to determine the effects of different humic acid treatments (control, soil 100%, seeds 100%, leaves 100%, soil 50% + seeds 50%, soil 50% + leaves 50%, seeds 50% + leaves 50% and seeds 33% + soil 33% + leaves 33% fertilizations) on herbage and crude protein concentration of common vetch. According to the results of this study, humic acid treatments increased the yields, and this increase was found to be significant as well as statistical. According to the two-year research, the highest value for green herbage yield (15180 kg ha-1), dry herbage yield (3045 kg ha-1) and plant height (61 cm) was obtained from soil 100% fertilizations, while the highest crude protein concentration (13.43%) was obtained from seeds 33% + soil 33% + leaves 33% fertilizations
