Tarbiat Modares University (TMU) ECOPERSIA 2322-2700 10 1 2022 12 01 Effects of semi-circular bunds on plant vegetation and soil properties of Naroon and Neron rangelands- Sistan and Baloochestan 1 11 17332 EN Mahdieh Ebrahimi University of Zabol Journal Article 1970 01 01 <strong>Aim</strong>: In this paper, the semi–circular bund treatments were contrasted to address the following questions: how does semi-circular bund affect the vascular plants richness and diversity in Naroon and Neron rangelands of Sistan and Baloochestan? and do the soil properties responses to the semi–circular bund? <strong>Materials & Methods:</strong> Next to every site, a site was selected as controlled ones. Vegetation (production, vegetation cover, density, richness, diversity) and soil data (texture, pH, EC, organic carbon, total nitrogen, available phosphorus, available potassium, CaCO₃) were analyzed in completely randomized design.<br> <strong>Findings:</strong> In total, 11 species from 6 families and 8 genera were observed. Control treatment of Neron exhibited the highest number of plant species. Semi-circular bunds exhibited the highest vegetation cover, production and density. The highest and lowest species richness and diversity were measured in Naroon and Neron semi-circular bunds. Results showed that the amounts of organic carbon, nitrogen, potassium and phosphorus increased significantly in semi-circular bunds compared with the control areas. The highest organic carbon, nitrogen and potassium related to Neron semi-circular bund. Naroon and Neron semi-circular bunds had the highest amounts of clay and the least value was measured in the control treatments. <br> <strong>Conclusion</strong><strong>:</strong> In total, the results of study showed that semi-circular bund had positive effect on vegetation cover and soil properties in the rangelands of study area. https://ecopersia.modares.ac.ir/article_17332_2fbe1c703f6893c2bc5066fcbcaa2048.pdf
