A Comparison of Various Ecological Indexes for Environmental Assessment of Vulnerable Mountain Ecosystems

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Gülbübü KURMANBEKOVA | Ciyde TOKPAEVA

The aim of this work was to compare various ecological indexes to assess the state of urbanized ecosystems of the Issyk-Kul region in the Kyrgyz Republic. Soil samples were analyzed for Pb, Zn, Fe, Cu and Cd using AAS. Heavy metal contamination status was assessed using indexes for enrichment factor, geo accumulation, contamination factor, degree of contamination, pollution load, potential ecological risk and integrated risk using the Triad approach. Results show marked variations of heavy metal concentrations within the study area. The concentrations of heavy metals in soils of Issyk-Kul had ...Более

Agronomic Performance of Spring Barley Cultivars under Different Eco-Environmental Conditions

Bircan USUBALİYEV | Gülbübü KURMANBEKOVA | Kadırbay ÇEKİROV | Nurzat TOTUBAYEVA

In this study, five agronomic traits of 29 barley accessions were evaluated in different agro-environmental conditions. Accessions represented cultivars from Kyrgyzstan, Ukraine, and the Nordic and Baltic countries as well as landraces from northeastern and eastern Russia. The field experiments were carried out in two countries (Latvia and Kyrgyzstan) in order to select the suitable genotypes or cultivars as a source for Kyrgyz barley breeding programs. Among the accessions studied, we found material that can be used in Kyrgyz breeding as potential sources of earliness, spike length and TKW. A ...Более
