Research ArticleOpen accessPhrase in the titleMonitoring Growing Season Length of Deciduous Broad Leaf Forest Derived From Satellite Data in IranSasan Babaei Kafaki, Asadollah Mataji, Seyed Armin HashemiProblem statement: Leaf phenology describes the seasonal cycle of leaf functioning and is essential for understanding the interactions between the biosphere, the climate and biogeochemical cycles. This study aimed to quantify changes in plant phenology of deciduous broadleaf forests between the years 1982-1999 and investigate the relationships between the onset dates of phenology and climatic factors. Approach: We studied the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,557 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEvaluation of the Genetic Material of the Grass Pea (Lathyrus Sativus L.) Seed Collection in Northern KazakhstanArysgul Turbekova, Irina Oshergina, Alzhan Kurmangozhinov et al.One of the main agriculture fields in the Republic of Kazakhstan is the diversification of crop production based on the preservation of soil fertility and minimal cultivation technologies. Ensuring sustainable grain production of legumes will significantly increase and strengthen the role of grain production in the country's economy, will allow significant amounts of land resources to be involved in agricultural … …OnLine Journal of Biological Sciences, Vol. 22, Issue 2 · 14 Apr 2022 · 6,162 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of Organic Ameliorants on Grey Soil FertilityAsanbay Tagaev, Amandyk Kostakov, Sabir MakhmadzhanovThe study aimed to assess the effectiveness of organic-biological ameliorants for restoring the fertility of light grey soils in the Turkestan region of Kazakhstan, which are characterised by low humus content (0.8-1.1%) and high alkalinity (pH 7.9-8.3). The field experiment was conducted on an area of 2304 m2 using four treatment options: control (variant 1 only mineral fertilisers) and three … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 15 Sep 2026 · 693 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntroduction of the Pasture Plant Fescue (Festuca valesiaca) for the Improvement of Degraded Pastures in the Steppe Zone of KazakhstanMeldebekova Nurgul Alikhanovna, Seitbattalova Ainur Islamovna, Ainebekova Bakyt Alpysbaevna et al.This study presents the results of a comprehensive evaluation of Festuca valesiaca, a dominant perennial grass species widely used in steppe ecosystems for pasture improvement. Previous research has demonstrated the importance of native fescue species in enhancing productivity and resilience of degraded rangelands under arid conditions. However, breeding efforts for this species in Kazakhstan remain insufficiently developed. The research was … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 14 Sep 2026 · 662 accessesView PDF Cite

Research ArticleOpen accessIn the abstractClimate-Driven Productivity Responses and Implications for Genetic Adaptation and Breeding of Boreal Trees in KazakhstanZhadyra Baigazakova, Kuralay Mazarzhanova, Asset Satayev et al.Kazakhstan’s boreal and forest-steppe forests form the southern ecotonal edge of the West Siberian taiga, where relatively small changes in heat and moisture can trigger disproportionate impacts on tree growth, mortality, and regeneration. Although forests cover only ~4% of Kazakhstan, they provide critical ecosystem services: stabilizing hydrological regimes, buffering microclimates, protecting agricultural lands from wind and water erosion, and supporting … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 10 Aug 2026 · 709 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHydrophysical Properties of Soils as Indicators of the Hydrological Role of Rudny Altai ForestsAndrey Kalachev, Tamara Burenina, Stanislav Rogovsky et al.The hydrophysical properties of soils and parent rock are key factors shaping forest hydrological functioning, as they influence multiple runoff components. This study assessed the effects of forest stand composition on soil moisture and water permeability between 2021 and 2023 in the middle mountain-taiga zone of the Rudny Altai, within the Zhuravlikha River basin, a tributary of the Irtysh River. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 24 Mar 2026 · 1,316 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMarket Analysis and Evaluation of the Nutritional Quality of Fodder Grown in Urban and Peri-Urban Areas of Niamey, NigerSalou Issaka Seybou, Fernàndez Rebollo Pilar, José Ramon Leal Murillo et al.The development of domestic ruminant livestock farming is hampered by the lack of forage, which is largely dependent on natural pastures and crop residues. In the outskirts of major cities, access to grazing land is becoming increasingly restricted. To meet the growing demand for fodder, feed markets are emerging in urban centers. The main aim of this one-year, three-season study … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 7 Nov 2025 · 2,135 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhancing the Effectiveness of Feed Production in Arid Areas, Northern Kazakhstan, Considering the Utilization of Soil Moisture ResourcesKudaybergen Konopianov, Irina Anikina, Karina Omarova et al.The problems of sustainability of crop production in arid regions are actual. Moreover, often the aridity factor is combined with other stress factors, such as elevated temperatures and soil salinity. The article evaluates the effectiveness of the use of moisture and heat resources when growing fodder crops in arid conditions with a short growing season. In order to compare the … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 24 May 2024 · 4,885 accessesView PDF Cite
