Research ArticleOpen accessIn the abstractThe Study of Seasonal Patterns in Vegetation Diversity and Forage Yield DynamicsSema, Jasmal Ahmari Syamsu et al.This study examines the seasonal dynamics of vegetation diversity, forage yield, and nutrient quality in Tarabbi Village, Malili District, East Luwu Regency, conducted from July 2023 to July 2024. Using a survey approach and field measurements, data were collected through the Estimated Actual Weight method and Summed Dominance Ratio (SDR), complemented by Geographic Information System (GIS) technology for analysis. Principal … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 7 Jul 2025 · 3,288 accessesView PDFCite
Research ArticleOpen accessIn the abstractRotational Pasture Management for Ameliorating Productivity and Feed Value of Vegetation, Soil Quality, and Sustainability in Dry Steppe ZoneGani Stybayev, Meisam Zargar, Beibit Nasiyev et al.Over the past years, a farming system in the Akmola region of Kazakhstan has undergone significant changes: The average number of animals per farm and the use of external inputs have significantly enhanced while the diversity of farming practices has decreased, becoming similar to intensive farming. In this research, we evaluated the rotational pastures for increasing the productivity and feed … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 18 Jan 2025 · 4,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Saving with Combined Irrigation MethodsAlexander Kalashnikov, Nurlan Balgabaev, Vyacheslav Zharkov et al.In the conditions of arid zones of irrigated agriculture, during the cultivation of horticultural and other crops, high air temperatures (over 25-30оС) and low relative humidity (less than 20-30%) are observed during the vegetation period of plants. In these circumstances, the combined irrigation method using drip irrigation and sprinkling allows optimizing the use of water during drip irrigation at air … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 6 Oct 2022 · 5,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining Causes of Gully Erosion and Associated Rates of Change in South-East Nigeria, using a Remote Sensing and GIS MethodologySylvanus IroThe study of gully development on a regional scale is currently threatened by the intrinsic costs associated with steady field tracking and monitoring and the lack of historic measurements to perform time series analysis. The research objective is to develop a low-cost GIS and Remote Sensing methodology for monitoring and quantifying gully erosion and development over time, identifying the impact … …American Journal of Environmental Sciences, Vol. 16, Issue 5 · 22 Oct 2020 · 7,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand-Cover Removal and Gully Development in Southeast Nigeria: A 30-Year Analysis with Pixel and OBIA Approaches in JuxtapositionSylvanus IroIn this study a study of gully erosion in southeast Nigeria is presented. The study of gully development on a regional scale is currently undermined by the inherent costs associated with consistent field monitoring and the lack of historic measurements to perform time series analysis. As a result, there are very few studies which implement long term analyses of gullies … …American Journal of Environmental Sciences, Vol. 16, Issue 2 · 9 Jun 2020 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Winter Hardiness Formation in Winter Wheat PlantsDaria Blyshchyk, Anatoliy Polevoy, Pavel FeoktistovA dynamic model, which describes the growth processes, plant development and the passing of the two phases of the autumn hardening under the influence of agrometeorological conditions in autumn, was developed. The model illustrates effects of intensity of Photosynthetically Active Radiation (PAR), sunlight levels, air temperature and soil moisture on the increment of reserves of photosynthesis products and soluble carbohydrates … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 9 Mar 2020 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Remote Sensing Techniques in Determining the Risk Taking Level of Different Seasons on Fire Generation in Terms of NDVI Index During the Year Case Study: Golestan Province, IranAkram Karimi, Sara Abdollahi, Kaveh Ostad-Ali-Askari et al.Knowledge of the nature of seasons and months in terms of the fire risk is very important in environmental planning, land management and forest resource management in order to achieve the sustainable development. One of the applications of remote sensing in this regard is the continuous monitoring of the zone to detect changes. Currently, the vegetation mapping is used to … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 30 Mar 2018 · 7,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Remote Sensing Techniques in Detecting and Predicting Forest Vegetation Change Using MODIS Satellite Data, Golestan, IranAkram Karimi, Sara Abdollahi, Hamid Reza Kabiri Balajadeh et al.It is so important to be aware of quantitative and qualitative characteristics of changes for the environment, land use planning and sustainable development. Detecting the changes in the condition of an issue is done by time difference observations. Change detection refers to the process of detecting time changes of an object through different time observations. The detection of changes by … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 30 Mar 2018 · 8,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractPasture Productivity Depending on the Method of Pasture use in the Steppe Zone of Northern KazakhstanBalzhan Akhylbekova, Nurlan Serekpayev, Adilbek Nogayev, Bakhytbek ZhumabekUnsystematic grazing of animals and continuous use of pastures leads to their degradation and, accordingly, to a shortage of pasture forage for the production of competitive environmentally friendly livestock products. The proportion of productive grasses in grass covers is decreasing; therefore, there is an urgent need to preserve valuable plant species in pasture grass, restore the productivity of natural vegetation … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 3 Nov 2022 · 5,909 accessesView PDFCite
