InvestigationOpen accessIn the keywordsDeveloping a System of Organic Farming Technologies to Obtain Environmentally Clean Agricultural Products (Organic Food) in the Steppe Zone of the Kostanai RegionAlmabek Batyrzhanovich Nugmanov, Yuriy Valerievich Tulayev, Saniya Abiltaevna Tulkubayeva, Svetlana Vladimirovna SomovaThe goal of the research is to study the opportunity to produce environmentally clean agricultural products (organic food) under the conditions of the Kostanai Region. The researches were made in two crop rotations: cereal laying fallow, two-field crop rotation (1 – biologized fallow – mustard, 2 – wheat) and cereal laying fallow, two-field crop rotation (1 – biologized fallow – … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 23 Dec 2017 · 7,391 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInfluence of Seeding Rate on Weed Density in Soybean Planting System for Southeastern Coastal PlainsPawel Wiatrak, Guihua ChenProblem statement: Increasing seeding rates may help decrease weed pressure in soybean [Glycine max (L.) Merr.] wide row spacing. Approach: The objective of this study was to evaluate the influence of five glyphosate-resistant soybean Maturity Groups (MG) (IV, V, VI, VII and VIII) and six seeding rates (68,000,136,000, 204,000, 272,000, 340,000 and 408,000 seeds ha-1) on weed density under dryland … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 25 Mar 2011 · 7,944 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntegrated Management and Fungicide Efficacy of Foliar Diseases in Spring Wheat in KazakhstanNadira Sultanova, Yerlan Dutbayev, Gulzada Abisheva et al.Spring wheat (Triticum aestivum L.) is a key economic crop in Kazakhstan. This study aimed to identify genetic sources conferring resistance to major foliar diseases and to quantify the contribution of fungicide application to yield stability. Field experiments conducted in 2024 assessed the resistance of 36 spring wheat genotypes, 17 common wheat and 19 durum wheat (T. durum Desf.), to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 17 Jul 2026 · 961 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDF Cite
