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 abstractIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction. Several previous studies reported that pendimethalin effectively duplicates the chromosome numbers of various plant species. The aim … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 22 Aug 2026 · 854 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

Research ArticleOpen accessIn the abstractAn Integrated Machine Learning Framework for Citrus Grading and Yield Prediction Using Classifier-Informed RegressionLydia Dede Obeng, Isaac O. OsunmakindeAgriculture remains a cornerstone of human sustenance, yet accurate citrus fruit grading and yield predictions remain significant challenges due to visual similarities between varieties such as oranges and grapefruits. This includes the inefficiencies of manual grading. This study presents a new dual-function machine learning system that integrates classification and regression to simultaneously grade citrus fruits and forecast crop yields. This … …Journal of Computer Science, Vol. 22, Issue 4 · 24 Apr 2026 · 1,891 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy on the Polyploidy Induction of Herbicides on Hengshan Astragalus MembranaceusJianxia Liu, Yanmao Gao, Lizhen Liu et al.Studying medicinal polyploid plants is of great significance for the cultivation of traditional Chinese medicine varieties and the extraction of active ingredients. The polyploidization of A. membranaceus (Astragalus membranaceus) was induced using two treatment methods: oryzalin and pendimethalin as mutagens. The results showed that in the same method, the induction effect of polyploidy was affected by the concentration of reagents … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 14 Apr 2026 · 1,535 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCluster and Correlation Analysis of Valuable Traits of Bean Cultivars Under Irrigation Conditions in KazakhstanKudaibergenov Mukhtar Sarsenbekovich, Bastaubaeva Sholpan Orazovna, Kanatkyzy Makpal et al.This study aimed to investigate a diverse collection of beans accessions under irrigation conditions in the Almaty region of Kazakhstan to identify promising genotypes for breeding. Over a ten-year period (2014–2024), 300 accessions were analyzed, of which 100 were selected for detailed assessment based on key agronomic traits including earliness, productivity, seed weight, disease resistance, protein content, and adaptability to … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 25 Mar 2026 · 1,378 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic and Environmental Interactions in Spring Wheat Resistance to Bipolaris Sorokiniana Root Rot in KazakhstanYerlan Dutbayev, Ardak Bolatbekova, Aidana Kharipzhanova et al.Common root rot caused by Bipolaris sorokiniana represents a major constraint to wheat production in Kazakhstan. This study evaluated the resistance of 30 spring bread and durum wheat genotypes under diverse environmental and treatment conditions in two contrasting regions (Almaty and Aktobe) during 2024. The experimental design included three treatment regimes: fungicide application, artificial inoculation with the pathogen, and natural … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 7 Mar 2026 · 1,517 accessesView PDF Cite
