Research ArticleOpen accessIn the abstractOptimizing Lentil Breeding Models for South-East Kazakhstan: Yield, Adaptability, and Protein EnhancementSaikenova Alma Zhumabaevna, Kudaibergenov Mukhtar Sarsenbekovich, Kanatkyzy Makpal et al.This study presents the development of a model for optimizing lentil breeding in the agroclimatic conditions of southeastern Kazakhstan. By evaluating 31 lentil varieties and hybrid populations (F1, F2, and F3), key economically valuable traits such as yield, protein content, drought resistance, and adaptability to mechanized harvesting were identified. A systematic selection process enabled the creation of lentil variety models … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 24 Sep 2025 · 3,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Evaluation of a Pneumatic Prototype Machine Designed to Control the Colorado Potato Beetle in Potato CropsSaad Almady, Mohamed KhelifiThe Colorado Potato Beetle (CPB), Leptinotarsa decemlineata Say, 1824, is a major insect pest of potato plants. It can greatly reduce potato yields if left uncontrolled. The most effective method of controlling the CPB is to apply chemical insecticides during its life cycle. However, the CPB tends to develop resistance to chemicals. Therefore, its control is difficult. This has prompted … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 26 Dec 2022 · 6,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgronomic and Economic Parameter Estimates of Cocoyam as Influenced by Fertilizer and EnvironmentPrince Emmanuel Norman, Yvonne Sylvia Gloria Ethel Norman, Jenneh Fatima BebeleyThe effects of fertilizer and environment on agronomic traits and economic parameters in cocoyam were assessed at the Njala Agricultural Research Centre experimental site during the 2014/2015 and 2015/2016 cropping seasons. The fertilizer types used were 200 kg ha–1 NPK 15-15-15, 2000 kg ha–1 Rabbit Manure (RM), and no fertilizer (control). The trial was established in the open field and … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 24 Nov 2022 · 6,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevention of Desertification and Land Degradation using Black Saxaul in Arid ConditionsBirzhan Yessimbek, Bulkajyr Mambetov, Ruslan Akhmetov et al.The harsh climate of the arid zone determines several biological features in black saxaul plantations. Therefore, the study of the growth and condition of artificial plantations, depending on the use of physiologically active moisture-absorbing substances and growth biostimulants, is of particular practical importance. In the Moinkum sands of the Zhambyl region (Kazakhstan), observations of the growth and development of the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 22 Nov 2022 · 5,516 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
Research ArticleOpen accessIn the abstractSensitivity of Okra Growth Indices to Various Moisture ConditionsAkeem MakindeThis study evaluates the effects of flooding conditions on two Okra cultivars (Ibadan local and Jokoso) at Abeokuta, Nigeria. The flooding conditions vary from continuous Flooding (FLD), Wetting after three Days (W3D), Wetting after five Days (W5D), Wetting after seven Days (W7D), and Wetting after ten Days (W10D). The agronomic parameters (leaf width, leaf length, plant height, numbers of leaves, … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 4 Aug 2022 · 6,547 accessesView PDFCite
