The area and rubber production in 2020 was 3,316,047 ha with a productivity of 1,022 kg/ha. The low productivity is caused use of seedling materials. Adaptation testing is one of the stages for selecting superior rubber clones in various environmental conditions, the influencing factors are clone or … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 22 Mar 2024 · 5,300 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Varietal Characteristics and Planting Schemes of Remontant Raspberries on their ProductivityLyazzat Zhailibayeva, Sergey Oleichenko, Yerlan Dutbayev et al.The red raspberry (Rubus idaeus L.) is a member of the Rosaceae family. The production of raspberries has increased rapidly worldwide. In recent years, about 300 ha of remontant raspberry varieties have been planted in the Almaty region, Kazakhstan. These varieties are technologically easier to grow compared to traditional varieties because they bear fruit on annual shoots and do not … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 29 Dec 2023 · 5,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of a Methodology for Determining the Nutritional Value of Pasture Feed Considering the Fractions of Easily Digestible Carbohydrates in the Desert Zone of Southern KazakhstanAmanbay Karynbayev, Beybit Nasiyev, Kuzembayuly Zharylkasyn et al.Due to the absence of easily digestible carbohydrates (sugar and starch, which are of great importance in animal nutrition) in the existing methods of assessing the nutritional value of feed, the need to include them in the methods for improving the overall nutritional value is a particularly urgent matter in feed manufacture for desert livestock industries. The study was carried … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 4 Sep 2023 · 4,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractSMEs Strategies to Improve the Competitiveness of Dairy Products in West Sumatra Province, IndonesiaRahmi Wati, Firwan Tan, Donard Games, Endrizal RidwanConsidered a side business, most dairy farms in Indonesia are small-scale farms with low productivity. Farmers tend to sell the milk produced in the form of fresh milk rather than processed products. This condition causes low competitiveness of dairy products and the difficulty of dairy products penetrating the modern market. This study aims to identify factors that determine competitiveness and … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 2 · 28 Jun 2023 · 5,980 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 abstractPoly-Species Phytocenoses for Ecosystem Restoration of Degraded Soil CoversAlmabek B. Nugmanov, Sergey V. Mamikhin, Khusain Kh. Valiev et al.Agroecological studies are based on the concept that, by understanding ecological processes, it is possible to manage agroecosystems for more sustainable production of more biomass and, thus, protection of natural resources. Many studies in the field of agroecology show that some farming methods can improve soil quality and restore agroecosystems by increasing plant biodiversity. Functional characteristics of plants for the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 22 Jul 2022 · 5,713 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrincipal Component Analysis of the Female Pengging Soloan Duck Based on Morphometric TraitsRini Nur Hayati, Subiharta, Yudi Adinata et al.The Pengging Soloan duck is an emerging indigenous genetic resource from Central Java, Indonesia, recognized for its adaptability and egg-laying potential. However, its phenotypic characterization remains limited compared with established Indonesian duck breeds such as Mojosari, Tegal, and Magelang ducks. This study aimed to characterize 70 adult female Pengging Soloan ducks aged 5 6.5 months using Principal Component Analysis (PCA) … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 10 Sep 2026 · 940 accessesView PDFCite
