    Abstract: Faidherbia albida (Del.) A. Chev. is a key agroforestry parklands species providing provisioning and regulating ecosystem services to people. Therefore, sustainable management and conservation of the species populations are great challenges on its distribution area. However, the species response to spatial variability of ecological conditions is po... Show More

    Abstract: The fertilizer requirement of tef varies from agro-ecology to agro-ecology and from soil to soil. Therefore, the objective of this study was to refine optimum phosphorus rate for tef under balanced fertilization. The experiment was conducted on-farm during main cropping season for two consecutive years (2015-2016) in Vertisol at Ada’a District. The... Show More

    Abstract: Worldwide there are greater than 4,100 species of PPNs. The most common opponent of agricultural production is PPNs. Plant parasitic nematodes (PPN) cause substantial economic destruction to an extensive range of crops. Nematicide Chemicals are considered the furthermost operative method in reducing nematodes population. Increasing concern over che... Show More

    Abstract: Wheat stem rust caused by Puccinia graminis f.sp tritici is constant biotic constraint of wheat production across the world. Because of quick alteration of genetic makeup of wheat stem rust pathogen; monitoring shift in virulence within pathogen is crucial to avoid sudden occurrence of epidemics due race change. This study was to identify physiolog... Show More

    Abstract: Silicon (Si) is used to alleviate abiotic stress in plants. Applying siliceous fertilizer in combination with regulated deficit irrigation may reduce water consumption during plant vegetative growth period. In this study, winter squash ‘East Elite’ was irrigated with 0.5, 1.0, and 1.5 mM SiO2 under a field capacity—that is, the water content of 60%... Show More
