Drought is the most important limiting factor of the agricultural plants production in Egypt and the world. Nitrogen application management under water limited condition needs to be refined for low yielding environments. Therefore, to see how restricted irrigation and different nitrogen fertilizer affect yield, its components, water use efficiency and nutrients uptake of wheat, an experiment was conducted in a semi-arid area in Assiut, Upper Egypt in 2013/2014 and 2014/2015. Split-plot experimental design was used, based on a complete randomized block design with three replications. The variables were two water treatments and three levels nitrogen fertilization. The main plots were used to express irrigation regimes (100% of water requirements (I 100 = 5370 m 3 ha −1 ) and 75% water requirements (I 75 = 4027 m 3 ha −1 )). The split units were assigned for nitrogen fertilizer levels (N 120 =120, N 180 =180, and N 240 =240 kg ha −1 ). The results showed that fertilization o...

On the meadow-chestnut soil of heavy mechanical composition we studied the productivity of promising varieties of winter durum wheat Grain, de-pending on the doses and timing of mineral fertilizers on the background of irrigation and semi-steam systems of soil treatment in irrigation of the flat zone of Dagestan. The purpose of the research was to obtain experimental data for the development of cost-effective and environmentally friendly resource-saving technology of cultivation of promising varieties of winter durum wheat Grain in the flat zone of Dagestan. The novelty of the research is that for the first time in the conditions of irrigation of the flat zone of Dagestan, the optimal doses of mineral fertilizers and the terms of their application for winter durum wheat, providing a significant in-crease in yield and grain quality were studied and established. On average, for 2014-2018 the maximum yield of the promising Grain variety-5.45 t/ha, on aver-age for 2014-2018, wa...

The study aimed to provide valuable information for the promotion of vine by-products in fuelling small-to-medium size enterprises near wine/spirit processing industries. The objective was to evaluate and compare the ashes produced from both fixed and fluidized bed combustion of these wastes and their mixtures. Ashes were characterized by mineralogical, chemical, thermal and fusibility analyses and water leaching tests were conducted to remove problematic elements. Slagging/fouling propensities of ashes were determined, and their environmental impact and potential uses were assessed.
