Soil salinity and atmosphere temperature change have negative impacts on crop productivity and its quality and can pose a significant risk to soil properties in semi-arid regions. We conducted two field experiments in North (first zone) and South (second zone) of Egypt to investigate the effects of soil bagasse ash (10 ton ha⁻¹), foliar thiourea (240 g ha⁻¹) and their combination in comparison to the control treatment on saline soil properties and productivity and quality traits of wheat. All studied treatments were received the recommended rate of N, P and K fertilizations. Combination of soil bagasse ash and foliar thiourea application resulted in a significant improvement of most studied soil properties (i.e. EC, compaction, hydraulic conductivity, OM and available P, K, N contents) after harvest in comparison to other treatments in both of zones. Also, it enhanced growth and grain yield of wheat in terms of photosynthesis related attributes and yield components. Moreover, combination of soil bagasse ash and foliar thiourea application resulted in superior grain quality traits in terms of carbohydrate, fibre, protein and ash contents than separated application of soil bagasse ash, foliar thiourea or even control treatment. In conclusion, combination of soil bagasse ash and foliar thiourea application can be used as suitable option to enhance plant nutrition, wheat productivity and improve wheat grain quality and soil traits in saline soil as well as can alleviate heat stress.

土壤盐分和大气温度的变化对农作物的生产力及其质量产生负面影响，并可能对半干旱地区的土壤特性造成重大风险。我们在埃及的北部（第一区域）和南部（第二区域）进行了两次野外试验，以研究土壤蔗渣灰分（10吨公顷^-1），叶硫脲（240克公顷^{-1）的影响}）及其组合，与对照处理相比，盐碱土壤特性以及小麦的生产力和品质性状。所有研究处理均获得推荐的氮，磷和钾肥施用量。与两个地区的其他处理相比，土壤蔗渣灰和叶面硫脲的结合导致收获后大部分研究的土壤特性（即EC，压实度，水力传导率，OM和可用的P，K，N含量）显着改善。此外，从光合作用的相关属性和产量构成方面来看，它还增强了小麦的生长和谷物产量。此外，与单独施用土壤蔗渣灰相比，土壤蔗渣灰和叶面硫脲的组合产生的碳水化合物，纤维，蛋白质和灰分含量方面的谷物品质性状优异，叶硫脲甚至控制治疗。总之，土壤蔗渣灰和叶硫脲的组合施用可作为增加盐分土壤中植物营养，提高小麦产量，改善小麦籽粒品质和土壤性状以及减轻热胁迫的合适选择。
