We need to produce higher foods even under declining natural resources to feed the projected population of 9 billion by 2050 and to sustain food security and nutrition. Abiotic stress has adversely affected canola crop and oil quality especially in sandy soils. To combat this stress, adaptation at the farm level using new and cost-effective amendments are required. Field trials were conducted in two different climatic zones to determine the efficacy of cane molasses, bagasse ash, sugar beet factory lime, and their compost mixtures to improve soil quality and heat stress-adapting canola. The results showed a significant improvement in bulk density, hydraulic conductivity, organic matter content, and available macronutrients of sandy soil and subsequent canola growth, yield, quality and water productivity due to the application of the tested soil amendments, particularly those mixed with compost. Despite the estimated reduction of yield by 18.5% due to heat stress, application of sugar beet lime and compost mixture not only compensated for this reduction but also increased the seed yield by 27.0%. These findings highlight the value of recycling compost-based sugar crop disposal as a cost-effective technology to boost crop tolerance to abiotic stress, ensuring sustainable agriculture and food security in arid environments.

即使在自然资源减少的情况下，我们也需要生产更高的食物，以在2050年之前养活90亿的预计人口，并维持粮食安全和营养。非生物胁迫已对油菜籽作物和油质产生不利影响，尤其是在沙质土壤中。为了应对这种压力，需要使用新的且具有成本效益的修正案在农场一级进行适应。在两个不同的气候区进行了田间试验，以确定蔗糖蜜，蔗渣灰，甜菜工厂石灰及其混合肥料的功效，以改善土壤质量和适应热胁迫的油菜。结果表明，沙质土壤的容重，水力传导率，有机质含量和可利用的大量养分以及随后的油菜生长，产量，由于使用了经过测试的土壤改良剂，尤其是与堆肥混合的土壤改良剂，因此其质量和水生产率更高。尽管估计由于热胁迫导致单产降低了18.5％，但施用甜菜石灰和堆肥混合物不仅弥补了这种降低，而且使种子单产提高了27.0％。这些发现凸显了基于堆肥的糖料循环再利用的价值，该技术是提高作物对非生物胁迫的耐受性，确保干旱环境中可持续农业和粮食安全的一项具有成本效益的技术。
