Abstract

The amount of water utilized by the plant has a significant impact on its yield. In this regard, yield response factor (Ky) permits measuring yield decline as a function of evapotranspiration. As a result, the purpose of this study was to calculate Ky for the sunflower crop grown in North Nile Delta, Egypt and to calculate economic water productivity. Seasons 2021 and 2022 were studied. The experiment used a complete randomized block design with three replicates. W1 (50-55%), W2 (55-60%), and W3 (60-65%) maximum allowable depletion of available soil moisture (MAD of ASW) treatments were used. In total, the average two seasons (0.52 and 0.61) found for sunflower crop under W2&W3, respectively, demonstrated its strong sociability to water deficit. Its yield is substantially impacted by water availability, with average 0.65 & 0.47% loss in yield for every 1% reduction in evapotranspiration with w2 and w3 treatments, respectively. The treatment without stress, w1 (50-55% MAD of ASW), yielded the highest grain yield. However, after considering water and irrigation costs, it could conclude that other stressed treatments, W2&W3, were more cost-effective.

向日葵作物对不同土壤水分消耗水平的反应
植物利用的水量对其产量有重大影响。在这方面,产量反应因子(Ky)可以测量产量下降与蒸散量的函数关系。因此,本研究的目的是计算埃及北尼罗河三角洲向日葵作物的 Ky 值,并计算经济水分生产率。研究季节为 2021 年和 2022 年。实验采用完全随机区组设计,设三个重复。采用了 W1(50-55%)、W2(55-60%)和 W3(60-65%)可用土壤水分最大允许消耗量(MAD of ASW)处理。总之,在 W2 和 W3 条件下,向日葵两季的平均产量分别为 0.52 和 0.61,这表明向日葵对缺水有很强的适应性。向日葵的产量受水分供应的影响很大,在 W2 和 W3 处理下,蒸散量每减少 1%,产量平均分别减少 0.65% 和 0.47%。无胁迫处理 w1(50-55% MAD of ASW)的谷物产量最高。然而,考虑到水和灌溉成本,可以得出结论,其他胁迫处理 W2 和 W3 更具成本效益。
