This study investigates Mg concentrations and productivity in seven spring wheat genotypes (YR, Local, Sids 12, P3, P5, IC8, and IC17) by evaluating their nutritional content and their responses to organic and conventional fertilization methods. We employed a randomized complete block design (RCBD) with three replications and observed that conventional fertilization resulted in higher Mg levels than organic fertilization (2.12 vs. 1.54 g kg). The application of conventional fertilizers also resulted in a higher shoot dry weight compared with the application of organic fertilizers (4.6 vs. 1.88 g), with Sids 12 recording the highest shoot dry weight (4.79 g), followed by YR (3.39 g). Furthermore, conventional fertilization consistently yielded a higher grain output than that of organic fertilization across both seasons. P5 and IC17 had superior grain yield and Mg content in grains, respectively. Wheat yields were lower under organic fertilization than under conventional practices. Some genotypes, such as YR and IC17, experienced significant yield reductions under organic conditions, whereas others, such as P5, displayed resilience or even enhanced yields. The IC17 genotype demonstrated minimal variation in Mg content in grains between conventional and organic fertilization, highlighting genotype-specific responses to fertilization methods. Thus, selecting and cultivating the appropriate genotype can facilitate achieving nutritionally adequate wheat production under organic farming conditions in Saudi Arabia.
本研究通过评估七种春小麦基因型（YR、本地种、Sids 12、P3、P5、IC8和IC17）的营养成分及其对有机施肥和传统施肥方法的反应，来调查镁浓度和生产力。我们采用了随机完全区组设计（RCBD），重复三次，观察到传统施肥的镁含量高于有机施肥（2.12对1.54克/千克）。与施用有机肥料相比，施用传统肥料还导致地上部干重更高（4.6对1.88克），其中Sids 12地上部干重最高（4.79克），其次是YR（3.39克）。此外，在两个季节中，传统施肥的谷物产量始终高于有机施肥。P5和IC17分别具有较高的籽粒产量和籽粒镁含量。有机施肥下的小麦产量低于传统施肥。一些基因型，如YR和IC17，在有机条件下产量显著降低，而其他基因型，如P5，则表现出抗逆性甚至产量增加。IC17基因型在传统施肥和有机施肥下籽粒中的镁含量变化最小，突出了基因型对施肥方法的特异性反应。因此，选择和培育合适的基因型有助于在沙特阿拉伯的有机农业条件下实现营养充足的小麦生产。
