There is a growing interest in raising yields of organic farming to provide more nutritious food for a growing population. Garlic (Allium sativum L.) genotypes cultivated in a variety of environments therefore the yield of garlic can vary considerably between different regions of production. In this research, 21 garlic genotypes were evaluated for their tolerance to nutrient stress under the organic system. Nutrient stress was mediated by organic implementation where two nutrient sources were applied in a newly reclaimed soil; nutrient source-A (plant-derived compost) and B (plant–animal-derived compost). Nutrient stress was adjusted in line with levels, A-1 and B-1 (100% N) and A-2 and B-2 (50% N). Significant differences were observed among garlic genotypes and white-skin genotypes displayed a much greater tolerance for increasing stress level (A-2 and B-2) than colored-skin genotypes. The principal component analysis showed that fresh and cured yields had the largest variances and ranged from 0.9803 to 5.036 t/feddan (fed.) and from 0.633 to 3.445 t/fed., respectively. Elwady and Clone-5 provided the highest fresh yield (4.496 and 4.135 t/fed.) while the highest cured yield was produced from Clone-5 and Clone-22C (2.561 and 2.425 t/fed.). Elwady had the largest N use efficiency and Egyptian improved the agronomic efficiency of N. Elwady, Clone-5, and Egyptian gave the highest stress tolerance indices. Cluster analysis clarified the genotype-specific existence of nutritional stress. Cluster II was found to contain a group of genotypes, Elwady, Clone-5, and Egyptian which closely developed high traits under stress conditions. This genotypes group is a good candidate for organic farming.

有机农业营养胁迫条件下大蒜基因型的相关性及耐受性

人们越来越关注提高有机农业的产量,以便为不断增长的人口提供更有营养的食物。大蒜(Allium sativumL.) 基因型在各种环境中培养,因此大蒜的产量在不同的生产地区之间可能会有很大差异。在这项研究中,评估了 21 种大蒜基因型在有机系统下对营养胁迫的耐受性。营养压力是通过有机实施来调节的,其中两种营养来源被应用于新开垦的土壤中;营养源-A(植物来源的堆肥)和 B(植物-动物来源的堆肥)。营养压力根据水平进行调整,A-1 和 B-1(100% N)以及 A-2 和 B-2(50% N)。在大蒜基因型之间观察到显着差异,白皮肤基因型比有色皮肤基因型对增加的压力水平(A-2 和 B-2)表现出更大的耐受性。主成分分析表明,新鲜和腌制的产量差异最大,分别介于 0.9803 至 5.036 吨/feddan(美联储)和 0.633 至 3.445 t/fed. 之间。Elwady 和 Clone-5 的新鲜产量最高(4.496 和 4.135 t/fed.),而 Clone-5 和 Clone-22C 的腌制产量最高(2.561 和 2.425 t/fed.)。Elwady 的氮利用效率最高,而Egyptian 提高了N.
