Monitoring Nutrient Uptake of Chard (Beta vulgaris var. cicla L.) Exposed to Exogenously Applied Nitric Oxide under Drought Stress

Nutrient uptake of chard under well-watered and drought conditions with different NO applications were investigated in this research. solutions prepared four doses (0, 50, 100, 150 200 µM) sodium nitroprusside as a nitric oxide source exogenously applied on only seeds (s) or together seed foliar (sf) levels according to 100% (control), 67% 33% the water required reach field capacity. drastically decreased stress. However, progressive effects nutrient have been observed both drought. The increase N P plant significant especially for 100 µM s sf applications. highest Fe, Cu Zn content obtained from application, while Mn B application level. level Fe application.
