Physiological and biochemical responses of soybean (Glycine max L.) to cysteine application under sea salt stress

Bulletin of the National Research Centre

Table 6 Effect of cysteine (0, 20, and 40 mg/l) on seed yield, yield components, and oil content of soybean plant irrigated with saline water (0, 3000, and 6000 mg/l). Results are means of two successive seasons
