摘要: Tropical food legumes are grown in a wide range of environments, and water stress is considered the principal environmental factor limiting growth yield. Potassium fertilizer mitigates impact plants. However, benefits potassium overcoming tropical have not been investigated comparative studies. The purpose this study was to determine mungbean cowpea, two important with different adaptabilities soil moisture regimes. experiment carried out under controlled conditions placed emphasis on vegetative selected physiological parameters. at optimal suboptimal moisture. increased shoot greater extent than cowpea conditions. roots showed response plant relations photosynthetic rates were improved by those cowpea. Although differences observed responses these species potassium, overall terms promoted both when subject While field studies required validate results, application can be significant commonly cropping systems.
