Effect of Different Water Quality on the Nutritive Value and Chemical Composition of <i>Sorghum bicolor</i> Payenne in Cape Verde
Cape Verde is a semiarid country where lack of rainfall exacerbates the scarce resources available for livestock which, therefore, make it very vulnerable to climate change. By providing reclaimed water (RW) for irrigation, it is possible to decrease forage importation. Subsurface drip irrigation (S...
