Characterization of Coleus x hybridus Voss. 'Goldbound' water requirements
Plant water deficit is the major factor limiting global crop productivity. Yield loss caused by water stress is estimated to exceed total loss from all other causes. Moreover, availability of agricultural water is declining worldwide because of increasing demand and decreasing quality. …

Water management practice for maize production in Chinchimane, Zambezi region, Namibia
Agriculture is the greatest water consumer in Namibia and the world at large, it is thus necessary to know the water needs of the irrigated crops for better water management. However, there is little scientific literature on crop water and irrigation requirements in Namibia. Therefore, this study …
