Classification of drought tolerant cowpea [Vigna unguiculata (L). Walp)] genotypes based on morphological and physiological responses to water deficit
King, Charles F. Jr. (Botswana University of Agriculture & Natural Resources, 2015-11)Drought stress poses a major threat to food security due to the devastating effect during the growth and development of plants and leads to yield losses in Africa, especially in Botswana. Therefore, there is an increasing ... -
