Abstract: Global warming and climate change are factors that lead to an increase in droughts. Drought impairs plant growth and development consequently affecting crop yield. Thus, plants develop certain measures that lead to adaptation of drought stress for better plant growth under the stress conditions. The effect of drought stress on osmolytes (glycine betaine and carbohydrate) and chlorophyll concentrations was studied in three cowpea varieties. Results showed a significant increase in the concentration of carbohydrate and glycine betaine as the stress period increased and a significant decrease at the re-watering period in the drought-tolerant and local varieties. However, there was a significant decrease in the concentration of chlorophyll in all three varieties studied as the stress period increased. Osmolyte and chlorophyll played a role in the drought response of cowpeas.
