Abstract: Photosynthetic pigments are responsible for conversion of light energy into a form of chemical energy in the plants. The most important pigment in the light harvesting machinery of the plant is chlorophyll and Carotenoids play an important role in photoprotection of chlorophyll molecules. Cowpea responds to survive under water-deficit conditions via a series of physiological, cellular and molecular processes culminating in stress tolerance. Most cowpea is produced in arid and semi-arid zone. This experiment was conducted in the research field of Department of Biological Sciences, Sam Higginbottom Institute of Agricultural Technology and Sciences, Allahabad. To study the chlorophyll a, chlorophyll b and carotenoid content of three cowpea varieties (UU-0, VU-89 and KK-6) subjected to the different level of watering (daily watering, 2 days interval, 4 days interval and 6 days interval of watering). The experimental materials were arranged in Randomize Complete Block Design. The results indicate that the all photosynthetic pigments such as chlorophyll a, chlorophyll b and carotenoid content maximum in daily watering whereas at 6 days interval of watering observed minimum.
