The effects of climatic change mediated water stress on growth and yield of tomato

Climate change especially water stress affect the crop productivity in many regions of the world. The current paper survey the effect of water weight on development and organic product yield of tomato. Winter cultivar (BARI Tomato-14) was grown under different levels of moisture stress (control, 75 and 50% evapotranspiration moisture) in pot experiment using randomized total square plan with three replications. The investigation results appeared that increased moisture stress progressively reduced plant height (92.73, 90.06, and 75.58 cm), leaf area (198.69, 187.56, and 176.66 cm2), chlorophyll content (47.41, 40.87 and 38.10), leaf dry matter (18.07, 16.27, and 12.24), number of branch (13.55, 12.06 and 10.00) and leaf number (22.93, 22.44, and 20.34) under control 100, 75, and 50% of evapotranspiration conditions, respectively. The outcome additionally indicated a noteworthy and positive connection between organic product yield and development and physiological parameters. The most elevated connection was seen between organic product yield and leaf number (r2=0.97) trailed by chlorophyll content (r2=0.95). Consequently, leaf number and chlorophyll content is a suitable index for assessment of water stress and tomato genotypes tolerant.
