Abstract
Salt stress is one of the most devastating abiotic stress which severely affects the agricultural productivity in various ways. A study was undertaken to investigate the tolerance and mitigation of salt stress in tomato by exogenous application of calcium (Ca 2+ ). The experimental results showed that salt stress significantly affects morphology, physiology and fruit weight of tomato. Plant height, leaf number and branch number/plant were decreased with increased levels of salinity mostly at 6 and 8 dS mG 1 . Salinity also adversely affected the shoot dry weight, leaf area, leaf chlorophyll content and also fruit weight/plant mostly at 8 dS mG 1 . Exogenous application of Ca 2+ significantly mitigates the adverse effects of salinity on plant biomass production or morphology, physiology and fruit production. The plant height, leaf number/plant, branch number/plant, dry weight of shoot/plant, leaf chlorophyll content, fruit weight/plant were increased with the application of calcium in saline condition compared to without calcium. The fruit weight of tomato is gradually decreased with the increased levels of salinity. In case of treatment combinations, the reduction rate of fruit weight of tomato was decreased with increased levels of Ca 2+ in response to different saline conditions and the lowest fruit weight was recorded at the highest salinity level (8 dS mG 1 ) along with without Ca 2+ .
