Abstract
Tomato is an important vegetable crop all over the world due to its nutritional and medicinal value. Its demand is increasing while its production is adversely affected by the changing climate. There is a need to adopt such strategies to cope with the changing climate and improve fruit production under changing climatic conditions. This study was designed to evaluate the effect of salicylic acid on tomato plants and its production. During this study the salicylic acid’s effect was evaluated on tomato plants grown under the Chinese solar greenhouse during the two growing seasons 2021 and 2022. Different concentrations of salicylic acid (0 mM, 0.5 mM, 0.75 mM and 1 mM) were sprayed on tomato plants at an interval of 14 days from transplanting to the first harvest stage. Its effect was studied on both morphological and biochemical properties of tomato plants. The results revealed that the 0.75 mM concentration of SA has a positive effect on both the traits i.e., morphological such as plant height (154.33 cm and 141.33 cm) number of clusters (17 and 15.667) and biochemical characters such as total soluble solids (4.733 ºBrix and 4.8 ºBrix) titratable acidity (0.7827% and 0.8107%) of tomato. 0.75 mM concentration of SA has significant effect on the tomato plant and improved the morphological and biochemical characteristics of plants. Thus, the 0.75 mM concentration of SA is found optimal for improving the quality and quantity of tomato fruits
