The experiment was carried out 2018 at the University of Agriculture Peshawar-Pakistan to investigate the influence of different plant extracts and salicylic acid as a foliar spray on growth, yield and fruit quality of tomato (Cv. Rio Grande).The design of the experiment was a Randomized Complete Block Design (RCBD) with split plot arrangement with three replicates were used.  Different levels of plant extracts i.e (control, moringa 6% neem 10% and garlic 4%) and Salicylic acid concentrations i.e (Control, 2, 4 and 6mM) were applied for foliar application. Results indicated that foliar application of plant extracts (moringa 6%) gave Maximum chlorophyll content (0.0511 mg cm-2), plant height (90.44 cm), single fruit weight (57.79 g), fruit volume (55.68 cm3), fruit firmness (3.63 kg cm-2), titratable acidity (0.40 %) and ascorbic acid (11.76 mg 100gm-1) content, while maximum pH was recorded in control treatment. Whereas salicylic acid concentration (6mM) also effected all the attributes as compared to all treatment. maximum chlorophyll content (0.0522 mg cm-2), plant height (88.38 cm), single fruit weight (54.91 g), fruit volume (51.91cm3), fruit firmness (3.28 kg cm-2), titratable acidity (0.37 kg %), and ascorbic acid (10.87 mg 100g-1) content with minimum fruit juice pH (4.19) was recorded.
