Abstract:
The experiment was conducted with the title of “Effect of foliar application of bio-stimulants on growth, yield and quality of tomato (Solanum lycopersicum)”. The bio-stimulants used are Seaweed extract (Ascophyllum sp. and Sargassum sp.) and Humic acid. The twelve treatments include control (untreated plants); only RDF; RDF + FYM; Asophyllum sp. (1, 1.5 and 2 ml/L); Sargassum sp. (1, 1.5 and 2 ml/L); Humic acid (1.5, 3 and 4.5 ml/L). the foliar spray of these bio-stimulants taken during 20, 40 and 60 days after transplanting Experimental findings revealed that the foliar application of Humic acid at 3 ml/L recorded lesser days to the opening of the first flower (20 days), 50% flowering (22 days), first fruiting (29.33 days) and recorded higher plant height (122.73 cm), leaf chlorophyll content (55.82 (SPAD reading)), Leaf area per plant (2396.34 cm²), root weight (146.80 gm), root length (31.40 cm), shoot weight (1736.45 gm), yield parameters like fruit yield per plant (6.57), number of fruits per plant (69.57), number of fruits per cluster (6.3), average fruit diameter (Equatorial (6.64 cm) and Polar (6.67 cm)), average fruit weight of ten fruits (924.1 gm) and average fruit length (6.10 cm).
