Effect of water soluble fertilizers on growth and yield of tomato (Solanum lycopersicum L.)

摘要

Investigation on the effect of water soluble fertilizers (starter and booster) on growth and yield of tomato was carried out at P.G centre, UHS campus, GKVK, Bengaluru during summer season, 2011. Combination of starter and booster at 2% along with RDF resulted in a significant increase in growth parameters like plant height (100.40 cm), number of leaves (60.2), number of branches (23.4), total chlorophyll content (1.25 mg g-1), leaf area index (4.16) and dry weight per plant(178.37 g). Among different yield attributes, a significant increase was observed in fruit setting percentage (81.07), number of fruits per plant (38.60), fruit volume (63.0 ml), fruit size (10.98 cm2), average fruit weight (55.60 g), yield per plant (2.03 kg) and yield per hectare (39.87 Mg ha-1) due to the application of both starter and booster at 2% along with RDF. However, early flowering (27.25 days) and early harvest (54.97 days) were recorded with application of water soluble fertilizer at 1.5% along with RDF.
