Abstract: An investigation was carried out to study the effect of various mycorrhizal products on growth, yield, and quality parameters of tomato (Solanum lycopersicum L.) cv. Arka Vikas. The experiment was conducted at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, BHU, Varanasi during Rabi season of 2016-17. From the analysis, it is clear that T₂ - Soil application with Myc100 @ 250 g/ha has proven to be best with respect to most of the characters viz., number of nodes per plant (23.57), root length (49.47 cm), number of fruits per plant (31.00), fruit length (5.69 cm), average fruit weight (91.95 g), fruit yield per plant (2696.27 g), fruit yield/plot (67.41 kg), fruit yield (748.96 q/ha), and TSS (4.86 ºBrix) whereas T₇ - Foliar application with Ratchet @ 300 mL/ha 2 applications at 30 and 60 DAT got highest value (132.17) concerning the plant height (cm) and for the traits like Internodal length (6.76 cm), days to 50% flowering (33.33), and flower drop (33.31%), T_{1 -} Untreated Control has obtained the highest value. From the investigation, it can be concluded that the best product in relation to the growth, yield, and quality parameters was T₂ - Soil application with Myc100 and the optimum concentration for its application is 250 g/ha.
