Abstract: A field experiment was conducted at Demo field of Krishi Vigyan Kendra, Theni, Tamil Nadu from 2018 to 2019. The experiment was laid out in a randomized block design and replicated thrice with following eight treatments; T₁ - Control (RDF), T₂ - 100 % RDF+ foliar spray of WSF and IIHR vegetable special, T₃ - 90 % RDF + foliar spray of WSF and IIHR vegetable special, T₄ - 80 % RDF + foliar spray of WSF and IIHR vegetable special, T₅ - 70 % RDF + foliar spray of WSF and IIHR vegetable Special, T₆ - 60 % RDF + foliar spray of WSF and IIHR vegetable special, T₇ - 50 % RDF + foliar spray of WSF and IIHR vegetable special. T₈ - 40 % RDF + foliar spray of WSF and IIHR vegetable special. Different levels of recommended dose of fertilizer were applied at the time of field preparation as a basal dose. Water-soluble fertilizers (19:19:19) and IIHR vegetable special were applied @ 0.25 % (2.5 g L^-1) at different stages of growth, i.e., flowering and fruit-development stage. Among the different treatments tried application of 80 % RDF + foliar spray of WSF and IIHR vegetable Special (T4) resulted higher growth characters, viz., plant height (128 cm), number of leaves per plant (87.05), number of branches per plant (4.55), number of flowers per plant (64.01) and yield attributes viz., number of fruits per plant (44.06), fruit weight (65.04 gm), fruit diameter (4.90 mm), fruit yield per plant (3.20 kg plant^-1) and fruit yield per ha (48.06 t ha^-1). Based on the experimental results, it could be concluded that foliar spray of WSF and IIHR vegetable special along with 80 % of recommended dose of fertilizer could be considered as a better option for achieving higher productivity and profitability and improved quality of Tomato.
