Abstract
An experiment was undertaken during the winter season of 2018-19 on tomato (var. Utkal Pallavi), in order to assess the performance of new commercial nano-based water soluble, foliar fertilizer in comparison to commonly adopted water soluble foliar fertilizer with respect to yield, yield attributes and economics. The experiment was laid out in the randomized block design with eight treatments and three replications. Results revealed that the treatment T<sub>6</sub> (Pramukh foliar spray@ 5g/l + RDF- Recommended Dose of Fertilizer@ 125 kg N : 60 kg P<sub>2</sub>O<sub>5 </sub>: 100 kg K<sub>2</sub>O/ha) was found to be the best with respect to the characters like fruit yield (510 q/ha), fruits per plant (81.6), fruit length (5.84 cm) and fruit girth (14.13 cm). As regards average fruit weight, T<sub>3</sub> (Nano- Max NPK foliar spray @5ml/l + RDF) was the best (56.3 g). The treatment T<sub>5</sub> (Pramukh foliar spray @4g/l + RDF) produced the maximum no. of flowers per cluster (9.73) and recorded the highest benefit: cost ratio (3.69). As regards days to 50% flowering, T<sub>1</sub> and T<sub>3 </sub>recorded early 50% flowering (51.0 days after sowing). The treatment T<sub>5 </sub>produced 2<sup>nd</sup> highest yield (509.26q/ha) followed by the treatment T<sub>6</sub> having highest yield and 2<sup>nd</sup> highest benefit: cost ratio (3.68).
