An experiment on Tomato Genotypes at different planting density was conducted during January to May 2020 in Research Field, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.) India. The results of the present investigation, regarding the evaluation of four genotypes i.e. (AVTO – 1706, AVTO – 1707, Arka Samrat and Pusa Ruby) of tomato in four planting densities i.e. (0.2, 0.3, 0.4 and 0.5 m) for plant growth, fruit yield and quality of Tomato, have been discussed and interpreted in the light of previous research work done in India and abroad. The experiment was conducted in 4x4 Factorial Randomized block design with 4Genotypes of Tomato obtained from different sources, were each genotype replicated thrice in different planting densities. From the present experimental findings it is found that the genotype G4 (Pusa Ruby) followed by G3 (Arka Samrat) and planting density D4 (0.5 m) followed by D3 (0.4 m) was found suitable in terms of growth, quality and yield per plant. In terms of yield/plot and per hectare, planting density D1 (0.2 m) was best due to more number of plants per plot and per hectare area. In terms of economics maximum gross, net return and cost benefit ratio was recorded in genotype G4 (Pusa Ruby) and minimum in G1 (AVTO - 1706).
