An experiment on Red Cabbage Genotypes planted in different planting densities was conducted during December, 2020 to February, 2021 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 performance of six genotypes of Red Cabbage i.e. (CABRVAR - 1, CABRVAR - 2, CABRVAR – 3, CABRVAR – 4, CABRVAR – 5 and CABRVAR – 6) in two planting densities i.e. (60 x 45 cm and 60 x 60 cm) for plant growth, yield and quality of Red Cabbage, have been discussed and interpreted in the light of previous research work done in India and abroad. The experiment was conducted in 6x2 Factorial Randomized block design with 6 Genotypes of Red Cabbage obtained from different sources, were each genotype replicated thrice in different planting densities. From the present experimental findings it is found that the genotype G2 (CABRVAR - 2) followed by G4 (CABRVAR - 4) was found best in terms of growth, yield and quality parameters of Red Cabbage in planting density D2 (60 x 60 cm) was best in growth and quality parameters and Density D1 (60 x 45 cm) was best in yield parameters. In terms of economics maximum gross return, net return and benefit cost ratio was recorded was recorded in T3 (60 x 45 cm x CABRVAR - 2).
