A field experiment was carried out at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during the Rabi 2021-2022 with a view to determine the performance of different varieties of spinach beet (Beta vulgaris var. bengalensis) for its growth, yield under Prayagraj climate and to work out the economics of various treatments. Under this experiment, overall 7 varieties were sown under tags T1 (Pusa Jyoti), T2 (All Green), T3 (All Green H-1), T4 (Green Iron), T5 (Palak- Ashirwad), T6 (Sudevi Green Spinach), T7 (Supriya) which was laid out in randomized block design (RBD) with three replications. From the present investigation, it was concluded that variety Pusa Jyoti performed best in respect of all parameters specially yield (64.44q/ha) at Prayagraj climatic condition. The benefit-Cost ratio (1.61) of variety Pusa Jyoti was found to be the highest therefore, it can be suggested to farmers to adapt it in cultivation practices.
