Performance and Economical Cost Analysis of Different Radish (Raphanus sativus L.) Varieties under Sub Tropical Conditions of Central India

The present study was carried out at Research cum Instructional Farm of College of Horticulture and Research Station, Jagdalpur, Chhattisgarh, during the Rabi season of 2021 to investigate the selection of superior radish varieties having high yield potential with better quality root for Bastar plateau. The experiment was laid out in randomized block design (RBD) with fifteen treatments and three replications. The fifteen varieties of radish, used for study as treatments were viz. Pusa Chetki, Pusa Mridula, Pusa Shweta, Pusa Gulabi, Pusa Jamuni, Kashi Hans, Kashi Muli 40, Kashi Lohit, Chinese Pink, MRH111, Snow White, Mino Early, Ivory White, R-30 and Palak Patta (check). The growth attributing characters of radish varieties expressed in terms of days to 50 per cent germination and days to harvest were significantly the earliest in Pusa Mridula (6.33 and 47.33 respectively); plant height, fresh weight of roots, dry weight of roots, root yield (kg plot-1) and root yield (t ha-1) were the maximum in Kashi Lohit (37.69 cm, 153.75 g, 26.27 g, 7.69 kg plot-1 and 38.44 t ha-1) respectively number of leaves plant-1, East-West spread of the plant, fresh weight of leaf and leaf area index in Pusa Jamuni (13.33, 33.43 cm, 109.59 g and 5.47 respectively); North-South spread of the plant in Ivory White (46.50 cm); fresh and dry weight of plant in Kashi Muli-40 (254.93 g and 30.28 g respectively), dry weight of leaf in Mino Early (11.00 g) While, Pusa Gulabi recorded the maximum leaf yield kg plot-1 and leaf yield t ha1 (5.48 kg plot-1 and 27.40 t ha-1 respectively). Among all the treatments significantly higher length of root (31.03 cm), diameter of root (5.65 cm) and root to shoot ratio (2.17) at harvest were observed in variety R-30, Pusa Chetki and Kashi Hans respectively. The results depicted that Kashi Lohit produced significantly the maximum net income, gross income and benefit-cost ratio (Rs 3,84,373.30 ha-1; Rs 2,87,580.30 ha-1 and 2.97 respectively) among the other treatments.
