A study was conducted in the farmer's field at Suradhenupura, Doddaballapur taluk, which is located 20 kms away from University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru during the year 2019-2021 to investigate the 'Effect of organic manures and bio-fertilizers on plant growth and yield of dragon fruit (Hylocereus undatus (Haworth) Britton & Rose.) and (Hylocereus polyrhizus (F.A.C. Weber) under Eastern Dry Zone of Karnataka'. The experiment was planned by adopting randomized complete block design (RCBD) consisting of 13 treatments with three replications. Each pillar consisted of four plants. Maximum plant height of 385.83 cm and 395.67 cm, number of branches per plant of 7.74 and 7.83, circumference of main stem of 14.98 cm and 15.10 cm, number of new sprouts of 6.50 and 6.52, plant spread from North to South of 174.15 cm and 180.59 cm, plant spread from East to West of 167.33 cm and 172.90 cm, stem diameter of 19.55 cm and 19.74 cm and height of new shoot of 65.45 cm and 68.21 cm, maximum yield of 4.5 kg plant-1 and 18.33 kg pillar-1 and 6 kg plant-1 and 24 kg pillar-1 was obtained in both white and pink fleshed dragon fruit, respectively. Among different treatments, T-13 comprising of 100 per cent N through vermicompost + PSB @ 10 kg ha-1 along with VAM @ 10 kg ha-1 showed superiority in growth and yield of white fleshed and pink fleshed dragon fruits.
