Abstract:
A field experiment was conducted to study the influence of organic manures and bio-fertilizers on plant growth parameters during the years 2019 to 2021 on two different types of dragon fruit in Mr. Sandeep Gowda’s field located at Suradhenupura, which is 20 kms away from, UAS, GKVK, Bengaluru. The experiment was laid out in randomized complete block design (RCBD) with thirteen treatments replicated thrice. Treatments comprising viz. T1 – Control (No manure), T2 - 100% N through FYM, T3 - 100% N through FYM + PSB @ 10kg/ha, T4 - 100% N through FYM + VAM @ 10kg/ha, T5 - 100% N through FYM + PSB @ 10 Kg/ha + VAM @ 10kg/ha, T6 - 100% N through poultry manure, T7 - 100% N through poultry manure + PSB @ 10kg/ha, T8 - 100% N through poultry manure + VAM @ 10kg/ha, T9 - 100% N through poultry manure + PSB @ 10 Kg/ha + VAM @ 10kg/ha, T10 - 100% N through vermicompost, T11 - 100% N through vermicompost + PSB @ 10kg/ha, T12 - 100% N through vermicompost + VAM @ 10kg/ha, T13 - 100% N through vermicompost + PSB @ 10 Kg/ha + VAM @ 10kg/ha. The pooled data from two year study for red and white fleshed dragon fruit revealed that treatment T13 comprising of 100 per cent N through vermicompost + PSB at 10 kg ha-1+ VAM at 10 kg ha-1 had significantly higher effect on the parameters maximum plant height (409.85 and 396.73 cm), number of branches per plant (9.43 and 9.32), plant spread in North-South (180.96 and 175 cm) and East-West directions (168.33 and 170.16 cm), circumference of the main stem (19.76 and 19.55 cm), diameter of the stem (15.12 and 14.98 cm), number of new sprouts (7.03 and 6.80) and height of the new shoot (70.14 and 22.49 cm).
