Effect of soil application of zinc and boron on growth parameters of Dragon fruit (Hylocereus polyrhizus L.)

The present study was conducted during 2023-24 and 2024-25 at college of Agriculture, IGKV, Raipur, with the objective to know the Effect of soil application of zinc and boron on growth parameters of Dragon fruit. The results revealed that the effect of factor A (zinc) Z3 , factor B (boron) B3 and their treatment interaction T16 (Z3 B3 ) - Zinc sulphate @ 9 g per pole + Boron @ 6 g per poleunder recorded significantly maximum growth parameters viz., plant height (4.07, 4.26 and 4.23 m), plant canopy in North-South direction (2.63, 2.70 and 2.83 m), plant canopy in East-West direction (2.005, 2.017 and 2.241 m), number of flower bud per pole (41.45, 42.58 and 47.33), day to first flowering (9 May and 18 May) and fruit set (63.53, 65.78 and 72.66 %) followed by effect of factor A (zinc) Z2 , factor B (boron) B2 and their treatment interaction T12 (Z2 B3 ) - Zinc sulphate @ 6 g per pole + Boron @ 6 g per pole during the pooled years data respectively.
