Response of wedge grafting and time on survival of mango (Mangifera indica) in polyhouse and open field condition

The experiment was conducted to find out optimum time for wedge grafting in mango (Mangifera indica L.) on different dates of grafting, viz. 15 November (D₁), 1 December (D₂), 15 December (D₃), 1 January (D₄), 15 January (D₅), 1 February (D₆),15 February (D₇) and 1 March (D₈) under polyhouse condition and open field condition. Wedge grafting gave more yield in March in polyhouse (69.31%) and open field condition (59.70%). There was better response to height of plants in polyhouse condition than open field condition The height of grafted plants was 46.09 cm, length of graft union 4.59cm and stem girth 1.55cm. The time taken for first sprout (9.33 cm), number of sprouts (9.08), length of sprout (21.45), number of leaves / plant (23.30), fresh weight of leaves (27.13), dry weight of leaves (18.15), fresh weight of grafted plant (75.30), dry weight of grafted plant (18.96).
