Impact of Different Size of Polybags on Mango Grafts Under Protected Structures

Abstract

The present investigation entitled "Impact of different size of polybags on mango grafts under protected structures" was carried out at Fruit Nursery, Department of Fruit Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra during the year 2022-23 with the objectives to study the effect of different poly bag size and protected structures on success and survival of mango grafts. The experiment was laid out in Factorial Randomized Block Design with factor A as different poly bag size viz., B 1 (6''×9"), B 2 (7''×11'') and B 3 (8''×12") and Factor B as protected structures viz., S 1 (Insect proof net), S 2 (50% green shade net), S 3 (70% green shade net), S 4 (Polytunnel) and S 5 (Open conditions) replicated four times. The result of the present investigation revealed that the polybag size B 3 was significantly superior in the length of scion (17.58 cm), number of leaves per graft (14.64) and diameter of graft union (7.15 mm) as compared to B 1 and B 2 at 150 DAG. Study on protected structures revealed that at 150 DAG the length of scion (19.10 cm), the maximum number of leaves (15.33), the diameter of graft (7.29 mm), the success percentage (79.16%) and final survival percentage (86.74%) of grafted plants was recorded to be superior in S 1 followed by S 2 as compared to other treatments. The interaction between poly bag size and protected conditions revealed that treatment combination S 1 B 3 was significantly superior in length of scion (21.74 cm), number of leaves (16.61) and diameter of graft (7.66 mm) as compared to other treatment combinations at 150 DAG.
