Abstract/ Executive Summary:

The present experiment was conducted at the Germplasm Centre (GPC) of the Fruit Tree Improvement Program (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh, during the period from August, 2010 to October, 2011 to investigate the effect of growing conditions and time of operation on the success and survivability of cleft grafting of mango (cv. BAU mango-1). The experiment consisted of two factors, such as (i) two growing conditions viz., open condition and polyhouse condition and (ii) twelve time of grafting operations.The experiment was laid out in Randomized Complete Block Design with three replications. Results revealed that, the lowest time to bud break (13.01 days) and leaf opening (18.57 days) with the highest graft height (59.90 cm), number of leaves (13.75), graft success (96.85%) and survivability (96.00%) were required by the grafts under polyhouse condition with June grafting. On the other hand the highest time to bud break (18.83 days) and leaf opening (26.45 days) with the lowest graft height (47.64 cm), number of leaves (9.00), graft success (44.53%) and survivability (38.91%) were needed by the graft in open condition when those were grafted in January.

Program Area: Variety and Species

Commodity: Mango

Objectives:

To study the effect of growing conditions and time of grafting operation on the success and survivability of cleft grafting of mango (cv. BAU Mango-1).

Methodology:

The present experiment was conducted at the BAU-Germplasm Centre (GPC) of the Fruit Tree Improvement Program (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from August, 2010 to October, 2011. High yielding cultivar namely BAU Mango-1 was used in this study. The experimental area is situated under the sub-tropical monsoon climate, which is characterized by high temperature, high humidity and heavy rainfall during the months of April to October and scanty rainfall associated with moderately low temperature during the rest period of the year. Experimental materials were rootstock and scion of mango. The rootstocks used in the experiment were raised in polybag from the mango seeds of unknown variety. The scion shoots used, were collected from the mother plants of mango (cv.BAU Mango-1). The two-factor experiment consisting of 24 treatment combinations was laid out in Randomized Complete Block Design (RCBD) with three replications. For each treatment combination grafting operations were performed on unknown rootstocks of each block. Thus in total 432 grafts (2×12×3×6) were made. The treatment combinations were randomly assigned to each unit, so as to allot one treatment combination once only in each block. The experiment consisted of two factors, details of which are described below: Factor A. two growing conditions viz., open condition and polyhouse condition and Factor B: twelve time of grafting operations viz., 1st week of August, September, October, November, December, January, February, March, April, May, June and July. Canopy volume was calculated at an interval of 30 days starting from 30 days after grafting and was continued upto 90 days. The data collected from the experiment were statistically analyzed. The mean values of all treatments were calculated and the analysis of variance for most of the characters was accomplished by F variance test. The significance of difference among the treatment means was evaluated by least significance difference (LSD) test at 5% and 1% levels of probability.
