Abstract/ Executive Summary:

The experiment was conducted at the CRS, Jaintiapur, Sylhet with 3 BARI and 4 commercial mango varieties. A wide variation was observed in case of growth and fruit characteristics. Among the studied varieties BARI Aam-2 showed maximum base girth, canopy size, dense branching with excellent growth condition. The highest number of fruit/plant was found in BARI Aam 3 (92.00) while it was the lowest in Gopalbhog (13.00). The largest fruit size was obtained from Mollika (13.5×8.43 cm) followed by BARI Aam 2 (9.63×8.37 cm). In case of fruit weight the heaviest fruit was found from Mollika (407.0 g) followed by BARI Aam-2 (274.3 g) while the lowest in Gopalbhog (105.3 g). Maximum TSS (20.50%) was recorded from Gopalbhog. Maximum edible portion was manifested from Kamala sinduri (75.49%) while minimum from Langra (59.65%). Maximum yield was obtained from Molllika (6.26 t/ha) followed by BARI Aam-3 (4.3 t/ha). The yield was comparatively lower in all the varieties due to the age of the plant, although fruit cracking was observed in Mollik. But BARI Aam-2 was exceptional retaining all the fruits without any cracking although its yield is lower compared to Mollika and BARI Aam-3.

Objectives:

Study the performance of selected mango varieties under under high rainfall area of North-Eastern region of Bangladesh
To select suitable mango varieties for higher yield and qualities for North-Eastern region of Bangladesh.

Methodology:

The experiment was conducted at the Citrus Research Station, BARI, Jaintapur, Sylhet. The soil of Jaintapur is strongly acidic (pH 4.8) with low organic matter content and poor fertility level. Three BARI released mango varieties namely BARI Aam-1, BARI Aam-2 and BARI Aam-3, and 4 commercial varieties namely Langra, Gopalbhog, Mollika and Kamala sinduri were included in this study. The experiment was laid out in Randomized Complete Block Design with three replications. A single tree of each variety constituted a replication. Fertilizer @ 30 kg cowdung, 1000 g urea, 500 g TSP, 350 g MoP, 350 g gypsum, 20 g zinc sulphate and 15 g borax were applied per plant in two splits in circular trench (60 cm broad, 30 cm deep) 1 m away from the trunk. First split was applied at the end of September and second at the end of April. Weeding was done twice manually following fertilizer application. Three full cover spray applications with Cymcare 10 EC @ 1 ml/L along with Bavistin 50WP @ 2 g/L were done; first at the flower initiation stage when the panicle is around two inches long; second at the pea stage of fruit and third spray at the marble stage of the fruit. These sprays prevented the fruit from attack of mango fruit weevil. Data on tree age, plant height (m), base girth (m), canopy spread (m), branching density, growth condition, time of flowering, time of harvesting, average fruit wt. (g), skin wt. (g), stone wt. (g), fruit length (cm), fruit breadth (cm), edible portion (%), TSS (%), number of fruits/plant, yield/plant (kg) and skin colour were recorded and quantative data were analyzed statistically.
