BUNCH BAGGING EFFECT ON FRUIT SETTING AND QUALITY OF FRUIT IN DIFFERENT LITCHI GERMPLASM
Abstract
An experiment was carried out at the BAU Germplasm Centre (GPC), Bangladesh Agricultural University, Mymensingh during February to May, 2021 to study the effect of bagging on fruit setting and fruit quality of different litchi germplasm. The experiment was laid out in a Randomized Complete Block Design with three replications of four litchi germplasms viz. Mongolbari, China-3, Bombai, Mozzafforpuri. Here replication number is represented by number of plants observed per variety. The data were recorded on number of fruit set per inflorescence, fruit dropping, fruit color, weight per fruit, TSS (% brix). At marble stage, bunch bagging was done with brown and white polypropylene bag and bunches were without bagging in control plants. Bunch bagging has significantly influenced on yield and yield attributes of litchi germplasms. The highest fruit setting was obtaining from Bombai litchi with brown polyethylene bag followed by Mongolbari with white polyethylene bag, while non-bagged China-3 obtained the lowest fruit setting. Mongolbari had highest TSS (18.65% Brix) in brown polypropylene bag treatments. Bolder fruit (21.15g) was found in Bombai on brown polypropylene bag treatment and small fruit (12.83g) from China-3 in control. Attractive fruit color, no/less fruit cracking, no bird damage was found on bunch bagging treatment at ripening which may add more consumer value of litchi. Based on the study it can be concluded that as a good agricultural practices (GAP) timely establishment of brown polypropylene bunch bagging was the best to reduced fruit dropping as well as increased the average fruit weight, fruit color and %TSS value of litchi fruit.
