Effect of Bagging Time on Fruit Quality and Shelf Life of Mango (Mangifera Indica L.) Cv. Langra in Bangladesh

Abstract

The present experiment titled "pre harvest bagging enhanced quality and shelf life of mango cv. Langra" was conducted during the year 2017 at the mango orchard near Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. The research was carried out in the Randomized Complete Block Design with three replications. Mango fruits were bagged at 35, 45 and 55 days after fruit set with different types of bags which constituted various treatments viz.: T1: Transparent polythene bag, T2: White paper single layered bag, T3: Brown paper double layered bag, T4: control (no bagging). In fruit physical parameter result bagged at 35 days after fruit set with white paper and brown paper bag recorded maximum fruit length (97.93 and 103.5 mm), fruit diameter (79.27 and 84.85 mm), fruit weight (311.66 g and 329.2 g), pulp weight (278.9 g and 289.8 g) respectively, and minimum result was found in polythene bag and control. Meanwhile in fruit chemical parameter of total sugar, reducing and non-reducing sugars, total soluble solids, ascorbic acid, pH and β-carotene were improved over control. Brown paper bag changed fruit color. The sensory qualities in fruits of brown and white paper bags were improved over control. Fruits treated with brown paper bag showed shelf life upto 11 days with lowest weight loss and good physical quality as against 6days of unbagged fruits (control). These results specify that fruit bagging can improve fruit quality through diminution in disease and insect-pest infestation and shelf life of mango cv. Langra.

Effect of Bagging on Quality and Shelf Life of Mango (Mangifera indica L.) cv. BARI Mango- 4

“…During ripening stage, white paper bag exhibited maximum total sugar (5.96%) whereas minimum (4.00%) was recorded in polythene bag (Table 3). These results are very close to the earlier findings [31,4]. They reported that bagged fruits of mango and palm exhibited the maximum total sugars at ripening stage (Table 3).…”

“…Pre-harvest fruit bagging has been widely used in various fruit crops, such as mango [3,4,16], apple [17], pear [18], peach [19], to enhance the commercial standard of the fruit, namely, promoting fruit coloration [20], reduces mechanical damage [21] and sunburn [22] of the skin. Pre-harvest bagging also reduces the use of pesticides in the fruit and controlling insect [23], disease [24] and bird damage.…”

“…As a result, mango growers face a serious economic loss every year. Among several such alternatives, the preharvest bagging technique of fruits has been used widely in several fruit crops for attracting skin color and to reduce the incidence of diseases, insect pests, mechanical damages, sunburn of the skin, agrochemical residues on the fruits and bird damages [3,4,5,6,7]. However, recently fruit bagging technology is commercially going to be promoted in mango orchards of different location in Bangladesh.…”

Pre-harvest Fruit Bagging Enhanced Quality and Shelf-life of Mango (Mangifera indica L.) cv. Amrapali

“…Several good agricultural practices are becoming popular throughout the world for preventing the losses of fruits caused by both biotic and abiotic factors [4]. Among several such alternatives, the pre-harvest fruit bagging technique has been adopted widely in several fruit crops to improve skin color in the same time, to reduce the incidence of diseases, insect pests, mechanical damages, sunburn of the skin, agrochemical residues on the fruits, and bird damages [5,6,7,8,9,10,11,12,13]. Therefore, the present study has been undertaken.…”

Influence of Pre-Harvest Bagging on Fruit Quality of Mango (Mangifera indica L.) cv. Langra

“…Among several such alternatives, Pre-harvest paper bagging is a physical protection method which not only improves the visual quality of fruit by promoting skin coloration and reducing blemishes, but can also change the microenvironment for fruit development, which can have several beneficial effects on internal fruit quality. Pre-harvest bagging of fruit can also reduce the incidence of disease, insect pest and/or mechanical damage, sunburn of the skin, fruit cracking, agrochemical residues on the fruit, and bird damage [3,4,5,6,7,8,9,10]. The aim of this study was undertaken to control mango pests and diseases as well as to improve the fruit quality of mango through bagging technology.…”
