Abstract/ Executive Summary:

The study was undertaken to determine the profitability and fruit quality of mango using different bagging materials in five Upazilas’ namely: Chapainawabganj Sadar, Shibganj, Bholahat, Nachole and Gomastapur of Chapainawabganj district. Data were collected through interview schedule from randomly selected 100 farmers from July to August 2019. Among different bagging materials used in mango fruit, Brown paper bag was found most effective in several parameters like fruit retention, fruit weight, fruit length, fruit diameter and total sugar percentage. Bagging technology numerically increased the level of mango production per hectare which was 10850 kg and gross return and net return was Tk. 596750 and Tk. 430910 respectively. With higher production and price bagging technology adopters had numerically higher benefit-cost ratio (BCR) was 3.59 than non adopters which were Tk. 330000 and 3.26 respectively. About 60% of the respondents showed high attitude towards fruit bagging as it increases shelf life, reduce pest incidence and overall ecofriendly. Therefore, from the findings of the study it is highly recommended to use fruit bagging in mango production as it is profitable as well as improves fruit quality.

Program Area: Socio-economic and Policy

Non-commodity: Profit

Objectives:

The specific objectives of the study are: i. To determine the effects of different fruit bagging on quality of mango production; ii. To estimate the relative profitability of bagging and non-bagging practices; iii. To assess farmers perception towards fruit bagging.

Methodology:

Keeping in view the objectives of the study Chapainawabganj district of Bangladesh was purposively selected to collect the relevant information for conducting this study because it is considered to be the main mango growing region of Bangladesh. In total 100 farmers, 20 from each of the selected treatment (bagging materials) were selected for the study. Different types of bags have constituted the treatments viz.: T1: Brown paper double-layered bag (BPB) T2: White paper single-layered bag (WPB); T3: Perforated polythene bag (PB); T4: Muslin cloth bag (MCB) and T0: Non-bagged (control). Purposive sampling was employed for selecting mango growers from different treatments. A draft interview schedule taking into account the objectives of the study was prepared and pre-tested on a few respondents of the study area. In the pre-test, attention was given to identify whether any important information is missing in the draft interview schedule. Then if necessary some parts of interview schedule were improved, rearranged and modified to capture the real picture of the study. Thus, the final interview schedule was prepared to solicit information. A combination of descriptive and statistical techniques as demanded by the study was used to achieve the objectives and to get meaningful results. To obtain the objectives three a 5 point Likert-type scale was used with twelve respective statements regarding the predispositions in the respondent’s opinion. Uniformly grown fruits (40 to 50 days after fruit set) were selected for bagging. The sizes of the bags were 25 × 20 cm. Before bagging two perforations (≤ 4 mm diameter) was made for proper ventilation at the bottom of polythene bag and muslin cloth bag. White and brown paper bags were not perforated. The particular bags were wrapped properly at the stalk of each fruit of respective treatments so that it would not fall down as well as there would not be open space. The observations viz. fruit retention (%) and days require for harvesting after bagging were recorded. Four fruits were randomly selected per treatment per replication to record various physical and chemical compositions which were estimated by the following procedures. Length and Diameter of Fruit were measured with the help of digital Vernier caliper and expressed in centimetres (cm).Weight of fruit; pulp and stone were recorded by using electronic balance and expressed in grams (g). 2.1 Chemical composition Citric acid (%): 10g mango pulp was crushed in a mortar and pestle and transferred in a 100 ml volumetric flask. Volume was made up to 100 ml by distilled water. Then the sample was filtered and 10 ml filtrate was taken in a conical flask. The filtrated was titrated against 0.1 N NaOH using phenolphthalein as an indicator. The results were expressed in percent of citric acid (Moffet et al., 2007). 2.2.3 Benefit-cost ratio To assess the profitability level of mango based on bagging technology simple tabular form and Benefit-Cost Ratio (BCR) was checked. BCR of mango was estimated by the ratio of gross return to variable cost and gross return to total cost. So, BCR was defined as: BCR = Gross return / Total Cost The analytical procedures involve the arrangements of the collected data in systematic ways, costing of the input used, quantifying the effect of inputs on yield, etc. the following analytical procedure was followed in the present study.

Achievement/Findings:

Fruit bagging has emerged as a novel technology in practice, which is simple, grower friendly, safe and beneficial for the production of quality mangoes. It is easy and safe practice that protects fruit from diseases and insect pest’s damages, mechanical damage, sunburn of the skin, fruit cracking, agrochemical residues on the fruit and bird damage. If the technology was used, there will be no spot on mango in the bagged ones. Besides, the mango could be protected from all kinds of diseases and pests that will boost the volume of exportable mango. The results of this study clearly demonstrate that it is advisable to use brown paper bag for getting colored fruits i.e., yellow color since white paper bag for retains original color of each variety. Both bags showed their potentiality against major insect-pests and diseases damages. Apart from this, as the market price of the bagged mango is lucrative the growers can sell their produce at high price. Therefore, farmers might be used this technology for commercial mango cultivation to fulfil the demand of quality mango in-country and abroad.
