Abstract/ Executive Summary:

A study was conducted in Farm Machinery and Postharvest Process Engineering Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. A base line survey was conducted on vegetable production, sorting, washing, packaging mainly of carrot, red amaranth and brinjal from three vegetable growing districts such as Narsinghdi, Bogra, Jessore, and one major carrot growing area Pabna for developing a mechanical vegetable washing machine. Two upzila from each district were selected considering the primary and secondary markets. The respondents for primary data collection were 71 farmers, 30 pickers and 20 retailers. Washing of vegetables mainly practiced by farmers and pickers and it varied from location to location. Sorting and grading were done either farmers or pickers. In all locations, red amaranth and root crops (carrots and radish) were washed by farmers to get better price. A vegetable washing machine was designed based on the base line information. The capacity of the machine would be 1.0-1.5 ton/h depending on the type of vegetables. The fabrication was going on and expected to complete in the next financial year (2015-16).

Keywords: Washing machine, Vegetable, Survey questionnaire

Location: Farm Machinery and Postharvest Process Engineering Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur.

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Farm Mechanization

Commodity: Farm machineries

Objectives:

a) To design and fabrication of a vegetable washing machine (b) To evaluate the technical and economic performance of the machine (c) To determine the quality of vegetable before and after washing (d) To disseminate of the technology to the relevant stockholder through training, demonstration and workshop

Methodology:

Three vegetable growing districts such as Narsinghdi, Bogra, Jessore, and one major carrot growing area Pabna were selected to collect base line information on vegetable production and washing. Two upzila from each district were selected with the consultation of vegetable scientists of BARI. Sample respondents: Vegetable farmers and traders (Picker and retailer) were the respondents. Sample size: Total 121 respondents were randomly selected for interviewing for base line survey. Primary and secondary markets were taken into consideration. Seventy one farmers, 30 pickers and 20 retailers were interviewed for primary data collection. Preparation of survey questionnaire: Survey questionnaire was developed by incorporating indicators for fulfilling the study objectives. The draft questionnaire was modified through pre-testing in the project areas. Data collection: Primary data was collected from farmers and traders by trained enumerators using structured questionnaire through personal interview. Secondary data was collected and incorporated with primary data. PI and CI continuously monitored the data collection. Physio-chemical parameters of vegetables were determined in FMPE Post harvest laboratory.

Achievement/Findings:

A baseline study was conducted to explore the current status of sorting, washing, and packaging done for different vegetables at farmers and traders level. In Bogra, 100% farmers sorted carrots, red amaranth and brinjal and 87.5%t farmers washed them. In Pabna, 50% farmers sorted and 87% farmers washed carrots. In Narshingdi, 22% farmers washed red amaranth. Twenty two percent farmers sorted and washed brinjal. In Jessore, 66% farmers sorted red amaranth and 100% farmers washed it. In Bogra, fifty percent traders sorted and washed carrots. One percent traders sorted red amaranth and 57% traders washed it. Forty three percent traders sorted and washed brinjal. In Narshingdi, 33% traders sorted and washed red amaranth. Sixty six percent traders sorted brinjal and 28.5% traders washed it. In Jessore, 20% traders sorted and washed carrot. Twenty percent traders sorted and 40% washed brinjal. In all locations, red amaranth and root crops. A vegetable washing machine was designed based on the base line information. The capacity of the machine would be 1.0-1.5 ton/h depending on the type of vegetables. The fabrication is going on and expected to complete in the next financial year (2015-16).
