Abstract/ Executive Summary:

An experiment was conducted to improve the postharvest practices and minimize the postharvest losses of brinjal (Solanum melongena) during January to February 2012. Fresh brinjal fruits were collected from the farmer’s field and treated with 200 ppm NaOCl, wash with clean water or left untreated control and packed in bamboo basket, 0.5% perforated polyethylene bag, plastic crate or Kept without packaging. Minimum physiological loss in weight and less disease incidence was recorded 9.14% and 4.31% for brinjal when washed with chlorine and packed in perforated polyethylene bag. Both treated and non-treated brinjal carrying into plastic crate were found less physical damage of 1.53% compared to other packaging techniques. Maximum weight loss of 53.56% and disease incidence (15.41%) were recorded in brinjal under control treatment. The highest storage life of 14 days was recorded for the brinjal treated with chlorine and packed in perforated polyethylene bag compared to others.

Location: Gazipur

Start Date: 00-01-2012

End Date: 00-02-2012

Program Area: Postharvest and Agro-processing

Commodity:

Objectives:

To improve the present postharvest practices for minimizing the postharvest losses of brinjal.

Methodology:

Brinjal fruits were harvested from the farmers’ field of Jessore district. The fresh brinjals were treated with 200 ppm NaOCl, wash with clean water or left untreated control and packed in bamboo basket, 0.5% perforated polyethylene bag, plastic crate or Kept without packaging. The fruits were then transported to the laboratory of Postharvest Technology section, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. The experiment was laid out in Completely Randomized Designed with three replications. Data on physical damage, physiological weight loss, disease incidence and storage life were recorded.

Budget: 25000/

Total Budget (Tk.) : 25000/

Achievement/Findings:

Both treated and untreated brinjal carrying into plastic crates were found less physical damage of 1.53% compared to other packaging techniques. The lowest physiological loss in weight and less disease incidence were recorded 9.14% and 4.31%, respectively when they treated with 200 ppm NaOCl and packed in 0.5% perforated polyethylene bag. In contrast, the maximum PLW (53.56%) and disease incidence (15.41%) were recorded in control treatment without packaging during 16 days storage in laboratory. The highest storage life of brinjal was recorded 14 days which treated with 200 ppm NaOCl and packed in 0.5% perforated polyethylene bag compared to others.
