Factors such as suitable substrate and packaging may increase the shelf life of greenhouse bell pepper. In this study, the greenhouse bell pepper plants grown in the substrates containing 0, 25, 50, 75 and 100% compost tea in hydroponic culture were packaged in two types of film using the modified atmosphere method. Firmness of fruit texture, total soluble solids, pH, titratable acidity, vitamin C, and respiration were measured immediately after harvesting and during storage time with three replications. Then, the data obtained from the above tests were analyzed in a completely randomized design with factorial arrangement (three factors: substrates containing different amounts of compost tea, type of packing material, and storage time). Although the results showed that characteristics of the bell peppers grown on the substrates containing different amounts of compost tea were significantly different (p<0.05) from the substrate without compost, no significant result was obtained as to which percentage of compost tea had the most impact. With regard to storage time, most of the tested characteristics had a decreasing trend, but still laid within the standard ranges. In terms of the type of film, with a slight difference, nanofilm was superior to polyethylene film. As a conclusion, the bell peppers grown on the substrates containing compost tea and packaged in the nanofilms with the modified atmosphere method had acceptable shelf lifes more than one month.
