POSTHARVEST MANAGEMENT OF ‘HARIVANGA’ MANGO VARIETY TO INCREASE SHELF LIFE AND QUALITY

Abstract

The study was conducted at the laboratory of the Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from July 2018 to assess the postharvest management of ‘Harivanga’ mango variety to increase shelf life and quality. The popular Mango variety ‘Harivanga’ were used as experimental materials for the study. The experiment comprised of 19 different postharvest practices as treatment and T 1 : Control condition (no postharvest treatments and stored in open condition). T 8 treatment given the highest result and T 8 : Stored in low density perforated polybag after Bavistin dips treatment. Data were recorded on shelf life and different quality parameters and statistically significant differences were observed for different treatments. The highest shelf life (15.67 days) was observed from T 8 treatment, whereas the lowest shelf life (9.00 days) was recorded from T 1 treatment. At 3, 5, 7 and 9 days after harvest (DAH), the highest moisture content (85.44%, 83.36%, 82.18% and 80.14%, respectively) was found from T 8 treatment, whereas the lowest moisture content (81.76%, 80.22%, 78.66% and 75.85%, respectively) was observed from T 1 treatment. At 3, 5, 7 and 9 DAH, the highest total soluble solids (TSS) (16.34%, 20.83%, 23.55% and 26.12%, respectively) was recorded from T 8 treatment, whereas the lowest TSS content (13.02%, 16.82%, 19.46% and 21.55%, respectively) was observed from T 1 treatment. At 5, 7 and 9 days after harvest (DAH), the highest disease incidence (33.33%, 58.33% and 100.00%, respectively) was recorded from T 1 treatment and the lowest disease incidence (0.00%, 0.00% and 8.33%, respectively) was observed from T 8 and T 9 treatments. So, consideration of shelf life and quality treatment T 8 as stored in polybag after Bavistin dips treatment were superior on other treatment for ‘Harivanga’ mango.
