ABSTRACT
Soft texture of stone fruits makes them prone to postharvest losses. Effect of different packaging materials on the texture of fruits also varies for their post-harvest losses. The present study was conducted to evaluate the effect of wooden and cardboard box technologies on post-harvest losses of plum through its marketing channel. Primary data was collected through pre tested questionnaires by proportionate random sampling procedure. Quantitative losses were estimated through percentage method while partial losses were estimated at the wholesale and retail level by price differential method. Multiple regression analysis was employed to find relation between post-harvest losses and different factors at three different stages. Findings of the study revealed the channel of cardboard box technology accounted for post-harvest losses of 10.49% while at farm level, losses were 2.90%, at wholesale level 1.45% and retail level the losses were 6.14%. On the other hand post-harvest losses were 14.24% in wooden box channel; in which 6.10% occurred at farm level, 1.43% at the wholesale level and 6.71% at the retail level. Cardboard box technology has reduced post-harvest losses of plum by 27%. Post-harvest losses were moderate and positively correlated at farm level, weakly and positive related at whole sale level and weak and negatively correlated at retail level. Pre-harvest management, careful handling and harvesting in proper maturity can help in reducing post-harvest losses.
