Assessing harvesting and postharvest handlingpractices of Strychnos cocculoides fruitin the Kavango West Region of Namibia

[摘要] ENGLISH ABSTRACT: Traditional harvesting methods used by rural people to harvest indigenous fruit remain a challenge in rural communities. Such methods lead to post harvest losses of fruit. This study was conducted in Ncuncuni Constituency of Kavango West Region; Namibia. It focused mainly on two villages namely, Kaguni and Mile 20. The study sought to assess harvesting and postharvest handling practices of Strychnos cocculoides. Specifically the study identified existing harvesting and postharvest handling practices. It assessed the level of postharvest losses of S. cocculoides fruit at different handling practices and maturity stages. It further assessed fruit quality in terms of Total Soluble Solids (TSS), taste, size, and weight.Data was collected between September and October 2015 by means of semi structured and a consumer preferences questionnaire. Focus group discussion and direct observations were also employed during data collection. A total of 160 harvesters and 150 consumers from bothstudy sites were interviewed. The findings indicated the fruit are harvested between June and December mainly by women and children. The fruit were harvested in crop fields andcommunal forests mainly for consumption and income generation. Fruit were harvested fully mature, half mature and just mature. Climbing the tree and using the stick method to dislodge the fruit to the ground was the two methods used for harvesting. From the field, the fruit weretransported to homesteads and markets with a vehicle, donkey/oxen cart, head load or public trucks. The fruit were stored in traditional huts, loose on the ground or in gunny bags in the shade of trees. The fruit were sold next to the main road in both study sites as well as in urbanareas within Namibia.The maturity stages at which the fruit were harvested had no significant effect on fruit weight, size and TSS as well as taste in terms of consumer preferences. Poor harvesting andpost-harvest handling practices were observed in both study sites. Fruit damage due to cracks bruises, rotting during harvesting, transportation, storage and marketing was the main challenges caused by poor harvesting and handling practices. Fruit were reported to be deteriorating resulting in short shelf life. The poor harvesting handling practices can have a negative impact on the income generated from the sale of the harvested fruit.
