Technical report: Postharvest Physiological Deterioration (PPD) tolerance of selected Ugandan cassava varieties. Extending the shelf-life of fresh cassava roots for increased incomes and postharvest losses reduction

The purpose of this study is to screen cassava varieties for their level of tolerance or susceptibility to Postharvest Physiological Deterioration (PPD). Specifically, it aims at collecting varieties of fresh cassava roots preferred by consumers in Ugandan. The study targets the two major fresh cassava supply axes, i.e., Masindi/Kiryandongo and Kyenjojo/Kabarole. Fresh cassava roots were screened for tolerance or susceptibility to PPD. The study also aims at determining the effect of pruning on the deterioration of cassava roots over time and the changes in root biochemistry during storage of both pruned and non-pruned cassava varieties

Training report: capacity building in agronomic practices, waxing and relative humidity storage technologies for shelf-life extension of fresh cassava roots.

This report describes the capacity building process and activities that were done to enable the value chain actors adopt and adapt the pre-and post-harvest practices, and waxing and high relative humidity storage technologies in order to run a successful business enterprise

Technical report: efficacy of pruning, waxing and relative humidity storage in extending shelf-life of fresh cassava roots. Extending the shelf-life of fresh cassava roots for increased incomes and postharvest losses reduction.

The purpose of this study was to evaluate waxing and high relative humidity treatments for efficacy on Postharvest Physiological Deterioration (PPD) reduction. Specifically, it aimed at evaluating effect of waxing and relative humidity storage on PPD, reducing sugars, dry matter content, cyanide content and starch yield as well as acceptability of treated roots

Effectiveness of cassava stem pruning for inducing delay in postharvest physiological deterioration (PPD) of fresh roots

Effectiveness of pruning and waxing in reducing postharvest physiological deterioration in Uganda local cassava varieties.

Cassava ( Manihot esculenta Crantz) roots in the fresh form, are susceptible to postharvest physiological deterioration (PPD), thus reducing their economic value and farmer benefits. The objective of this study was to evaluate the effectiveness of pruning and waxing on fresh root storability among cassava varieties in Uganda. Sixteen cassava plants per variety (TME 14, NASE 14, Nyaraboke, Kirimumpale, and Bukalasa) were pruned seven days before harvest, leaving the rest as unpruned controls. After harvest, roots were divided into two portions and one portion was waxed using food grade wax. Pruning alone reduced PPD of stored roots by 23% at day 14 of storage; and by 19% at day 28 compared with the control. Pruning as a treatment resulted into increased sugar content, ranging 9-30%), and significant (P<0.05) losses in starch yield. Pruning combined with waxing, resulted in a reduction of up to 43% in PPD by day 14, and up to 67 at day 28. Reduction in carbohydrate (starch) was not significant (P>0.05) under the pruning and waxing treatment, which had minor effects on stored root composition. The results indicate that pruning is appropriate for the short-term storage of fresh cassava roots for up to 14 days. Waxing, combined with pruning, is suitable for longer term storage up to 28 days under Uganda conditions.Les racines de manioc ( Manihot esculenta Crantz) \ue0 l\u2019\ue9tat frais sont sensibles \ue0 la d\ue9t\ue9rioration physiologique apr\ue8s la r\ue9colte, r\ue9duisant ainsi leur valeur \ue9conomique et les avantages pour les agriculteurs. L\u2019objectif de cette \ue9tude \ue9tait d\u2019\ue9valuer l\u2019efficacit\ue9 d\u2018 \ue9laguer et de cirer sur la capacit\ue9 de stockage des racines fra\ueeches parmi les vari\ue9t\ue9s de manioc en Ouganda. Seize plants de manioc par vari\ue9t\ue9 (TME 14, NASE 14, Nyaraboke, Kirimumpale et Bukalasa) ont \ue9t\ue9 \ue9lagu\ue9s sept jours avant la r\ue9colte, les autres \ue9tant des t\ue9moins non \ue9lagu\ue9s. Apr\ue8s la r\ue9colte, les racines ont \ue9t\ue9 divis\ue9es en deux parties et une partie a \ue9t\ue9 cir\ue9e avec de la cire de qualit\ue9 alimentaire. L\u2019\ue9lagage seul r\ue9duisait la PPD des racines stock\ue9es de 23% au 14e jour de stockage; et de 19% au 28e jour compar\ue9 au t\ue9moin. L\u2019\ue9lagage en tant que traitement a entra\ueen\ue9 une augmentation de la teneur en sucre (comprise entre 9 et 30%) et une perte significative (P <0,05) du rendement en amidon. La combinaison d\u2018 \ue9laguer et de cirer a entra\ueen\ue9 une r\ue9duction de la PPD de 43% au 14e jour et de 67 ans au 28e jour. La r\ue9duction de la teneur en glucides (amidon) n\u2019\ue9tait pas significative (P> 0,05) dans le cadre des traitements d\u2018 \ue9laguer et de cirer a eu des effets mineurs sur la composition des racines stock\ue9es. Les r\ue9sultats indiquent que l\u2018\ue9laguage convient au stockage \ue0 court terme de racines de manioc fra\ueeches pendant 14 jours au maximum. La combinaison d\u2018 \ue9laguer et de cirer convient au stockage \ue0 long terme jusqu\u2019\ue0 28 jours dans les conditions ougandaises
