Fig. 5: Quantity and quality losses associated with storage and packaging of roots and tubers, fruits and vegetables.

a, Storage structures for potato and storage protectants in yam. b, Packaging for citrus and storage protectants in citrus and mango. c, Storage structures for onion and packaging for tomato. The mean percentage quantity loss (blue bars) and quality loss (red bars) and 95% CIs for the different interventions are listed. For each crop and intervention combination, the first n value indicates the number of examples of quantity loss data, while the second n refers to the quality loss data. The loss levels are dependent on numerous factors, including the conditions during the study, which can result in high heterogeneity between studies. The loss levels for each intervention need to be interpreted with caution, particularly where the n value is low. RPC, returnable plastic crates.
