Research completed from 2010 to 2012 evaluated the role of storage conditions in preserving produce quality for fresh market. Pomegranate (Punica granatum L.) fruit from Ponder Farm (PF) in 2010, 2011 and Alma Farm (AF) in 2011 were stored in CA (Controlled Atmosphere storage; 5% CO2 + 3% O2; 5oC, 90%-95% RH) and RA (Regular Air storage; 5oC, 90%-95% RH) for three months. Fruit had better quality and lesser deterioration (disease, injury and storage disorders) when stored in CA compared to RA based on physical and physiochemical quality attributes. Kale (Brassica oleracea var. acephala) leaves of two cultivars (Red Russian and Konavale 2) were studied for effect of storage temperature (5oC and 18oC) and bagging (bagging or no bagging) on leaf quality. Leaf were evaluated for weight loss, change in chlorophyll index and leaf yellowing. Kale leaves stored at low temperature (5oC) in bags maintained best quality for longest period of time.
