This work had the goal to evaluate the influence of PVC film and temperature on the postharvest storage life in four cultivars of okra. The treatments were displayed in randomized complete blocks, in split-split-plot design, where the parcels were the temperatures of 5 and 10°C, and in the sub parcels a 2 (control and PVC wrapped fruits) × 4 (cultivars Amarelinho, Red Velvet, Star of David and Mammoth Spinless) factorial, and in the sub-sub parcels six sampling moments, containing four blocks. Storage at 10°C and wrapping the fruits with PVC film improved the control of fresh mass loss. The film was more efficient in maintaining higher water content in the fruit pericarp at 5 or 10°C. The cultivar Amarelinho lost less fresh mass and maintained higher water content. Fruits stored at 5°C had higher vitamin C content. The cultivars Mammoth Spinless and Star of David showed lower losses of vitamin C. Cultivar Mammoth Spinless had the highest content of chlorophyll and Amarelinho the lowest. In general the development of chilling and browning was higher in fruits without PVC film at 5°C. The cultivar Amarelinho had better postharvest conservation at 10°C and using PVC film. Source

The study aimed to evaluate the agronomic and economic performance of intercropping onion and lettuce on four plant densities of each species. The experiment was set up in completely randomized blocks, with four replications and treatments arranged in a 4 × 4 factorial. Treatments resulted from a combination of four (100, 80, 60, and 40% of recommended plant densities in monoculture) plant densities for both lettuce and onion. Intercropping did not affect the agronomic performance of onion or lettuce. Higher plant densities (100% for both vegetables) resulted in higher lettuce and onion yields. The best economic results were observed using (a) onion at 80% of plant density combined with lettuce at 40 and 100% and (b) onion at 100% and lettuce at all densities (40 to 100%). Source
