The objective of this study was to analyze the influence of different types and fertilizer application in the development of mini tomatoes seedlings (Lycopersicum esculentum var. Cerasiforme) placed in biodegradable foamed recipients, manufactured with sugarcane fibers, cassava starch and plasticizer. Stalk diameters, seedling heights, quantity of leaves and the physical integrity of packaging at 30, 60 and 90 days after sowing were evaluated. The tomato productivity was significantly increased by the use of fertilizer incorporated into the substrate. This significance was not observed for the seedlings with fertilizer incorporated into the packaging ??? although, in general, these are higher and have more leaves when compared to those without fertilizer. All packaging remained intact up to 30 days after sowing. From this period on, as expected, the biodegradable packaging began to decompose. However, at 60 days, the tomato seedlings remained intact and suitable for planting in the soil.
