Tomatoes are a highlight in the organic vegetables production, but in order to cultivate them, there is a lack of information on cultivars adapted to the organic system. The objective of this study was to evaluate the productive performance and to characterize the quality attributed to tomato fruits under the organic production system. The experiment was conducted in field, on an agroecological farm, in the municipality of Verê, Paraná State -Brazil. The experiment consisted on fourteen tomato cultivars, under a randomized complete block design, with four replications. The evaluated traits were the total and commercial fruit production, total and commercial number of fruits, mass and average diameter of commercial fruits and physicochemical quality traits (firmness, pH, color (L*, C and h°), soluble solids (SS), titratable acidity (TA), and the ratio of SS/TA). Considering together production traits and fruit quality aspects, the cultivars Netuno, Aguamiel, and Cordilheira can be considered the best choices, having potential to be recommended for organic production system.

ResumoCom a necessidade de buscar alternativas para a produção de um alimento mais saudável e com baixo nível de toxicologia tanto para as pessoas como para o meio ambiente. As chamadas caldas e fertilizantes orgânicos vem com esse propósito, na qual são utilizadas na agricultura orgânica. Com este intuito as oficinas objetivaram levar aos agricultores técnicas de preparo e uso da calda bordalesa e sulfocálcica para o controle de insetos e doenças, bem como a produção de fertilizante orgânico, por meio do processo de compostagem. Realizada em assentamentos rurais no município de Itapiúna no Ceará para agricultores rurais, levou informações que podem utilizar tranquilamente em suas propriedades, principalmente por se tratar de fácil execução e com baixo custo, tanto as caldas como a compostagem, houve grande interesse pela aprendizagem por parte dos agricultores. Palavras-chave: Calda bordalesa. Calda sulfocálcica. Compostagem. TECHNICAL PREPARATION AND USE OF ALTERNATIVE AND COMPOSTING TAILS AbstractWith the need to find alternatives to the production of healthier food and low level of toxicology for both people and the environment. Calls syrups and organic fertilizers come for this purpose, which are used in organic agriculture. To this end the workshops aimed to lead the preparation techniques farmers and use of Bordeaux mixture and sulfur to control insects and diseases, and the production of organic fertilizer through the composting process. Held in rural settlements in Itapiúna municipality of Ceará for rural farmers, led information that can be used quietly in their properties, especially because it is easy to perform and inexpensive, both tails as composting, there was great interest in part by learning farmers.
