RESUMO:O objetivo aqui proposto foi demostrar a experiência da produção e consumo de hortaliças no lar dos idosos localizado em Cruz das Almas, BA. Metodologicamente, foi desenvolvida uma pesquisa de campo, com entrevistas semiestruturadas. Anterior a este processo foi construída a horta. Os principais resultados apontaram que os alimentos produzidos além de representar acesso ao consumo de alimentos livres de agroquímicos, que proporcionou segurança alimentar e nutricional, retrataram ainda histórias de vidas dos internos, as lembranças familiares, à memória de um tempo que desenvolvia atividades no campo. E assim, com fortes referências da sua identidade, muitas das quais, pautadas em questões subjetivas e simbólicas, aproveitando sua bagagem cultural no território urbano.Palavras-chave: referências identitárias, terceira idade, produção agroecológica. ABSTRACT:The objective here was to demonstrate the experience of the production and consumption of vegetables in the home of the elderly located in Cruz das Almas, BA. Methodologically, a field research was developed, with semi-structured interviews. Prior to this process the vegetable garden was built. The main results pointed out that the food produced besides representing access to the consumption of food free of agrochemicals, which provided food and nutritional security, also portrayed histories of the inmates' lives, the familiar memories, the memory of a time that developed activities in the field. And so, with strong references of their identity, many of them, based on subjective and symbolic issues, taking advantage of their cultural baggage in the urban territory.Keywords: identity references, third age, agroecological production.

The knowledge of water consumption and the efficiency of water use by crops is extremely important in the elaboration of agronomic and hydraulic projects of hydroponic systems. Thus, the present study determined the water consumption and water use efficiency of ‘Biquinho’ pepper cultivated in the hydroponic system using seven levels of electrical conductivity of the nutrient solution (ECsol) of 2.70, 3.64, 4.58, 5.28, 6.09, 6.90, and 7.77 dS m-1 and six replicates in randomized blocks. The hydroponic system used was the Nutrient Film Technique (NFT). The water consumption per plant was determined at an interval of ten days in the crop cycle (120 days after transplanting). The maximum mean daily water consumption was equal to 5.88 L plant-1 during the period 111-120 DAT, for ECsol of 4.58 dS m-1. The maximum water consumption for the crop cycle (120 DAT) was 275.66 L per plant for an estimated ECsol = 4.11 dS m-1. The highest water use efficiency (WUE), based on the total production of fruit fresh mass (ripe and unripe fruits) of ‘Biquinho’ pepper was 10.84 kg m-3 up to an estimated ECsol of 5.18 dS m-1, with an exponential reduction thereafter. The salinity of the nutrient solution, biomass production, and evapotranspiration are factors that influence the most water consumption of ‘Biquinho’ pepper.
