Resumo: | After rain or irrigation, the soil pores may present a low oxygen content (hypoxia). Soil aeration after irrigation has been used to overcome hypoxia-based problems. This study aimed to investigate the effect of four aeration levels (0, 0.5, 1.0 and 1.5 times the standard volume) applied after irrigation, using a subsurface drip system, at two soil depths (0.15 m and 0.30 m). A randomized block design was used, in a 4 x 2 factorial scheme, with six replications. The yield characteristics assessed were: total fruit mass per plant, average fruit mass and number of fruits per plant. The growth characteristics were root and stem dry mass. The water-use efficiency was also calculated. The results indicated that the highest aeration level, at a depth of 0.30 m, increased the yield by 41.2 %, when compared with plants that received only irrigation, at the same depth. The water-use efficiency was influenced by the soil aeration after irrigation only at the depth of 0.30 m. KEYWORDS: Solanum lycopersicum, air injection into the soil, soil hypoxia. |

KEYWORDS: Solanum lycopersicum, air injection into the soil, soil hypoxia.Após uma chuva ou irrigação, os poros do solo podem apresentar baixo teor de oxigênio (hipóxia). A aeração dos solos após a irrigação tem sido utilizada para superar problemas associados com a hipóxia. Objetivou-se investigar o efeito de quatro níveis de aeração (0; 0,5; 1,0; e 1,5 vezes o volume padrão) aplicados após a irrigação, por meio de sistema de gotejamento subsuperficial, em duas profundidades no solo (0,15 m e 0,30 m). O delineamento experimental foi em blocos casualizados, em esquema fatorial 4 x 2, com seis repetições. As características produtivas avaliadas foram: massa total de frutos por planta, massa média de fruto e número de frutos por planta. As variáveis de crescimento foram: matéria seca de raiz e de caule. A eficiência de utilização da água também foi calculada. Os resultados indicaram que o maior nível de aeração, na profundidade de 0,30 m, aumentou o rendimento em 41,2 %, em comparação às plantas que receberam apenas irrigação, na mesma profundidade. A eficiência de utilização de água foi influenciada pela aeração do solo após a irrigação apenas na profundidade de 0,30 m.
