Summary

O desempenho agronômico da berinjeleira foi avaliado em cultivo agroecológico, comparando-se espécies de gramínea e leguminosa perenes para cobertura viva do solo. O experimento foi conduzido no município de Seropédica-RJ, no delineamento de blocos casualizados, com parcelas subdivididas e três repetições. Foram avaliadas as coberturas vivas do solo com amendoim forrageiro (Arachis pintoi), grama batatais (Paspalum notatum) e preparo convencional do solo (controle). Nas subparcelas, foram empregadas doses crescentes de "cama" de aviário, correspondendo a 120, 240, 480 e 720 g planta-1, aplicadas parceladamente durante o ciclo da hortaliça. A viabilidade do uso do amendoim forrageiro como cobertura viva no cultivo da berinjeleira foi demonstrada pelo fato de que os valores obtidos nesse tratamento não diferiram daqueles do preparo convencional do solo para as variáveis avaliadas (produtividade, número e peso médio de frutos). A exceção relaciona-se ao uso do amendoim forrageiro associado à maior dose de adubação orgânica (720 g de "cama" de aviário/planta), que se mostrou superior quando comparado ao preparo convencional do solo. Os valores máximos foram obtidos com as doses de "cama" de aviário estimadas em 600 g planta-1 (60,63 t ha-1) e em 480 g planta-1 (55,80 t ha-1) para amendoim forrageiro e preparo convencional, respectivamente. Em contrapartida, com a grama batatais, mesmo a dose mais elevada de adubação orgânica não possibilitou alcançar máximo rendimento da cultura da berinjeleira, indicando assim competição imposta pela gramínea. Os resultados obtidos indicam viabilidade agronômica do cultivo agroecológico da berinjeleira, na cobertura viva permanente do solo com o amendoim forrageiro. O maior rendimento de berinjela associado à aplicação de "cama" de aviário foi obtido na dose de 600 g planta-1.

Summary translation

Agronomic performance of eggplant was evaluated under organic management, comparing perennial grass and legume species as cover crops. The trial was carried out in Seropédica, Rio de Janeiro state, Brazil, using a randomized block design with a split plot arrangement and three replications. The evaluated treatments in the plots were forage peanut (Arachis pintoi) as cover crop, Bahia grass (Paspalum notatum) as cover crop, and conventional soil tillage (control). Split plot treatments were represented by increasing dosages of poultry litter, corresponding to 120, 240, 480, and 720 g plant-1, which were partitioned through the eggplant cycle. The viability of forage peanut used as living mulch for eggplants was evidenced by the fact that its results did not differ statistically from conventional soil tillage for yield, number of fruits per hectare and average fruit weight of eggplant. The only exception is related to the use of forage peanut associated to the greatest dosis of organic fertilizer (720 g plant-1), which has shown superior results when compared to conventional soil tillage. Maximum values were obtained with poultry litter dosage of 600 g plant-1 (60.63 t ha-1) and 480 g plant-1 (55.80 t ha-1) for forage peanut and soil tillage treatments, respectively. On the other hand, Bahia grass did not allow to reach maximum eggplant yield, even at the highest dosage of poultry litter, indicating competition imposed by the cover crop. The results indicate agronomic feasibility of eggplant grown under agroecological management, with forage peanut as soil cover crop. The highest yield of eggplant was obtained with the use of 600 g plant-1 of poultry litter.
