LIMA, Márcio E. de et al. Eggplant crop in no tillage system under different irrigation depths. Rev. bras. eng. agríc. ambient. [online]. 2012, vol.16, n.6, pp.604-610. ISSN 1807-1929.  https://doi.org/10.1590/S1415-43662012000600003.

This study was carried out in the municipality of Seropédica-RJ, in order to determine, under organic farming and no tillage system, the yield of eggplants under different irrigation depths and cropping systems (intercropped with legumes and alone). The experimental design was in randomized blocks in a split plot design with four replications. The plots were characterized by the treatments corresponding to different water depths (40, 70, 100, 120% ETc), and the sub plots, the intercropping systems with cowpea and eggplant alone. Cropping systems did not influence the final yield of eggplant. However, considering the different irrigation depths, the highest commercial yield (65.41 Mg ha-1) was obtained for a total depth of 690.04 mm (106.8% ETc). The lower applied depth provided lower quality of fruit compared with that observed in the higher depths. The rate of fruit discard was 3 and 14%, respectively, for the higher and lower depths of irrigation.
