| Popis: | Most of the population in developing countries still uses medicinal plants as the main source to meet their medical needs. Field experiments were carried out at tropical environment in Brazil in order to determine the main characteristics of ‘batata-de-purga’ (Operculina macrocarpa L. Urban), cultivated under 5 different levels of irrigation. The crop was cultivated with and without shading, using a plastic cover. The irrigation treatments were based on reference evapotranspiration (ETo): T1 = 25% ETo; T2 = 50% ETo; T3 = 75% ETo; T4 = 100% ETo; and T5= 125% ETo. Irrigation was performed in interval of three days and the applied water volume was based on treatment T4. The daily values of ETo were determined according to the method of Penman-Monteith. The results indicated that the growth variables of ‘batata-de-purga’ production components were strongly influenced by both the applied water levels and the cultivation conditions. Key words: Evapotranspiration, irrigation water use efficiency, yield. |
