| Abstract: The objective of this work was to evaluate soil water dynamics in areas cultivated with forage cactus clones and to determine how environmental conditions and crop growth affect evapotranspiration. The study was conducted in the municipality of Serra Talhada, in the state of Pernambuco, Brazil. Crop growth was monitored through changes in the cladode area index (CAI) and through the soil cover fraction, calculated at the end of the cycle. Real evapotranspiration (ET) of the three evaluated clones was obtained as the residual term in the soil water balance method. No difference was observed between soil water balance components, even though the evaluated clones were of different genus and had different CAI increments. Accumulated ET was of 1,173... |

| O objetivo deste trabalho foi avaliar as correlações do índice de área do cladódio com características morfogênicas e produtivas da palma forrageira (Nopalea sp. e Opuntia sp.). Foram avaliados três clones de palma forrageira, em condições de sequeiro: IPA Sertânia, Miúda e Orelha de Elefante Mexicana. Dados morfológicos dos cladódios e da planta, índice de área do cladódio e biomassa acumulada foram obtidos na ocasião da colheita. A relação entre os dados coletados foi avaliada por meio da análise de trilha, após a aplicação da matriz de correlação de Pearson e do teste de multicolinearidade. Foram observadas maiores correlações das características morfogênicas com o rendimento da cultura do que com o índice de área do cladódio, com R2 entre 0,5930 e... |

| ABSTRACT Cultivation using brackish waters can result in nutritional and metabolic imbalances in several plant species, consequently reducing the production of dry matter (DM) and accumulation of toxic ions (Na+ and/or Cl-) in plants. We evaluated the DM production, and nutrient and inorganic solute (Na+ and Cl-) content in green onion plants (cv. Todo Ano Evergreen - Nebuka) under different levels of nutrient solution salinity in combination with circulation frequencies of this solution. Two experiments were conducted in a hydroponic system, using a completely randomized design, in a 6 × 2 factorial scheme, with five replicates: six levels of nutrient solution salinity (1.5, 3.0, 4.5, 6.0, 7.5, and 9.0 dS m-1) and two solution circulation frequencies... |
