Popis: The processes of using the environment and natural resources are increasingly necessary and present in human society. These processes can result in environmental degradation. A recovery strategy for an area that has undergone environmental degradation is revegetation. For the successful establishment of a plant species, the environment must have adequate water and nutritional conditions. The objective of this work was to study the effect of water and nutritional management on the survival, growth, and morphophysiological conditions of plants used in the revegetation of remaining sand and clay extraction areas. The experiment was carried out in a sand loan extraction loan area and a clay loan extraction loan area, both in the coastal region of the municipality of São Mateus, Espírito Santo, Brazil. The experimental design was a randomized block with three replications in a split-plot scheme, using methods of water management in the plots and doses of fertilization (0.000 kg, 0.072 kg, 0.144 kg, 0.288 kg and 0.576 kg) in the pits in the subplots. In both areas, five different species of native plants were used: Aroeira (Schinus terebinthifolius Raddi), Cajá Mirim (Spondias mombin L.), Goiaba do Ipiranga (Psidium cattleianum Sabine), Ingá Mirim (Inga laurina (Sw.) Willd.) and Murta de Restinga (Mouriri guianensis Aubl.). The plants used in the experiment were evaluated for growth, survival, leaf attributes, and chlorophyll a fluorescence. The water management method and the fertilization of the pit had a significant effect on the development of the species evaluated in both areas, acting on the survival rate, growth, morphology and physiology of the plants.
