1 RESUMO
O presente estudo avaliou o uso de hidrogel reutilizado de fraldas descartáveis na produção de mudas de Sabiá (Mimosa caesalpiniifolia Benth), espécie nativa da caatinga. O objetivo foi avaliar seu efeito sobre a altura e diâmetro das plantas durante quatro meses. O experimento foi realizado no Instituto Federal de Educação, Ciência e Tecnologia do Ceará, Campus Acopiara, utilizando diferentes dosagens de hidrogel (2 g, 4 g e 6 g) em comparação a um tratamento controle. Os resultados mostraram que doses elevadas de hidrogel prejudicaram o crescimento das mudas, enquanto o tratamento com 2 g não superou o controle indicando que, embora a retenção de água seja benéfica o excesso pode levar a problemas que afetam o desenvolvimento das plantas em ambientes como o semiárido. Os achados sugerem a necessidade de novas pesquisas para determinar a dosagem ideal de hidrogel que favoreça o desenvolvimento das plantas.
Palavras-chave: crescimento, polímeros, semiárido, escassez hídrica.

EFFECT OF REUSED DIAPER HYDROGEL ON THE DIAMETER AND HEIGHT OF SEEDLINGS OF SABIÁ
2 ABSTRACT
The present study evaluated the use of reused hydrogels from disposable diapers in the production of seedlings of thrush (Mimosa caesalpiniifolia Benth.), a species native to the caatinga. The objective of this study was to evaluate its effect on the height and diameter of plants over four months. The experiment was carried out at the Federal Institute of Education, Science and Technology of Ceará, Campus Acopiara, using different dosages of hydrogel (2 g, 4 g and 6 g) compared with a control treatment. The results revealed that high doses of hydrogel inhibited seedling growth, whereas the 2 g treatment did not surpass the control, indicating that although water retention is beneficial, excess water can lead to problems that affect plant development in environments such as semiarid areas. These findings suggest the need for further research to determine the ideal dosage of hydrogel that favors plant development.
Keywords: growth, polymers, semi-arid, water scarcity.
