E-mail: lofeca@cca.ufpb.br 1 RESUMO O trabalho foi realizado em abrigo protegido do CCA/UFPB-Campus III, Areia-PB, com o objetivo de avaliar os efeitos da salinidade da agua de irrigacao e conteudos de agua disponivel do solo sobre o crescimento vegetativo do quiabeiro, Abelmoschus esculentus L. Os tratamentos foram distribuidos em blocos casualizados com tres repeticoes e duas plantas por parcela, arranjados num fatorial 5 x 2, referentes aos valores de salinidade da agua 0,5; 1,5; 3,0; 4,5 e 6,0 dS m -1 e aos niveis de 80 e 100% da agua disponivel do solo. Os resultados evidenciaram que o aumento da salinidade da agua de irrigacao provocou reducoes significativas sobre o crescimento em altura, diâmetro do caule, area foliar e rendimento biologico das raizes, caules e folhas das plantas, independente de serem irrigadas ao nivel de 80 e 100% da agua util ou disponivel do solo. UNITERMOS: salinidade , agua disponivel, Abelmoschus esculentus L. SILVA, A.P., SANTOS, C.J.O., SANTOS, J.B., CAVALVANTE, L.F. VEGETATIVE GROWTH OF OKRA AS FUNCTION OF SALINITY WATER IRRIGATION 2 ABSTRACT This study was carried out in order to evaluate the effects of water salinity irrigation and content of availability water into soil on vegetative growth in okra plants, Abelmoschus esculentus L. The treatments were distributed in randomized blocks in factorial design 5 x 3 referring to salinity water irrigation levels: 0.5; 1.5; 3.0, 4.5 and 6.0 dS m -1 and 80 and 100% of availability water level into soil. The data showed that increment of salinity of water decreased the plants growth in height, stem diameter, leaf area and dry matter production by roots, stems and leaves of plants irrigated with water volums at level of 80 and 100% of water availability into soil. KEYWORDS: saline water, soil water availability, Abelmoschus esculentus L.
