Potencial de água na folha e produção da tangerina murcote conduzida sob diferentes condições de manejo de irrigação.

Abstract

The crop of “murcote” tangerine was irrigated with three differents kinds of sprays providing three wetting areas and four irrigated depth of application and one not irrigated control. Predawn and between 11 and 12 hours leaf water potential were evaluated. The number of fruits per plant was obtained in the harvesting time with the determination of average weigth of fruits from each plot. The data analysis indicated the leaf water potential decrease with the reduction of irrigation depth, beeing lower in the not irrigated control plot. In the wetting areas 1 and 2, the analysis of variance indicated significance for irrigation treatment for the number of fruits per plant, average weigth per fruit and yield. The results are preliminary once this is the first yield .
