1. SPATIAL VARIABILITY OF THE SATURATED HYDRAULIC CONDUCTIVITY OF SOIL IN COCOA FARMING IN RECÔNCAVO BAIANO
RESUMO O cultivo de cacau irrigado abriu espaço para a produção em solos de Tabuleiros Costeiros. Porém, nesta região, a camada coesa formada próxima da superfície, pode ser um fator limitante para sua produção. O conhecimento dos atributos físico-hídricos do solo possibilitará um manejo eficiente da irrigação em solos coesos. Com isso, objetiv

2. Impact and management of diseases in the propagation of fruit plants
Resumo Mudas bem formadas e sadias são o sucesso econômico na fruticultura. A sanidade das mudas deve ser assegurada durante o processo de produção, evitando a morte de plantas e a disseminação de patógenos para novas áreas, tendo como consequência o aumento do custo de produção e a redução da produtividade, podendo determinados patógenos, inv
