摘要: The objective of this work was to evaluate different types weed management in passion fruit culture under chemical and organic fertilization. experimental design randomized blocks with 15 treatments, arranged a splip-splot design, four repetitions containing 10 plants each. treatments consisted three fertilization (organic, + organic) five each subplot (hand-hoeing, without hand-hoeing, diuron (pre-planting) glyphosate (postemergence), MSMA (postemergence) (diuron paraquat) (postemergence). Diuron applied pre-planting induced phytotoxicity symptom the leaves around 20 26 days after planting (DAP). However, it more evident undergoing associated provided highest productivity. For cultivation using fertilization, hand-hoeing promoted On other hand, under, crop production control were observed treatment (pre) (post).
