The aim of this study was to evaluate the effect mulching with dry leaves babassu palm (Orbygnia phalerata Mart.) on germination weed seed bank rice tiller number and grain yield maize in Maranhão state, northeastern Brazil. In field experimental design a split plot randomized complete block 15 replications. Rice, intercropped were allocated main plots treatments unprocessed whole dried (0 23 t ha-1) subplots. Germination assessed after crop harvest greenhouse by means collection three soil samples per subplot (n = 270) an open metal device 25 cm length x 16 width 3 height as sampling unit. Soil placed aluminum trays irrigated daily. germinated species identified counted every fifteen days. results showed that can reduce up 55% promoted significant increase from 63 95 m-2, 1,077 2,251 kg ha-1 1,137 2,293 ha-1. Therefore, be recommended for control smallholder farming crops.
