Resumen:
The present work aimed to evaluate mays cropping on wetland soils in
rotation with the irrigated rice and compare the effects of different irrigation methods and
soil preparation systems on mays and yield. An experiment was carried out from
december/95 to april/96, on the experimental station of Bom Intento, Boa Vista-Roraima in
geli slightly humid Tb alic, wetland soil.The BR 106 cultivar was tested under furrow and
sprinkler irrigation, and two kind of soil preparation systems, as follows: plough grid +
leveller grid and plough grid + aiveca plough + leveller grid. The experiment design
consisted of a split plot on a randomized blocks design, with four replications.The soil
prepared by grid + aiveca plough + leveller grid resulted in a height plants, compared to
the average obtained in the soil prepared with grids only. On the other hand sprinkler
irrigation proved, 100 grain mays wheight, grain number and higher yield (5.329,7 kg/ha).
