The effects of inorganic fertilizers and three green manure legumes (Canavalia brasiliensis, Mucuna aterrima, and Tephrosia candida) sown at the wet season and subsequently incorporated into the soil, were measured on subsequent wet season maize crop between 1988 and 1992 at the Cerrado Research Center, Brazil. Maize responded significantly (P<0.05) to fertilizer N over the 4-year study period, the highest yield being obtained at 150 kg N ha1. A significant (P<0.05) response to leguminous green manure (LGM) was also obtained There was no interaction between fertilizer N and LGM. Canavalia, mucuna, and tephrosia increased the yield of maize by 1700, 960, and 1250 kg ha1 respectively, when no fertilizer N was added. This was equivalent to 50, 35, and 40 kg ha1 of fertilizer N. However, while canavalia proved to be the most appropriate legume at one location, Planaltina, the choice of LGM may vary depending upon the severity of the dry season at other locations. |
