Fertilizer distribution mechanisms and side dress nitrogen fertilization in upland rice under no-tillage system Scientia Agricola
Crusciol,Carlos Alexandre Costa; Costa,André de Moraes; Borghi,Émerson; Castro,Gustavo Spadotti Amaral; Fernandes,Dirceu Maximino.
Some crops have shown not to adapt to the no-tillage system (NTS) as a consequence of the compaction of the superficial soil layer. In a certain way, the mechanism used in seeders to open furrows for the deposition of fertilizers can have great importance in facilitating root penetration. This study was carried out to evaluate the influence of two fertilizer distribution mechanisms and N fertilization in upland rice (Oryza sativa) under NTS. The experiment was carried out in the growing seasons 2001/2002 and 2002/2003, in Botucatu, state of São Paulo, Brazil. A completely randomized block design was applied, with subdivided plots and four replications. Main plots consisted of two furrow opening mechanisms (furrow opener and double disk). Subplots consisted...
