ABSTRACT Corn intercropped with Urochloa brizantha (Syn, Brachiaria brizantha) has been indicated as a suitable alternative management practice for rational land use in crop-livestock production systems in the Cerrado region of Brazil. An experiment was carried out in Maracaju, MS, Brazil to evaluate the effect of sequences of soybean/second-crop corn systems intercropped with Urochloa brizantha and the effects of forms of nitrogen on soil chemical and physical properties. A randomized block experimental design was used with four replications; treatments were […]

Wheat tiller number and survival and ear and grain production as affected by nitrogen supply were studied in cv.Embrapa 16 in three field experiments at Estação Experimental Agronômica (UFRGS), in Eldorado do Sul, RS, during 1995, 1997 and 1998.The first-year treatment consisted in applying 40kgha-1 of N in different plant stages (emergence to 5th leaf stage), followed or not by an extra N-supply at the 7th leaf stage. In 1997 and 1998, different N rates were applied at plant emergence, […]
