ABSTRACT.- Hostipastoral systems in small farming units that integrate horticulture crops, as main cash crop, with sheep/cattle raising on cultivated forage, in Uruguay, present physical restrains to crops because of high consistency and compaction of the vertic soils and unique tillage requirements. The objective of this study was to evaluate the effect of different hortipastoral systems on soil organic matter, aggregation, porosity, permeability and onion yield during a cropping year in onion-forage hortipastoral systems.

ABSTRACT. - Context. For extensive production systems, crossbreeding may be a tool that can be used to achieve production of quality wool and meat to suit market specifications. Aims. To evaluate two levels of crossbreeding of Dohne Merino (DM) sires with Corriedale (C) ewes on productive and reproductive traits of the crossbreed progeny in comparison with purebred C progeny. Methods. Two studies using three genotypes ? 100% C (100C), 50% DM × 50% C (50DM) and 75% DM × 25% C (75DM) ? were carried out. In Study 1, growth, wool production and nematode resistance were evaluated (n = 1652).
