Semeadura direta de forrageiras de estação fria em campo natural com aplicação de herbicidas:I. Produção de forragem e contribuição relativa das espécies. [No-till seeding of cool season forages on native pasture with herbicides application:I. Forage yield and relative contribution of plant species].
RESUMO.- Os campos naturais apresentam estacionalidade na sua produção forrageira, a qual pode ser atenuada com a introdução de espécies de estação fria através de semeadura direta, aumentando a produção forrageira no inverno. Durante quatro anos, conduziu-se um experimento de semeadura direta de forragem de inverno, sobre campo nativo, em um Argissolo Vermelho-Amarelo, de textura superficial arenosa do norte do Uruguai. .-.-.-.-.-.-.-.-. ABSTRACT.- Natural grasslands have great seasonal fluctuation of forage production.

Supplement feed efficiency of growing beef cattle grazing native Campos grasslands during winter: a collated analysis.
Supplementing growing cattle grazing native subtropical Campos grasslands during winter improves the low, even negative, average daily weight gain (ADG) typical of extensive animal production systems in Uruguay. Nonetheless, to render the practice profitable, it is crucial to control supplement feed efficiency (SFE), that is, the difference in ADG between supplemented and control animals (ADGchng) per unit of supplement dry matter (DM) intake. Little has been studied specifically on how SFE varies in these systems.

Effect of sowing density on the productivity of a native grassland restored with Bromus auleticus. [Special Issue 25 Years Agrociencia]
High stocking rate livestock management has determined the decline of native species of high forage value as Bromus auleticus Trin ex Nees in the Campos region of the Rio de la Plata grasslands. The species has some agronomic and ecological characteristics that define it as of high potential to be reintroduced in degraded natural grasslands. However, Bromus auleticus has not been sufficiently described, since commercial seeds and information regarding the establishment phase are scarce.
