ABSTRACT.
Enhancing pasture persistence is crucial to achieve more sustainable grass-based animal production systems. Although it is known that persistence of perennial ryegrass is based on a high turnover of tillers during late spring and summer, little is known about other forage species, particularly in subtropical climates. To address this question, this study evaluated survival of grazed tall fescue tillers growing in a subtropical climate. We hypothesized that hard tactical grazing during winter to remove reproductive stems (designated as 'flowering control'), and nitrogen fertilization in spring, would both improve tiller survival over summer, and thus enhance tiller density. This was assessed in two experiments. In both experiments, few tillers appeared during late spring and summer and so tiller density depended on the dynamics of vegetative tillers present in the sward in spring. In Experiment 2, flowering control and nitrogen fertilization both enhanced the survival of that critical tiller cohort, but the effects were not additive. Responses were similar but not statistically significant in Experiment 1, which had a warmer, drier summer and lower overall survival rates. Unlike grasses in temperate environments, persistence of tall fescue in this subtropical site appeared to follow a 'vegetative pathway'; i.e., new tillers were produced largely in autumn, from vegetative tillers that survived the summer.

ABSTRACT.
The strawberry fruit production in Uruguay is mainly dedicated to the internal fresh market but there are some experiences of exportation to regional and off shore countries. The crop is done in the annual hill system without the use of methyl bromide and the mean yield is about 40 t/ha. Main crop areas are located in the Northwest (Salto, 31°S) and in the South (San José, 34°S). The winter and early spring fruit production is obtained in the Northwest area with crops under low and high tunnels using short day cultivars like 'INIA Yvahé', 'INIA Arazá' and 'Earlibrite'. Transplants are locally produced in this area in greenhouse nurseries. The Southern area produces fruit in the spring with open field crops using short day cultivars like 'Camarosa' and 'Camino Real' and in the summer with day neutral cultivars like 'Aromas' and 'Seascape'. Frigo-transplants of the introduced cultivars are imported from Spain and USA. Problems of adaptation to the climatic and agronomic conditions of Uruguay have been observed in the introduced cultivars. This was translated to low yields, low fruit quality and susceptibility to diseases prevalent in the regions of production. For that reason the Strawberry Breeding Project of INIA Uruguay aims to obtain cultivars adapted to the different environments of the country. The products of this breeding project, initiated in 1992, are the cultivars 'INIA Arazá', released in 2002, with high early yield and resistance to anthracnose; 'INIA Yvahé', released in 2004, with early yield and excellent flavor, resistant to anthracnose; 'INIA Guenoa', released in 2007, with high yield, excellent fruit quality, better adapted to high tunnels and resistant to powdery mildew; 'INIA Yvapitá', to be released in 2008 for open field crop, recommended for organic production and processing, resistant to several soil, foliage and fruit diseases. New selections are in different stages of evaluation. A method of propagation was adjusted to ensure appropriated quality of the transplants. MenosABSTRACT.
