ABSTRACT.
Soil quality improvement by reducing soil tillage is one tool of sustainable agriculture. Covers crops left on soil surface prevent soil erosion, reduces evapotranspiration and weeds, and improves soil infi ltration; key factors for a successful vegetable production on heavy clay soils. The objective of this research was to evaluate the effect of cover crops plus
ridge tillage on soil water content, soil, physico-chemical and biological properties and on vegetable yield. In 2005 at INIA Las Brujas Research Station was established a fi eld experiment on a Typic Argiudoll soil, of silty clay loam texture with a 3% slope. Conventional treatment with fallow periods was compared with sustainable treatment included
cover crops and minimum tillage. Onion (Allium cepa L.), cabagge (Brassica oleracea, Capitata group), carrot (Daucus carota), sweet potato (Ipomoea batata) and squash (Cucurbita moschata x C. maxima) crops were included in the study. Black oat (Avena strigosa), foxtail millet (Setaria italica) and forage sorghum (Sorghum sudanense x S. bicolor) were the cover crops. Soil water content was measured by time domain refl ectometry on soil surface and by neutron probe in depth. Weed population was evaluated by number and dry weight. Soil biological activity was determined by soil respiration. Weed population and weight of weeds were reduced with minimum tillage as compared to conventional
treatment. Soil water content was higher at certain periods on minimum tillage and biological activity was better on minimum tillage. Vegetable crop yields were similar on both treatments. MenosABSTRACT.

RESUMO: Este trabalho foi desenvolvido com o objetivo de estudar a evolução das características de crescimento e carcaça em função da idade em bovinos da raça Hereford, utilizando modelos não-lineares. Foram utilizados dados de 240 bovinos machos (castrados) da raça Hereford, pertencentes à fazenda Experimental ?La Estanzuela? do INIA, Colonia, Uruguai. As características começaram a ser mensuradas a partir da desmama de animais com aproximadamente seis meses de idade, até o abate (dois anos de idade). As medições de peso foram realizadas a cada 15±3 dias durante todo o período e sem jejum prévio. As mensurações de área de olho de lombo, obtidas por ultrassom, e altura dos animais foram obtidas a cada 90 dias, sendo que as medidas de ultrassom foram tomadas entre a 12a e 13a costelas. Os modelos não-lineares utilizados foram os modelos de Brody, Gompertz, Logístico e Von Bertalanffy. Para as características peso, altura e área de olho de lombo, todos os modelos avaliados atingiram a convergência. Para descrever a evolução dos dados de peso e área de olho de lombo em função da idade, o modelo de Von Bertalanffy foi o mais indicado, e os modelos de Brody e Logístico mostraram o pior ajuste, respectivamente. A evolução da altura dos animais desde o desmame até os dois anos de idade pode ser modelada através de qualquer um dos modelos não-lineares considerados neste estudo. ABSTRACT: The objective of this research was to study the evolution of growth and carcass traits as a function of age in Hereford cattle using nonlinear models. Records from 240 Hereford steers (castrated), belonging to the experimental station ?La Estanzuela? of INIA Uruguay, were utilized. The animals were measured from weaning, approximately at 6 months of age, to slaughter (two years of age). The animals were weighed, without fasting, every 15±3 days throughout the period. The measurements of ribeye loin area (between the 12th and 13th rib) were obtained by ultrasound every 90 days. The height of the animals was obtained every 90 days. The Brody, Gompertz, Logistic and Von Bertalanffy nonlinear models were applied to describe the trajectory of weight, height and ribeye loin area along the age. For height, weight and ribeye loin area, all the models reached the convergence. To describe the
evolution of weight and ribeye loin area, the Von Bertalanffy nonlinear model was the most suitable. For weight and ribeye loin area, the Brody and Logistic nonlinear models have shown the worst fit, respectively. The height trajectory from weaning until two years of age can be modeled by any of the nonlinear models considered in this research.
