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.

ABSTRACT.
Stem and sheath diseases caused by Sclerotium oryzae Cattaneo (SCL) and Rhizoctonia oryzaesativae Sawada Mordue (ROS) can severely reduce rice (Oryza sativa L.) yield and grain quality. Genetic resistance is the best strategy to control them. Phenotypic selection for resistance is hampered due to a heterogeneous distribution of the inoculum in the soil that generates high environmental variability and decreases genetic gain. To have higher selection accuracy it is necessary to develop phenotyping methods with high repeatability and discriminative power. Comparison of greenhouse methods have been reported for Rhizoctonia solani Kühn, a more invasive pathogen than SCL and ROS, and for SCL, but no such comparisons are reported for ROS. Our study compares five inoculation methods for SCL and ROS to identify the more discriminant and repeatable method and to apply it for high-throughput phenotyping of hundreds of rice lines. A method that uses an agar disc with growing mycelium attached to the base of stems was found to have the best balance between discrimination among genotypes and variability among replicates of the same genotype for both pathogens. This method was used in five greenhouse experiments for phenotyping resistance to SCL and ROS in a population of 641 rice advanced breeding lines. Heritabilities of resistance ranged from 0.36 to 0.71 in these experiments. These findings have a direct application in screening for resistance of rice to SCL and ROS, and in high-throughput phenotyping for mapping loci associated to disease resistance.
