| Grapevines grown on sandy soils are subjected to the application of supplemental nitrogen (N); however, there is little information available regarding the impact of these applications on yield, plant nutritional state and must composition. The aim of this study was to evaluate the yield, nutritional state and must composition of grapevines subjected to N fertilization. Cabernet Sauvignon grapevines were subjected to annual applications of 0, 10, 15, 20, 40, 80 and 120 kg N ha-1 in 2008, 2009 and 2010. During the 2008/09, 2009/10 and 2010/11 harvest seasons, leaves were collected during full flowering and when the berries changed color, and the total N content was analyzed. The grape yield and the enological characteristics of the must were evaluated. The... |

| The purpose of this study was to evaluate the nutritional state, yield and composition of peaches on peach trees subjected to the application of organic compost to the soil. This experiment was conducted during the 2008 and 2009 cropping season in an orchard containing Chimarrita cultivars grafted onto Capdeboscq rootstocks and Haplumbrept soils in the municipality of Farroupilha (RS), Brazil. The treatments included 0, 9, 18, 36, 72 and 144 liters of organic compost per plant-1 year-1. The total nutrient contents in the leaves, yield components, yields per plant and hectare and compositions of the fruits were evaluated in 2008 and 2009 soon after harvest and after 30 days of storage. The application of organic compost to the soil increased the yield... |

| O cultivo e a deposição de resíduos de plantas de cobertura em sistema plantio direto podem afetar os atributos químicos do solo e a produção de cebola. O trabalho objetivou avaliar a interferência do cultivo de plantas de cobertura sobre a produção de cebola e sobre os atributos químicos do solo em sistema plantio direto (SPD) agroecológico. O experimento foi conduzido na EPAGRI, em Ituporanga (SC), em um Cambissolo Húmico, nas safras de 2010 e 2011. Em abril, foram implantados os tratamentos: testemunha com vegetação espontânea (T1); cevada (2010)/aveia-preta (2011) (T2); centeio (T3); nabo-forrageiro (T4); centeio + nabo-forrageiro (T5); e cevada (2010)/aveia-preta (2011) + nabo-forrageiro (T6). Aos 60, 80 e 95 dias após a semeadura (DAS) das espécies... |
