1. MORPHOPHYSIOLOGICAL AND NUTRITIONAL BEHAVIOR OF Hymenaea stigonocarpa Mart. ex Hayne (FABACEAE) SEEDLINGS SUBMITTED TO LIMING
RESUMO A calagem é benéfica para as plantas por promover a elevação do pH, neutralização do alumínio tóxico, aumentar o fornecimento de cálcio (Ca²+) e magnésio (Mg²+) e propiciar maior sistema radicular. No entanto, sabe-se que as espécies, principalmente nativas do Cerrado, respondem de formas distintas a essa técnica. Diante do exposto, o ob

5. Gesso agrícola na produção de milho e soja em solo de alta fertilidade e baixa acidez em subsuperfície em plantio direto
There are doubts about the conditions in which a favorable effect of the application of gypsum on the yield of grain crops can be expected. In order to evaluate the influence of gypsum application in the soil chemical attributes, in mineral nutrition of maize (Zea mays L.) and soybean (Glycine max L. Merrill) yield in no-till system, an experiment was carrie

7. AVALIAÇÃO DE CEREAIS DE INVERNO DE DUPLO PROPÓSITO NA DEPRESSÃO CENTRAL DO RIO GRANDE DO SUL / EVALUATION OF DOUBLE PURPOSE WINTER CEREALS AT DEPRESSÃO CENTRAL REGION OF RIO GRANDE DO SUL STATE
In the south of Brazil, one of the largest limitations of cattle activity is the forage lack in the autumn and beginning of winter, causing decrease in milk and meat production. One of the alternatives to minimize this problem is the use of double-purpose winter cereals, that they can supply early green forage and still to produce grains. Then, the objective
