| O presente trabalho teve por objetivo avaliar o desempenho do milho para produção de silagem e grãos, cultivado em diferentes sistemas e adubações. O delineamento experimental adotado foi de blocos inteiramente casualizados, em esquema fatorial 2 x 3, composto por dois sistemas de cultivo (sucessão e rotação de culturas) e três fontes de adubação (orgânica, mineral e organomineral), com quatro repetições. Para produção de silagem de planta inteira, os sistemas e as adubações não diferiram estatisticamente entre si (p < 0,05). Para produção de silagem de grão úmido, o sistema em sucessão e a adubação mineral mostraram-se superiores aos demais, produzindo 10.823 e 10.815 kg ha-1, respectivamente, não incrementando, contudo, qualidade à silagem. Já na... |

| Inappropriate soil management practices that have been applied in the Yafacuy River basin, Venezuela, have led to the loss of soil organic matter and crop productivity. The incorporation of composted organic residues has been suggested as an alternative management practice in order to increase organic matter (OM) content and crop yield in these soils. The objective of this study was to determine the effects of different application fates of an organic fertilizer obtained from sugarcane industry wastes, filter cake and bagasse with or without inorganic fertilizers, on microbial biomass carbon (MB-C), soil organic carbon (SOC), maize (Zea mays L.) yield and N, P, K content in the maize leaves, in Yafacuy River basin. The experiments were established in an... |

| Organic fertilization provides low cost, supplemental nutrition for plant production. This study aimed to determine the best source and dose of organic fertilizer on the growth of physic nut (Jatropha curcas L.), a potential biodiesel producer. Physic nut seedlings were transplanted to 18 dm³ black plastic pots filled with soil mixed with four sources of organic fertilizer (chicken, fish, cattle manure or urban waste compost) at four dose levels (50, 100, 200 or 400 L m-3). Fertilized and control (no fertilization) plants were grown under shadehouse conditions and morphological plant features were assessed at 30, 60, 90 and 120 days after transplanting. Doses higher than 100 L m-3 of poultry manure mixed with claysoil should be avoided. The use of other... |

| ABSTRACT: The successive application of pig slurry to pastures is a common practice in southern Brazil, serving as a method of waste disposal as well as an important alternative to chemical fertilization. Although there are economic benefits to the use of manure as fertilizer, it may be associated with environmental hazards and cause changes to composition and activity of soil fauna. This study aimed to study the effects of pig slurry on the soil biota of pastures. Composition and biological activity of pastures where manure was applied successively for 2 years (A2) and 14 years (A14) were evaluated, and native forest (NF) was analyzed as a reference area. Successive application of pig slurry to the soil changed its biological characteristics according to... |

| El chile manzano (Capsicum pubescens R. y P.) es originario de Perú y Bolivia, fue introducido a México a principios del siglo XX. Este tipo de chile se produce a altitudes de 1700 a 2500 m. En La Sierra Norte de Puebla la producción de este cultivo se hace a nivel de traspatio, con manejo insuficiente de fertilización y control de plagas. Como parte de una propuesta para mejorar el manejo de este cultivo, y hacer uso de los recursos disponibles en la región, que también se dedica a la ganadería para producción de leche, se compararon dos sistemas de producción, uno con fertilización orgánica y otro con fertilización química, en rendimiento y la calidad del fruto de chile. En el sistema con fertilización química la dosis 200-100-200 (NPK), se fracciono en... |

| ABSTRACT Several research lines are required to ensure a proper disposal of sewage sludge in Brazil; among them, we may highlight agricultural use. In this sense, this study aimed at assessing the effect of exchanging nitrogen sourcing via conventional fertilization (chemical) with growing doses of composted sewage sludge (CSS) on wheat crop performance. The experiment was performed in a completely randomized design with seven treatments and ten replications, being defined as T0 (control – without fertilization); T1 (100% mineral fertilization); T2 (50% mineral + 50% CSS); T3, T4, T5, and T6 (100, 150, 200, and 250% nitrogen fertilizing from CSS). Results showed that the use of CSS increased wheat production and development, therefore enhancing its... |

| The present concern about environmental degradation has produced a renewed interest in organic fertilizers, such as animal manures. In addition, the soil organic matter conservation is one of the most important limiting factors for sustainability development in semiarid regions. In a previous experiment, carried out to evaluate the direct effects of application of manure rates in corn, positive effects of this fertilization were observed on green ear yield and grain yield. It was also verified that manure increased water retention and availability, and phosphorus, potassium, and sodium contents in the soil layer from 0-20 cm, but did not influence pH, calcium, organic matter contents and the sum of bases. The objective of this work was to evaluate the... |
