1. Spatial variability of soil physical attributes in integrated production systems in the Amazon region
Resumo: O objetivo deste trabalho foi analisar a variabilidade espacial de atributos físicos do solo em sistemas de produção integrada e a sua relação com o crescimento e a produtividade da cultura de milho (Zea mays) consorciada com braquiária (Urochloa brizantha). O experimento foi conduzido em sistema de integração lavoura-pecuária (ILP) e em sis

2. Growth promotion of Guinea grass by diazotrophic bacteria1
RESUMO A espécie Panicum maximum cv. Mombaça é uma forrageira adaptada às diversas condições edafoclimáticas encontradas no Brasil; no entanto, necessita de altas doses de fertilizantes nitrogenados para garantir altas produtividades. Objetivou-se avaliar o efeito da inoculação com estirpes de bactérias diazotróficas associativas nas característi

3. Productive performance and quantitative carcass traits of lambs fed saccharine sorghum silage
Resumo: O objetivo deste trabalho foi avaliar o desempenho produtivo e as características da carcaça de cordeiros alimentados com silagens de diferentes tipos de sorgo e milho. Foram utilizados 32 cordeiros machos, da raça Suffolk. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos (silagens) e oito repetições (animais). Fo

4. Morpho-physiology, yield, and water-use efficiency of Opuntia ficus-indica irrigated with saline water
ABSTRACT. Forage cactus pear is considered a xerophilic plant, so it is adapted to harsh semiarid conditions and is a forage resource of significant importance for animal production in regions that are subject to food shortage and long dry periods. We aimed to evaluate the morphometric and physiologic characteristics and water-use efficiency of ‘Gigante’

5. Forage sorghum-legumes intercropping: effect on growth, yields, nutritional quality and economic returns
ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip int

6. Comparative performance of forage cluster bean accessions as companion crops with sorghum under varied harvesting times
ABSTRACT Harvesting time and type of accession of forage legumes are important factors to determine their performance as companion crops for cereals. The objective of this multi-year field trial was to evaluate different harvesting times of forage cluster bean accessions sown as companion crops with forage sorghum under irrigated conditions. Treatments inclu

7. Cover crop rotations in no-till system: short-term CO2 emissions and soybean yield
ABSTRACT: In addition to improving sustainability in cropping systems, the use of a spring and winter crop rotation system may be a viable option for mitigating soil CO2 emissions (ECO2). This study aimed to determine short-term ECO2 as affected by crop rotations and soil management over one soybean cycle in two no-till experiments, and to assess the soybean

8. USE OF ACTIVE OPTICAL SENSOR IN THE CHARACTERISTICS ANALYSIS OF THE FERTIGATED BRACHIARIA WITH TREATED SEWAGE
ABSTRACT Through the use of remote sensing, the productivity and the nutritional state of the plants can be estimated in relation to the nitrogen doses due to the modification of the canopy reflectance. In this study, values of the normalized difference vegetation index (NDVI) obtained by a terrestrial optical sensor were correlated with productivity and con

9. Biometric and chemical characteristics of sugarcane varieties for use as forage in limiting soil water conditions
ABSTRACT This study aimed to evaluate the biometric and chemical characteristics of five sugarcane varieties (RB 863129, RB 867515, RB 92579, RB 943365, and RB 98710) grown in a semi-arid climate for use as forage. The experiment was designed as randomized blocks, in a 5 × 2 factorial arrangement (five sugarcane varieties and two evaluation times, 407 and 4

10. Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage

11. Genetic parameters of agronomic characters in Panicum maximum hybrids
This study was carried out with the objective of estimating the genetic parameters of agronomic traits in Panicum maximum hybrids. Genotypes obtained from the crosses between the sexual plants S10 and S12 and cultivars Tanzania and Mombasa were evaluated. The design was an incomplete blocks design with two replicates (clones) and 33 blocks. Each block was co

12. Repeatability of agronomic characters in Brachiaria brizantha cultivars
This experiment was carried out with the objectives of determining repeatability coefficients, the number of harvests necessary to increase accuracy and the genotypic stability of yield characteristics in Brachiaria brizantha cultivars in the northeast region of Brazil in the period from July 2009 to March 2011. The experimental design used was completely ra
