1. 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

2. Crop coefficients of tropical forage crops, single cropped and overseeded with black oat and ryegrass
ABSTRACT: Crop coefficient (Kc) is the ratio between crop evapotranspiration (ETc) and reference evapotranspiration (ETo), representing the phenological effects on crop water consumption. Kc is fundamental to estimating ETc by agrometeorological methods. This research study aimed to determine Kc and ETc values for Guinea grass (Megathyrsus maximus cv. Momba�

3. Performance and grazing behavior of growing goats supplemented with palm tree fruit
ABSTRACT This study aimed to evaluate the performance and ingestive behavior of growing goats grazing on Tanzania guinea grass and fed diets containing 40% carnauba or tucum fruits. Twenty-one male castrated goats were distributed into three groups, one exclusively on pasture and the other two on pasture and fed diet supplemented at the level of 1.5% body we

4. VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES
ABSTRACT One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated. Estimates are advantageous for being practical and able to be used for grazing optimization. This study aimed to evaluate the correlation among growin

5. In vitro study of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation and microbial population
ABSTRACT An in vitro study was carried out to identify the effects of different inclusion levels of postbiotics from Lactobacillus plantarum RG14 on rumen fermentation profiles, gas production kinetics, and microbial population in rumen fluid collected from goats. Postbiotics were added at different levels (0, 0.3, 0.6, 0.9, and 1.2%) and incubated for 72 h

6. Key factors that influence for seasonal production of Guinea grass
ABSTRACT: Climate, soil and management are the main drives for growth and production of tropical pastures. Thus, a better understanding of the effects of these factors and their interactions under climate conditions is required to obtain effective management options. Here, we used data from two field trials to research on climate and management interactions

7. Decomposition and Nutrient Release Dynamics of Shoot Phytomass of Cover Crops in the Recôncavo Baiano
ABSTRACT Evaluating the decomposition dynamics of vegetative residues from cover crops can provide a better understanding of nutrient release, which is fundamental when choosing a species that is adapted to local conditions. The objective of this study was to evaluate the decomposition rates and nutrient release dynamics of the shoot phytomass of different c

8. Autumn Maize Intercropped with Tropical Forages: Crop Residues, Nutrient Cycling, Subsequent Soybean and Soil Quality
ABSTRACT Autumn maize intercropped with tropical forages can raise the amount of crop residues and improve nutrient cycling, favoring subsequent soybean crop. The objective of this study was to evaluate the effect of forms of implementation of intercropping of irrigated autumn maize with tropical forages on yield, decomposition, nutrient accumulation and rel

9. Kinetics of transit and degradation of the fiber from guinea grass silages enriched with waste from soybean pre-cleaning
The objective was to study the kinetics of transit and degradation of the fiber from guinea grass and the waste from soybean pre-cleaning (WSPC), ensiled with different proportions of mass (0, 100, 150, and 200 g WSPC/kg total mass). Four crossbred (Gyr × Holstein), fistulated cattle with an average body mass of 400±50 kg were organized in a 4 × 4 Latin s

10. Sward structure and livestock performance in guinea grass cv: Tanzania pastures managed by rotational stocking strategies
Grazing strategy is a key element in the determination of sward structure, herbage nutritive value and animal performance. We aimed to compare the herbage characteristics and performance of livestock in pastures of Panicum maximum cv. Tanzania managed, using two rotational stocking strategies, which provided either a fixed-length rest period (FRP) of 35 days

11. Production and nutrition of irrigated Tanzania guinea grass in response to nitrogen fertilization
The objective of this study was to evaluate the effects of nitrogen (N) fertilization in the four seasons of the year on forage production, nitrate (NO3) in the sap, total N in the forage and relative chlorophyll index (SPAD reading) in the leaves of irrigated Panicum maximum cv. Tanzania grass, establishing their critical ranges. In addition, we evaluated t

12. Época de aplicación y toxicidad varietal del herbicida amicarbazone en la caña de azúcar, en Veracruz, México
During the 2005 Spring-Summer growing cycle, three experiments were established in Ursulo Galvan, Ver., Mexico, to determine the best time of application of the herbicide amicarbazone in irrigated sugarcane, and the susceptibility of the three main varieties grown in this state to this herbicide. In one experiment, weed control of amicarbazone at 0.7, 1.05 a
