1. Mitigation of Mombasa Grass ( Megathyrsus maximus ) Dependence on Nitrogen Fertilization as a Function of Inoculation with Azospirillum brasilense
ABSTRACT Using biological inputs to improve the efficiency of nitrogen fertilizers represents an alternative for the cultivation of grasses in tropical regions. Azospirillum brasilense is a species of plant growth promoting bacteria widely studied and used in inoculants. Thus, this study aimed to evaluate the performance of Mombasa grass ( Megathyrsus maximu

2. Restoration of abandoned subtropical highland grasslands in Brazil: mowing produces fast effects, but hay transfer does not
ABSTRACT Subtropical Campos Sulinos grasslands, in South Brazil, are among the most biodiverse grasslands of the world. As climatic conditions lead to high productivity, disturbance are critical to maintain their diversity. Long-term exclusion, on the other hand, leads to plant species losses and changes in composition. No studies on the restoration of these

4. Maize Productivity, Mycorrhizal Assessment, Chemical and Microbiological Soil Attributes Influenced by Maize-Forage Grasses Intercropping
Abstract Mycorrhizae are important components of agroecosystems and the diversification of crops stimulates the abundance of arbuscular mycorrhizal fungi and the participation of symbiosis in plant growth. This experiment examined mycorrhizal assessment, chemical and microbiological soil attributes in a maize-forage grasses intercropping compared to a maize-

5. Nitrogen management of forage grasses for nutrition, seed production, and nutrients in residual straw
Resumo: O objetivo deste trabalho foi avaliar a nutrição, a quantidade de nutrientes na palhada residual, a produtividade de sementes puras e a qualidade de sementes das gramíneas forrageiras tropicais 'Mombaça' e 'Xaraés', quando submetidos ao manejo de nitrogênio em cobertura. Foram conduzidos experimentos em campo nos municípios de Rancharia e de P

6. Fungal endophytes of Panicum maximum and Pennisetum purpureum: isolation, identification, and determination of antifungal potential
ABSTRACT This study aimed to isolate and identify endophytic fungi from the forage grass P. maximum and evaluate their ability to inhibit the growth of plant pathogenic fungi. One sample from P. purpureum grass was also included. Surface disinfected stem fragments were used for endophytic fungal isolation. One hundred and twenty-six endophytic fungi were iso

7. Crop Response to Gypsum Application to Subtropical Soils Under No-Till in Brazil: a Systematic Review
ABSTRACT The use of gypsum to improve the root environment in tropical soils in the southeastern and central-western regions of Brazil is a widespread practice with well-established recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient a

8. Fatty acid profile in vertical strata of elephant grass subjected to intermittent stocking
ABSTRACT The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate climate grasses and the literature with tropical grasses

9. Performance and metabolite profile of dairy cows fed tropical grasses and concentrates containing crude protein with low or high degradability
ABSTRACT Ten Holstein-Zebu crossbred cows distributed into two simultaneous Latin squares (5 × 5) as a 2 × 2 factorial arrangement formed by chopped sugarcane or elephant grass silage, both with high or low protein degradability supplements and a corn silage as a control treatment, were compared using orthogonal contrasts. The studied variables were the pe

10. Corn Yield and Foliar Diagnosis Affected by Nitrogen Fertilization and Inoculation with Azospirillum brasilense
ABSTRACT The biological nitrogen fixation (BNF) process in grasses is caused by diazotrophic bacteria, particularly Azospirillum brasilense. However, studies are lacking on BNF efficiency to define how much mineral nitrogen (N) can be applied to achieve more sustainable high yields. Furthermore, there should be an analysis of whether urea with the urease enz

11. The chemical composition, fermentation profile, and microbial populations in tropical grass silages
The objective of this study was to evaluate the fermentation profile, chemical composition and microbial population and losses in the silages of signalgrass and Mombasa grass fertilized with the following levels of nitrogen (N): 0, 30, 60 and 90 kg/ha. The grasses were harvested at 70 days of regrowth, chopped and then ensiled in laboratory silos that had 20

12. Influência de um fragmento florestal sobre as comunidades de macroinvertebrados de um córrego tropical degradado
Land use changes have resulted in large environmental impacts, and in agricultural landscapes sometimes only forest fragments remain. However, riparian forest remnants can influence positively stream water quality, and serve as refuge to aquatic species sensible to deforestation. We evaluated if the presence of a riparian forest remnant influences the struct
