Mombaça grass yield as a function of nitrogen fertilization based on the use of the chlorophyll meter

open access: yesSemina: Ciências Agrárias, 2021
The objective of this study was to evaluate the yield and agronomic efficiency of mombaça grass achieved with the management of nitrogen fertilization, based on the nitrogen sufficiency index (NSI) calculated using measurements obtained with a ...

Interspecific and intraspecific foraging differentiation of neighbouring tropical seabirds [PDF]

open access: yesMovement Ecology, 2021
AbstractBackgroundSocial interactions, reproductive demands and intrinsic constraints all influence foraging decisions in animals. Understanding the relative importance of these factors in shaping the way that coexisting species within communities use and partition resources is central to knowledge of ecological and evolutionary processes.

Forage production and quality of tropical forage legumes submitted to shading [PDF]

open access: yesCiência Rural, 2019
ABSTRACT: Find shade-tolerant species is essential to the success of silvopastoral systems, increasingly frequent in recent years. In legumes, which have potential of biological nitrogen fixation, there is a great lack of knowledge when in shaded environments.The cultivation of four tropical forage (Neonotonia wightii, Pueraria phaseoloides ...

Predation Pressure and Gastropod Foraging: A Tropical-Temperate Comparison [PDF]

open access: yesEvolution, 1981
Over the last two decades, theories of species diversity (Huston, 1979), antipredation phenomena (Vermeij, 1978) and reproductive effort (Cody, 1966) have involved a temperate-tropical gradient in predation. Comparative tropical-temperate observations in a number of systems support the case for an increase in predation intensity with a decrease in ...

A Transcriptomic Analysis of Stylo [Stylosanthes guianensis (Aubl.) Sw.] Provides Novel Insights Into the Basis of Salinity Tolerance

open access: yesFrontiers in Sustainable Food Systems, 2022
Tropical areas have a large distribution of saline soils and tidal flats with a high salinity level. Salinity stress is a key factor limiting the widespread use of tropical forage such as Stylosanthes guianensis (Aubl.) Sw.

Measuring smallholder dairy farmers’ social valuation of climate mitigation: a case study from Kenya

open access: yesPastoralism
Livestock systems in Sub-Saharan Africa contribute substantially to greenhouse gas emissions and are highly vulnerable to climate change. In Kenya, smallholder dairy farmers need to balance productivity with environmental sustainability while facing ...

Mulato II (Brachiaria sp.)

open access: yesEDIS, 2011
Mulato II is a semi-erect perennial apomictic grass that can grow up to 9 ft tall. Brachiariagrasses, including Mulato II, are tropical warm season forages native to Africa and are the most widely grown forages in tropical South America.

Root exudate fingerprint of Brachiaria humidicola reveals vanillin as a novel and effective nitrification inhibitor

open access: yesFrontiers in Molecular Biosciences, 2023
Introduction: Biological Nitrification Inhibition (BNI) is defined as the plant-mediated control of soil nitrification via the release of nitrification inhibitors. BNI of Brachiaria humidicola (syn. Urochloa humidicola) has been mainly attributed to root-

Perspectives on Reducing the National Milk Deficit and Accelerating the Transition to a Sustainable Dairy Value Chain in Zimbabwe

open access: yesFrontiers in Sustainable Food Systems, 2021
The Zimbabwean dairy industry is massively underperforming, as evidenced by a reduction in milk yield from 262 million liters in 1990 to <37 million liters in 2009 and a steady but slow increase to 82 million liters in 2021.

Evaluating early selection in perennial tropical forages [PDF]

open access: yesCrop Breeding and Applied Biotechnology, 2019
Abstract Perennial grass hybrids of Urochloa are evaluated for at least two years during the screening stage trials (SS) and advanced trials (AD) in breeding programs, an expensive and time-consuming process. In this study, we aimed to evaluate the potential for early selection of cultivars in this breeding scheme.
