Abstract: Aviation fuel remains the main cost and environmental burden in air transport. This study presents a well-to-wake life cycle assessment (LCA) of canola-based Sustainable Aviation Fuel (SAF) under tropical conditions, based on primary data from Brazilian producers. The analysis encompass...
No-tillage systems are nowadays largely used in Brazilian agriculture, due to its numerous benefits when compared with traditional tillage systems. However, this technique has been little used in livestock systems for pasture renovation. The development of this technique has a great potentia...
The Panicum maximum breeding program of Embrapa released three cultivars (Tanzânia, Mombaça and Massai) from 1990 to 2001. Due to its advantages over the older cultivars (e.g. Colonião and Tobiatã), these are currently the most planted P. maximum cultivars in Brazil. In its second&...
The purpose of this review is to present some of the most recently successful grass+legume mixtures in tropical and sub-tropical regions and to discuss the reasons for low adoption of legumes. A concept in which the main constraints for the advance in using legumes is pre...
ABSTRACT - This systematic review aimed to synthesize evidence on the effects of nitrogen (N) fertilization on forage production, animal performance, and greenhouse gas emissions in tropical pastures. The research question was developed based on the PICOS strategy. A total of 84,629 doc...
Resumo : O objetivo desse estudo foi comparar quatro grupos genéticos de ovinos quanto aos pesos e rendimentos da carcaça. Trinta e três cordeiros, contemporâneos, nascidos de parto simples e sem relação de parentesco foram utilizados no experimento, sendo treze da raça Santa Inês&...
Resumo: Avaliou-se o uso de diferentes fontes lipídicas na dieta sobre as características ruminais como pH, nitrogênio amoniacal em cabras leiteiras e taxa de passagem. Foram utilizadas oito cabras fistuladas no rúmen, não gestantes e não-lactantes, distribuídas em um delineamento em quadrad...
Resumo:. A tecnologia NIR com transmissão por arranjo diodo permite que espectros sejam obtidos em amostras fecais frescas reduzindo do tempo de análise. Entretanto, o alto teor de umidade associado à temperatura no momento da coleta dos espectros, pode afetar a precisão e acurácia...
Abstract: Climate variability poses major challenges to coffee production, particularly due to the increasing frequency and intensity of drought events. Understanding the physiological acclimation capacity of Coffea arabica genotypes to water deficit is critical for developing resilient cultivars. We ...
Abstract: Eleusine indica (L.) Gaertn., commonly known as goosegrass, is one of the most troublesome weed species worldwide. In Brazil, the increasing number of herbicide-resistance cases, particularly to glyphosate, has made goosegrass the most agronomically significant weed species in the count...
