Evidence that dicot-infecting mastreviruses arep articularly prone to inter-species recombination and have likely been circulating in Australia for longer than in Africa and the Middle East
Viruses of the genus Mastrevirus (family Geminiviridae) are transmitted by leafhoppers and infect either mono- or dicotyledonous plants. Here we have determined the full length sequences of 49 dicot-infecting mastrevirus ...
Biomass in crop-livestock systems in the context of the livestock revolution
Mixed crop-livestock systems are the dominant source of livelihood supporting more
than 80% of people living in the developing world and producing 50% of world
cereals, around 34% of the global beef production and about ...
Selection of Hyperspectral Narrowbands (HNBs) and Composition of Hyperspectral Twoband Vegetation Indices (HVIs) for Biophysical Characterization and Discrimination of Crop Types Using Field Re ectance and Hyperion/EO-1 Data
The overarching goal of this study was to establish
optimal hyperspectral vegetation indices (HVIs) and hyperspectral
narrowbands (HNBs) that best characterize, classify, model,
and map the world’s main agricultural crops. ...
Length of Growing Period over Africa: Variability and Trends from 30 Years of NDVI Time Series
The spatial distribution of crops and farming systems in Africa is determined by the duration of the period during which crop and livestock water requirements are met. The length of growing period (LGP) is normally assessed ...
Assessing woody biomass in African tropical savannahs by multiscale remote sensing
Woody biomass production is a critical indicator in evaluation of land use management
and the dynamics of the global carbon cycle (sequestration/emission) in
terrestrial ecosystems. The objective of the present study was ...
Annual forage legumes in dryland agricultural systems of the West Asia and North Africa Regions: research achievements and future perspective
Forage legumes are vitally important to animal production
in the dryland farming systems of the Mediterranean
region. Of the diverse forage-legume species
adapted to the Mediterranean climate, vetches, (Vicia
spp.), ...
The Impacts of an Improved Technology Package on Production Efficiency: The Case of Wheat Farms in the Northern State of Sudan
Technical efficiency among wheat farms in the Northern State of Sudan was estimated using a
stochastic frontier production function approach. Empirical findings show that technical inefficiency is
important in explaining ...
