Temperature-dependent phenology of Plutella xylostella (Lepidoptera: Plutellidae) : simulation and visualization of current and future distributions along the Eastern Afromontane
There is a scarcity of laboratory and field-based results showing the movement of the diamondback moth (DBM) Plutella xylostella (L.) across a spatial scale. We studied the population growth of the diamondback moth (DBM) ...
Climate change and agriculture : adaptation strategies and mitigation opportunities for food security in South Asia and Latin America
During the past two centuries, the world has witnessed a remarkable increase in the atmospheric concentrations of the greenhouse gases (GHGs), namely carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as a result ...
Development of cost effective small No-till seeder for two wheel tractor in Bangladesh
(Bangladesh Agricultural Research Institute, 2017)
Two wheel tractor (Power tiller) is the common means of soil tillage and other farm operations in Bangladesh due to easy access in fragmented land size with affordable price. A low cost and small robust 2WT driven (12 hp) ...
Different ways to cut a cake : comparing expert-based and statistical typologies to target sustainable intensification technologies, a case-study in Southern Ethiopia
(Cambridge University Press, 2016)
Understanding farm diversity is essential to delineate recommendation domains for new technologies, but diversity is a subjective concept, and can be described differently depending on the way it is perceived. Historically, ...
A comparative analysis of conservation agriculture systems: Benefits and challenges of rotations and intercropping in Zimbabwe
Increasing soil degradation in southern Africa and the potentially negative effects of climate change demand ?greener? solutions to reverse this trend. Conservation agriculture (CA) has been proposed as one of those solutions ...
Genotypic trade-offs between water productivity and weed competition under the System of Rice Intensification in the Sahel
Yield, water productivity and weed-inflicted Relative Yield Losses (RYL) under Recommended Management Practices (RMP) were compared with the System of Rice Intensification (SRI) under double-cropping for two seasons and ...
Conservation agriculture, increased organic carbon in the top-soil macro-aggregates and reduced soil CO2 emissions
Background and aims: Conservation agriculture, the combination of minimal soil movement (zero or reduced tillage), crop residue retention and crop rotation, might have the potential to increase soil organic C content and ...
Cumulative effects of reduced tillage and mulching on soil properties under semi-arid conditions
Declining soil productivity is one of the greatest challenges facing smallholder agriculture. This study assessed effects of reduced tillage and mulching on soil organic carbon, bulk density, infiltration and maize yield. ...
