Differential productivity response of rain fed sorghum (Sorghum bicolor L.) genotypes in relation to graded levels of nitrogen in Kellem Wollega zone of Ethiopia, East Africa
(International Journal of Life Sciences, 2015)
Field experiment was conducted at Haro Sabu Agricultural Research Center using three sorghum genotypes (Lalo, Chemada and Local) during the rainy cropping season of 2014 with an objective to determine the effect of nitrogen ...
Factors associated with small-scale agricultural machinery adoption in Bangladesh : census findings
There is strong advocacy for agricultural machinery appropriate for smallholder farmers in South Asia. Such ‘scale-appropriate’ machinery can increase returns to land and labour, although the still substantial capital ...
Effect of climate change on spring wheat yields in North America and Eurasia in 1981-2015 and implications for breeding
(Public Library of Science, 2018)
Wheat yield dynamic in Canada, USA, Russia and Kazakhstan from 1981 till 2015 was related to air temperature and precipitation during wheat season to evaluate the effects of climate change. The study used yield data from ...
Index insurance and climate risk management : addressing social equity
(John Wiley & Sons, 2018)
Motivation Fair distribution of benefits from index insurance matters. Lack of attention to social equity can reinforce inequalities and undermine the potential index insurance holds as a tool for climate risk management ...
Adoption of drought tolerant maize varieties under rainfall stress in Malawi
(John Wiley and Sons, 2018)
We examine adoption of drought tolerant (DT) maize varieties using a four‐round panel dataset from six districts in Malawi. There is an increase in adoption of DT maize from 3% in 2006 to 43% in 2015 in our data. We focus ...
Conservation agriculture in maize- and wheat-based systems in the (Sub)tropics: Lessons from adaptation initiatives in South Asia, Mexico, and Southern Africa
Conservation agriculture's underlying principles—minimal soil disturbance, soil cover and crop rotation—are increasingly recognized as essential for sustainable agriculture. This article summarizes three contrasting cases ...
Modeling the response of tropical highland herbaceous grassland species to climate change: The case of the Arsi Mountains of Ethiopia
Global warming is forcing plant and animal species to respond either through pole-ward or upslope migration to adjust to temperature increases, and grassland communities are not an exception to this phenomenon. In this ...
Weather index insurance for managing drought risk in smallholder agriculture : lessons and policy implications for sub-Saharan Africa
This paper reviews recent advances in, and challenges for, weather index insurance for managing drought risk in smallholder agriculture, with a focus on sub-Saharan Africa. Despite its promise to integrate local agricultural ...
Farmers' prioritization of climate-smart agriculture (CSA) technologies
Addressing climate change impacts on agriculture is special challenge. There are number of factors that influence the extent to which farmers in a particular location adopt CSA technologies. This study applied a participatory ...
Spatial analysis to support geographic targeting of genotypes to environments
Crop improvement efforts have benefited greatly from advances in available data, computing technology, and methods for targeting genotypes to environments. These advances support the analysis of genotype by environment ...
