Getting the focus right: production constraints for six major food crops in Asian and African farming systems
To determine the most important production constraints and associated yield losses for six major food crops in 13 farming systems with high poverty in Sub-Saharan Africa, South Asia and East Asia, surveys were conducted ...
Nitrogen and phosphorus capture and recovery efficiencies, and crop responses to a range of soil fertility management strategies in sub-Saharan Africa
This paper examines a number of agronomic field experiments in different regions of sub-Saharan Africa to assess the associated variability in the efficiencies with which applied and available nutrients are taken up by ...
Compendium of deliverables of the conservation agriculture course 2014
This book is the result of the hard work of 5 CIMMYT trainees who work on sustainable practices in India, Ethiopia and Zimbabwe, and participated in the 2014 visiting scientist program ?Conservation agriculture: Laying the ...
Up-scaling and out-scaling conservation agriculture technologies: The case of a local innovation platform in eastern Kenya
An innovation platform (IP) is a forum for diagnosing problems of common interest, exploring opportunities and solutions. Such a platform comprises a multi-sectoral and/or a multi-institutional partners. The initiative ...
Short-term effects of conservation agriculture on Vertisols under tef (Eragrostis tef (Zucc.) Trotter) in the northern Ethiopian highlands
Soil erosion and declining soil quality are the major constraints for crop production and sustainable land management in Ethiopia. A conservation agriculture (CA) experiment was conducted in 2006 at Gumselasa, Northern ...
Medium-term effects of conservation agriculture based cropping systems for sustainable soil and water management and crop productivity in the Ethiopian highlands
In the northern Ethiopian highlands, croplands yield extremely high volumes of storm runoff and are the major contributor to sediment load in the rivers. A medium-term tillage experiment was carried out (2005?2010) on a ...
