Response of old and new cowpea varieties to insecticide spray regimes in the Sudan Savanna of Nigeria
This paper determines the response to insecticide spraying of old cowpea varieties developed in the late 1970s and new varieties developed in the 2000s – in order to determine whether the new varieties have less requirement for spraying.
Four Seasons of Learning and Engaging Smallholder Farmers: Progress of Phase 1
Book-length report published at the end of the TLII project’s first phase (2007–2011) to document the lessons learned across the 10 target countries. Chapters report on experiences with specific grain legumes in specific regions.
Tropical Grain Legumes in Africa and South Asia: Knowledge and Opportunities
A report that brings together the information required to develop an effective research and development strategy for tropical legumes, reviewing trends, research impacts, and constraints in sub-Saharan Africa and South Asia.
Potential of cowpea (Vigna unguiculata L.) for dry season seed and fodder production in Sahelian sandy soil of Niger
Recent surge in dry cowpea seed price, grain and fodder demand in Niger Republic has resulted in the search for appropriate cultivars for dry season production for seed, grain, and fodder. Studies have found that dry season cowpea production stands first as an alternative for farmers to increased income, grain, seeds, and fodder and enrich the soil for the next rainy season.
Genetic gain in yield and agronomic characteristics of cowpea cultivars developed in the Sudan Savannas of Nigeria over the past three decades
This paper evaluates a field study conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semi-determinate cowpea genotypes developed in the Nigerian Sudan savannas from 1974 to 2004.
A systems and partnership approach to agricultural research for development – Lessons from Ethiopia
A paper presenting a methodology based on the innovation systems approach that has been used in Ethiopia to facilitate agricultural innovations and the diffusion of new technologies, illustrated with experiences in scaling up three grain legumes.
Improvement in grain and fodder yields of cowpea genotypes representing four decades of breeding in the Nigerian Sudan savannas
This paper presents the findings of a field study conducted to determine the rate of genetic improvement in the grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004.
Potential of triple and double cropping with and without irrigation in the Sudan and Northern Guinea Savanna Zones of West Africa
The rapid increase in population and consequent pressure for food is driving agriculture towards greater intensification in West Africa. Various options including double and triple cropping, with and without irrigation, have to be employed for intensification to succeed. Double and triple cropping options with irrigation in Sudan and Sahel savannas and without irrigation in the northern Guinea savanna zones of West Africa were explored as possible options for intensification in these areas.
Lessons from Two Years of Tropical Legumes II: Second Annual Review and Planning Meeting 16–20 November 2009, Bamako, Mali
Lessons from two years of the Tropical Legumes II Project, funded by the Bill & Melinda Gates Foundation (BMGF), which aims to bring about significant increases in the productivity and production of tropical legumes to improve farmers’ income, nutrition quality, and livelihoods in the drought-prone areas of SSA and South SA.
