  • Development of low-N tolerant maizevarieties International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Savannas ofWCA • Savannah is the most productive environment for maize production • Soils in the savannas are generally low in organic matter and available nitrogen • Availability and use of fertilizer also limit maize productivity International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • ConcernAlthough,Combined use of organic manure and nitrogenfixing cover crop can make a difference tomaize productionHowever, there is the concern on - declining levels of soil fertility - high proportion of crop residue being fed to livestock, burned or consumed by termites International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Therefore,Maize genotypes with improved N-useefficiency (greater grain yield per unitavailable soil N) can increase productivity ofmaize based systemEspecially,In combination with technologies that improvesoil fertility - crop rotation - organic manure - judicious use of inorganic fertilizers. International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Breeding methodology• Screening of germplasm from diverse sources• Generation of low-N tolerant populations• Recurrent selection to improve on levels of N-tolerance in desirable populations• Line development to generate inbreds tolerant to low soil-N International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org

  • Low-N - Summary• Levels of tolerance to Low-N enhanced in three populations• Conversion of three adapted populations for tolerance to low soil nitrogen, initiated• Funds provided for on-farm trials of varieties• Plans underway to release two Low-N varieties in Nigeria and Ghana International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Technology dissemination• Technological innovations in resource-limited agricultural systems will continue to play an important role in solving food insufficiency in developing countries.• Development of technologies alone will not translate to increased food production unless – such technologies are appropriately deployed and – farmers are empowered to sustain them. International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Approaches totechnology • Extension system of the 1960sdissemination – Wasteful – Prescriptive – No back-up inputs – No training International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Approaches (2) • Training and Visit (T and V) Merits – Well-trained agents – Suitable messages – Improved management and technology testing – Active participation of farmers Criticism – Poorly managed – Irrelevant technologies often promoted Suggestions for improvement – Full farmer participation – Meeting needs of women – Private sector involvement – Improvement in quality of agricultural education International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Limitation • Farmer empowerment – Farmers should be empowered to test and promote technologies Technology dissemination efforts should concentrate on developing innovative mechanisms that empower farmers to help themselves International Institute of Tropical Agriculture – Institut international d’agriculture tropicale – www.iita.org
  • Low-N and DT maizein Bauchi State, • 100 kg of LNTP-Y C5 maize varietyNigeria • 100 kg of Drought Tolerant Maize variety (TZE Comp 3 DT) • Each farmer was provided with 1 kg of the new seed to plant as island within the farmer’s main field. • Simultaneously with the evaluations, 2 farmers were identified to produce seeds in isolation.
