    • Introduction
      • Napier grass fodder is recommended as a basal forage in smallholder dairy systems (SHD) systems in Uganda.
      • Napier stunt disease (NSD) reported in >60% of the districts in Uganda (Fig.1), is a threat to the SHD industry.
    • Figure 1: Spread and level of infection of NSD in Uganda (Kabirizi and Alicai, 2010) Low High Medium Water bodies Infection levels No disease G U L U K O T I D O L I R A M U K O N O K I T G U M A P A C M A S I N D I P A D E R A R U A M O R O T O H O I M A B U G I R I R A K A I K A L A N G A L A M P I G I M U B E N D E K A M U L I K U M I M A S A K A K A T A K W I M A Y U G E K I B O G A K I B A A L E N E B B I S O R O T I K A S E S E B U S H E N Y I N A K A P I R I P I R I T K Y E N J O J O W A K I S O Y U M B E I B A N D A N A K A S E K E I G A N G A M O Y O A D J U M A N I I S I N G I R O K I R U H U R A L U W E R O P A L L I S A N A K A S O N G O L A K A B A L E T O R O R O M B A L E K A M W E N G E S E M B A B U L E M B A R A R A N T U N G A M O K A Y U N G A K A B A R O L E B U N D I B U G Y O R U K U N G I R I J I N J A K A P C H O R W A K A N U N G U B U S I A S I R O N K O K A B E R A M A I D O K I S O R O K A M P A L A N 9 0 0 9 0 1 8 0 K i l o m e t e r s o w i u v e e r b Unsurveyed districts u r v e
      • Highlights of surveys results
      • Study districts: Kabalore (highlands), Masaka (districts around Lake Victoria Crescent zone); Soroti (lowlands) & Busia (near Kenya boarder)
      • Constraints to Napier grass production were: land shortage, low yielding varieties & NSD.
      • Over 80% (n=120) of sampled Napier grass fields in Masaka district were affected by NSD .
      • Farmers had a mixture of improved and local varieties in the same field—all varieties affected.
      • Most widely grown cultivar was Pennisetum 99) ( Kawanda 4 x P. Typhoides hybrid).
      Key Achievements and Outputs
    • Highlights of results of survey results (cont)
      • Over 80% (n=171) of respondents in Kabalore & Soroti were not aware of NSD.
      • NSD incidence & severity were highest in Masaka & lowest in Busia (Fig. 2).
      • Farmers in Busia had acquired a new variety from Kenyan farmers.
      • NSD reduced fodder yield by >60% (Fig. 3).
      • Rouging was major method of disease control.
      • No reports of smut in study areas
      • Studies on biomass yield & nutritive quality conducted (to be presented by Erasmus & Clementine, respectively)
    • Fig. 2: NSD incidence (%) and severity (1-3) in study areas 1= no stunting, 2 = moderate stunting and 3 = severe stunting
    • Mean herbage DM yield (t/ha/yr) Fig. 3: Effect of NSD on herbage yield Districts
    • 2. Current situation: Case of Masaka district
        • Field visits & reports from farmers show a decline (20-40%) in NSD incidence due to:
        • Increasing importance of SHD as a source of income
        • Awareness creation by NaLIRRI through:
          • Media, local newspapers & farmer-talk-shows
          • Farmers participate in NARO/NaLIRRI scientific meetings, field days/workshops
          • Publications (leaflets, posters etc---)
          • On-station trials----demonstrations on NSD symptoms & control measures
          • Farmers use recommended agronomic practices
            • Rouging and manure application
            • Recommended harvesting techniques, weeding---
    • Effect of manure application on fodder yield & NSD incidence
      • Farmer reports & on-station trials have shown manure application most effective control measure----reduces (> 30%) NSD incidence & improves (>40%) fodder yield (Fig. 4).
        • Manure improves soil fertility----enhances plant growth-----plants become less susceptible to disease stress.
        • Manure interferes with multiplication & survival of disease organisms (Mugerwa, 2010). through:
          • Modification of the micro-environment or
          • Enhancement of natural enemies to disease causing organisms
    • Fig. 4: Effect of manure application on fodder yield and NSD incidence 2008 2009

      • On-farm evaluation of low value crop residues with improved diets – EAAPP/World Bank New (PhD)
    • 6. Lessons learned
      • NSD is still a threat to the dairy sector in Uganda---no tolerant variety—need to continue screening local and introduced varieties & evaluate IPM technologies e.g manure application.
      • Demand for alternative forages/feed resources has increased---need for more research.
      • No Napier head smut reported in Uganda---need for more studies.
    • Lessons learned (cont.)
      • Good collaboration among research team members is a key to successful implementation of project activities
      • Developing and managing effective partnership is difficult BUT very important in technology development & dissemination.
      • Policy makers & local leaders play a key role in the control of NSD--- & in sourcing for research funds.
    • Lessons learned (3)
      • Media is a key stakeholder in technology development & dissemination
      • Regular monitoring and feedback is important in
      • improving stakeholders’ skills & knowledge.
      • Farmer workshops, leaflets, newspaper articles, radio programmes are the most effective tools in disseminating technologies.
      • Empowering farmer leaders with monitoring skills reduces research costs and increases research outputs
      • The Research Perspective
      7. Proposed policy briefs “ Quarantines and movement restrictions of diseased materials would be a good policy tool to supplement recommended control measures BUT lack of enforcement renders it impracticable. This leaves the options: propagation and distribution of clean planting materials”.---- Dr. W. N. Nannyenya (Socio-economist, NaLIRRI)
    • 2. The Perspective of the Ministry of Agriculture, Animal Industry and Fisheries- --Directorate of Animal Resource, Uganda “ Pasture and animal feed resources shall be improved through proper management and utilization of existing natural pastures and by introducing pasture and/or animal feeding interventions in existing natural pastures or crop-livestock farming systems while ensuring sustainable use of the feed resources”---- Mrs. (Rev.) S. Mwebaze, Assistant Commissioner, MAAIF)
