Research and technology options for increasing crop yields and enhancing soil fertility

  1. 1. Research and technology options for increasing crop yields and enhancing soil fertility By A.L. Abate University of Juba
  2. 2. South Sudan Eco-Zones  Potentially arable land 195,000 km2 (30%)  Grazing land 260,000 km2 (40%)  Heavily forested 146,000 km2 (23%)  Swamps & water 45,000 km2 (7%) surfaces
  3. 3. South Sudan Eco-zones & Human Activities  Arid Belt Gum collection and marketing  Green Belt Agriculture e.g. tea, palm oil, food crops  Flood plains Mainly cattle keeping; some agriculture  Hills & Mountains Mixed agriculture  Ironstone Plateau Predominantly agriculture with livestock  Nile/Sobat corridor Cattle and fish
  4. 4. Consequences of two Wars on South Sudan Agriculture • Loss of germ plasm • Loss of farming skills • Loss of interest in farming • Development of alternative sources of livelihood
  5. 5. Recent statistics  More than 80% of cereal production grown by traditional methods  90% of agricultural production is rain fed  Crop failures are common  Overall, very low crop yields  between 10 to 30 % in Eastern Equatoria  between 1 to 10 bags of 50 kg maize per acre in parts of Western Equatoria  Total lack of quality seeds  Flooding prevents planting in Northern Bahr el Ghazal
  6. 6. Performance indicators of South Sudan agriculture Parameter South Sudan Kenya Uganda Rural share of population, % 99.9? 67 86 Arable land of land area, % 30.0 7.0 25.7 Arable land per capita, ha 6.4 0.14 0.24 Irrigated land of cropland, % ? 1.5 0.1 Fertilizer use, 100g ha-1 of arable 0 346 6.0 land
  7. 7. RESEARCH OPTIONS FOR SOUTH SUDAN  Action Research On-farm trials Demand-driven Research Applied Research Adaptive Research
  8. 8. INTERVENTIONS FOR INCREASING YEILDS - a  Intercropping  Crop rotation – seasonal or annual  Use of cover crops Reduced tillage – minimum tillage Composting Organic matter additions
  9. 9. INTERVENTIONS FOR INCREASING YEILDS - b  Provide agricultural inputs  Provide better agricultural practices  Form farmer cooperatives  Initiate farmer cooperatives
  10. 10. INTERVENTIONS FOR INCREASING YEILDS - c  Improve road infrastructure  Emphasize applied agricultural research  Develop a suitable extension service  Encourage FDI
