  23. 23. CHALLENGES  Critical shortage of vehicle  Shortage of training (long and short)  Problem of soybean value chain  Extreme variability in soil fertility ( 80% farm field is < 5 pH of soil)  Mono cropping practices  Serious disease problem ( Chocolate spot of FB)  Inefficient inoculants on FB  Un adequate and untimely budget release  Untimely start of the project ( late planting)
  24. 24. LESSON LERNT  inoculants are promising in enhancing bean yield  Yield variability across the farmers’ field is high  Both P and inoculants are important for common bean, but P rate is low  Different CB,FB and SB varieties respond differently, best varieties were identified  OC and available P are +vely correlated with bean yield ( improvement is important)  Soil acidity management is critical issue  Farmers were aware to use inoculants
  25. 25. Way forward for 2014  Early start and procurement of the input materials as much as possible  Further scaling up  Issue of soil acidity management  Revision of P application rates  Strengthen approaches of scaling up( e.g innovation plot form)  Focus on value chains for soybean  Improving soil OC  Focus for FB disease and compatible inoculants
