Putting nitrogen fixation to work for smallholder farmers in Africa Yield and nutritive value of legume residues: Effects of genotypes/harvesting stage Mesfin Dejene ILRI-PhD student, The University of Queensland, Australia. ILRI-N2Africa Annual Planning & Public-Private Partnership (PPP) Validation Workshop 21-23 January 2015 ILRI Campus, Addis Ababa, Ethiopia

2. Putting nitrogen fixation to work for smallholder farmers in Africa Laboratory quality and yield related traits of some grain legume genotypes, Ethiopia  Outline  Grain legumes tested during 2013/14: Quality traits  Common bean: 9 genotypes  Chickpea: 9 genotypes  Faba bean: 9 genotypes &  Soybean: 6 genotypes with three replications  Grain legumes tested during 2014/15: Yield traits  4 Kabuli type chickpea genotypes  4 Dessi type chickpea genotypes &  3 Faba bean genotypes with 4 replications

3. Putting nitrogen fixation to work for smallholder farmers in Africa Range in total nitrogen (N) concentration (%) of CRs of some grain legume genotypes in Ethiopia during 2013/14

4. Putting nitrogen fixation to work for smallholder farmers in Africa Range in Dry matter digestibility (DMD), % of CRs of some grain legume genotypes in Ethiopia during 2013/14

5. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of genotypes on yield related traits of chickpea: Kabuli and Dessi type Dessi type Kabuli type

6. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of genotypes on yield related traits of chickpea: 1. Kabuli type

7. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of genotypes on yield related traits of chickpea: 2. Dessi type Yield related traits

8. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of harvesting stages on yield related traits of chick pea genotypes Harvesting at green stage

9. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of harvesting stages on yield related traits of Kabuli type chick pea genotypes

10. Putting nitrogen fixation to work for smallholder farmers in Africa Effect of harvesting stages on yield related traits of Dessi type chick pea genotypes

11. Putting nitrogen fixation to work for smallholder farmers in Africa Results and implications  There were substantial ranges in laboratory quality and yield related traits between botanical fractions of legume residues and among genotypes.  The preliminary result implies there is considerable potential to increase feed N supply through choice of legume variety and appropriate harvesting stage in crop- livestock systems of Ethiopia.  Optimum utilization of whole plant value needs to be considered
