  • Looking beyond grain for overall benefit from wheat in mixed crop livestock systems Michael Blϋmmel1, Arun K Joshi2, Nils Teufel1 and Iain A. Wright1 1 International Livestock Research Institute (ILRI), India and Ethiopia 2 Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT), Nepal Wheat for Food Security in Africa Conference Addis Ababa, 8-12 October 2012 1
  • Topics Wheat straw as commodity, contribution to overall income from wheat production Wheat straw trading as feed back mechanism and entry point for wheat straw value chain improvement Opportunities and limitations of improving wheat straw through multidimensional wheat improvement 2
  • Peri-urban wheat straw trader, New Delhi 3
  • Wheat straw-grain price ratios in South AsiaStraw price/grain price in %, as collected during village survey 2009/10 % (n) Normal Peak Punjab 35 (18) 48 (18) Haryana 19 (18) 30 (18) N Teufel et al. (2011) In Ethiopia in 2006/2007 Gebremedhin estimated reported wheat straw - grain price ratios of 10 to 27% 4
  • Wheat straw collected from fodder traders and farmersCategory Variety Price [Rs/kg straw] n New Delhi wheat straw markets best Not known 4.25 2 best WH-283 4.00 1 medium Not known 3.85 2 medium 1553 4.00 1 Village Kapriwas, dist. Rewari, Haryana best C-306 3.50 1 best WH-283 3.40 1 good DBW-17 3.00 1 good PBW-502 3.00 1 good PBW-550 3.25 1 medium PBW-343 3.00 1All samples collected for feeding trials 04/2009 5
  • Price: quality relations in wheat straw traded monthly in New Delhi from 2008 to 2009 6
  • Wheat straw collected fromfodder traders in Delhi and PatnaCategory ADF [%dm (SE)] Price [Rs/kg straw (SE)] n New Delhi wheat straw markets best 48.8 (0.21) 4.43 (0.11) 36 good 49.3 (0.21) 4.21 (0.07) 72 medium 49.1 (0.24) 4.00 (0.09) 42 Patna straw markets best 50.7 (0.16) 3.26 (0.08) 48 good 50.9 (0.14) 3.07 (0.06) 72 medium 51.6 (0.21) 2.85 (0.08) 35Samples collected monthly for NIRS analysis 07/2008 – 06/2009 7
  • Price-quality relations in wheat straw traded monthly in New Delhi and Patna from 2008 to 2009 8
  • Wheat straw trials investigated for straw traitsHTM = Heat Trial Early maturity: India (Indore, Ugar, Ludhiana, Karnal and Varansi) Bangladesh and PakistanHTNM = Heat Trial Normal Maturity: India (Ugar, Ludhiana, Karnal) Bangladesh and Pakistan (Islamabad, Bahawalpur and Faisalabad)SAWYT = Semi Arid Wheat Trial: India (Indore, Ugar, Dharward and Varanasi) Bangladesh, Nepal and PakistanESWYT = Elite Spring Wheat Trial: Bangladesh and Pakistan1st DRYT = 1st Drought Yield Trial: India (Indore, Ugar and Dharward) and Pakistan2nd DRYT =2st Drought Yield Trial: India (Ludhiana, Karnal and Varanasi), Nepal and Pakistan 9

  • ConclusionsIn times of peak demand in wheat straw prices can approach half that of the grainPrice premiums for higher quality wheat straws on average about 11 from intuitively small differencesIncluding straw traits in cultivar choice increases probability of having premium straw qualityVary strong clustering of cultivar types for grain and straw yield and for straw quality 15
