Farm level best fit rainwater management strategies and soil improvement methods for seed and biomass yield in a maize soy bean intercrop

  1. 1. Andes • Ganges • Limpopo • Mekong • Nile • Volta Farm level best fit rainwater management strategies and soil improvement methods for seed and biomass yield in a maize-soy bean intercrop. 1 Panyan, E.K., 1 Karbo N., 1 Avornyo, F.K., 2 Ayantunde, A.,Kizito3 , F and 1 Tengan, K. 1 Animal Research Institute, P.O.

  3. 3. Andes • Ganges • Limpopo • Mekong • Nile • Volta KEY MESSAGE:  Integrated rainwater management strategies can close yield gabs on smallholder farms  In the event of scaling up, the internal and external inputs become crucial and should be addressed  The PAR as a tool has the potential to build the adaptive capacity of smallholder farmers
  4. 4. Andes • Ganges • Limpopo • Mekong • Nile • Volta OBJECTIVE OF STUDY: The main V2 project objective is to identify, evaluate, adapt and disseminate best-fit integrated rainwater management strategies targeted to different biophysical and socio-economic domains in the Volta basin in northern Ghana.
  5. 5. Andes • Ganges • Limpopo • Mekong • Nile • Volta METHODOLOGY Participatory Action Research:  Innovation Platforms to validate value chain commodities and the problems identified from PRAs  IPs and researchers designed PAR protocol in workshop  Training of farmer experimenters and extension agents on protocol  Farmer field cross visits
  6. 6. Andes • Ganges • Limpopo • Mekong • Nile • Volta METHODOLOGY CONTD. On-farm experimentation: Study location and farmer engagement;  Two districts ( Lawra and Tolon)  Two communities per district (4 communities)  32 Farmer experimenters (16 men 16 women) for all locations  5 Treatments per farmer with 3 replicates on 10m x10m sub-plot On-station experimentation  Experiment repeated with 2 additional treatments (7 treatments).

  8. 8. Andes • Ganges • Limpopo • Mekong • Nile • Volta METHODOLOGY CONTD. Measurements: Dependent variables monitored;  Net grain yield(maize & soybean)  Crop residue yield (bulk dry matter) Cost benefit analysis of interventions Statistical analysis:  SAS was used to analyze the data and Student Newman-Keuls used to separate the means with p<0.05 being significant.

Andes • Ganges • Limpopo • Mekong • Nile • Volta Treatments and average net profits Treatments Average net profit ($) across sites (N=28) Average net profit ($) for Lawra site (N=12) Average net profit ($) for Tolon site (N=16) T1 -8.00 -64.00 32.00 T2 61.00 -19.00 123.00 T3 16.00 -59.00 73.00 T4 56.00 84.00 34.00 T5 116.00 62.00 156.00 N=Number of farmers used in computation
  14. 14. Andes • Ganges • Limpopo • Mekong • Nile • Volta LESSONS LEARNED:  Farmer experimenters appeared more willing to put interventions on poorer lands.  IPs are important in PAR for problem identification and information sharing.  Farmers are motivated by increased yield to have a voice in selection of treatments.  For the resource poor, good agronomic cultural practices could be a means to achieving good yield.
  15. 15. Andes • Ganges • Limpopo • Mekong • Nile • Volta CONCLUSIONS  Integrated rainwater management strategies at farm level have potential to close yield gabs with food security outcomes.  Colossal plant biomass generated has potential to address livestock dry season feed needs and sustain crop-livestock systems.  Where economic decisions are paramount Rainwater management strategies may require site- specific recommendations.
