1. Evaluation of the effectiveness and economic benefits of Bio-slurry as a fertilizer in Sukuma wiki production

2. General lack of data showing the effects on yields upon bioslurry fertilizer application calls for need for data applicable in a climate, soil, crop, rainfall, and humidity which is relevant to Kenya. A study will be conducted to assess the effectiveness of bio slurry as a fertilizer and whether it can increase crop yields

3. and therefore financial income for smallholders’ farmers and entrepreneurs. The trial will be done in association with the Kenya National Federation of Agricultural Producers (KENFAP). KENFAP have subsidized approximately 8,000 biogas systems at KES 25,000. This subsidy is coming to an end.

4. KENFAP wish to prove the economic benefits of bio slurry fertilizer to enable farmers to purchase biogas units. The weight of Sukuma wiki will be analyzed and compared using experimental parameters including plant height, leaf number and diameter and total harvest weight in a study site in Thika. A total efficacy report will be produced at the end of the trial study.
