Improving consistency of yields and quality of large-scale and small-holder bean production in Kenya by precision management of soil, water and pathogens

持续提供高质量的新鲜农产品是肯尼亚新鲜蔬菜面临的一个重大挑战。种植者。豆类产量从5吨/公顷到50吨/公顷不等，由于灌溉无效和土传疾病，高达40%的农产品质量较差。平均产量增加12%，废物减少20%，将使1级产量增加978吨/年;这将产生额外的320万英镑/年，提高粮食安全并改善土壤管理实践。我们将：1）开发灌溉制度工具，以提高作物的一致性; 2）确定生物防治剂对土壤病原体和土壤微生物的影响; 3）确定土壤水分供应对土壤病原体的发病率和严重程度以及生物防治剂的有效性的影响; 4）开发综合防治措施，以提高第一类作物的产量、质量和货架期; 5）在研讨会/农场演示中宣传精确灌溉和生物控制的好处;6）评估产出的社会和经济影响，并实施可持续性改进计划。

Delivering consistent supplies of high quality fresh produce is a significant challenge for Kenya’s freshveg. growers. Yields of beans range from 5 to 50T/ha and up to 40% of produce is of poor quality, due toineffective irrigation and soil-borne diseases. A 12% increase in average yield and a 20% reduction inwaste would raise Class 1 yields by 978T/year; this would generate an extra £3.2M/year, increase foodsecurity and improve soil management practices. We will: 1) Develop irrigation scheduling tools toimprove consistency of cropping; 2) Identify effects of biocontrol agents on soil pathogens and soilmicrobiome 3) Determine effects of soil water availability on incidence and severity soil pathogens andefficacy of biocontrol agents; 4) Develop integrated control measures to improve Class 1 yields, qualityand shelf-life; 5) Promote benefits of precision irrigation and biocontrol at workshops/on-farm demos;6) Assess social and economic impacts of outputs and implement sustainability improvement plans.
