“…These results corroborate the findings of Kanjanja et al, that training provided to farmers in Singida district, Tanzania, had a positively significant effect on the adoption of agroecological practices [33]. Generally, empirical evidence suggests that providing farmers with training through means such as demonstration plots or group membership has a significant impact on the adoption and diffusion of new practices [74][75][76].…”

Crucifers and traditional African vegetables (TAVs) are important to smallholders in Kenya and Tanzania, but yield remains below potential due to pests and diseases. Agroecological production methods present a nature-based solution to pest and disease management in crucifer and TAV production. We explore the status of farmers’ knowledge, attitudes, and practices regarding agroecological-based production pest management practices. Structured and pretested questionnaires were used to collect data from 1071 vegetable farming households in Kenya and Tanzania. Using descriptive statistics, parametric, and non-parametric analysis, our study revealed that less than 20% of farmers had received training on agroecological-based practices and less than 25% were aware of most of these practices. Among those who were aware of the practices and could confirm their effectiveness less than 12% had adopted them, except for crop rotation and handpicking of pests. This study attributes the low adoption to farmers’ negative attitudes towards the practices. Nonetheless, the study further revealed that training significantly and positively influences the adoption of the practices. Therefore, we recommend that governments and other stakeholders promote targeted awareness campaigns and increase access to training on vegetable production using sustainable pest and disease management practices.

“…The ESI and MIC maps can also be utilized to guide the setting up of multi-location trials to investigate the cultivars' local adaptations under different environments and management practices. A recent study in the same district identified the ability to adapt to local conditions as one of the critical drivers of adopting improved vegetables at scale (Gramzow et al, 2018). The maps on the ESI and the most limiting factor provide a factual basis for future surveys to unravel the socio-cultural conditions that limit technology adoption.…”

Land suitability assessment matches crop requirements with available resources to promote sustainable production. Scaling out of sustainable agricultural intensification practices to suitable biophysical and socio-economic conditions reduces the risk of failure and increases their adoption rate. This study applies a geospatial framework to identify potentially suitable sites for extrapolating two improved vegetable cultivars grown under integrated management practices (IMP's) in Babati District of Tanzania. On-farm trial data on the yield and income of two cultivars were used as a reference. Extrapolation was based on the gridded biophysical and socio-economic layers that limit the production of the two improved vegetable cultivars'. The extrapolation suitability index (ESI) showed the areas where cultivation of the two improved vegetable cultivars under IMP's can be scaled-out with a potentially low risk of failure. We generate maps of the most important limiting factor for each cultivar in every pixel to guide the spatial targeting of appropriate remedial measures. Application of these maps will promote evidence-based scaling out of improved vegetable technologies by the extension and development agencies.

“…The multitiller is more versatile as it could be used also in vegetable production and cheaper than the microtiller. The absence of a private sector partner could be explained by the nature of private companies as illustrated by Gramzow et al (2018) on vegetable technology scaling in Tanzania. The study points out that private companies consider the population of potential buyers that could meet optimal profit maximization before recognizing a technology as a profitable investment.…”

This study inquires on the outscaling of the microtiller, a machine developed by the Philippine Rice Research Institute (PhilRice) in the 1990s to address the tedious rice land cultivation in the Cordillera highlands of the Philippines. Stakeholders of the project were interviewed, particularly staff members of PhilRice and the Department of Agriculture; representatives of the Central Cordillera Agricultural Programme, PhilRice’s partner organization in developing and promoting the microtiller; and manufacturers and farmers in the area. It was found that while the machine offered a solution to the highly tedious land preparation issue, four key factors affected its scaling: absence of private sector engagement, lack of a business plan for scaling, lack of extension services, and the presence of a more versatile and cheaper competitor. This study provides empirical evidence of the usability of the set of scaling ingredients developed by PPPLab and the International Maize and Wheat Improvement Center to facilitate analysis of scaling of innovations. The findings may inform scaling opportunities and strategies for farm machines by agricultural research and development institutions across the globe.
