“…The results from the on-farm trials compared the yield and net benefits (profit) between the standard farmer's practice (control) and the integrated management practice (IMP) for the two cultivars. Lukumay et al (2018) showed that the yield advantage and income for the IMP treatments of the two cultivars were more than double compared to the control (Figure 2). The IMPs package emerged as the best-bet for eggplant and tomato.…”

“…The on-farm trials were implemented to validate the suitability of baskets of technologies comprising an elite tomato ("Tengeru 2010") and African eggplant ("Tengeru White") grown under IMP's in the Babati District of Tanzania. The on-farm trials in a randomized complete block experimental design were implemented in four villages (Figure 1) characterized by high (Bermi, Seloto), medium (Gallapo), and low (Matufa) rainfall zones (Lukumay et al, 2018). The trial sites were selected based on agroecological potential (rainfall and altitude), population density, and market access under the Africa RISING program (https:// africa-rising.net/).…”

“…Results from these on-farm trials revealed that growing the two cultivars using IMPs significantly increased yield for Tengeru 2010 tomato from 28 t ha −1 (control) to 64 t ha −1 and from 23.04 t ha −1 to 54 t ha −1 for African eggplant. Lukumay et al (2018) further demonstrated that farmers who applied IMP's attained gross profit margins up to USD 18,300 and 9,600 ha −1 with benefit-cost ratios (BCR) of 8.5 and 4.5 for tomato and African eggplant, respectively. Evidently, the adoption of IMP in vegetable farming at scale could confer a broader societal impact in terms of yield and profits.…”

“…A recent study in Babati district of Tanzania analyzed onfarm trials data to identify promising vegetable cultivars and related management practices (Lukumay et al, 2018). The study compared the yield response and economic benefits of improved tomato (Lycopersicon esculentum; "Tengeru 2010") and African eggplant (Solanum aethiopicum; "Tengeru White:) cultivars grown under improved management practices (IMPs) and standard farmer' practices (SFP's; control) (Lukumay et al, 2018). The IMPs comprised good quality seeds of improved cultivars, healthy seedlings, good agronomic practices (GAP's), and integrated pest management (IPM).…”

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.
