2. Introduction and objective
Dry season vegetable production is source of nutrients and income for household farmers in Southern Mali
However, low productivity, insufficient know how, limited access to appropriate varieties, irrigation facilities and good management practices are threats to vegetable production increase in Southh Mali
Hypothesis: optimized & sustainable production is achievable with high performing varieties and good crop management practices
Objective: Identify high performing technologies for intensification of vegetable monocrops in South Mali

3. Methodology
On-farm okra, African eggplant & tomato trials were initiated in & 2015 dry seasons for over 120 farmers in Koutiala and Bougouni districts
Two improved varieties vs 1 local variety and “improved crop management” vs “local management practice” were tested.
Field layout was a factorial “6 treatments of 3 var. x 2 crop manag. practices in RCBD. Each farmer = 1 rep.
Data were collected for veg. fruit weight
Data analysis: separate site ANOVA, combined AMMI of site x year ANOVA, Finley & Wilkinson stability ANOVA in IBP were used

4. Main Results and Discussion

7. Conclusion
(i) Okra: Improved okra variety Batoumabe and the local variety were the most stable varieties (0.7<Sensitivity<1). Okra variety Konni was the most unstable variety but it was highly yielding in favorable environments (Sensitivity>1) and therefore recommended for intensification.
(ii) African eggplant: The local variety under improved and local practices was the most stable genotype ( kg.ha-1). Improved varieties L10 and Keurbine Dao were least unstable but highest performers ( kg.ha-1) in favorable environments (sites & years).
(iii) Tomato: GxExY was not significant. Improved varieties Rio Grande ( kg.ha-1) and Roma ( kg.ha-1) were best than local variety ( kg.ha-1) for all sites and years except Koutiala 2014 (severe water shortages),
(iv) The crop management practices were similar in their effects on the variety performances for all crops.
(v) Yields increased in second year (2015) due to improved capacity of farmers, more and timely availed inputs & equipments.
