“…Différents matériels de paillage sont alors utilisés: les pailles, les résidus de récolte, les bois-raméaux fragmentés (BRF), les sachets plastic, etc. L'utilisation de la bouse de vache et d'autres produits organiques incorporés contribue aussi à l'amélioration de l'humidité du sol (Kpadonou et al, 2019. D'une manière générale, ces pratiques contribueraient efficacement à l'amélioration de la productivité et à l'adaptation contre les poches de sécheresse avec des émissions de GES relativement faible (Tableau 1).…”

The requirements for a quality and sufficient market gardening production are far from being achieved. This problem has been exacerbated by climate change, while the demand for vegetables increases in proportion to the population growth and to the high rate of urbanization. Alternative practices are proposed by Climate Smart Agriculture (CSA) that basically promotes a trade-off between improvement of crop productivity, climate change adaptation and mitigation. How could this approach contribute to positively impact the market gardening sub sector and vegetable production in particular? Therefore, this paper in a first phase identified and described potential practices from literature and in a second one analysed their performances. The first phase had three steps: (1) the review of the fundamentals of the CSA concept in regard to market gardening production, (2) identification and description of potential practices and technologies based on literature and (3) a qualitative comparative analysis of their potentialities vis-a-vis CSA criteria to identify recommendable practices. The second phase analysed quantitatively the performances of the recommendable practices using the Evidence of Resilient Agriculture (ERA), a meta-dataset online platform with Amaranthus, Lettuce/Cabbage and Tomato as test crops. This provides a comprehensive overview of the adequacy of these practices with CSA requirements. Thus, laying the foundation for scaling up the CSA concept in vegetable crops production with the reorientation and improvement of good practices against climate change. Practices and technologies recommended for a CSA, are those related to the use of improved crops varieties, ground-water mobilisation through on-farm water pits creation where water table is shallow and surface water unavailable, drip irrigation and use of mulching, optimal organic fertilizers application and rationale chemical application (like microdosing), and finally the use of processing and conservation techniques that demand less energy and promote renewable energy like solar driers. The results from the ERA analysis revealed an average change of 69.5% for Amaranthus, 53.3% for Lettuce/Cabbage and 36.4% for Tomato by applying those practices together. Thus, the combination of these practices and technologies in one package as CSA technologies could be favourable for CSA scaling up in vegetable crops production system in West-Africa.

“…Les rendements en légumes frais ont été évalués après trois récoltes échelonnées pour chacune des espèces végétales à 4, 6 et 8 semaines après le repiquage pour A. cruentus puis 6, 10 et 14 semaines après le repiquage pour S. macrocarpon et O. gratissimum. Des échantillons de légume frais (tige plus feuilles) ont été collectés à chaque récolte, pesés à l'aide d'une balance (de précision 0,01 g), séchés à l'étuve à 60°C pendant 72 heures afin de déterminer la teneur en matière sèche des légumes récoltés (Adjogboto et al, 2019;Kpadonou et al, 2019;Likpètè et al, 2019).…”

The development of microdose fertilization in West Africa on indigenous leafy vegetables (ILVs) is an alternative to nutrient management constraints. To overcome nutrient inefficiency, various application methods of urea (per hill, band/strip or uniform spreading of fertilizer dissolved in water) were tested on-station from 2015 to 2017 to identify the easiest and least time-consuming method of application. Several mineral fertilizers doses: 0, 10, 20, 30, 40, 60 with an incorporation of 5 t/ha manure (dry basis), and 40, 80 kg urea-N/ha without manure (half and full recommended rates, respectively) and farmers’ practice (FP, 100 to 120 kg/ha of NPK fertilizer and urea) were tested to determine the optimal microdose to be applied for sustainable production of ILVs. Two timings of application for the mineral fertilizer (at transplantation and 14 days after transplanting) were tested to identify the best timing. The methods of mineral fertilizer application by micro-dosing under Amaranthus cruentus L. showed similar performance in terms of fresh yield (FY), water productivity (WP) and economic gain. The early application of urea recorded a performance equivalent to the late one, giving market gardeners a sufficient time for effective application. Fertilizer micro-dosing application at 40 urea N/ha with manure improved significantly FY and WP compared to the control without mineral fertilizer and the recommended rate in contrast to Occimum gratissimum L. In farmer fields, the microdose at 60 kg/ha of urea gave similar performance in terms of FY yield compared to farmers’ practice for S. macrocarpon and O. gratissimum. Fertilization micro-dosing resulted twice in reduction of fertilizer application by producers in ILVs production. It is therefore necessary to widely disseminate this technique for the production of ILVs in Africa.
