Design, assessment and improvement of crop management systems in sunflower

Résumé

This paper reviews different methods used to design, assess and improve crop management systems (CMS) in sunflower. The strengths and weaknesses of each method are shortly described and a general framework is suggested to combine them in a logical framework. · Methods for designing and evaluating CMS have been developed for main grain crops combining participatory workshops, field test in experimental stations and pilot farms, evaluation using multi-attribute models and crop simulation. Some of these methods have been applied to sunflower. · Sunflower crop models should integrate more biotic factors to predict actual yield and simulate the interactions between genotype, physical environment, management and the incidence and damage caused by pests, weeds and diseases. Decision-support models based on dynamic crop models should be developed and disseminated to make easier the use of models by extension services. Including virtual experiments in the dialogue between technical institutes, cooperatives, plant breeders and farmers will challenge the existing relations between the actors of innovation.
