RESUMEN

Agricultural production in the Rehamna region, Morocco is limited with various challenges including drought and salinity. Introduction of climate resilient and rustic crops such as quinoa was an optimal solution to increase farmer's income and improve food security. This study summarizes results obtained from a research project aiming to develop quinoa value chain in Morocco. The study tackled several aspects including agronomic traits (yield and growth), transformation, quality (nutritional and antinutritional traits) and economic analysis and, finally, a strength-weaknesses-opportunities-threats analysis, lessons learned and development perspectives were presented. From an agronomic point of view, introduced new quinoa cultivars showed higher performance than locally cultivated seeds and, furthermore, the use of irrigation and organic amendment has tremendously improved seed yield by double and three times, respectively, compared to rainfed conditions. Nutritional analysis revealed that protein and phosphorus content remained stable after seed pearling while most of the micronutrients content decreased after seed pearling. However, saponins content was reduced by 68% using mechanical pearling compared to 57% using both traditional abrasion and washing. The economic analysis showed that production cost of quinoa seeds could be further decreased using mechanized intensive tools along with irrigation and organic amendment supply. This study revealed several lessons learned from the field experience and proposed several development actions for each value chain component that can be implemented within a national quinoa program.

RESUMEN

Agriculture is facing many challenges as climate change, drought, and salinity which call for urgent interventions to fast adaptation and diversification such as the introduction of new climate smart and stress tolerant crops such as quinoa. This study aims to introduce new high yielding quinoa cultivars conducted under several agronomic practices (rainfed, irrigation, and organic amendment) and to assess the technical and economic aspects related to quinoa seed production, transformation, and quality. Results obtained from agronomic trials clearly showed that International Center for Biosaline Agriculture cultivars recorded higher yields than locally cultivated seeds. Irrigation and organic amendment had a tremendous effect on quinoa productivity as it increased most of cultivar's yield by more than three times compared with rainfed conditions. Production cost analysis showed that using mechanized production and processing practices combined with irrigation and organic amendment can reduce seed production and processing cost from 2.8 to 1.2 USD kg-1 compared with manual production system under rainfed conditions. The diagnosis of the quinoa transformation pathways revealed different transformation levels, and the production cost increased with the level of transformation due to high cost of labor and raw material. Analysis of quinoa seeds showed that macronutrient content is mostly not affected by pearling process, while micronutrients content was significantly decreased in processed seeds. In addition, total saponin content was reduced to an acceptable level after using mechanical pearling compared with manual abrasion.
