“…The results show that the SALTMED model was able to predict dry matter and grain yield of quinoa under different irrigations conditions very well. The results obtained for total dry matter are in agreement with Hirich et al (2012) and Pulvento et al (2013) who predicted dry matter of quinoa grown in the south of Morocco and south of Italy, respectively, with the SALTMED model obtaining an R 2 of 0.98 and 0.96, respectively. Similarly, Silva et al (2013) reported …”

“…The good results obtained comparing simulated SWC content with observed SWC are in agreement with those reported by Silva et al (2013) and Pulvento et al (2013) who calibrated the SALTMED model using SWC data at certain depths, using a soil moisture probe. In the calibration phase, the simulated yield and total dry matter values were very close to the measured ones (Tables IV and V).…”

Given the current water shortage in North Africa, improving water management to produce more crop per drop is vital. In addition, the introduction of drought-tolerant, less water-consuming crops such as quinoa is of great interest. To understand the response of quinoa to water stress in terms of biomass and grain yield under various irrigation management strategies, the SALTMED model was employed using field measurements during the cropping seasons of 2011 and 2012 at a site in the Marrakech region, south Morocco. Quinoa showed its ability to grow in the south of Morocco and give a good yield under full irrigation. However, the experimental and modelling results showed that under rainfed and deficit irrigation, the grain yield was lower than under the full irrigation treatment and was dependent on water deficit level. The study revealed that a reasonable grain yield of quinoa can only be obtained if it was subjected to moderate water stress conditions. The results indicated that the SALTMED model is able to simulate the quinoa biomass and grain yield under various water deficit levels and that the model can be used in the evaluation of different irrigation strategies.

RÉSUMÉVu le déficit hydrique que connait l'Afrique du Nord, l'amélioration de la gestion de l'eau pour augmenter l'efficience de son utilisation est devenue vitale pour l'agriculture. En plus l'introduction de cultures tolérantes au déficit hydrique et moins consommatrices d'eau est d'un grand intérêt pour la région. Pour comprendre la réponse du quinoa aux différents niveaux de stress hydrique en ce qui concerne le rendement en grains et la biomasse, le logiciel de modélisation SALTMED a été utilisé en y introduisant les valeurs des mesures prises au champ, durant les deux compagnes agricoles 2011 et 2012, dans un site dans la région de Marrakech au sud du Maroc. Le quinoa a montré une grande aptitude à croitre et à donner de bons rendements sous le traitement 100% ETc. Cependant, les résultats expérimentaux et ceux de SALTMED montrent que les rendements en grains sous régime non irrigué et sous déficit hydrique sont inférieurs à celui obtenu sous 100% ETc, et qu'ils sont proportionnels à l'intensité du déficit hydrique. L'étude a révélé que l'on peut obtenir un rendement raisonnable sous déficit hydrique modéré. Les résultats ont montré que le logiciel de modélisation SALTMED est capable de simuler le rendement en grain et biomasse sous différents niveaux de déficit hydrique, et que celui-ci peut être utilisé pour l'évaluation de différentes stratégies d'irrigations.

“…More recently the SALTMED model has been calibrated and validated under dry and wet year conditions using chickpea field data from Southern Portugal by (Silva et al, 2012); using saline irrigation water on quinoa (Chenopodium quinoa Willd) in Denmark (Razzaghi et al, 2011) and in Italy (Pulvento et al, 2013); and in applying deficit irrigation on quinoa, sweet corn and chickpea in Morocco (Hirich et al, 2012(Hirich et al, , 2013.…”

This paper is a follow up from the first paper which described the SALTMED model. In this paper the focus is on the model application using data of tomato and potato from field experiments in Italy, Greece (Crete) and Serbia. Drip full irrigation, drip deficit irrigation, drip as partial root drying (PRD), sprinkler and furrow irrigation were used in three years experiment between 2006 and 2008.In drip irrigated experiments, the drip line was 10 to 12 cm below the surface. Dry matter, final yield, soil moisture and soil nitrogen were successfully simulated. The study showed that there is a great potential for saving water when using subsurface drip, PRD or drip deficit irrigation compared with sprinkler and furrow irrigation. Depending on the crop and irrigation system, the amount of fresh water that can be saved could vary between 14 to 44%. PRD and deficit drip irrigation have proved to be the most efficient water application strategies with the highest water productivity.

“…La quinoa ha mostrado una plasticidad para la tolerancia y/o resistencia al incremento del estrés salino y a la disminución de la disponibilidad del agua mayor que la soja 27 . La quinoa ha permitido mayores niveles de salinidad (solución salina con conductividad eléctrica máximo 52dS/m para quinoa 28 frente a 8,0dS/m para soja 29 ), ocasionando un bajo impacto en los rendimientos del grano 19,[30][31][32] , a diferencia de la significativa reducción que se ha observado en los granos de soja debido a la disminución del contenido de clorofila y de la actividad del fotosistema II 33 . El favorable comportamiento de la quinoa ha sido explicado a través de la respuesta de sus estomas al cierre y del eficiente sistema que posee para realizar ajustes osmóticos importantes para el mantenimiento de la turgencia de la hoja que la muestran insensible a las sequías y a cambios abruptos de salinidad.…”

El diseño de alimentos funcionales a partir de productos vegetales muy estudiados como la soja (Glycine max [L.] Merr.) y la potencialización de productos ancestrales como la quinoa (Chenopodium quinoa Willd.) son estrategias factibles para contrarrestar la desnutrición mundial. El objetivo de la presente revisión es describir las características agroecológicas, de composición, nutricionales y tecnológicas de estas dos especies vegetales diferentes (leguminosa y pseudocereal), basado en las publicaciones previas. Se realizó una revisión en bases de datos (Scopus, Web of Science, Scielo) y se complementó con una búsqueda manual en Google Scholar y páginas web de instituciones acreditadas. Los estudios incluidos (n=117) en esta revisión muestran que la soja se adapta mejor a altitudes bajas (~1.000m s. n. m.), mientras que la quinoa lo hace en un rango de mayores altitudes (500-4.000m s. n. m.) con mayor tolerancia a heladas. Ambas son fuente de una alta calidad proteica por suplir los requerimientos de aminoácidos esenciales sugeridos para niños y adultos sin diferencias significativas (p>0,05), particularmente triptófano y lisina y por los altos porcentajes de digestibilidad (>70%). Sus concentraciones bajas de prolaminas y aceptables de Fe, Zn, Ca, daidzeína y genisteína los convierten en productos de interés para la industria alimentaria. PALABRAS CLAVE
