“…However, intercropping showed contrasting effects depending on species, genotypes, density, season and environmental conditions. The main disadvantage in some intercropping systems is the competition for nutrient, radiation and water use efficiency (Black and Ong, 2000;Sillon et al, 2000).…”

Our research aimed to reveal the capacity of intercropping with Medicago sativa-rhizobia in the amelioration of grapevine growth in agricultural and a Cd/Pb contaminated soils. A local variety of grapevine was cultivated in monocropping and in intercropping with Medicago sativa inoculated or not with its associated rhizobia. Intercropping with alfalfa induced a significant increase in shoot and root biomass of grapevine in the agricultural soil. However, in the contaminated soil, a slight increase in root biomass was observed. Concerning photosynthesis apparatus, we showed that the presence of Cd and Pb in the soil induced a significant decrease in both CO2 assimilation rate and stomatal conductance. Interestingly, intercropping with alfalfa only and with rhizobia alleviate this effect. Similar results are obtained for chlorophyll and carotenoid content. This was associated with a significant decrease in the malondialdehyde level in leaves and roots of grapevine cultivated in intercropping with alfalfa with and without inoculation in the two soils as compared the monoculture treatment. Comparison between treatments revealed also that intercropping with alfalfa induced a decrease in the activities of some enzymes implicated in the defence to the oxidative stress such as catalase and superoxide dismutase. Regarding soluble protein content, it is needed to signal the improvement of this parameter with the intercropping system in the contaminated soil when compared to the monocropping treatment. This work highlights the importance of the use of legumes in intercropping with grapevine as intercrop plant non-competitive for soil nutrient and proving N supply for associated plants.

Les territoires du bassin de la Caraïbe sont très exposés aux effets du changement climatique, avec des probabilités de renforcement des périodes de sécheresse pouvant impacter lourdement la production agricole. La question de l'économie de l'eau s'y pose avec acuité, et des alternatives sont recherchées à différents niveaux d'échelles, allant du territoire aux systèmes de culture. Cet article porte un éclairage sur les bénéfices attendus des systèmes multiespèces (SME) pour l'économie de l'eau en zones tropicales. Il s'attache dans un premier temps à rappeler les bases biophysiques des transferts d'eau entrants et sortants au sein du continuum sol-plantesatmosphère, tout en pointant les modifications du cycle de l'eau imposées par l'implantation de SME. Dans un second temps, il exprime les possibilités offertes par le design spatio-temporel des SME pour la recherche de meilleures efficiences de l'eau, tout en mettant en avant le rôle de la modélisation pour la recherche des scénarios les plus viables au regard de la complexité du fonctionnement de ces systèmes. Ces approches devront nécessairement i) composer avec les pratiques culturales visant à l'économie de l'eau à la parcelle (travail du sol, mulching, choix spécifiques et variétaux, etc.), et ii) s'inscrire dans une chaîne logistique allant de la parcelle au territoire pour accroître la robustesse des services climatiques.

In the Mediterranean area, the introduction of cover crops in vineyards is hampered by the risk of severe competition for water. Belowground interactions are still not very clear in this perennial-herbaceous association. This work was aimed at characterizing the development of the root systems of associated crops and the soil water dynamics. It also investigated whether water competition could be the cause of vine vigour and yield reductions. Experiments were conducted in a 4-year-old association (vine -tall fescue) and in a weed controlled vineyard. Water transfers in the soil were estimated on the basis of the soil water potential and soil hydrodynamic properties. The vine root system was concentrated in the soil under the row, whereas the intercrop highly colonized a soil compartment under the inter-row to a depth of approximately 1 m. Despite this spatial complementarity in root distribution, intercropping reduced the amount of soil water available for the vine crop. The low soil water content reduced soil water conductivity thereby limiting water transfers, despite a significant gradient in the soil water potential. This conductivity did not differ significantly between treatments but the intercrop enhanced the infiltration of winter rainwater, probably by limiting surface runoff. There was temporal complementarity in this association since the period of intense water uptake by the intercrop occurred earlier than noted for the vine under bare soil conditions. Nevertheless, the competition for water was limited by better refilling of the soil water profile during winter in the intercropped treatment. The intercrop clearly interacted with the vine and decreased its vegetative vigor. Since predawn leaf water potential and stomatal conductance did not differ among treatments, mechanism(s) other than competition for water (e.g. nutrient competition, allelopathy) may be responsible.
