Effect of irrigation with treated waste waters and fertilised well waters on yield of a melon crop grown on three substrates. Mineral balance and uptake kinetics of nutrients | Effet de l'irrigation par les eaux usées épurées et les eaux de puits fertilisées sur la production d'une culture de melon conduite sur trois substrats. Bilan minéral et cinétique d'absorption des éléments nutritifs

This work was carried out in the greenhouse of IAV of Agadir to evaluate mineral nutrition and yield of a melon crop GAL 52 variety grown on three substrates (sand, perlite + coconut fiber and blond peat + perlite) and irrigated with treated waste waters and fertilized well waters. Treated wastewaters allowed getting nitrogen fertilizers, and sand favored good absorption of mineral elements. Sand showed high electrical conductivity and this explains the high sugar content of plants grown on this substrate, equally so, it showed the lowest percentage of drained mineral elements that didn't exceed 19 percent . Melon plants grown on sand gave the highest yield, i.e. 1.8 kg/plant against 1.6 kg/plant on coconut + perlite and 1.5 kg/plant on blond peat + perlite.
