Impact de l'irrigation par les eaux usées épurées sur la productivité d'une culture de tomate de plein champ, le bilan d'azote et la salinité du sol
Abstract
This work is aimed at assessing the impact of irrigation with treated wastewaters on growth, production and nitrogen balance of a tomato crop in the field, as well as the chemical characteristics of the soil. The trial was carried out at the treatment station of Drarga. Two water regimes were used. The results obtained show that water use of tomato was equal to 1937.7 m3/ha.The agronomic parameters were similar for the two treatments but the yield components were better for the 120% ETM treatment. Electrical conductivity of the soil increased from 2.32 dS/m to 5.24 dS/m and 4.30 dS/m respectively, for the 100% ETM and 120% ETM treatments; this difference between the two treatments is the result of the 20% leaching fraction applied on the second treatment that ensures leaching of salts in depth. The soil was depleted in nitrogen, phosphorus and potassium.
