2001
Thafer, M.
This study is aimed at determining the impact of treated wastewater irrigation on plant growth, dry matter, grain yeld of bread wheat and on the soil characteristics. The field experiment was carried out on a sandy soil in Agadir region. Two types of water were used: the rainfall supplemented with treated wastewater irrigation of which five treatments were tested. Leaf, root content of nitrogen, phosphorus, potassium, calcium and magnesium was increased proportionally to the irrigation doses. The electrical conductivity of the soil increased from the start to the end of the experiment. The evaluation of soil nutrients for the three soil layers, indicated their accumulation with increasingt irrigation dose. As a result, we found that the wheat crop could complete its growing cycle using supplementary irrigation to bread wheat gave us the highest grain yeld in comparison to the other doses.
