Effects Of Water Quality On Wheat (triticum Durum L. Var Boussalem) Irrigated With Drainage Water In A Saline Environment Under Palm Grove Conditions, Southern Algeria

Résumé: The main objective of this study was to find the performance of durum wheat (Triticum durum L. var Boussalem) irrigated with drainage water in a saline environment under palm grove conditions. A field trail on a saline sandy soil was carried out at agricultural farm of Technical Institute of Saharan Agriculture Development (ITDAS) in El-Arfiane during winter 2012. Throughout the cycle of wheat fourteen irrigations was applied. The drainage water was imposed with two irrigation frequencies (1 and 2 week intervals). In addition, nitrogen and phosphorus fertilizers were applied in 240 and 180 kg ha-1 respectively. The results showed that the wheat responded positively in this saline condition, the drainage water (EC 14.8 dS m-1) produced high seedling emergence and good vegetative growth, which was followed by an acceptable grain yield (5.56 t ha-1).These yields were not significantly different from those obtained with fresh irrigation water, thus water could be another alternative for irrigation under similar experimental conditions, especially with appropriate nitrogen and phosphorus fertilization at weekly irrigations intervals.
