Water use efficiency of wheat under simultaneous water and salinity stress conditions by using date palm leaves biochar

A pot experiment carried out to study the effects of date palm leaves biochar on WUE and some other performance components of wheat (Triticum aestivum L.) under conjunctive water and salinity stress conditions. The experiment was factorial based on a randomized complete design (RCD) with three replications during one growing season (2015-16). The treatments included biochar application rates (0 and 3% w/w), irrigation interval levels (3, 7 and 12 days) and water salinity levels (1.1, 3.8, 8 and 12 dS/m). The results showed significant (P
