an application of new irrigation methods to increase water use efficiency is essential, due to global water shortages, and as well a consumption of more than 70% of fresh water in the agricultural sector. in this study, the effect of full irrigation (fi), partial root-zone drying (prd) treatments at two levels (provision of 75% of et (prd75) and 55% of et (prd55)) vs. deficit irrigation treatme...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
