چکیده مقاله:

During the two last decades, the managerial techniques of irrigation such as partial root zone drying (PRD) have been improved on some plants. In this research, the effect of partial root zone drying on water use efficiency in rapeseed was studied in a field study. This research was conducted as factorial experiment in complete randomized blocks design with four replications. The experiment consisted of two factors including irrigation in three levels (that were full irrigation, alternative furrow irrigation and fixed furrow irrigation) and three mulch levels that were without mulch, using mulch in row and between rows and using mulch only between rows. The results showed that water use efficiency had significant differences in irrigation treatments. Water use efficiency in alternative furrow irrigation increased by ۱.۷۰ and ۹.۶۱% compared to control irrigation treatment and fix furrow irrigation, respectively. Also, the effect of different levels of mulch application on water use efficiency had significant effects and the highest water use efficiency and grain yiled in rapeseed were obtained alternative furrow irrigation treatment with mulch application between and in rows and  is recommended in similar climatic conditions.
