In order to determine the best time use and adequate dose of four herbicides control weeds in dryland chickpea (Cicer arietinum L.) fields, we performed present experiment 4 x 5 m plots. Fourteen treatments were carried out that from 1 9 included trifluralin. Treatments 1, 2, 3 with increasing doses trifluralin (480, 720, 960 g ai ha-1) applied 30 days before planting. 4, 5, 6 15 7, 8 consisted...
