Abstract
Field experiment was carried out during winter seasons 2013-2014 at two locations Grdarash Research Station – Collage of Agriculture – University of Salahaddin / Erbil and Einkawa research station belongs to ministry of Agriculture / Erbil. The experiment consists of 15 treatments.Seed soaking for 3 and 6 hr. and seed treated with KNO3 and ZnSO4 at three concentrations 0.2. 0.5. 0.7٪ for 3 and 6 hr. as well as tap water and control (without soaking). The experiment conducted using RCBD with three replication. The results showed: the significant differences found among the control and priming with KNO3 0.5 ٪ for 6 hr. with other treatment in the field emergency at both locations Grdarash and Einkawa 77.66 and 91.66٪ respectively. The priming with KNO3 0.5٪ for 3 hr. was superior in total chlorophyll contain 63.54 at Grdarash as well as the priming with KNO3 0.5٪ for 3 hr. and 6 hr. was dominance for the number of days to flowering. maturity. number of seed/pod. KNO3 0.2٪ priming for 3 and 6 hr. had higher value for branch number/plant.Biological yield 423.5 and was dominance in Einkawa location in the numbers of days to 50٪ flowering. while ZnSO4 at 0.2 . 0.5. 0.7٪ was superior in total chlorophyll content. No of pods/plant. pods weight and No of seed/pod (64.19. 34.16. 11.57. 1.22) respectively at Grdarash.
