THE ROLE OF TREATING WITH SALICYLIC ACID AND BORON ON GROWTH AND GREEN YIELD FABA BEAN (Vicia faba L.)

Abstract

ABSTRACT The current study was implemented in a private farm at Mosul city in Iraq during the growing season of 2013-2014, to study the effect of treating faba bean plants (Sciabola Verde cv.) with salicylic acid application by soaking the seeds at concentration ( 0 , 350 and 450 ) mg L-1 and spraying plants with the same acid at concentration ( 0 , 10 and 20 ) mg L-1 which applied three times , the 1st one was sprayed at the 2nd . ternode formation , whereas , the others were achieved at monthly intervals. The third factor involved spraing plants with boron at concentrations (0 and 15 ) mg B L-1 which was added as boric acid (17.4 % boron ) in two sprays, the 1st. After one month of germination , while the second spray done during 50% of flowering stage. Superiority of soaking the seeds with 350 mg salicylic L-1 ,Spraying plants with 10 mg salicylic acid L-1 and spraying plants with boron resulted in a significant increase in (plant height, leaf area, dry matter %, number of green pods , and leaves content of boron).
