تأثير التغذية الورقية بالبورون في الحاصل و مكوناته للباقلاء

Abstract EN

A field experiment was conducted at the research farm of dept of Field Crop Sciences-University of Baghdad during two successive winter seasons 2007-2008 and 2008-2009 to study the effect of foliar application with boron on yield and its components of six cultivars of faba bean (vicia faba L.).

The layout of the experiment was asplit- plot design with three replicates .

The six cultivars (S.A, S.B, S.C, ILB1814, ILB1266 and local cultivar) occupied the main plots, while boron concentrations (0, 100, 200, 300) mg.l-1 occupied the sub-plots.

Results showed that the concentration 300 mg.l-1 was superior in percentage of fertility 6.81, 6.38 % in both seasons, respectively, also concentration 200 mg.l-1 was superior in the number of pods per plant 41.01, 41.58 in both seasons, respectively, The concentration 300 mg.l-1 was superior in number of seeds per pod 3.406, 3.583 in both seasons respectively.

While, the concentration 0 mg.l-1 (control) gave the highest seed weight 963, 971 mg in both seasons , respectively, The highest seed yield 3136, 3269 kg.ha-1 obtained from foliar applications by boron concentration 100 mg.l-1 in both seasons , respectively .The results showed that local cultivar was the best in the yield and its components , Therefore, it was recommended to grow the local cultivar with the application of zinc concentration 100 mg.l-1 .
