This research carried out in Al- Bassa village at Lattakia province during 2013-2014, to determine the effects of increasing rates of boron and zinc fertilization by foliar spraying, on root nodulation and seed yield of broad beans (Viciafaba L.). Se
eds were planted in plastic pots (15 kg capacity), filled with sandy-silty soil, characterized by its poor content of boron, and represents most of lands in the region. Boron and zinc were sprayed by five increasing concentrations (Bo, B25, B50, B75 and B100) and (Zno, Zn25, Zn50, Zn75, Zn10)on broad bean plants at 33 and 65 days post-emergent. Results showed that treatments high significance than control, in termsof root length witch the best treatment was B100Zn100with 31c.m, and 2.85 g for B75Zn75 as a wight of length, on the other hand the best treatment for number of nodules was B75Zn75, 179.03 c.m, B100Zn100 was the best for height of the plant with 100.20, for protein B100Zn100 the best with 37.4%, However, boron and zinc fertilization treatment B75Zn75 is the best, economically.
تأثير التسميد الورقي بعنصري البورون والزنك في تكوين العقد الآزوتية ومكونات غلة الفول العادي Vicia faba L تحت ظروف الساحل السوري
This study was conducted at AL-buyarat AL-garbya, west Palmyra during
2010/ 2011 and 2011/2012 growing seasons to determine the optimum date and
plant density for sowing two faba bean varieties. The studied factors were two
sowing dates (15/10 and
5/11), plant densities (16.7 and 11.1 plants/m2) and two
varieties of faba bean (kobrusi and Hama1). Results showed that sowing on
early date 15/10 resulted in increasing plant height, number of branches/plant
and pod length as compared with 5/11 sowing date.
