تأثير الموليبدنيوم و البورون لبعض صفات النمو في الباقلاء (Vicia faba L.)‎

Abstract EN

Field experiment was conducted during the winter season 2014-2015 in Abu gosrah in the district of Abu-Alkhaseeb which is located 14.5 km south of center of Basra province, in order to study the effect of adding molybdenum (Mo) and boron (B) on growth recipes of broad bean (Vicia faba L.) var.

A factorial experiment was carried out with the design of randomized complete block design (RCBD) with four replicates, and included two factors; the first includes macerating seeds with three concentrations of molybdenum ( 0, 5 and 10 mg l-1 ), and the second factor was spraying with boron solution which included three concentrations ( 0, 25 and 50 mg l-1 ), which were added to the plant in the form of boric acid (17.4 % B).

The results showed that macerating the seeds of broad bean with 10 mg l-1 molybdenum has led to a significant increase in the number of days from planting until 50% flowering , Plant height , Number of branches ,leaf area , Pod length and dry weight of shoots by (16.26, 8.5 ,28.2 , 91.

14, 35.56 and 61.94)% respectively compared with control.

Spraying plants with 50 mg B .L-1 gave the highst gave the highest average number of days from planting until 50% flowering , plant height , Number of branches per plant, leaf area , Pod length , dry weight of shoots by (7.26, 8.00, 27.19, 31.55, 18.3 and 40.44)% respectively, compared to the control.

Interaction between the two treatments showed a significant positive effect in plant height , number of branchs and dry weight of shoot by using 10 mg Mo L -1 + B 50 mg L–1.
