Abstract
A field experiment was carried out in the experimental field of the Department of
Field Crops Sciences - College of Agricultural Engineering Sciences - University
of Baghdad during the summer season of 2021 to study the effect of spraying
nano-mineral boron and vitamin B6 on the growth of mung bean crop. The experiment was carried out in the order of the factorial trials according to the RCBD
randomized complete block design and with three replications. The first factor
included spraying nano-boron at two concentrations (100 and 150 mg. l-1
) and
metallic boron at a concentration of 100 mg. l-1
, as well as the comparison treatment (spraying with water only). In comparison, the second factor included
spraying Vitamin B6 in three concentrations (100, 150 and 200 mg. l-1
) and the
comparison treatment (spraying with water only). The results indicated that the
concentration of 100 mg. l-1
boron nanoparticles exceeded by giving it the highest
averages for plant height, number of bacterial nodes, number of branches, number
of leaves, leaf content of chlorophyll, number of flowers, number of pods, the
lowest average for the percentage of precipitation and the highest average for the
fertility rate, compared to the control treatment that gave the lowest averages. The
results also showed that the concentration exceeded 200 mg. l-1
of vitamin B6 by
giving it the highest average for each of the plant height, number of bacterial
nodes, number of branches, number of leaves, leaf content of chlorophyll, number
of flowers, number of pods, the lowest drop percentage and the highest fertility rate
as compared to the comparison treatment that gave the lowest averages. The interaction significantly affected the concentrations of boron and vitamin B6, as the
combination gave 100 mg. l-1
of nano-boron with 200 mg. l-1
of vitamin B6, the
highest average for plant height and number of bacterial nodules reached 151cm
and 12.53 plant node-1
compared to the comparison treatment, which gave the
lowest average. Combining 100 mg. l-1 of nano-boron with 100 mg.
l-1 of vitamin
B6 gave the highest average number of branches and flowers compared to the
comparison treatment, which gave the lowest average.
