Abstract:
A field experiment were sown on the 3th of April 2016 at the
Demonstration Farm of College of Agricultural Studies, Sudan
University of Sciences And Technology, Shambat, to study the effect of
some Fertilizers and their time of application on growth and forage
productivity of mung bean. The treatments were arranged factorially in
split - plot design with four replications. Application Time as the main plot
involved three times of application: before sowing, with sowing and after
sowing. Types of fertilizers as the sub plot involved four types of
fertilizers: without Fertilizer (control), 50 kg /ha (organic manure), 100
kg/ha (diammonium phosphate), and 10 L/ha (humic acid). Different
characters were measured include plant height (cm), stem thickness (cm),
number of branches/plant, number of leaves/plant, fresh weight /plant (g)
as well as dry weight /plant (g). The results revealed that there is a highly
significant difference of different application time and types of fertilizers
and their interaction on plant height, number of leaves, and fresh forage
and dry forage. Highly significant differences (p ≤ 0.01) were recorded in
types of fertilizers and interaction between different application time and
types of fertilizers for number of branch and significant difference (p ≤
0.05) of application time for number of branch and stem diameter. There
was no significant Difference in types of fertilizers for stem diameter. The
highest height of the plant (28.78 cm), a maximum stem diameter (6.43
cm), the highest number of branches/plant (9.37), the largest number of
leaves/plant (31.69), the best Stover of fresh (815 kg /ha) and dry weight
(161 kg / ha) were recorded form 50 kg/ha organic manure applied after
sowing.
