The Influence of Fertilizer Type and Time of application on Growth and Forage Productivity of Mung bean

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.
