Two field experiments were carried out during the seasons of 2001 and 2002
to study the effect of using organic manure ( Recycling the agricultural resides) as
individually and/or as mixed with chemical fertilizer (NPK); The important results are
as following: Using organic manure as Nile compost ( Recycling the agricultural resides)
at rates between 2-3 tons/fed. which equal 40-60 nitrogen units caused an
enhancment in Vicia faba growth. Also the obtained data reveals that. organiC fertilizer
as alone or mixed with the chemical fertilizer gave a superiority in total pods yietd and
its components if compared with using chemical nitrogen fertilizer alone. The nutrional values expressed as the contant of protein.N,P ,K, Fe,Mn,Zn
and Cu, the statistical analysis of the obtained data indicated no great effect of using
nitrogen fertilizer as individually and/or as mixed with chemical fertilizer.
