Abstract

A field experiment was conducted at El-Wanysa village, Itsa
district, El-Fayoum Governorate, during the two successive winter
seasons of 2008/2009 and 2009/2010 to investigate the influence of
applied different mineral nitrogen levels and grain bio-inoculation
with, Azotobacter and /or Azospirillum and their interactions on wheat
growth, yield and its attributes as well as N-uptake of either wheat
grain or straw and grain protein content. A split plot design with three
replicates was used. The obtained results could be summarized as
follows:
The results showed significant increases in plant dry weight,
plant height, spike length, 1000-grain weight, grain or straw yield/fed.
N-uptake by straw or grain and of grain protein content either by
increasing the rate of mineral nitrogen or with grain inoculation by the
tested N2-fixers. In addition, the dual grain inoculation with
Azotobacter and Azospirillum performed significantly greater followed
by single inoculation with either Azospirillum or Azotobacter. At any
level of N-fertilizer, the inoculated treatments gave much higher straw
and grain yields than the uninoculated one.
From the economical point of view, it could be concluded that,
the amount of mineral N-fertilizer could be reduced by using grain bioinoculation, which in turn increases soil fertility as well as, minimizes
the production cost and environmental pollution, which can occur by
the excess use of chemical fertilizers.
