Effect of Glomusintraradices and Organic Fertilizer on the Yield and Quality of Maize Grown in Calcareous Soil
Two field experiments were carried out at the Agricultural Research Station of Nubariaduring two summer
seasons of. This work was to study the effect of arbuscularmycorrhizal fungus (AMF) under four rates of compost and two
rates of nitrogen fertilizer as percent of the recommended dose onthe yield and quality of maize grown in calcareous soil.
These field experiments were arranged statistically in a split- split plot design in randomized complete blocks with three
replicates. The development of root length colonization % was significantly increased in the inoculated plants more than the
un-inoculated plants. The highest significant increases in shoot dry weight was (120g/ plant) and their NPK uptake were
117.7, 51.6 and 530.9 kg/ha, respectively as an average of the two seasons in the inoculated plants with Glomusintraradices
at C75% and N100%. Grain yield was significantly increased in the inoculated plants with G.intraradices in the presence of
C75% and N100%(9.7 t/ha) compared to the non-inoculated plants ( 9.0 t/ha).Inoculated Zeamays with G. intraradices gave
the highest significant increases of corn oil (5.0%) and protein (6.0%) as compared to the non-inoculated plants ( 4.5 % and
5.3 % , respectively ) in the presence of C 75 % and N 100% .The results showed that inoculation with AM fungus in the
presence of C75% and N100% of the recommended doses enhanced the soil fertility including the increase in the availability
of N, P and organic matter content in soil.
