Abstract
Botany and Microbiology Department, Faculty of Science, Sohag University
Different eight microbiological treatments were used for compost
inoculation with the previous microorganisms. .
The study involved three main parts; firstly: microbiological
surveys (fungi and bacteria) of sorghum wastes, farmyard, chicken
manures and composted heaps during composting process, secondly:
study of physical and chemical changes in different composted heaps to
select the best effective composts and thirdly: study the effect of produced
effective composts application on wheat plant (Giza 168) growth as plant
test and soil productivity in addition to soil properties to select the best
effective compost.
According to Microbiological survey and chemical analysis of
nitrogen, phosphorus, potassium, organic carbon, organic matter and
carbon/nitrogen ratio in different composted heaps, the composted heaps
of treatments C, D, E and F were selected to be used in field experiment
and research progress.
Data showed that wheat plant (Giza 168 as plant test) height, spike
length, spike weight, grains number in spike, protein content and yield
significantly increased as a result of the combined application of organic

composts tested with half dose of mineral-N. Also, data showed
significant increases in total nitrogen by using organic compost C
combined with half dose of mineral-N compared to using of full
recommended dose of mineral-N. The highest values of N, P and K were
recorded when mixture of organic compost C combined with half dose of
mineral-N was tested that produced 2.70%, 0.69% & 0.45% in grain and
2.1%, 0.42% & 1.4% in straw, respectively. In general wheat plants
(Giza 168) treated with organic compost C inoculated with mixed
microorganisms (A. niger, Trichoderma hamatum, sterile mycelia, Mucor
racemosus and Bacillus sp.) combined with half dose of mineral-N
showed highly significant increases in plant height, fresh and dry weights,
and NPK uptake compared to those treated with mineral-N only. From
this study and all the previous tests, data revealed clearly that mixture of
compost C + urea 50% were the best effective compost tested and can be
used in cultivation of cultivated soils and reclaimation of newly soils to
increase their fertility and become rich soils.
