A field trial was achieved during the two consecutive growing seasons of
200112002 and 200212003 at the Experimental Farm of Faculty of Agriculture, Cairo
University to investigate the associative impact of phosphate solubilizing Bacillus
megatherium, chicken manure, rock phosphate and/or sulfur and its innuence on
growth parameters, fruit yield and oil yield quality of coriander. The results show that
full dose of chicken manure significantly overcame its half dose for all the measured
growth and yield parameters. Application of Bacillus megatherium, as a phosphate
solubilizer, induced matchable results to that obtained due to the use of full dose of
chemical fertilizers, while inclusion of rock phosphate and/or sulfur resulted in further
increases for all tested parameters. An associative effect was found between, chicken
manure, biofertilizer, rock phosphate and/or sulfur. The combined effect of half dose
of chit:'''::.., manure, biofertilizer, rock phosphate and/or sulfur produced reasonable
results while full dose of ch~en manure in presence of the same previous fertilization
sources revealed significant increases, in comparison with the positive control, for all
tested parameters. Biofertilization of coriander combined with full dose of chicken
manure and sulfur augmented limonene oil constituents with 30.69 % over the positive
control. Unalool as the main oil compound of coriander, was increased due to the use
of Bacil/us megatherium combined with full dose of chicken manure that reached 2.5
% over the positive control.
