| Abstract | ||
| 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. | ||
