الملخص EN

A two year field trail was carried out at the Demonstration Farm of the Faculty of Agriculture -Omdurman Islamic University to test the effect of organic nitrogenous sources ( Chicken and Cattle manure ) single or integrated with mineral nitrogen on the vegetative growth and yield of wheat (plant cv.

Condor ).

The treatments were arranged in a randomized complete block design with four replications.

Results of growth parameters (plant height, number of leaves, number of tillers and plant dry weight) showed that organic and mineral fertilization and their integration significantly increased growth parameters compared to the control in the two seasons.

On the other hand, there are non-significant differences between single addition of chicken and cattle manure and the recommended dose by Sudanese Agricultural Research Corporation of the mineral fertilizer on growth parameters except for plant height which was affected by single addition of chicken manure, while the integration between organic and mineral fertilizer showed significant differences.

Also the result revealed that application of organic manure alone had non-significant effect on the yield of grain and straw in comparison with recommended mineral fertilizer dose while its integration with mineral fertilizer had significant effects in both seasons.

The optimum dose in this study was 4.18t/ha of chicken manure mixed with 43kg/N of urea.

All results of the study indicated that chicken manure showed better performance than cattle manure
