| Abstract | ||
| Iraqi wonder and Barcelona eggplant hybrid cultivars were sown on different planting dates (1/9/2002 to 7/3/2003) to evaluate their reaction to the disease complex Fusarium solani and Meloidogyne javanica, under field conditions in jabela/Babylon, Iraq. The plants were inoculated with M.javanica 5000 J2/plant and 19 g/plant F. solani grown on wheat bran medium. The date 15/12 showed the greatest difference in disease complex severity between the two hybrid cultivars which were 42.6% and 10.8% for Barcelona and Iraqi wonder hybrids respectively. The percentage of crop loss was very large between the pathogens inoculated and non-inoculated plants. Crop weigh were the highest in January,15 planting dates for pathogens inoculated Barcelona cultivar plants (42.2 ton/h) where as production was reduced to 4.2 ton/h for the October, 1. The results were similar for Iraqi wonder plants which reached 75.88 ton/h for December, 15 planting date compared with 55.56 ton/h for Barcelona at the same planting date, for pathogens non-inoculated plants. Production was reduced to 69.2 and 45.2 ton/h respectively, for cv. Iraqi wonder and Barcelona inoculated with the disease complex pathogens in December 15 planting date. | ||
