The influence of Brassica germinated grinded seeds cabbage, cauliflower, broccoli and radish seeds singly or integrated with oxamyl against M. incognita infecting soybean cv. Giza 22 were studied under glasshouse conditions (25 ± 5°C) of the Unit of Nematology Research, Faculty of Agriculture, Mansoura university. Cabbage germinated grinded seeds (GGS) singly or integrated with oxamyl at half dose showed the maximum values in improving total plant fresh weight (113and 67.0%), plant length (49.5 and 42.9%), shoot dry weight (105.4 and 42.3%) and number of leaves per plant (166.7and 100.0%), as well as accomplished the best results in reducing number of galls, eggmasses and females on root system of soybean plants since their values were amounted to 80, 83.8 and 80.9% respectively. Likewise, similar trend was achieved as cabbage integrated with oxamyl at half dose with values of 68.9, 82.2 and 77.4% for number of galls, eggmasses and females comparing to nematode, respectively. The concentrations of nitrogen, phosphorus, potassium and the content of total phenol were gradually decreased, while the content of total chlorophyll clearly increased with the infection of nematode alone. Otherwise, all studied treatments solely recorded significant increase in the content of nitrogen, phosphorus, potassium and total contents of phenol and reduced the content of total chlorophyll with a negative value.
