Greenhouse experiment on the impact of horse manure or sesame-oil-cake or Bacillus thuringiensis singly and/or integrated with oxamyl on Meloidogyne incognita infecting eggplant cv. Black long at 25±5°C, revealed that all tested treatments obviously improved plant growth response and reduced nematode development. Among the tested components, B. thuringiensis applied alone or mixed with oxamyl gave the highest percentage of increase in plant growth parameters i.e., plant fresh weight and shoot dry weight with values of 105.9 and 85.8% and 127.8 and 107.5%, respectively, as well as the lowest percent reduction of nematode developmental criteria. Moreover, in concomitant application of horse manure plus oxamyl appeared to be the best treatment in suppressing nematode development and improving plant growth parameters, followed by sesame oil-cake plus oxamyl, then sesame oil-cake and horse manure alone. Meanwhile, length of shoot and number of leaves were positively affected by the tested materials either when applied singly or integrated with oxamyl as compared to nematode alone. Regarding N, P and K status in shoots of eggplant, their concentrations were remarkably reduced by nematode infection. Moreover, single application of any organic amendment or bacterium or oxamyl achieved the highest concentration of N, P and K, whereas the concomitant application of horse manure plus oxamyl showed the highest concentration of phosphorus with value of 0.56 ppm. In addition, the previous treatments obviously decreased the total chlorophyll content of eggplant shoot, whereas nematode infection alone recorded the highest increase percentage for this plant parameter with value of 51.3%. |
