Abstract

A pot assessment was conducted to verify the impact of bio-fertilizer EM and dried powder of water hyacinth plant (Eichhornia Crassipes) or turmeric plant (Curcuma longa) either or integrated applications on plant reaction of tomato seedlings cv. 888 F1 infected by M. incognita at greenhouse conditions. It is remarkable to detect that the experienced binary applications accomplished better results than single ones did. Evidently, data showed that all tested components enhanced tested plant criteria and also diminished nematode parameters. The bio-fertilizer EM application plus dry-leaf powder of water hyacinth plant mixed with oxamyl at triple doses each showed the maximum value of whole plant length (73.0%), whole plant fresh weights (231.8%), shoot dried weight (246.8%), leaves number (126.52%) and branches number (41.51%), respectively. In the meantime, the tetra application of (bio-fertilizer EM + turmeric + water hyacinth +oxamyl) accomplished the maximum decrease percentage in total nematode final density, galls and egg-masses number with values of 97.4, 86.5 and 91.5%, correspondingly. It was obvious that nitrogen, phosphorus, potassium concentration, chlorophyll and phenol contents were apparently reduced by nematode infectivity by deferent degrees. All tested applications showed significant increase percentages of in nitrogen, phosphorus, potassium concentration, chlorophyll and phenol contents greater than those of nematode alone.
