Abstract
When an insecticide reaches the soil, its fate depends on a 
host of conditions. So, this study aimed to investigate the effect of 
fertilizer types on tomato vegetative growth and fruit yield 
characteristics; the correlation between fertilizer types and tomato 
plants and chlorpyrifos dissipation in soil. Obtained data revealed 
that compost fertilizer gave the best vegetative growth 
characteristics compared with the other fertilizer types (31.6, 50, 
and 70 % above the control level of leaves number, branches 
number/ plant, and plant height, respectively), followed by organic 
and chemical fertilizers. Also, chemical fertilizer gave the highest 
mean yield (0.67 kg pot-1 with 17.9% above the control yield).The 
insecticide dissipated rapidly 1 week after application. Four 
months after application, the amount of residue declined by 99.7 
and 99.85%. Obtained data revealed there is a negligible effect of 
cultivated plants on chlorpyrifos disappearance in soil. The same 
respect, the calculated residue half-life time of chlorpyrifos was 
8.23 and 7.54 days in uncultivated and cultivated soil, respectively. 
Obtained results revealed the critical role of tomato cultivation on 
the dissipation of chlorpyrifos residues in soil compared with 
uncultivated soil. The degradation percent of chlorpyrifos residues 
in treated soil reached more than 99 % of detected amounts in 
unfertilized, biofertilized, and chemically fertilized soil at 4 
months of application, while no detected residues in compost and 
organic manure fertilized soils.
