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. | ||||
