A field experiment was carried out in the Research and Production Station, National Research Center, El-Nobaria during the season, 2009 to evaluate the effect of cobalt and different sources of phosphorus fertilizers on the growth, yield quantity and quality of tomato. Treatments can be arranged in descending order as follows: Mono super phosphate (MSP) > Triple super phosphate (TSP) > Rock phosphate (RP). Mono super phosphate (MSP) had superior effect on all growth parameters of tomato shoots and roots yield quantity and quality as well as mineral nutrient constituents of tomato fruits compared with other phosphorus sources. Rock phosphate (RP) treatment gave the lowest values of tomato growth, yield, chemical constituents and mineral composition of tomato fruits. Cobalt addition enhanced all parameters of tomato growth and yield with all sources of phosphorus fertilizers especially with mono super phosphate.
