Investigations were conduced with greenhouse tomato cultivar Megana cultivated in a plastic tunnel without heating. Plants were grown in containers filled with medium peat. The fertilization g/cubic dm substrate was applid as follows: N-1.5, P-0.6, 0.8, 1.0, K-2.5, Mg-0.6. In addition, the foliage feeding with Busz 1 (0.5 percent) was applied in weekly intervals, starting in the third week after planting. Plants were headed above 6th cluster. The highest yield was obtained from the plants fertilized with 1 g P/cubic dm substrate fed with Busz 1 (5.96 kg/plant.) Phosphorus doses had no effect on the yield in the combinations without Busz 1. In the combinations with Busz 1, the decrease of N content in leaves and substrate was noticed, however, vitamin C content in fruit and P content in substrate was higher in these combinations. The doses of phosphorus had no effect on vitamin C and content in fruit
