Tomato is one of the most widened vegetable crops in the world. Tomato fruits are useful for food. The tomato inflorescence has the form of truss. Tomato belongs to the group of warm season crops. The minimum temperatures for seed germination and plant emergence are between 11 and 13 °C, and the maximum temperatures are around 35 °C. The optimal temperatures of tomato growth are between 20 and 25 °C by day, and between 13 and 17 °C at night. The tomato growth is stopped at temperatures below 10 °C. The tomato plant is damaged by temperature of 0 °C. The tomato growth demands the least 10,000 lx of illuminance. From the ovary fertilization up to the ripe and fully coloured fruit it is necessary 7 till 9 months. That is depended on the variety, the truss position at plant, and the environment conditions. The red colour of fruit does not develop below 16 °C. The tomato growing at the open fields is possible only at frost free period. The period of the tomato growth and development up to the first ripe fruits can be lasted 90 till 110 days.
