Tomato is an annual flowering fruit fruiting crop, hi high temperature, hi water, hi light, hi phosphorus potassium. Nutrient management of tomato is made up of several stages as base fertilization, flower preparation, flowering, fruiting, color transforming maturing, flower with fruit.

Base fertilization: Generally organic fertilizer or farm fat fermentation finished with the main high-phosphorus fertilizer 8-10KG such as monoammonium or diammonium potassium dihydrogen phosphate can also be used.

Flower preparation: treat with high nitrogen fertilizer, be assisted with 25-10-10 or 30-10-10. Proper temperature of 25-28 centigrade in daytime or 10-15 in the night.

Flowering: Foliar spray boron fertilizer, the ground can be appropriate impulse monopotassium phosphate 2-3KG per acre. This period of daytime temperature to 25-28 degrees, 10-15 degrees at night is appropriate

Fruiting: prefer to high potassium-based, especially like potassium nitrate 13.5-0-46, the ground water flushing can be appropriate to add calcium fertilizer foliage, this stage of the daytime temperature to 25-28 degrees, 10-15 degrees at night is appropriate

Color transforming maturing: This stage mainly in the high potassium category, especially like potassium nitrate 13.5-0-46, the ground water flushing can be applied, the foliage spray monopotassium phosphate to promote the conversion of mature (to Anda phosphate potassium 1:500 ratio spray) This stage during the day temperature to 28-35 degrees, 10-15 degrees at night is appropriate.

Flower with fruit: A crop of fruit after the basic flower in the same time with the ground water flushing fertilization to balance fertilizer and then use high potash fertilizer to follow then repeat again, the foliage in the flower for a long time to add boron, fruit for a long time to add calcium fertilizer. This stage temperature requires 30 degrees to 35 degrees.
