Fertilizer

Apply 2/3 before planting and 1/3 as top dressing.First top dressing of nitrogen directly after tuberinitiation.Requires high nitrogen rates during earlydevelopment.Nitrogen (N): 120% in comparison to other mediumearly varieties.High level of phosphorus is recommended toencourage root system development.Pay attention to the amount of organic fertilizer toavoid later mineralisation.Manganese and magnesium will encourage a strongfoliage and prevent premature senescence.

IVORY RUSSET has a long dormancy.Allow the seed to acclimatize to the local conditions before planting.Do not store the seed potatoes lower than 5°C. Warm them up sufficiently before planting.IVORY RUSSET reacts well to the cutting of big sized seed. Optimum result from 3-4 weeks prior toplanting.Always treat IVORY RUSSET seeds and soil against Rhizoctonia.The best quality will be reached on fertile and light soil types.

Irrigation is advised under dry circumstances.IVORY RUSSET is susceptible to Alternaria. Start treatments at flowering time.IVORY RUSSET is fairly resistant to spraing.

IVORY RUSSET is quite early maturing, haulm killing shouldn't give any problems.Tubers have a quick skin set, but have thin skins. Pay extra attention at harvest.
