Juwel is suitable for all kind of soils, seed tubers should be pre-sprouted. As a precaution seed treatment against Rhizoctonia solani is recommended. Juwel should be planted in rows allowing 28 – 30 cm between tubers and 75 cm between rows in a well-prepared seedbed.
Nitrogen: 140 – 150 kg / ha Phosphorus: 100 kg / ha Potassium: 200 – 250 kg (preferably sulphate) Magnesium: 70 – 80 kg
Juwel is not sensitive to Metribuzin. Use a very strong Phytophthora program: especially first application in time by a strong systemic fungicide is very important; afterwards routine chemical control depending on weather conditions.
Crop should show senescing before killing the haulm. Dry matter content should be more than 18 %. Skin set should be finished before harvest. Avoid mechanical damage during harvesting.
Avoid fluctuation of temperature during storage otherwise sprouting is possible.
