Potato seed tuber "Elfe" 50 pcs
Elfe combines high yield with excellent appearance and quality. It extends the range of packable varieties, has very low tuber rot and provides excellent eating quality.
Elfe is an early maturing, quality table potato with a very high marketable yield. The tubers have a smooth skin, a very nice shape and are excellent for washing and packaging.
Elfe is highly adaptable and grows beautiful tubers under very different environmental or climatic conditions, but Elfe should preferably be grown in soils with good agricultural conditions and good and consistent water and nutrient supply. A uniform water supply is preferable and best utilized to ensure full yields and crop quality. Very light and/or sandy soils should be avoided without the possibility of irrigation.
The initial development of Elfe is usually rapid if the seed tuber and soil are in good condition. Well prepared seed tubers stimulated by germination can usually be planted early. Non-germination stimulated seed tubers should be planted above a soil temperature of 8 oC. Elfe has a medium to high tuber setting rate. Suitable for packing (40-60mm), the recommended number of tubers per hectare is 43000 tubers per hectare for food quality production.
Elfe responds well to a balanced nutrient supply and nutrient replenishment. Due to its earliness and high yields, N fertilisation should not be exceeded. Approximately 140kg/ha (including soil Nmin and N from organic fertilisation) will suit the needs of Elfe. This amount can be adjusted accordingly by site specific adjustments. A site-specific application of foliar N fertiliser with a focus on N before the start of tuber development will accelerate foliage development, and additional N supplementation may be useful to stimulate foliage development before tuber setting or when very high yields (more than 45t/ha) are expected. In these cases, an additional 20kg N/ha should be applied and usually the application should be stopped at the latest at tuber set. A balanced potassium supply will ensure tuber quality. In soils with medium K supply, 200-250kg K2O/ha is the requirement for Elfe. To ensure good dry matter content, K fertilisation should preferably be carried out with K sulphate and K chloride should be avoided. Potassium should be applied before planting or at the latest shortly after planting.
It is recommended to apply appropriate fungicides (active substances such as Pencycuron, Tolclofos-methyl, Fluotolanil, Fludioxonil) to seed tubers to ensure high yields and high quality of the crop due to Rhizoctonia solani.Elfe has some resistance to potato late blight (Phytophtora infestans),the routine spray programme should focus on prevention,if necessary chemical control of potato late blight should be started on the warning of the local forecasting system, if such a forecasting system is not available, it should be started shortly before the closure of the bakhaks (rows) (full canopy) with appropriate fungicides. In the case of high humidity in the plantation, especially on clay and loamy soils, chemical control should be started earlier in order to prevent primary stem infestation, in which case the preferred systemic (absorbable) active substances (Metalaxyl-M, Mefenoxam, Propamocarb) should be used. The further spray programme (active ingredient, mode of action, spray timing) should be adapted to the weather conditions and the infestation pressure. No specific sensitivities to herbicides containing the active substance metribuzin have been observed.
Defoliation (defoliation) is recommended in order to reduce the harvesting load and to ensure the quality of the crop. However, defoliation of plants should be avoided as long as the foliage is vigorous and green. Harvesting should be done carefully, with soil temperatures not below 12 oC when using a combine harvester. Careful handling and well-applied aeration and drying are beneficial to ensure good tuber quality.
