Medium early, rosy-skinned, quality table potatoes
Laura has low to medium soil and irrigation requirements. Soils with an extremely high risk of tuber spot should be avoided.
Laura produces very attractive, rosy-skinned, medium to large, high quality tubers. The tuber maturation rate is medium, with a recommended planting density of about 46,000 t/ha for table potatoes and about 41,000 t/ha for potatoes for further processing. Tubers intended for seed potatoes are generally recommended to be treated against Rhizoctonia solani.
Laura is sensitive to the herbicide Metribuzine (Sencor, etc.). Higher doses or post-emergence in-stand applications are not recommended. Routine preventive treatment against potato late blight is recommended.
Laura produces very attractive, pink-skinned, medium to large tubers of excellent eating quality suitable for processing into fries.
Laura is a medium-mature, red-skinned, high-quality table potato. The long, oval tubers are characterised by a nice, smooth skin, shallow bud cavity and deep yellow flesh colour. Laura is an excellent cooking quality variety, suitable for processing into French fries.
Soil
Laura is moderately demanding in terms of soil and water supply, but is best grown in well cultivated soils with a good soil condition and a constant water supply. Soils with a very high risk of spot infestation (internal rust spots, -Dohan-Csrattle virus infection) should be avoided if specific control measures are not implemented.
Planting
Laura usually has a good initial development. After planting, it usually shows no signs for longer than usual, but thereafter it develops a rapid canopy, catching up. Careful germination stimulation before planting is beneficial to improve initial plant development. Laura's tuber fixation rate is medium-high, so the recommended number of tubers is about 44,000-47,000 tubers/ha if high yielding 40-60 mm tuber size table potatoes are desired. For processing into French fries or producing large-sized table potatoes, the recommended number of tubers per ha is 39000-42000. These recommendations are valid for tubers of 35-55mm grade and good water and nutrient supply. Different planting densities should be selected depending on environmental conditions.
Nutrient replenishment
The nutrient supplementation of Laura N can generally be applied according to the local standard. Our experience has shown that 160 kg N/ha (including soil Nmin) fits Laura's needs. Quantitative distribution of the N application: at least 2/3 of the total amount should be applied shortly after planting, with the second application at the latest shortly before flowering or tuber setting. Under certain environmental conditions (e.g. very sandy soil and high irrigation intensity), it may be necessary to modify the N application. In some locations, there is a tendency (tendency) for too late husk maturation, and N supplementation should be reduced in order to improve and enhance husk maturity. In particular, late N application (after the start of flowering) should be avoided! A balanced K supply ensures tuber quality. In soils with medium K supply, Laura requires 210-260 kg K2O/ha. In order to ensure good dry matter content, especially for potato processability, K supplementation with potassium sulphate is preferable. In the case of table potato production, K supplementation can be increased (about 25%) to reduce the susceptibility of tubers to mechanical damage and bruising.
Plant protection
Seed tubers should be treated with appropriate fungicides (similar active substances such as Pencycuron, Tolclofos-methyl, Fluotolanil, Fludioxonil) to control Rhizoctonia solani, in order to ensure high yield quality and high marketable yield. Laura is sensitive to herbicides with the active ingredient Metribuzin (SencorR , MistralR LexoneR, etc.) and postemergent (stock treatment) applications should be avoided! In cases where postemergent application is unavoidable, Metribuzin herbicides should only be applied under suitable environmental conditions (good waxy layer of foliage, not earlier than 2 days after the last rainfall, temperature between 12-22Co). Laura is somewhat resistant to potato late blight (Phytophtora infestans), prevention should be considered in the routine spray programme, if the potato late blight warning system has given a warning chemical control should be started. If a potato blight warning system is not available, a preventive spray programme should be started shortly before row closure (full canopy) with appropriate fungicides. In the case of high humidity in the plantation, especially on cohesive and clay soils, potato cyst nematode control should be started earlier to prevent primary stem infection.
Harvest
Irrigation should be reduced as much as possible at the beginning of ripening and tuber maturity in order to prevent swelling and opening of lenticels (respiratory glands) and related problems. Desiccation (defoliation) is recommended to facilitate harvesting and ensure the quality of the crop. Harvesting should be carried out carefully, with adequate soil temperature.
