Features agrotehnika
Like most Dutch varieties, prone to degenerationtherefore, seed material is regularly updated.
With an independent renewal of the stock of planting tubers during flowering, they notice the strongest, abundant flowering bushes.
The consumption of seed tubers with a fraction of 35-55 mm for planting per hectare is 50,000 units.
Before planting, the tubers are germinated, spreading out in a bright warm place for 3-4 weeks. All tubers should be uniformly lit at least 8 hours a day. Indoors maintain optimum humidity of 85-90%.
Large tubers are cut into pieces with a sharp knife dipped in a strong solution of potassium permanganate the day before planting. Planting material is selected with sprouts 0.5-1 cm.
Planting is made in the soil warmed up to + 15-20 ° С under the scheme of 60x35 cm. Planting tubers are placed sprouts up, slices - cut down.
When cultivating observe crop rotation. In large areas, yields increase after perennial and annual grasses, cereals, winter crops, flax, colza, fratselia, and rape.
To improve the agrophysical properties of heavy, clay soils in the autumn digging add river sand, wood ash. When re-spring digging make ammonium nitrate or ammonium nitrate, urea (10 g / m²).
With the close occurrence of groundwater Ramon is better to plant in the ridge. This will increase the access of oxygen to the root system, reduce the defeat of tubers by fungal diseases.
Agronomists recommend to orient the landing ridges from east to west. So the potatoes get more sunlight.
On loamy, heavy soils, the tubers are planted in holes 6-8 cm deep. The depth of embedment into sandy, sandy soils is 8-10 cm. To prevent the drying of tubers in areas with arid climate increase depth up to 12-15 cm
For the entire growing season Ramone up to five loosening required. When a soil crust is formed, before the emergence of shoots, the soil is gently mocked. Spud 2-3 times in the summer.
Potato varieties "Ramona" forms tubers and with low soil moisture. In a drought, one-time irrigation between rows for 7-10 days is enough.
To improve product quality during flowering, ripening tubers plants support with nitrogen or organic supplements. When spraying the bushes while tying the buds with 0.05% aqueous solutions of copper sulfate, zinc sulfuric acid, boric acid, the yield increases by 8-10%.
Despite the average yield, "Ramona" caught on domestic fields due to unpretentiousness, drought tolerance, good disease resistance and the Colorado potato beetle, excellent taste.
