Agrotechnics
Site preparation for planting potatoes
Light sandy soil types are suitable for Riviera potatoes. The place is chosen sunny and sheltered from the north winds. This is necessary so that the snow has time to melt before planting, and the earth dries out a little.
The plot is prepared in the fall: it is cleaned of plant debris and debris. Then fertilizer is applied and dug up. Nitrogen fertilizers are the best choice for the Riviera.
The use of ash as fertilizer has a qualitative effect on the future harvest. In the spring, it is enough to loosen the soil and you can start planting.
It is undesirable to plant potatoes in the place where Solanaceae or sunflowers used to grow. Potatoes are responsive to the use of green manure (autumn sowing of legumes, cereals and buckwheat crops). The use of green manure is tantamount to the introduction of organic fertilizers.Virgin soil is a good choice for planting potatoes.
Preparing tubers for planting
It is advisable to take out the planting material ahead of time in a warm (up to 15 degrees) lighted place. Light is necessary for the greening of the tubers. Withstand 15-30 days until strong shoots appear (about 2 cm). Pre-germinated potatoes accelerate the appearance of the first shoots. For sowing, select healthy, not very large (30-70 gr.), Without mechanical damage and frostbite root crops.
Landing
The following planting scheme for the Riviera is recommended: the indents between the rows are from 60 to 90 cm, and between the holes - 35 cm. The planting potatoes are laid out in the holes with shoots up to a depth of 6 cm. Simultaneous application of organic fertilizers to the hole will have a good effect on the harvest. The ground should be warm (8-10 degrees) and humid. You can mark the rows with a lace.
Follow-up care
Riviera potatoes are a very unpretentious variety, but compliance with important conditions can accelerate growth and increase the quantity and quality of finished products. Sprouted potatoes will sprout in 8-12 days.
- Weeding - removing weeds, affects the yield of vegetables. Weeding (with simultaneous loosening of the soil) is carried out after the emergence of mass shoots of the plant;
- Harrowing or loosening of potato rows is necessary after watering or precipitation;
- Hilling is carried out two times. The first - when the tops reach a height of 15 cm, the second - after two weeks (just before flowering);
- It is advisable to fertilize 3 times: at the emergence of seedlings, in the phase of the fourth leaf and during flowering. Fertilizers are introduced in dry (during loosening) or liquid form (watering with diluted manure, spraying on leaves). Using mulch increases the efficiency of fertilizers;
- Watering. The Riviera does not need frequent watering. If wilting of tops is noticed, and the soil is dry to the depth of a finger, then this is an indication for watering. With increased precipitation, you can sprinkle dry mineral fertilizers on the soil.
