Advantages and disadvantages
Every vegetable crop has its advantages and disadvantages. Cauliflower Koza-Dereza has the following advantages:
- simultaneous ripening, which makes it possible to harvest several crops per season;
- high yield;
- stable fruiting even in adverse weather;
- resistance to temperature decrease;
- pleasant taste;
- good head binding.
Among the shortcomings, vegetable growers note the susceptibility of the Koza-Dereza variety to diseases and pests, but with proper care, these problems can be avoided.
Productivity of cauliflower variety Koza-Dereza
The average yield is 3,2 kg per 1 m² of area (with a planting density of 4 pcs per sq.m). When growing in several visits from the site, you can harvest several times more.
Ripening time depends on the climatic conditions of the region and the date of planting:
- March-April – 55-65 days;
- April-May – 50-60 days;
- June-July – 53-69 days.
Planting and caring for cauliflower Koza-Dereza
Gardeners practice two ways of growing cauliflower: seedling and seed. According to their feedback, the first method shows great efficiency, since climatic conditions in Our Country are quite unpredictable.
To obtain seedlings of cauliflower Koza-Dereza, seeds are sown in March or early April. After about 30-40 days, seedlings will grow to 15 cm in height, 4-5 true leaves will appear on them, and they will be ready for transplanting.
The optimal distance to be left between adjacent holes is 50 cm, between rows – 45 cm. Well-lit beds are chosen for planting. Cauliflower Koza-Dereza does not tolerate shade, so it will not be possible to harvest under the crowns of trees.
Cauliflower seeds Koza-Dereza must undergo pre-planting treatment. They are wrapped in gauze and dipped in a weak solution of manganese, then kept until pecking in a damp cloth. For wetting, you can use Epin, succinic acid or any biostimulant. Before planting, the seeds are treated with Fitosporin or another biofungicide. It is enough to hold the seed material in the preparation for 15 minutes.
Algorithm for obtaining seedlings of cauliflower Koza-Dereza:
- Seeds are best planted in individual containers (peat cups), this will avoid picking and transplanting. Cabbage has very fragile roots, so their injury negatively affects the growth of the crop. 3-4 seeds are sown in a container, and after germination, they are culled, leaving the most powerful of them.
- The soil is used store-bought or self-prepared. For these purposes, humus, peat, sand, earth are mixed (in equal proportions). For 1 liter of soil add 1 tsp. wood ash. The earth is sterilized by keeping it in the freezer for 24 hours, you can pour it with a 5% solution of manganese.
- Before planting, the soil in containers is moistened. Cauliflower seeds are deepened by 0,5 cm, sprinkled with sand on top. To create a greenhouse effect, glass is installed on the containers or a film is stretched. A five-minute airing is carried out every day.
- Until the first sprouts appear, the containers are kept in a dark place at a temperature of 22 ° C, when the seeds sprout, the air in the room is cooled to 10 ° C during the day, and to 6 ° C at night. After a week, the temperature is increased to 16°C. Additional lighting is carried out with phytolamps, the daylight hours for cauliflower Koza-Dereza is 12 hours.
- Watering should be regular, but waterlogging of the soil should not be allowed.
- Top dressing of cauliflower seedlings is carried out twice: after the appearance of two true leaves and after 2 weeks. Rostock, Kemira-Lux and others are chosen as nutritional preparations.
- 1-2 weeks before planting in the ground, seedlings begin to harden off. She is taken out into the street, first for a few minutes, then the residence time is increased. In the last 2 days, the seedlings spend the night in the fresh air.
A cloudy day is chosen for transplantation. Dig holes to a depth of 10 cm, moisten the soil well. At the bottom you can put 1 tsp. superphosphate and a little onion peel, sprinkle with humus. The pungent smell of onions will help prevent the invasion of pests.
If using the seed method of planting in the ground, it is necessary to wait for the soil to warm up to 12 ° C. In a temperate climate, the approximate planting time is the first ten days of May, in the southern regions – the end of April. 2-3 seeds are planted in each hole, sprinkled with a layer of sand on top. The area with cabbage is covered with a film. After germination, the film is replaced with spunbond or lutrasil. Seedlings are under cover for up to 35-45 days.
When growing cauliflower Koza-Dereza, the following rules are followed:
- Watering is very important, especially at the time of formation of inflorescences. Seedlings are moistened 1 time in 2-3 days, using at least 7 liters per 1 m². For cabbage at the age of 1 month, the number of waterings is reduced to 1-2 times a week, but the volume of water is increased to 12 liters per 1 m². After sunset, you can additionally use sprinkling.
- The first time after planting top dressing is carried out after 10 days. Then the nutrients are applied at intervals of 15 days. For the first feeding, nitrogen is used, then phosphorus-potassium mixtures. Browning and crumbly heads indicate a lack of boron and molybdenum. A spray solution consisting of ammonium molybdate and boric acid (1 g per 1 liter of water) will help correct the situation.
- The beds are loosened 2 times a week. The roots of cabbage are superficial, so the procedure is carried out carefully, deepening by 7-8 cm.
Diseases and pests
Cauliflower Koza-Dereza has good immunity to diseases, but it is often attacked by insects.
Insects do not tolerate pungent odors, therefore, to protect cabbage, garlic, mint, lavender, and marigolds are planted around the perimeter of the beds.
For cauliflower Koza-Dereza, the following pests pose the greatest threat:
- Cabbage aphid. Herbal infusions will help get rid of the invasion of insects; tobacco, mustard, garlic, potato tops can be used for their preparation. Spray infected plants several times a day. If there are too many pests and folk remedies are powerless, Aktara, Biotlin or other chemical agents are used.
- The cabbage fly lays eggs, from which larvae emerge. They damage roots and stems. Prevention consists in planting parsley and celery around the beds. For processing, you can use soapy water or a solution of vinegar essence (1 tablespoon per 10 liters of water). From store funds, Fufanon, Tanrek are suitable.
- Cruciferous flea damages foliage. You can get rid of insects with an infusion of garlic, tobacco, red pepper. Trichlormetafos, Lightning, Furadan, Karate Zeon, Aktara, Kaiser and other chemicals are also used.
- Scoop caterpillars eat foliage. Homemade traps filled with sweet water or diluted jam help to eliminate insects. Of the drugs, Actellik, Lepidocid, Confidor-Maxi are effective.
- Slugs can also eat leaves and flowers. You can scare them away with a solution of mustard powder. Pine needles, crushed eggshells are poured around the seedlings, which prevents slugs from moving around the beds. From chemistry they use Thunderstorm, Slug Eater.
For cauliflower Koza-Dereza, the following diseases are dangerous:
- root rot;
- mucous bacteriosis;
- hernia;
- Alternaria;
- downy mildew;
- Fusarium wilt.
When identifying root rot, Trichodermin, Gliocladin are used. Mucous bacteriosis leads to rotting of inflorescences; to prevent planting diseases, they are treated with Pentafag or Mikosan. If significant damage is detected, the cabbage is removed from the garden and burned.
It is very difficult to get rid of the keel. If damaged specimens are found on the site, they are removed, and the land is used to grow other crops. Cauliflower is planted in this area no earlier than after 7 years.
Alternariosis occurs during extreme heat and high humidity. For prevention, dusting the beds with crushed chalk is used. You can treat with Baktofit.
Fusarium causes deformation of the inflorescences and yellowing of the foliage. To prevent the occurrence of this disease, it is necessary to add Fitosporin to the water for irrigation.
To prevent peronosporosis, the plants are sprinkled with wood ash, and the ground with crushed chalk.
Application
Cauliflower Koza-Dereza is used for cooking various dishes. It is fried, pickled, salted and frozen.
Conclusion
Cauliflower Koza-Dereza is in demand among vegetable growers. The early ripeness of the crop allows you to harvest 2-3 crops per season. Cabbage heads are universal in use, various dishes are prepared from them, the inflorescences are closed for the winter and frozen.
