Cabbage

INTRODUCTION
Until now, the cabbage crop production both in quantity and quality is still low. This is caused partly because the soil is nutrient poor, unbalanced fertilization, crop pests, weather and climate.
For that, PT. Natural Nusantara as a company that cares about the problems of agriculture and environmental preservation effort to help farmers in increasing production in quantity and quality and maintain environmental sustainability (3 - K). So that farmers can compete in the free market era.

PHASE PRE PLANTING
1. Terms grow
- Plants can be grown year-round
- Grow and produce well at an altitude of 800 m d.pl. upward, rainfall and air temperature enough rain 15o - 20o C.
- Type the desired friable soil, lightly textured or nest, and pH 6 to 6.5.

2. Soil and Water Management
- Remove weeds and plant debris to suppress soil-borne diseases such attacks roots swollen, soft rot, seedling damping, etc.. manner revoked and could be collected and burned or composted
- Do not plant cabbage plants continuously and do crop rotation
- Use of organic fertilizers (SUPER NASA), particularly in the dry season to increase water use efficiency

3. Land Preparation
- Land hoe and plowed as deep as 20-30 cm
- Give CAPTAN Dolomite or approximately 2 tons / ha if pH <> PHASE seedbed
- Media nursery consists of a mixture of soil and manure (compost) smooth with a ratio of 1:1 and added 100 g (1 sachet) - - - Natural GLIO to 25 kg of manure
- The seeds soaked in warm water + NASA POC dose of 2 cc / lt of water for 0.5 - 1 hour ago aerated
- Spread the seeds evenly and regularly then covered in banana leaves for 3-4 days
- NASA POC Spray once a week with a dose of 3 cap / tank
- Perform watering every day with yells
- Nursery open every morning until 10:00 and the evening starts at 15:00
- Observe the cabbage seed flour hairy disease (Peronospora parasitica) or caterpillars on the leaves first leaves, plucked and thrown away the infected leaves

PLANTING PHASE
1. Spacing
Spacing rare 70 x 50 cm or spacing of the meeting of 60 x 50 cm

2. Seed
Seedlings that have been aged 3-4 weeks has 4-5 leaves ready to be planted

3. Fertilization
Given daily basal fertilizer before planting with a dose of 250 kg / ha TSP, 50 kg / ha Urea, 175 kg / ha ZA and 100 kg / ha KCl.
Basal fertilizer evenly mixed and then given to the planting hole that has been given the manure, then covered again with soil.

4. Method of planting
- Make the planting hole with a drill spacing corresponding
- Choose a fresh and healthy seeds
- Plant seeds in the planting hole
- When sowing seeds directly in the tube is planted with banana leaves bumbungnya
- When sowing seeds in plastic polybags, polybags and keuarkan of new seedlings are planted
- When sowing seeds in raised bed along with the land grab about 2-3 cm from the rod as deep as 5 cm with solet (rotation system)
- After planting, watering the seeds with water to wet
- Cabbage can ditumpangsarikan with tomatoes by planting: 2 rows of cabbage 1 tomato lines. Tomatoes are planted 3 or 4 weeks before the cabbage

CROP ESTABLISHMENT PHASE PRA (0-49 DAYS)
- Watering is done every day in the morning or afternoon
- Fertilization follow-up performed at 28 days with a dose of 50 kg / ha Urea, 175 kg / ha ZA and 100 kg / ha KCl
- Spraying NASA POC 3-4 cap / tank plus HORMONIK 1-2 cap / tank done once every 1 week.
- Weeding (pembubunan tilling and soil) is done at ages 2 and 4 weeks
- Perempelan branches or side shoots done as early as possible so that the formation of the optimal interest
- Pests that attack in this phase include land Caterpillars (Agrotis Ipsilon Hufn.), Cabbage leaf caterpillars (Plutella xylostella L.), cabbage caterpillar crop (Crocidolomia binotalis Zell.), Striped caterpillar crop (Hellula undalis F.)
- Perform observation once every week against the pests began to cabbage age of 13 days. The highest populations occur in the early dry season
- How to control; collected and destroyed by mechanical, environmental sanitation.
- Plants that die young due to disease fall sprouts (Rhizoctonia solani Kuhn.) Repealed, then embroidered with a healthy new crop, add Natural GLIO in the planting hole.

PHASE FORMATION Crop (50-90 DAYS)
- Weeding by hand needs to be done until about a week before harvest
- Conduct more intensive observation of pests that damage is severe in this phase; Caterpillars Cabbage Leaf (P. xylostella) and cabbage caterpillar crop (C. binotalis), usually February March
- The attack of pests before harvest did not need to be controlled (chemical)

HARVEST AND POST HARVEST
- Cabbage is harvested after the age of 81-105 days
- The characteristics of cabbage ready to harvest when the crop leaves the outer edge at the top of the crop is curved outward and slightly purple in color, crop the inside is solid.
- At harvest diikursertakan two strands of green leaves to protect the crop
- Do not get a bruise or wound
- Observe disease Soft Rot (Erwinia carotovora) and Black Rot (Xanthomonas camprestris)
- The leaves of cabbage infected should be discarded.
