Precision Farming Of Cabbage

i. Quality seedling production

Protected nursery

 The nursery area is covered with 50 per cent shade net

 The raised beds of 1 m width and convenient length are formed

 The seedlings are raised in portrays

 The sterilized cocopeat @ 720 kg/ha is mixed with 10 kg of neem cake andAzospirillum and Phosphobacteria each @ 1kg. About 1.25 kg of the cocopeatmedium is filled in each tray.

Sowing

About 250 g of hybrid cabbage seed is required for the production of seedlings for 1 ha. The seeds are treated in hot water @ 50ºC for 30 minutes.

The seeds are mixed with Azospirillum @ 100 g / kg and are shade dried for halfan hour. About 25 g of Azospirillum is required for the seed treatment of 250 g cabbage seeds.

Sowing of cabbage seeds in protrays is done @ 1 seed per cell. The seeds are covered with cocopeat and is kept one over the other (8-10 Nos.) and covered with polythene sheet for 5 days or till germination starts.

After 5 days when the seeds are germinated the protrays are arranged on the raised beds inside the shade net nursery.

Watering is done by rose can everyday (twice / day) up to seed germination.

Panchakavya spray @ 3% (30 ml/lit) is done at 15 days after sowing.

9:19:19 + MN @ 0.5 % (5 g/lit) solution are drenched using rose can or micro nutrient spray of 0.5 % is done at 18 days after sowing.

The cabbage seedlings are ready for transplanting in 25 days

ii. Planting

The main field is ploughed 4 times using chisel and disc each at one time and cultivator two times.

FYM @ 25 t /ha is applied before the last ploughing.

75 % of the total recommended dose of super phosphate i.e. 588.93 kg is applied as basal dose.

Azospirillum and Phosphobacteria each @ 2 kg / ha along with FYM 50 kg and Neem cake @ 100 kg is applied before last ploughing.

Raised beds of 120 cm width are formed at an interval of 30 cm and the laterals are placed at the center of the bed.

Drip irrigation is done for 8 to 12 hours depending upon the soil moisture level and soil type.

Pre-emergence weedicide spray of Fluchloralin @ 1 lit a.i./ha or Trifluralin 0.5lit/ha through high volume sprayer is done just before transplanting. Ropes are marked at the interval of 45 cm and planting is done at the spacing 45 x 45 cm in the paired row system.

Gap filling is done at 7th day after transplanting.


iii. Fertigation Techniques

Fertigation requirement for cabbage F1 hybrid is 200: 125: 150 kg of NPK/ha is applied once in every three days throughout the cropping period.

iv. Inter cultivation

Carbofuron @ 33 kg/ha is applied at one week after transplanting to control nematodes.

Foliar spraying with Pseudomonas fluorescens @ 0.5 % (5 g/lit) at 15 daysinterval is done for 6 times.

Weeding is done on 30 DAP depending upon the weed growth.

Micro nutrient mixture @ 21 g/lit (0.1%) is sprayed at 40th, 60th and 80th DAP.

v. Harvesting and Post Harvest Management

Harvesting is done when the heads attain the full size and are firm.

The harvested heads are packed in the collapsible crates and are transported to market without damage.
