8. TransplantingManureandfertilizer
 Ready for transplanting in about 3-4 weeks
after showing.
 After the land is bought to a fine tilth, the
entire quantity of FYM or compost (25t/ha) is
incorporated in the soil
 Prepare ridge and furrows at 45 cm apart for
early verity and 60 cm apart for late variety.

11. Buttoning
Development of small
size of curds or buttons
while the plants are still
small. The leaf become
small that they can not
cover the heads.
Cause:
Transplanting of week
seedlings.
Inadequate supply of N
Poor quality seed
Hot and dry weather
Whiptail
Leaf blades do not
develop properly and
remain strap like in
several cases only
midrib develops
accounting for the
name “whip-tail”.
 Cause:
 Deficiency of Mo
occurring mostly in
acidic soil where
pH is below 5.00.

12. BrowningBlindness
 Caused by BORON deficiency.
 Symptoms:
Change in colour of foliage.
Downward curling of older leaves.
 Application of borax at the rate of 10-15 kg
per hectare.
 Blind cauliflower plants are those without
terminal buds.
 CAUSE: low temperature when plants are
small.

13.  Harvesting is done
when the curds are
compact and good
size.
 Grading is done on the
basis of size color and
variety
variety Per hectare (kg)
Early & medium 15,000-20,000
late 20,000-25,000

16.  Curds can be stored in the open for 2-3 days
in winter . Good curds can be stored in cold
storage for about a month at 0ºc with 85-

 BLANCHING: is method using to protect curd
from yellow colour after their exposure to sun.
 Cauliflower is the only crop in COLE crop in
which the intermediate stage of curding
lies between vegetative and reproductive
stage.
