Growing Cauliflower-Planting to Harvesting

The complete steps of Growing Cauliflower-Planting to Harvesting are described very clearly here. you will get all about planting to harvesting such as soil condition, Climate requirement, Varieties, Raising of seedling, Manuring and fertilizer, Land Layout, Transplanting, Intercultural operations, Yield etc.

Growing Cauliflower-Planting to Harvesting

Introduction

  • Cauliflower, Brassica oleracea
  • Member of the Brassicaceae family
  • Bangladesh is one of the densely populated countries in the world and its population is increasing day by day at the rate of 1.7%
  • Vegetables are the major source of minerals, vitamins and phytochemicals
  • Even more that 30,000 people get blind at childhood every year due to deficiency in vitamin A
  • According to the FAO recommendation amount of consumption of vegetables is 200 gm/day/person but the average intake of vegetables in Bangladesh is only 45 g/day/person
  • about 100 species of vegetable crops are usually grown in Bangladesh
  • Bangladesh cauliflower is generally grown as winter season crop and harvested from September to late-February or early-March
  • It is closely related to broccoli, cabbage, turnips and mustard
  • The word cauliflower comes from Latin terms caulis meaning stem, stalk or cabbage; and floris meaning flower
  • Cauliflower has been an important crop in this country since 1920 and is used as fresh vegetables.

Soil and Soil Conditions

  • All types of soil also capable to grow Cauliflower in with good fertility and good water regime
  • The optimum PH for cauliflower is 6.0-6.5
  • The limit of salt tolerance is rather lower than cabbage

Climate requirement

  • Cauliflower tends to be more exacting in its climatic requirement than the other member of the Brassicaeae
  • Therefore, it has been established that between 150C and 200C the growth would be optimum for most of the temperate cultivars

Varieties

  • V1= Advanta-403
  • V2= Advanta-410
  • V3= Advanta-413
  • V4=White snow
  • V5= White marble
  • V6= Tropical Eleven

Plant Characteristics & Morphology of the Curd of Cauliflower

Height: 45 cm – 60 cm

Spread: 60 cm- 90 cm

Root Depth: 45 cm – 90 cm

Raising of seedling

  • Seeds of all the 6 varieties were sown in seed bed
  • Bed size was 2.50 m X 1.10 m
  • In 26.09.11 to raise cauliflower seedlings
  • Proper nursery practices were followed to raise healthy seedlings

Land preparation

  • Soil were prepared well and brought to a fine tilth before transplanting
  • While preparing, the manure and fertilizer were applied as basal dose
  • The size of the beds and the number of rows to be planted
  • Channel and drain were made
  • The size of beds may vary from large one carrying 3-4 rows to single or double row beds

Manuring and fertilizer

  • The recommended fertilizer for cauliflower cultivation is given below:
Fertilizers Quantity (ha)
Urea 250 – 300 Kg
T.S.P 150 – 200 Kg
MoP 200 – 250 Kg
Cowdung 15 – 20 tons

Land Layout

  • In the main plot the experiment was laid out in RCBD design with 3 replications.
  • Unit plot size was – 2.20m X 1.30 m

Transplanting

  • 31 days old seedlings were transplanted on 27.10.11
  • Transplanted at the depth of 3-5 cm (15 days old)
  • In each plot 15 plants were placed
  • Irrigation was done after transplanted by watering cane

Intercultural operations

  • Irrigation

Cauliflowers requires 5-6 times irrigation

Medium to heavy rainfall occurred during this experiment

Irrigation was done for 2  times in this study

Weed control

  • Weed attracts harmful insects
  • Competitor of plants for nutrients
  • Damage 60% to 80% of production by weed
  • Two weeding system were done in this study

– At 10 days after transplanting

– Next is 35 days after first weeding

Mulching

  • Mulching had beneficial effects on yield
  • To be beneficial in increasing the growth and yield of cauliflower
  • The maximum return was obtained with mango leaves used as mulching

Harvesting

  • The curds are cut off the stalk with a large, sharp knife
  • To cut the curd immediately it reaches prime condition
  • When transporting, loose, more jacket leaves should remain than when packing in crates

Yield

  • The  highest yield was Advanta-403 variety
  • Because of its more compact curds and larger plant population per unit area
  • The yield of this variety was 20.97 tons/ha
  • The lowest yield was Tropical Eleven (9.50 tons/ha)

Conclusion

Through this experiment on Growing Cauliflower-Planting to Harvesting an attempt was made to identify a good quality cauliflower F1 hybrid from the seeds supplied. After a thorough research as well as careful study under the present investigation it was found that Advanta-403, was superior than other varieties may be recommended as a suitable variety.
