Cultivation Of Cauliflower

By Punjab Agricultural University on 28 Jan 2016 | read


Climate and Soil

Cauliflower grows well on wide range of soils from sandy loam to clay. The optimum pH is between 6.0 and 7.0. Cauliflower is a thermosensitive crop and temperature plays an important role influencing vegetative, curding and reproduction phases of plant. The optimum temperature of growth for young seedlings is around 23' C which at later growing stage drops to 17-20' C. The tropical cultivars grow even at 35' C, however, temperate cultivars grow well between 15' C to 20; C.

Improved Varieties

Late Season

Pusa Snowball-1 (1994) : Outer leaves are upright and inner leaves cover the curd initially. Curd is compact, medium sized and snow white. Curd is ready for harvest in about 100 days aftertransplanting. Curd yield is 90 q/acre.

Pusa Snowball K-1 (1994) : Outer leaves are upright and inner leaves cover the curd tightly. Curd is compact, snow white and slightly raised in the center. The maturity is late by one week than PusaSnowball-1. Curd yield is 90 q/acre.

Agronomics Practices

Sowing and Seed Rate : The best transplanting time is June July for the early varieties, August to mid-September for the main season varieties and October to first week of November for the late season varieties. The seed rate for main and late season varieties is250 g per acre, whereas, for early season varieties 500 g seed is required. To check bolting and buttoning, sow the recommended varieties at their proper time. To minimize mortality of early sown nursery and transplanted crop, apply heavy dose of well rotten farmyard manure and irrigate frequently. Protect seedlings in the nursery beds against sun stroke with sarkanda thatch. Transplant seedlings in a cool‘wattar’ field in the afternoon and irrigate immediately.

Spacing : The spacing for the main-season crop is 45 x 45 cm.and 45x30 cm for early and late-season crops.

Manures and Fertilizers

40 tonnes of farmyard manure, with 50kg of N (110kg of Urea),25 kg of P2O5 (155 kg of Single Superphosphate) and 25 kg of K2O(40kg of Muriate of Potash) per acre is the optimum fertilizer dose forall these varieties. Apply whole of farmyard manure, P2O5 and K2Oand half N before transplanting and the remaining half of N as topdressing four weeks after transplanting.

Weed Control : Apply Basalin 45 EC (fluchloralin) @ 750 mlper acre 4 days before transplanting the seedlings. Herbicide should be thoroughly incorporated into the soil with the help of light harrowing.It should be supplemented by one hoeing after 30-40 days of transplanting. Stomp 30 EC (pendimethalin) 1 litre/acre or Stomp 30EC 750 ml followed by one hoeing 35 days after transplanting can also be used. Stomp should be applied one day before transplanting of the seedlings in the moist soil conditions.

Irrigation : First irrigation should be given just after transplanting.Subsequent irrigation can be given at an interval of 7-8 days during summer and 10-15 days during winter depending upon soil type and weather. The total number of irrigation required are 8-12.


The curds should be harvested at the marketable stage. Delaying harvesting causes loosening of the curd. The curds should be sent to markets in baskets after proper grading and packing.

Seed Production

For seed production crop is grown just like market crop. After curd formation seed of early and main season varieties can be produced in the plains, however, the seed of late season varieties can only be produced in the hills because during flowering and seed setting stage moderate temperature is available in the hills. To produce genetically pure seed, the off-type plants must be removed thrice during vegetative phase, curd formation stage and flowering stage. Isolation distance of 1600 meter should be kept between different Cole crops and different varieties of cauliflower. When pods turn brown they should be harvested two or three times. After curing they should be thrashed and cleaned.
