Cauliflower Cultivation

Sowing, Nursery and Transplanting

Before the cauliflower seed are sown it is very important to prepare the nursery with optimum growth conditions. Generally for one hectare of cauliflower seedling, a nursery of 100 sq m is enough. A protected nursery is to be created where half of the nursery should be covered with shade nets and the sides covered with 40/50 mesh insect proof nylon net.
The seeds are sowed in portrays for seedling formation should be conveniently spaced. In order for germinating the seeds, it requires a specialised growing medium which is formed by mixing sterilized cocopeat @ 720kg/ha with neem cake of 10kg and 1 kg each of Azospirillium and Phosphobacteria. The portrays are filled with the cocopeat mixture and the soil preparation and seeds are sown.The portrays are than kept on top of each other and are covered with material like polythene or dry grass so that it gives optimum water only. After that within 5 days the germination starts and the grass or polythene cover can be removed once the sprouts starts to grow. In order to protect the small early seedling from high temperature and rain, it should be covered and shaded. After seeds are germinated, the portrays are arranged on raised bed in the nursery. It is important to water the trays everyday and also drench with 19:19:19 + MN in the ratio of 5g/l. Within 3 – 4 weeks the transplants are ready. In early crop the seeds are sown in May to June and late crop seeds sown in September to October in nursery. For mid crop or main crop seeds are sown in July to August.

Seed Rate

The seed rate depends on the season. In case of early crop an average requirement is 600 to 700 gm/ha and for late crop requirement is 450 to 500 gm/ha.

Seed Treatment

There are various ways to treat the seeds before sowing them. It is important to treat the seeds so that it gives high mortality rate and better productivity.
