Onions are sown in the nursery before being transplanted in the main field.
Dimensions of Nursery beds should be 3’x10’ and 10-15 cm in height while keeping a distance of about 70 cm between the two beds.
When onion nursery is being prepared, the ease of weeding, irrigation should be kept in mind.
In areas of heavy soil, the height of the bed should be kept high enough to avoid the problem of waterlogging.
Before sowing, treat onion seeds with CARBENDAZIM 12% + MANCOZEB 63% @ 2.5gram/ kg seed or CARBOXIN 17.5%+ THIRAM 17.5% @ 2.5gram / kg seed.
Soil treatment of nursery is very necessary before nursery sowing treatment is done for prevention of soil borne diseases. For this use FIPRONIL 0.3% GR @ 10 kg / nursery and TRICHODERMA VIRIDE @ 25 gram / nursery and seaweed + amino + Mycorrhiza @ 25gram / nursery
In this way, the seeds should be treated and the field should have sufficient moisture at the time of sowing.
