Special practices


Twice after 4 and 8 weeks of transplanting


Retain 4-5 shoots in standard and 8-12 shoots in spray cultivars


Remove lateral buds in standard and terminal bud in spray cultivars


Wire mesh, plastic nets, string or bamboo canes are used to support plants. Wire mesh or plastic nets having inner size of 10-15 cm squares are placed on the ground in three
layers, which are erected at 20, 35 and 50 cm above the ground level with the growing

String or rope is erected in three rows at the same distance along the rows. In pots
for standard cultivars single bamboo stick is used and in spray cultivars 3-4 sticks are
placed on the sides to protect the plant.


Soil should have 60-70 per cent moisture. Depending upon weather 8-10 irrigations of  2.5- 5 cm depth are required.


Three-four hand weedings are sufficient. Atrazine @ 1.0 a.i. per hectare is effective before transplanting

Harvesting Stages

Harvested for local market when two flowers have opened and others have shown
colour, while for distant market when 50% flowers have shown colour
