Treat seeds with a recommended fungicide. Seed should be planted in beds 10-15 cm apart at the depth of 0.5 to 1 cm and cover with a thin layer of soil. Spread a layer of straw mulch over the beds and water daily. Remove the mulch when the germination is complete. Avoid exposure of seedlings to heavy rains and to prolong sunlight. Harden seedlings by exposing them to sunlight and increasing irrigation intervals for one week before planting. Seedlings are ready to transplant after 3-4 weeks.

Land preparation
