Therefore, the seed propagation is the most preferred method over cuttings. However, you can follow the later one method for maintaining the purity of varieties

Nursery Raising

Prepare the nursery beds by digging area and incorporating well rotten FYM. Before sowing the seeds, you will need to drench the soil should with Captan to avoid the ants, which carry away the seeds. Additionally, you must maintain a seed rate of 400 -600 g/ha.

Transplantation

You can transplant one-month-old seedlings with 3 -4 true leaves. However, you must avoid thin & long seedlings and too old seedlings. Transplanting should be done in well-prepared land and soil is pressed around root zone to avoid air pockets. After planting, you must provide a light irrigation.

Regular picking improves the yield. The yield highly depends on the cultivation practice, far management, and variety. With proper management and care, you can expect 125-150q/ha yield for African marigold and 80-120 q/ha in French marigold cultivation.
