Despite the fact that marigold flowers are available all year, there is still a desire for them. Marigold is a popular flowering plant in India and around the world since it blooms for a long time and is easy to grow. Marigold is planted on a total area of 66.13 thousand hectares in India, yielding 603.18 million tonnes of output.
Marigolds can be grown in a variety of soil types. Loamy ground with good drainage, on the other hand, is regarded good for its production. Whose pH level should be between 7 and 7.5.
Temperate and temperate climates are favourable for marigold production. Too much heat and too much winter are thought to be harmful to plants. It should be produced at a temperature of 15-30 degrees Celsius.
Land preparation for the nursery
For the nursery, a high location should be used. There should be enough drainage, and the nursery should be located in an area that is not shaded. The soil where the nursery will be planted is levelled, then a 7 metre long, 1 metre wide, and 15-20 cm deep trench is dug. The seeds are subsequently sown in high beds that have been built according to the requirements.
There are two different varieties of marigolds.
- Bolero, Redhead, Goldmam, Butter, Dustilal, Flamingfire, Flame, Orangeflame, Suncrest, and other French species are prevalent.
- African Species: Pusanrangi Marigold, Pusabsanti Marigold, GoldenCoin, Stargold, Golden Age, Deuce Spun Gold, Happiness, Space Age, Moonshotsmile, and other species are well-known.
Plant preparation time
The sapling should be prepared at the following period to ensure marigold production throughout the year.
- Summer season: – Seeds should be sown in the nursery in February-month to get flowers in May-June.
- Autumn: In order to have flowers in November and December, the seeds should be planted in the nursery in August.
- Spring season: – In order to have blossoms in August-September, the seeds should be planted in the nursery in May.
For a one-hectare plant, 800 grammes to one kilogramme of seed is required.
Sapling transplantation: When the plant is 30-35 days old or has 4-5 leaves, it should be transplanted. Planting should always take place in the evening. The dirt around the plants should be compacted by hand after transplantation. After transplanting, a light irrigation should be performed right away.

Depending on the species, the planting distance varies. In general, the space between marigold plants is 30-35 cm. metres, while the distance between lines is 45 cms. Keep the metre running.
Manure and Fertilizer:
To produce good marigold production, place 150 to 200 quintals of fully decomposed cow dung in the field 10 to 15 days before ploughing the field and apply 160 kg nitrogen, 80 kg phosphorus, and 80 kg potash. Half of the nitrogen, as well as the whole amount of phosphate and potassium, should be mixed in the soil before transplanting, with the remaining nitrogen sprayed in the standing crop after about a month.
Irrigation should be done with the moisture content of the field in mind. Irrigation should be done every 6-7 days in the summer and every 10-15 days in the winter.
To keep marigold free of weeds, weed control with a headhoe and scabbard should be done on a regular basis.
This is an extremely important work in the marigold crop. The top bud of the plant should be clipped by 2-3 cm when the marigold crop is about 45 days old. The metre should be cut and removed to let more buds to form in the plant, resulting in more marigold blooms.
Flowers should be plucked once they have fully bloomed. The finest times to pick flowers are early in the morning or late in the evening. Light irrigation should be done in the field before plucking flowers to keep the flowers fresh. The thumb and finger should be used to pluck the blooms in such a way that the plants are not damaged.
African marigold produces 18-20 tonnes per hectare, while French marigold produces 10-12 tonnes per hectare.
Pest control and major diseases
Diseases of major importance:
Humidity drop: This is a sickness that primarily affects nurseries. Seed germination is limited in nurseries impacted by this disease, and plant stems begin to wilt. In hot, damp soil, this illness spreads quickly.
1. To suppress it, seed should be treated with Captan at a dosage of 3 grammes per kilogramme of seed before sowing.
2. Infected plants should be removed from the nursery and discarded.
Powderymildew is a fungus. The leaves of the plant infected with this illness turn white, and minute spots emerge on the leaves, eventually covering the entire plant in white powder.
1. To control it, a medicine called Sulphex is sprayed after preparing a 3 gramme per litre water solution.
2. Remove the unhealthy plant from the field and bury it in the dirt.
Pests of major importance include:
This is a highly dangerous marigold insect. This bug is more prevalent during the blossoming season. This insect feeds on the juice of marigold leaves and sensitive stem parts.
1. Make a 0.2 percent Malathion solution and spray it to control it.
This insect eats marigold leaves, causing them to wilt.
1. A 15 percent solution of an insecticidal dust called Telaldehyde should be used to control it.
