As it is short duration crop with low investment, it becomes popular crop of India. Marigold flowers are attractive in shape and color. It is widely adopted because of ease of cultivation. On basis of size and color, it has two main varieties, African Marigold and French marigold. Plants of French marigold variety are short while flowers are small in size compared to African marigold. Maharashtra, Karnataka, Gujarat, AP, Tamil Nadu and MP are major marigold cultivator in India. Dashera and Diwali are two festivals when demand for this crop is highest.

Soil-
il -It can be grown on wide range of soil. But it grows best on well drained fertile soil. Soil should be well drained as it cannot withstand in water logged soil. pH of soil should be in range of 6.5 to 7.5. Acidic and saline soil is not suitable for cultivation. French Marigold are grow best in light soil whereas soil with rich manure is best for African Marigold.
Climate-
Year round production is possible under tropical and sub-tropical conditions
Propagated through seeds.
Time of sowing
Sowing of marigold can be done round the year. In rainy season, do sowing in mid-June and Transplanting in mid-July. In winter, do sowing in mid of September and in mid-October, complete transplantation.
Seed Rate
600-800gm seeds are required for one acre land. When crop is 30-45days old carry out pitching operation. It means removal of terminal portion of plant. It help to make plant bushy and compact, also more number of good quality flowers with uniform size are obtain.
Seed Treatment
Treat seed with Azospirillum@200gm mixed it in 50ml of rice gruel before sowing.
Plough land and bring field to fine tilth. To increased fertility of soil, at time of last ploughing add 250q of Farm Yard Manure or well decomposed cow dung in soil.
Spacing
Prepared nursery bed of 3m x 1m size. Add well decomposed cow dung on it. Irrigated bed and keep it moist. Crushed well dried flowers and broadcast them on bed or sown in line. When seedlings attained height of 10-15cm, they are ready for transplantation. Transplant seedlings at 35 x 35cm for French marigold while 45 x 45cm for African marigold.
Sowing Depth
Broadcast seeds on nursery bed.
Method of sowing
For sowing use transplanting method.
Fertilizer Requirement (kg/acre)
| UREA | SSP | MURIATE OF POTASH |
| 70 | 100 | 53 |
Nutrient Requirement (kg/acre)
| NITROGEN | PHOSPHORUS | POTASH |
| 32 | 16 | 32 |
Apply basal dose of N:P:K@32:16:32kg/acre in form of Urea@70kg, Single Super Phosphate@100kg and MOP@53kg/acre for good growth. Fertilizer dose changes according to soil type. To give accurate fertilizer dose, do soil testing and apply fertilizer according to it.
Take weeding operation depending upon intensity of weed.
After plantation in field give irrigation immediately. Bud formation to harvesting is most important stage for irrigation. Water stress should not occurr at this stage. Avoid water stagnation in field. In April to June month frequent irrigation at the interval of 4-5 days is necessary.
130 – 150 days.
1)Mealy Bug: These are observed on leaves, stem and on young shoots. They secrete honey dew like substance and because of it, sooty mould developed on leaves and give black appearance.
If infestation is observed, take spray of Dimethoate@2 ml/litre of water.
2)Thrips: Discolouration of plant tissue is observed. Discoloration, rolling and defoliation of leaves is observed due to thrips infestation.
To know intensity of thrips, set up yellow sticky trap@20 for one acre. If infestation is seen, take spray of [email protected] ml/litre of water or Azardiractin@3 ml/litre of water.
1)Powdery Mildew: Patchy, White powdery growth appears on lower side of leaves. It parasitizes the plant using it as a food source. It commonly occurs on older leaves but it can be developed at any stage of crop development. In severe infestation it causes defoliation.
Avoid water logging in field. Keep field clean. If infestation is observed in field take Spray of water soluble Sulphur@ 20 gm/10Ltr of water 2 times with interval of 10 days.
2)Damping off: Moist and poorly drained soil causes damping off disease. It is a soil borne disease. Water soaking and shriveling of stem occurs. If it appears in nursery, the entire lot of seedling may get destroyed.
To control, Drench nearby soil with Copper oxychloride@25 gm or Carbendazim@20 gm/10 Ltr of water.
Depending upon variety use, marigold will be ready to harvest in 2 to 2.5 months. French Marigold ready for harvesting in 1.5 month where as two months required for African Marigold. Plucked marigold plants when they attain full size. Harvesting should be done either in morning or evening hour. Field should be irrigated before plucking of flower, it will help to maintain quality for longer period.
Use bamboo basket or gunny bags for packing of flowers. Then transport them to local or distant market. In rainy season fresh flower gives an average yield of about 83-93 qtl/acre where as in winter it gives 60-70 qtl/acre of yield.
18 t/ha. In rainy season fresh flower gives an average yield of about 83-93 qtl/acre where as in winter it gives 60-70 qtl/acre of yield.
L3 hybrid (cultivated for xanthophyll extraction).
Seeds and Sowing
Sown throughout the year. Seed rate is 100 g/acre. Seeds are sown in protrays and
20 day old seedlings are transplanted on raised beds at 90 x 22.5 cm spacing to
accommodate 44,400 plants/ha. Treat the seedlings with Pseudomonas fluorescens @ 0.5%
before planting.
Fertigation
Recommended Dose of Fertilizer (RDF) is 90: 90:75 kg NPK/ha. 75% RDF is applied
through fertigation [Water Soluble Fertilizer (WSF) application through drip irrigation]. Water
Soluble Fertilizers such as Polyfeed (19:19:19), Potassium Nitrate (13:0:45) and Urea (46%
N) can be used.
Biofertilizers
Soil application of 2 kg each of Azospirillum and Phosphobacteria per ha at the time
of planting. Biofertilizers are to be mixed with 100kg of FYM and applied.
Micronutrients
Foliar spray of FeSO4 0.5% + ZnSO4 0.5% on 30th and 45th day after transplanting.
Spray humic acid @ 0.2% on 30 and 45 days after transplanting.
Pests
1)Cut worms and Helicoverpa armigera: Spray spinosad 45 SC @ 0.75ml/lit.
2)Mealybug : Spray dimethoate 30 EC @ 2ml/lit. or fish oil rosin soap @ 25 g/lit.
3)Bud borer : Spray spinosad @ 0.75 ml / lit.
4)Thrips : Spray fipronil 5EC @ 1.5ml/lit.
5)Red spider Mite
Spray any one of the following:
Spray abamectin 1.9 EC @ 0.5 ml/lit.
Fenazaquin 10EC @ 2 ml/lit.
