Gladiolus Crop Information

Post-Harvest

Freshly cut flowers are stored in card board boxes. These boxes are sold to nearby markets or to flower sellers.

Harvesting

Harvesting is mainly done after 3-4 months i.e. 90-120 days of transplanting. Harvesting is mainly done by retaining at least 4-5 basal leaves of the plant for adequate development of corms and cormels. It gives an average yield of 1 00,000 spikes/acre and 95,000 corms/acre.

Tuber harvesting: After 6-8weeks of flower harvesting, corms and cormels should be harvested. Stop irrigating the field 2-3 weeks before harvesting. After harvesting the corms are air dried. Clean the corms by removing the leaves from it. After drying they are stored in plastic bags in cold storage at 5-10oC.
 

Mosaic virus: The symptoms are yellowing, stunted growth, mottling and ring spots are seen.

Treatment
: There is no treatment once the plant gets infected but before infection rouging of infected plants, weeding and controlling insect vectors will help to prevent mosaic virus.
 

Thrips: The thrips affect the plant by feeding themselves on sap of leaves and flowers.

Treatment
: Spraying of Malathion @4ml/ltr of water is done to get rid from thrips.
 

  • Pest and their control:

Aphids: The aphids destroy the growing young parts of the plants.

Treatment:
Spraying of Rogor 30 EC or Malathion 50 EC @3ml/ltr of water is done at the time of flowering to get rid from aphids.
 

Root knot nematode: It is caused by Meloidogyne incognita. The symptoms are stunted growth, wilting and yellowing of foliage and galling of roots.

Treatment:
Treatment with oxamyl solution is given to the infected fields.
 

Hard rot: It is caused by Septoria gladioli. The symptoms are dark brown or black color and sunken lesions are appearing on the corms.

Treatment: Dip the corms in Thiophanate methyl solution at 85-120oF temperature or in iprodione at suitable temperature for 15-30 minutes to get rid of corm rot.
 

Plant protection

  • Disease and their control:

Corm rot: The symptoms are premature yellowing of leaves, stem collapsing and reddish brown color dry rot on corms.

Treatment: Dip the corms in Thiophanate methyl solution at 85-120oF temperature or in iprodione at suitable temperature for 15-30 minutes to get rid of corm rot.
 

Fertilizer

Fertilizer Requirement (kg/acre)

UREA
SSP
MOP
120 185 30

 

Nutrient Requirement (kg/acre)

NITROGEN PHOSPHORUS POTASH
55 30 18

 

Before 20 days of seed sowing, mixed FYM @5kg/ m2 in the soil. At the time of land preparation, apply fertilizer dose of Nitrogen @55kg (Urea@120kg), phosphorus @30kg (Single superphosphate@185kg) and potash @18kg (MOP@30kg) as a basal dose. At 5-6 leaves stage, application of nitrogen is done @30gm/m2.

Weed Control

Hand weeding or weedicide spray is done to control weeds. Hand weeding should be done once in fortnight for weed control. Use of Atrazine @500gm/acre or Pendimethalin@600-800gm/acre as pre-emergence spray or use of Paraquat@600-800ml/acre or Glycel@800ml/acre is used as post emergence spray for weed control. Do not spray Paraquat and Glycel on the main crops, because it is harmful for the main crop. Apply only on weeds.

Deficiency and their remedy

Iron deficiency: Yellowing of leaves are the symptoms of iron deficiency in the Gladiolus crop. Spraying of ferrous sulphate @1kg/acre should be done when seedling has 3-6 leaves is done to cure iron deficiency. 

Irrigation

From mid-September to end-March, irrigation is given twice a week with running tap water and from start-April to End-June irrigation is given thrice a week and then from start-July to mid-September irrigation is given after 15 days interval depending upon weather conditions.

Seed

Seed rate:
Use 62500-67000 corms for per acre land.

Seed treatment:

Before sowing tubers are dipped in Bavistin solution for one hour and then it is shade-dried to protect them from soil-borne diseases.
 

Sowing

Time of sowing:
Low hills:
July-August, September-October
Mid hills: February-March, May
High hills: April-May

Spacing:
Use row to row spacing of 25cm and the distance between tubers should be 15cm for intensive cultivation and for normal cultivation use spacing of 45X45cm.

Sowing depth:

For good growth, sow tubers at depth of 8cm.

Method of sowing:
Tubers or corms are sowing direct in the soil at a proper distance in rows.
 

Land Preparation

For gladiolus plantation, land should be well ploughed before sowing. To bring the soil to fine tilth, ploughing must be done. Application of FYM@20-25tonnes is mixed with the soil.
