Preparation of land
For transplantation of gladiolus, it is necessary to cultivate the soil well before sowing. The soil must be finely broken and well flip over. Generally, Gladiolus cultivars require 3-5 kg of roasted cow dung or organic manure, 5 grams of urea, 1 gram TSP and 1 gram MOP per square meter. During the last cultivation, TSP, MOP and cow dung should be mixed in the soil. Half of the urea fertilizer should be applied 24-20 days after planting and the remaining half after flowering.

To
increase the sowing depth, sow the tubers at 7 cm depth.
The method of sowing
Sow directly by maintaining proper spacing on tubers or rows.
Seeds
Seed rate
per acre Use Karam 6250067000. Before sowing the
seed treatment, the

The gut of roots is rotten nematodes
Symptoms are stagnant growth, thinning leaves and leaves turning yellow and swelling of roots.
Medical
Nematodes are sprayed on infected fields with oxamyl solution.
Mosaic virus

If insects are seen, Acephate @ 1 gram is sprayed in 5 liters of water per acre .
Aphids
Aphids destroy the growing new part of the tree.
Medical
Flowers are sprayed with Rogor 1 EC or malathion 1 EC @ 1 ml / liter of water during flowering to get rid of aphids .
Thrips
Thrips eat away the leaves and flower buds of the tree.
Medical

Cut the bulb
After 3-5 weeks of flowering, the carmes and caramel should be cut. Irrigation should be stopped in the field 2 to 3 weeks before harvest. After harvest, the worms are dried with air. Remove the leaf from it and clean the worms. Then the tubers were submerged in 0.2% Bavistin solution for half an hour . After dipping, they are dried in shade for 2-5 weeks. After drying, they are stored in plastic bags in cold storage at 4 ° C.
Processing after harvest
Freshly cut flowers are deposited in a card board box. Sell these boxes as soon as possible to the nearest markets or flower vendors.
