Sow 30 gm of ginger, harvest 2 kg
Ginger can give high yield, if proper care is provided. But the rhizome should be Varada, Mahima or Rajatha which are ginger varieties produced in the Indian Institute of Spices Research at Kozhikode. The time to start monsoon-based ginger farming is nearing. It is better to begin ginger cultivation close to Vishu festival.
The land has to be ploughed thoroughly before farming. Later, make flowerbeds with 10-meter length, 1-meter breadth and 1 feet height. Length can vary according to the requirement. Two flowerbeds need to have a distance of 40 cm between them. Add 2 kg neem cake, 1 kg dried leaves and 4 kg worm compost in one flowerbed and also 75 grams of Phosphobacteria. If the cow dung powder is enriched with Trichoderma, the ginger can be saved from perishing.
Make holes in 25 cm distance in the fertilized flowerbed and sow the ginger seeds in 2-inch depth. Dip a ginger seed weighing 25-30 grams with 3-4 sprouts in Pseudomonas solution for 5 minutes and keep it under shade for half an hour. Then sow the seeds and sprinkle as much dried leaves as possible on top of the flowerbed and finally cover it with coconut leaves. This covering should be repeated after 60 days and 90 days of planting. Fertilization should be repeated after 60 and 120 days.
Once ginger is sprouted, row cow dung solution can be poured. A diluted mixture of germinated groundnut cake, cow dung, bone meal, and neem cake also can be used as a fertilizer. The soil in the sides of the flowerbed should be dug slightly and put it on top of the covering. As the ginger becomes more visible, the flowerbed should be maintained well. For edible purpose, ginger can be harvested since 6th month. For ginger seed, we can start harvesting from 8 ½ month.
