When growing turmeric on a raised bed, the method of setting up the bed and the minimum tillage method must be considered. Beds that are 15cm in height, 1m in width and length may be prepared and there must be spacing.
In essence, it means that the elevated structure of the line of intersection between the side of the roof of the raised bed and the ploughed land is subjected to a special process while the rhizomes are planted in a very low area or at the top of the ridge.
Generally, the spacing is 4.5–6.0 cm separated from the ridges and 1.5–2.0 cm between the turmeric plants.
This method makes use of heat energy directly from the sun to reduce the signs and effects of pests, diseases, and soil-borne diseases.
It is important to note this because it helps in checking up on the diverse and endless pests and diseases that affect turmeric plants in the raised beds.
The sheet, commonly known as polythene, is used for the solarisation of the soil.
In growing turmeric, it is important to considerably preserve turmeric seed (rhizomes) free from destructive pests and diseases, which are most often gotten from organic farms used solely for planting.
To whatever degree or extent you wish to start with, seeds gotten from high-flourishing local varieties can be used in the need for organic turmeric seeds. For sowing, both the rhizomes and the fingers are used.
What are Rhizomes which Have Been an Occurring Word in this Article?
Turmeric is a rhizome (root) that has its origin in the ginger family (zingiberaceae), a native of India.
As they progress, the fingers are sliced into sections of 4-5 cm in length while the mother rhizomes are grown and bisected into two, with each piece having one sand bud. Sometimes, the seed grows under a moist straw before sowing.
What are the irrigation requirements for growing turmeric in a raised bed?
It all depends on the nature and health of the soil, as well as the climatic conditions for a reasonable number of turmeric irrigations.
Depending on the type of soil and rainfall, 15–25 irrigations are given on medium-heavy soil, and in rare cases of light-textured soil, 35–40 irrigations are needed.
Manures and Fertilization Requirements
Predominantly healthy and good seeds from turmeric bring a flourishing output, especially when the farmers use natural fertilizers and animal compost or dung.
For growing turmeric in your raised bed, farmers are advised to avoid using chemicals and pesticides that are harmful. Turmeric requires enrichment of the raised bed by heavy manuring.
Controlling Pests and Diseases in Turmeric Growing
There is no diverse disease found in turmeric like in other plants that encounter different types of pests and diseases.
Leaf blotch and spot are the most common diseases found in turmeric and can be controlled by reducing the use of Bordeaux mixture by 1%.
It is advisable to apply Trichoderma at the specific time of planting to act as a check when encountering issues of rhizome rot. If the shoot bearer becomes significant in your turmeric plant, the shoot should be cut open, picked out and finally left aside.
How Can I Harvest My Turmeric in a Raised Bed?
The harvesting period of your turmeric extends from January to March and then to April. Early matured turmeric becomes ready for harvest in 8–9 months while the medium takes 7-8 months.
The signs that show the crops are matured for harvesting are that the leaves will completely turn yellow and begin to dry up, looking very frail.
At this point, leaves are cut close to the surface of the soil. The raised bed is then used as an implement to turn over soil, especially in seedbeds, while rhizomes are gathered by picking them carefully.
Note that the medium rhizomes are carefully and thoroughly cleaned while the mother and finger rhizomes are separated before curing comes into place.
What is the yield of turmeric after growing it in raised beds?
The yield of turmeric varies because the harvesting of turmeric is done by skilled laborers, whose demands are always very high. It is estimated to have a high yield based on the plant spacing and nurturing.
What Is the Best Month for Planting Turmeric?
The best months are September and October, so it can grow and mature for harvesting at the right time.
When planting turmeric, it should be planted 5-7 cm deep. Most of the time, it is planted on ridges, usually 30–45 cm apart and 15–30 cm in between plants.
This is done to achieve proper growth and harvest of the turmeric. I believe I have been able to teach you how to grow turmeric in your raised bed.
