Turmeric (Curcuma longa) is a
tropical rhizomatous crop
cultivated most extensively in
India, followed by Bangladesh,
China, Thailand, Cambodia,
Malaysia, and Indonesia.
Turmeric has a high demand for
potassium and yield production
generally responds to increased
soil fertility. The quantity of
fertilizers required by the crop
depends on the variety selected, as
well as soil and prevailing weather
conditions during crop growth.
*Potassium is a vital nutrient for turmeric as it
1. Ensures higher rhizome yield by
• Increasing tillers,
• Primary and secondary rhizomes and
• Weight of rhizomes
*Potash fertilized turmeric plant * No potash
2. Enriches quality of rhizomes (higher curcumin content).
* Potash fertilized
steamed turmeric
rhizomes exhibiting
yellow colour.
3. Reduces severity of pests and diseases attacks.
Potash use on turmeric
• Turmeric is a heavy feeder of nutrients
• Increasing rates of potassium application had a positive and
significant effect on fresh rhizome yield
• Field experiment exhibited that potash application at 260 kg ha-1
over control (No Potash) resulted in a more than
� 2.5 and 4 fold increase in yield of cured rhizomes and
curcumin content
� Registering potassium uptake of rhizome @ 151 kg ha- 1
* Potash applied K6 (260 kg ha-1
) No potash –K1

Potash recommendations for turmeric crop.
Muriate of potash (MOP) which
has 60 percent potash content is
good source of potassium for
turmeric crop. Application of
potash fertilizers 260 kg ha-1
, 120
kg of N ha-1
(urea), 50 kg P2O5 ha-1
(superphosphate), 5kg ZnSO4ha-1
,
and 5 kg Fe SO4 ha-1
along with farm yard manure @ 25 t ha-1
is a
good practice on Inceptisols.
