- Abstract
Kacholam (Kaempferia galanga L.) is an important medicinal and aromatic oil yielding crop of Kerala. A study was conducted in the College of Horticulture, Vellanikkara, Kerala to identify the role of potassium and secondary elements, viz., sulphur, calcium and magnesium, on the essential oil and oleoresin content of the rhizomes of kacholam. Twelve treatments including the package of practices recommendations of Kerala Agricultural University for kacholam, and combinations of the same with extra dose of potassium, sulphur, calcium and magnesium were applied in the crop in a randomized block design with three replications. Top dressing of sulphur and magnesium resulted in higher rhizome yields (8.56 and 8.24 Mg ha-1). Sulphur application also resulted in higher oleoresin and essential oil contents. Higher sulphur and calcium contents in rhizomes were related to application of these elements. Path co-efficient analysis revealed that the secondary nutrients play a decisive role in the development of oleoresin and essential oil in kacholam.
