Planting and Harvesting

Patala seeds are sown immediately after removing the wings. They are placed at room temperature under a mist house, an ideal condition for germination. The Patala seeds shoot up within six to twenty days, and the seedlings sprout within eight to fifteen days. When seedlings are 4 cm in height, they are then transplanted in polybags with sand and cow dung, in the ratio of 2:1. Plants remain in polybags for approximately eight months before planting in fields till the next rainy season. Seedlings are then planted in pits of 30 cm X 30 cm X 30 cm at a distance of 10 m. Weeding and mulching are done twice a year. The plants are given an adequate amount of water during the summer season. In the early developing stage, several branches appear. But only one leader branch is allowed to grow while the rest of the branches are trimmed. The roots of the Patala plant can be harvested every five years. For post-harvest management, the roots are dried in a shed and stored in gunny bags. Flowering occurs at the beginning of the summer. The flowers bloom for around a month.


Medicinal plants are valuable sources for herbal products used globally. The slow growth of medicinal plants will result in the exhaustion of their resources. Cultivation of such plants is required to ensure their availability to the people and industries producing medicines. Such cultivation not only protects the endangered species, but also provides an alternative economy for the poor farmers. We at Jaivik Farms, an agro-based organization, encourage the farmers to cultivate medicinal plants like Patala. Our team of experts is always ready to guide the farmers to practice good harvesting techniques and cultivate the plants organically, that is, without the use of any pesticides or chemicals.
