Farmers in the Chamba district of Himachal Pradesh, keen for new livelihood options to supplement their income from traditional crops like maize, paddy, and wheat, have found a new lease of life.
Cultivation of aromatic plants has given them additional income. They are extracting essential oil from the improved variety of wild marigold (
Tagetes minuta) that has been introduced, and the profit from wild marigold oil has doubled the income of farmers as compared to traditional maize, wheat and paddy crops.
The improvement in the fortune of the farmers has been brought about through interventions made by Society for Technology and Development (STD), Mandi Core Support group, SEED Division, the Ministry of Science and Technology said in a statement.

Dr Vijay Gahlaut of the Himalayan Bioresource Technology, Palampur, is working on developing a wheat strain that can grow even in high temperatures. He is trying out DNA methylation technique adding a methyl group (which is a methane molecule in which a hydrogen atom is replaced with another compound) to the DNA to develop a wheat variety that is heat-tolerant.
His research falls under a science called ‘epigenesis’, which means altering gene activity without changing the DNA sequence, an alteration that can be passed on to daughter cells. This research is significant in the context of global warming farmers may not lose productivity if temperatures rise.
