It requires SKUAST-K, Shalimar, Srinagar, minimal irrigation, mostly during critical stages prior to flowering. Currently, saffron is faced with a J&K, India number of challenges, especially outside Iranian region. The few prominent ones are lack of good-quality corms as seed material, poor soil fertility, lack of assured irrigation, increased urbanization on saffron land, and rampant adulteration. Initiatives are needed to reverse the declining trend by its cultivation in non-traditional sites like in arid as well as semi-arid regions. Instead of spending huge amount on large irrigation projects for big areas especially when financial resources are a constraint, a good alternative strategy is introduction and popularization of organic saffron in kitchen gardens. This would ensure small-scale cultivation as it would be easier to assure irrigation during critical growth stages, and hence supply of good quality genuine saffron for in-house consumption, and also increase awareness about organic agriculture. Herein we present a first report on the establishment of organic saffron kitchen gardens by women in their households, and successful cultivation of saffron in non-traditional semi-arid trans-Himalayan regions of Kashmir valley. Keywords: Crocus sativus L., vegetable, semi-arid, non-traditional, ethnobotany, health, geographical indication, climate change Introduction Saffron (Crocus sativus L.) is the dried orange-red trifid stigma of a perennial bulbous plant Crocus sativus L., a triploid male-sterile plant flowering in autumn, one of the costliest culinary spice of the world [1]. It is included in the family Iridaceae. Some recent research reports indicate two possible sites of saffron origin: one in Greece in the Mediterranean area, and the other at East in Turkey-Iran-India [2]. Highly coveted for its beauty, aroma, healing [3] powers, and overall appeal, “Red Gold” is the most expensive spice in the world . Its production is typically favoured in countries where labour is cheap, such as Iran, India and Azerbaijan, but is also produced in countries like Greece, Switzerland, Spain, Argentina or the USA and newer areas being brought under its cultivation, viz. China and Japan [4]. Jammu and Kashmir, which encompasses the western Himalayas and the Karakorum mountains is well known for best quality saffron (Crocus sativus L. Kashmirianus) (reviewed [5,6] in Husaini et al. ). It is the only high-altitude saffron in the world that is cultivated at 1600- 1800 m above mean sea level, and this could be one of the major contributors towards its unique characteristics and good quality. The major characteristics that constitute its uniqueness are its longer and thicker stigmas, deep-red colour, great aroma, bitter taste and chemical free processing. It is a traditional niche plantation crop of Kashmir, where it has been under cultivation since past twenty five centuries. There had been a long pending demand for granting it the status of Geographical Indication for Kashmir Saffron on a pattern similar to that for Spanish “Azafrán de la Mancha”, Greek ‘Krokos Kozanis’, and Italian "Zafferano dell'Aquila" [6]. Its connection with the Indian soil can be illustrated by the fact that in the ancient Saffron language it is known by the name ‘Bahukuma’, and as ‘Kesar’ in Hindi, ‘Zafran’ in Urdu and ‘Koung’ in Kashmiri. Its distinction as being reflected in its scientific name ‘Crocus sativus L. Kashmirianus’ [5, 6] is supported by its genetic distinction.
