Abstract

An ethnobotanical inventory was conducted in the rural areas of Kannauj districts, Uttar Pradesh during 2007- 09 following standard ethnobotanical methods for documentation of underexploited, non-conventional, traditional and indigenous wild vegetables for further studies leading to sustainable utilization of these resources to overcome malnutrition in vegetarian diet. During present study 25 species belonging to 18 families have been documented. Chenopodium album is the most common and popularly used wild vegetable followed by Ipomoea aquatica and Coccinea grandis in the study area. Seven species are reported as wild vegetable for the first time in India. Leaves and young stem are used in majority of the cases. Only 56% wild vegetables used in the study area are easily available, it means 44% wild vegetables are threatened to be lost if not conserved properly. The highly endangered wild vegetables in the study area are Abrus precatorius, Centella asiatica, Dioscorea bulbifera, and Solanum incanum.

The primitive men, cultivation is not practiced and market supplies are through trial and error, have selected many wild not organized, local inhabitants depends on edible plants and subsequently domesticated them indigenous vegetables either cultivated by (Kar, 2004). However, many wild vegetables themselves or collected from wild (Mishra et al., traditionally consumed by local communities are 2008). The traditional knowledge about indigenous underutilized. The nutritional value of these wild wild vegetables is largely transmitted by oral vegetables is high in comparison to commonly tradition from generation to generation without any cultivated vegetables (Nordeidet al., 1996; Sundriyal written record. Such practices are still prevalent and Sundriyal, 2001; Orech et al., 2007). The wild among rural and tribal communities in many parts of vegetables are an important source for the the world (Haridarshan et al., 1990; Samant and supplementation of micronutrients in vegetarian diets (Nordeid et al., 1996; Agate et al., 2000; Odhav Received 18 March 2013; Revised 20 May 2013; Accepted 21 et al., 2007).

The name Kannauj is traditionally derived following formula (Kumar et al., 2013): from the term Kanyakubja (maiden's womb). Kannauj is an ancient city, in earlier times it was the capital of a great Hindu kingdom. It is said that Kanyakubja Brahmins are originally from Kannauj.

Caesalpinaceae Ethnobotanical surveys and collection of data and Solanaceae are the highly represented families Survey of rural areas of Kannauj district, Uttar (Figure-1). Various Parts of Basella alba, Boerhaavia Pradesh was conducted during 2007-2009 to collect diffusa, Chenopodium album, Ficus hispida, Ipomoea information regarding wild vegetables and voucher aquatica, Polygonum glabrum, Rumex dentatus, and specimen. Prior to survey, a questionnaire was Solanum incanum are reported as wild vegetable for designed and pre-tested with five informants to find the first time in India. Chenopodium album is the out its suitability for present study and modified most common and popularly used (9.83%) wild according to response of informants. The revised vegetable followed by Ipomoea aquatica and questionnaire was used for gathering data about non- Coccinea grandis in the study area (Table 1). Leaves conventional and underutilized wild vegetables of and young stem are used in majority of the cases the study area (Appendix A). Field works were (68%) followed by fruits (18%), flowers and tubers conducted in randomly selected ten villages. Total (7%). Only 56% wild vegetables used in the study 50 informants having age of 30 to 65 years were area are easily available, whereas, 28% are available interviewed during present study. Information’s with difficulty and 16% are hardly available in natural regarding the local names of plant species, growth resources, it means 44% wild vegetables are forms, part(s) used, availability in natural resources, threatened to be lost if not conserved properly. The method of processing and vegetable preparation, highly endangered wild vegetables in the study area method of collection, storage and conservation needs are Abrus precatorius, Centella asiatica, Dioscorea were carefully recorded.
