Sommaire Partiel
An experiment entitled “Agro-techniques for Cultivation of Some Medicinal Plants” was carried out partly at Meerut College, Meerut and partly at Division of Seed Science and Technology, Indian Agricultural Research Institute (IARI), New Delhi. The lab studies were conducted for four years (2007 -2011) and the field experimentation was done during kharif seasons of 2008-09 and 2009-10 to find out cultivation technology of ashwagandha (Withania somnifera) and kalmegh (Andrographis paniculata) and other related parameters. Changing scenario of herbal market and expanding global trade has opened up a new prospective for Indian agriculture. Medicines are the second most essential requisite after food for mankind. Medicinal plants are the important sources of raw drugs. The demand on plant based therapeutics has increased many folds in both developing and developed countries. They are natural products, non-narcotic, having no side effects and are easily available at affordable prices. Due to huge demand of plantbased crude drugs, throughout the world, there is an urgent need to domesticate or cultivate the medicinal plants. For genuine quality material, cultivation of medicinal plants and harvesting them at the appropriate time is essential. Each medicinal plant species has its own demand for nutrients, water and other parameters. The cultivation practices as well as post-harvest technology plays an important role for successful plantations, storage and trade of these plants. But due to lack of systematic information on cultivation of medicinal crops, growers are reluctant to adopt such practices. Medicinal crop cultivation relies heavily on quality seeds. Seed quality is of vital, in its absence, expenditure of farmers on the other inputs viz., fertilizer and irrigation may be of little value. There are various seed quality parameters namely, seed germination, physical purity, genetic purity, seed moisture and seed health which are the pre-requisite for seed quality assurance. The Seeds Bill 2010 (proposed Seed Bill 2004) emphasizes fixing the minimum seed standards in respect of all categories of seed made available to the farmers. Such standards would protect the interest of the farmers by conforming to the minimum limits of seed quality parameters. Keeping view of their varied therapeutic potential, considerable economic value and need for cultivation and their seed quality parameters, the two experimental systems ashwagandha (Withania somnifera (L.) Dunal) and kalmegh (Andrographis paniculata Nees) were chosen for the present study
