title: Relevance of Vṛkṣāyurveda and other traditional methods for organic production of nursery seedlings of useful plants.
abstract: Plant propagation is critical to augment the resource and has been the main concern for farmers and planters through history. India has evolved the science of Vṛkṣāyurveda to address the above issue. An effort is made here to review Vṛkṣāyurveda literature related to nursery techniques. Different libraries were visited and relevant review material obtained by hand search and from databases. Interaction with Sanskrit scholars and eminent scientists working in the field of Vṛkṣāyurveda, as well as the efforts of the authors of this paper, helped in the selection of pertinent literature. In the absence of original texts, authentic translations of the publications were referred. A conscious decision was made to limit the search to the fields of seed storage, pretreatment and nutrition of seedlings. To have a comparative account recent trends and literature on nursery technology were also examined. This was supplemented by interviews with traditional organic farmers. Our survey revealed that the time period of the literature pertaining to Vṛkṣāyurveda ranges from BCE 1200 to the present times. The subject has evolved from morphological descriptions and uses of plants, in texts such as Ṛgveda and Atharvaveda, to treatises dedicated solely to the art of growing plants like Kṛṣi-Parāśara and Vṛkṣāyurveda. It is also evident that there were important periods when more works appeared across subjects such as water divining, soil types, seed collection and storage, propagation, germination and sprouting, watering regimen, pest, and disease control. The review revealed that valuable information pertaining to nursery techniques is available in Vṛkṣāyurveda, which can be used in the development of nursery protocol. This will not only help in effective organic nursery management, but also ensure the health and livelihood security of the communities involved and effective waste management.
