Rajasthan and to some extent in Punjab. Alkaline saline soils with pH range of 8-9 are quite suitable for the growth of rose plant. considerable assistance has been derived ffom testing experience of fragrance and flavour industries. An International Standard ISO 9842:2003 ‘Oil of rose (Rosa damuscena Miller)’ also exists. For the purpose of deciding whether a particular requirement of this standard is complied with the final value. This plant flowers during the month of March and April in North Indian Plains and May and June in hilly areas. the main areas of its cultivation are located chiefly in Uttar Pradesh. Morocco.
