Effect of Different Sites and Dates of Sample Collection on Nitrogen Content in Chlorophytum tuberosum Leaves and Tubers

World Health Organization (WHO) has estimated that at least 80% of the world population rely on traditional systems of medicine for their primary health needs. These systems are largely plant based. The Indian Institute of Forest Management (IIFM), Bhopal under its conservation assessment and management plan (CAMP) studied status of some selected species of non-timber forest produce (NTFP) of Madhy Pradesh. Researches on amla (Emblica officinale), safed musli (Chlorophytum tuberosum) and chirongi (Bachanania lanzan) have led to a change in State Government policy. An effort was made to study the effect of different sites and dates of sample collection on nitrogen content in Chlorophytum tuberosum at Mandu. The percentage nitrogen content in the leaves at the time of final sampling was maximum at natural site S1 (1.42 percent). The interaction between site and date in the percentage nitrogen content of tubers was statistically significant.
