The Royal Hill-Tribes Development Program, presently called 'The Royal Project', was inaugurated in the year B.E. 2512 (A.D. 1969),
following His Majesty the King's expressed desire to introduce the benefits of sedentary agricultural practice to the Hill-Tribes community
with introduction of substituted cash crops that, in some cases, may fetch higher market prices than opium. During the early stages of the project,
His Majesty encouraged the grafting of temperate climate peach scions to the stocks of local species of peach trees. The grafted trees bore
fruits that were improved in texture and taste and were hardy enough to withstand transportation to the markets.
