Summary, etc	In India more than 88 percent of rubber is grown in small holdings and their share in NR production is 87 percent. Above 90;area in small holding has the Indian wonder clone RRII 105. Though the tapping frequency recommended for this clone is 1/2S d/3 6d/7, more than 90;small holders follow higher frequencies. Due to the high frequency of tapping and associated incidence of TPD, economic life in small holdings is restricted to 13-15 years resulting ia a very high cost of production. Under d/3 frequency, crop realized fom RRII 105 is lower than optimum. Hence, mild yield stimulation (3/y) was recommended to optimize yield. On farm trials and lab to land programs of RRII in various locations are in agreement with the recommendation. Almost all small holders make payment of wages based on number of trees tapped irrespective of production. But, a newly introduced production linked incentive proved to be beneficial for both the tapper and the grower. Prolonged immaturity phase, 6-7 years (to attain tappable girth of 50cm) is also a problem in small growers field. Mini/reduced spiral cuts with appropriate yield stimulation can successfully be adopted for early opening (1-1 1/2 years early), when the trees girth is 43cm or more. The crop realized is more than 80;of standard (1/2S d/3) tree of 50cm girth, and with better girth increment. Adoption of mini/reduced spiral cuts for early opening, subsequent practice of d/3 frequency tapping with mild stimulation, and high panel exploitation under CUT (with periodic panel change) is ideal for small growers. This enables them to have longer exploitation, better production and to reduce cost of production, considerably. REsults of on farm trials, and problems faced in extending the new techniques are discussed.
