Being the third important stone fruit crops of India, apricot still requires a great improvisation in production point of view. Bio-regulators are being used by the growers to increase the yield by improving the yield attribute parameters. Keeping the objective to increase the yield, in the recent studies; twenty six-year-old apricot cv. New Castle trees were subjected to 11 treatments viz. Forchlorfenuron (CPPU) at 5 and 10 ppm and N-acetyl thiazolidine 4-carboxylic acid (NATCA) at 50 and 100 ppm and their combinations were applied at pink bud and petal fall stage during the year 2015 and 2016. The experiment was laid out in completely randomized block design with three replications in the experimental fruit orchard of Department of Fruit Science, Dr YSPUHF, Nauni, Solan. Out of the two time of spray the petal fall stage was found to be superior in both the years. Foliar spray of CPPU at 10 ppm increased the fruit size was attributed by the increased fruit length (29.88 mm), breadth (30.51 mm), weight (16.20 g) and volume (14.93 cc). Keeping all the observations in consideration CPPU 10 ppm at petal fall stage was found to be best among all the treatments.
