Crop regulation treatments in guava like No Pruning (P1- Control), Pruning (P2) and four bio regulators namely NAA 250ppm (T2), Urea 15% (T3), Ethrel 500ppm (T4) and CCC 50ppm (T5) were used to regulate rainy season crop on 10year old L-49 guava plants during the year 2014-2015 at KRC college of Horticulture, Arabhavi (Karnataka). Pruning at 10-20 cm of shoot length proved to be most effective in getting very good quality fruits whereas pruning combined with bio regulators like NAA, Ethrel and Urea found significantly effective on quality parameter as compared to control combination of pruning and ethrel treated (P2T4). Plants recorded maximum TSS, TSS: acid ratio and minimum titratable acidity. Combination of pruning and urea treated (P2T3) plants recorded highest percentage of reducing non reducing and total sugars, highest ascorbic acid and pectin content was recorded in pruned plants with 250 ppm NAA treatment (P2T2) and highest total phenol was recorded in combination of pruning and ethrel treatment (P2T4). Skin color, color and appearance was not significantly affected by pruning and bio regulators but texture, taste and flavour, overall acceptability was significantly higher than control.
