The present experiment was carried out to ascertain the effect of different crop regulation practices on quality parameters of guava variety G-27. The experiment consisted of thirteen treatment comprising chemical growth regulators (urea @ 10%, 15% and 20%, NAA @ 200; 400 and 800 ppm, 2, 4-D 20, 40 and 60 ppm) and cultural practices (pruning upto 10%, 20% and 30%) were applied during the course of investigation. These treatments were evaluated under randomized block design with three replications by adopting uniform cultural schedule during the investigation. The observation revealed that all treatments had significantly increased in total sugar percentage, reducing sugar percentage, vitamin C and sugar acid ratio and decreased in acidity percentage. However, non reducing sugar percentage was not influenced significantly. Among the treatments, foliar spray of NAA @ 800 ppm (T6) significantly recorded maximum total sugar percentage (7.91), reducing sugar percentage (5.48), Vitamin C (192.25 mg/100g pulp) and sugar acid ratio (28.47) than rest of the other treatments. However minimum acidity percentage (0.28) was also recorded under NAA @ 800ppm.
