Abstract：To increasethe yieldand improve the qualityof passion fruit，this studyappliednine treatments（T1- T9）combining diferent urea applicationratesandpruning intensities in2O21and 2O22 inLongyan City，Fujianprovince. Sixteen traitsrelatedtothegrowth，flowering，fruiting，yieldandqualityof pasionfruit weremeasured，andvarianceanalysis andvariationanalysis werecariedout.Then，comprehensiveevaluationof T1-T9 treatments wasobtainedbycorelationanalysisand principalcomponentfactoranalysis.Theresultsshowedthatall16traitswereafectedbyT1-T9 treatments，and the variation coefficients ranged from 1.11% to 29.01% . There were nonsignificant （ P>0.05 ），significant （ P< 0.05）or extremely significant （ P<0.01 ）correlations among the 16agronomic traits.The first two principal componentswith eigenvalues greater than 1.OOo were selected by principal component analysis，andtheir cumulative variance contribution rate was 84.129 % ，which represented most of the original data information and centrally reflected theyield andqualitycharacteristics ofpassion fruit. Accordingly，acomprehensive evaluation model wasestablished as Y=0.807Y1+0.193Y2 .Based on the comprehensive score ranking，T6 treatment demonstrated the bestoverallperformanceintermsofagronomictraits（growth，floweringandfruiting），aswellasyieldandqualityofpassion fruit.Therefore，the combination of 192kg/hm2 urea application rate and heavy pruning can be considered in passon fruit production in Longyan City，Fujian province.
