Initial flow rate (F) is positively and plugging index (P) and dry rubber content (Cr) are negatively correlated with yield in both the climatic regions. Maximum temperature (Tmax) showed a negative correlation and minimum temperature (Tmin) and Vapour pressure (VP) positive correlations with initial flow rate, whereas Tmax correlated positively with P and Cr ER -
