Continuing the attempt to understand the properties of the stellar content in the young cluster NGC 1893 we have carried out a comprehensive multi-wavelength study of the region . The present study focuses on the X-ray properties of T-Tauri Stars ( TTSs ) in the NGC 1893 region . We found a correlation between the X-ray luminosity , L _ { X } , and the stellar mass ( in the range 0.2 - 2.0 M _ { \odot } ) of TTSs in the NGC 1893 region , similar to those reported in some other young clusters , however the value of the power-law slope obtained in the present study ( \sim 0.9 ) for NGC 1893 is smaller than those ( \sim 1.4 - 3.6 ) reported in the case of TMC , ONC , IC 348 and Chameleon star forming regions . However , the slope in the case of Class III sources ( Weak line TTSs ) is found to be comparable to that reported in the case of NGC 6611 ( \sim 1.1 ) . It is found that the presence of circumstellar disks has no influence on the X-ray emission . The X-ray luminosity for both CTTSs and WTTSs is found to decrease systematically with age ( in the range \sim 0.4 Myr - 5 Myr ) . The decrease of the X-ray luminosity of TTSs ( slope \sim -0.6 ) in the case of NGC 1893 seems to be faster than observed in the case of other star-forming regions ( slope -0.2 to -0.5 ) . There is indication that the sources having relatively large NIR excess have relatively lower L _ { X } values . TTSs in NGC 1893 do not follow the well established X-ray activity - rotation relation as in the case of main-sequence stars .
