Abstract Design and development of equipments to cut crop plant materials require some basicdata to avoid waste of energy on a wide range of area In this research the effect of someplant and blade factors on specific cutting energy SCE requirement to cut sugarcanestalks was investigated using pendulum method A pendulum like apparatus wasdesigned and calibrated SCE in this research means energy requirement per area per drymatter d m density of section of cut j g cm 1 Blade factors included velocity and knifeangles while plant factors included moisture content cane cutting position from node orinternode and maturity degree by one month of time difference A 3 replicates factorialexperiment with completely randomized design CRD layout was conducted The resultsshowed that minimum SCE of 0 21 j g cm 1 of dry matter was obtained with a minimumvelocity of 1 33 m s p 0 05 minimum moisture content of 48 p 0 01 and also withlower degree of maturity p 0 01 Knife angle and cutting position node or internode had no significant effect on SCE while interaction between them with moisture contenthad significant effect on SCE p 0 01 Furthermore interaction between maturity degreewith cutting position and also with knife angle had significant effect on SCE P 0 05
