Abstract :

Field experiment was conducted to determine the optimum maturity of the major sugarcane varieties (Saccharium officinarium L.)  with  high  sucrose  content  and  sugar  yield.  Six  levels  of  harvest  ages  (10,  12,  14,  16,  18  and  20  months) and four major varieties N-14, NCO-334, CO-680 and B52-298 which cover 90% of the area were used in a completely randomized block design with 6x4x3 factorial treatment arrangements. All data’s were collected at the end of each level of harvest ages. Analysis of variance (ANOVA) showed that harvest age significantly influenced quality  parameters  (brix,  pol,  purity  and  ERS)  and  yield  parameters  (plant  height,  cane  yield  and  sugar  yield)  (P<0.001). The important parameters of maximizing sugar yield and net revenue in relation to harvest date and crop age is expressed by t/ha/month as an index of time value of sugarcane crop. Considering the time value, increase in harvest age showed a negative impact on brix, pol, estimated recoverable sucrose, cane yield and sugar yield in the tropical area of Ethiopia. As a result high sugar yield was recorded at the early harvesting ages 12 and 14 months. However,  optimum  sugar  yield  was  recorded  on  12  months harvest  age  with  economically  acceptable  marginal  rates  of  return  178.13%.  Therefore,  adjusting  harvest  age  to  12  months  for  the  major  sugarcane  varieties  was   economically recommended to obtain optimum sugar yield with efficient time use at the tropical areas of Tendaho.
