Khon Kaen 3, 94-2-200, new sugarcane cultivar for the Northeast

Abstract

Khon Kaen  3  is currently   relased as  a new sugarcane cultivar for the Northeast  and  a  hybrid between    clone    85-2-352  and  K  84-200.  It was named 94-2-200 in breeding   program for period of 1995-2007. It  had   totally   been   conducted   as preliminary,  standard, standard,  field   and    field  test   during  1995-2007,  Results   showed   that      for   35  experimental   plots     average   cane yield     of   plants   and    ratoons   cane   were  18.1  and   16.5 ton/rai,  respectively.   These were 25 and  28  percent  higher than    cultivar   Uthong  3  (standard  check). Average   commercial    cane   sugar  (CCS)  of  plant   and   ratoon   cane were   14.6  and   15.1   ton/rai,  respectively  and   they   were  not   significantly   different   from   Uthong  3  in   both   plant and   ratoon    canes.   This cultivar does   not   have   flower therefore, cane  weight  and   CCS   could    not   reduce   even though    in   late   season   harvest.  Khon   Kaen  3  is  suitable for   green   harvest    because   of   loose  leaf   sheath   and  easily  to  de-trash.   Good   tillering ability of   Khon  Kaen 3 and   quick  cover  their   land   of  leaves  would   reduce  cost for    weeding.  Khon   Kaen   3   is   moderately   resistant    to smut   and   red    rot   disease.  Loamy    sand   is   likely  a  high potential   soil  for  this   culture   and   about  400,000  rai  in  the   Northeast   were   occupied  in   2010. Row  spacing  of  1 to  1.5  m.  and   plant   spacing  of  12.5  to  25  cm   or  as   whole  stalk    which   was  cut   into  30  cm  length   are  officially  recommended. For  Korat  soil  series  and  late  rainy season   planting, 9-6-6 and  18-6-6 kg  per  rai  of  N-P<sub>2</sub> O<sub>5</sub>  -K<sub>2</sub>  O  are  also  officially  recommended  for  plant  and  ratoon canes, respectively. For  Satuk   soil  series  and  rainy  season planting, 18-15-9.5  kg  per  rai  of  N-P<sub>2</sub>  O<sub>5</sub>  -K<sub>2</sub>  O  are  also  recommended as  well  for  both  plant  and  ratoon canes.
