2 EFFECT OF MONTH OF REAPING ON YIELD OF SUGARCANE By Orphiel Brown Sugar Industry Research Institute Kendal Road, Mandeville

3 Introduction Present methods of cane prediction are unscientific Result in grave disparity between actual and estimated yields This paper does not seek to present a model for cane estimation Instead it seeks to determine if the month of reaping of a cane field affects its subsequent yield

4 Data  Obtained from CYS Database  December to June for 2 estates  10 years to 1998  No lower limit *  Upper limit of 160 tc/ha for yield  January to June for all others  Plant cane omitted  Assumed to be normal

5 Analysis done by ? Estates/Farms ? All island ? Ecological Areas -Irrigated -Rain-fed

6 Method of Analysis/Presentation  ANOVA with Month as a factor  Chart of MEANS with LSD intervals

7 Results  ANOVA is highly significant  Rapidly declining yields except Worthy Park and Cambria  Highest yields when reaped between December & March

8 Yield vs Month of Reaping - Appleton

9 Yield vs Month of Reaping - Frome

10 Yield vs Month of Reaping - Monymusk

11 Yield vs Month of Reaping - Bernard Lodge

12 Yield vs Month of Reaping - Long Pond

13 Yield vs Month of Reaping - Hampden

14 Yield vs Month of Reaping - Tropicana

15 Yield vs Month of Reaping - Worthy Park

16 Yield vs Month of Reaping - Cambria

17 Yield vs Month of Reaping - Irrigated Areas

18 Yield vs Month of Reaping - Rainfed Areas

19 Yield vs Month of Reaping - All Island

20 Conclusions/Recommendations  Month of reaping does affect subsequent cane yields  To obtain yields > 65 tc/ha, reap fields between December and April, inclusive  Do not extend cropping time beyond April

21 THE END
