Forecasting Model of the Yield Elements for Cotton |
| |
| Abstract: | he number and weight of the cotton bolll per plant were main elements which causes the yield variation of cotton. Combining the field observations with climatological statistics,the bud numbers per plant,the matural boll percentage and the boll weight of cotton were predicted first. Then the final cotton yield as forecasted. The accuracy of the yield forecast model was improved. |

| Keywords: | cotton yield\ matural boll percentage\ boll weight\ yield forecast |
