摘要：

Seed cotton samples were collected in a field from which yield maps had been taken in the previous three years. The samples were analysed in a High Volume Instrument (HVI) automatic machine to assess the lint quality. Thematic maps of the lint properties are presented. Correlation analysis was performed between yield fibre and soil properties. A general trend showed a negative correlation between the yield and most of the lint properties. Lint quality correlations with soil properties were significant in many cases. Factors like pH, Ca, Mg and organic matter affect fibre quality. Yield correlation to soil properties was significant only with penetration resistance and soil Mg content.
