Abstract:

The maintenance of fiber quality standards is essential for growers to avoid the price discount. The expression of fiber properties genetic potential depends on complex interaction among crop management and growth environment. Changes on some management practices, e.g. on cultivation system and irrigation regime, could affect some fiber properties. This study addressed the response of fiber quality parameters to the interaction influences of cultivation system and irrigation regime. Effects of three row spacings, conventional (CR), narrow (NR) and ultra narrow (UNR), on eight fiber properties were studied under limited and normal irrigation regimes during two growing seasons. The decrease of row spacing significantly decreased some fiber quality parameters but differed between normal and limited irrigation regimes. The effect of decreased row spacing on most fiber properties was less negative under the limited irrigation regime than the normal one and in this case the significant differences between row spacings were mainly between CR and UNR. Of the fiber properties investigated, row spacing and irrigation regime influenced most the micronaire readings and less the fiber elongation. The effect of year was significant on six out of eight fiber parameters. Interactions of year × row spacing, year × irrigation and row spacing × irrigation were significant but variable among fiber properties.

Keywords:

Lint quality, fibre properties, row spacing × irrigation effects
