ABSTRACT

This study monitored growth and development of cotton grown under different cropping systems at the Edisto Research and Education Center, Blackville SC. Conventional monocropped cotton was compared to cotton interseeded into standing wheat (which was later harvested), cotton planted after wheat harvest (wheat/cotton doublecrop), and cotton planted into wheat cover crop (which was killed with Gramoxone). The conventional monocropped treatment with fall deep tillage had the highest yield, whereas the doublecropped cotton, which was planted the latest, had the lowest yield. One of the interseeded treatments and the wheat cover crop treatment produced approximately the same yields which were not significantly different from the yield of the conventional monocropped treatment that did not have fall deep tillage. This paper discusses the root and above ground development, as well as node length and boll location.
