Development of agronomic and varietal options for dry season cotton production in NW Australia.

Date Issued:1996-08-16

Abstract

High yields (> 11 b/ha) were achieved with varieties adapted to hot arid growing conditions. However, fibre lengths were lower than for the same variety grown in southern Australia; cool nights early in fibre development were thought to be the cause. Screening for varieties that can produce longer fibre is continuing. March - April sowing dates produced the highest yields. Progress was made in determining nitrogen fertiliser rates and plant densities. Integrating results from agronomic research with pest management research and developing recommendations for the use of growth regulators are future priorities.
