Aims: * Determine the economic impact of thrips on cotton and evaluate new means of control. * Evaluate the range and possible mechanisms of plant resistance to thrips and mites.

Objectives: A). To establish the uptake and partitioning patterns of potassium in cotton. B).

The effects of rotation crops and their management on soil properties, and irrigated cotton productivity and profitability were evaluated from 1993 to 1996 in some typical cracking clays (V ertisols) of the Namoi and

The objectives of this study were to: l) determine the role of soil instability and clay translocation in the formation of shiny-faced soil aggregates, 2) determine the roles of clay translocation and vehicular compac

OBJECTIVES 1993/4 Determine the common species of V AM fungi in the cotton areas of eastern Australia. Place the fungi in pot culture.
