Growing other crops in rotation with cotton appears to offer the best prospect for long term viability of the cotton industry.

The aims of this project, viz: (i) To purchase an item of equipment necessary for the extraction and analyses of allelochemicals present in cotton varieties under evaluation for their rcsi~tance to insect pests (ii) T

This Project was a preliminary study to develop an R&D program into CT based farming systems for the dryland cotton industry.
