These guidelines have been prepared to meet the objectives shown in the terms of reference. The main task of the guidelines is to provide a framework to improve the quality and appropriateness of program evaluation.

We have conducted a series of experiments at Trangie, Warren, Narrabri and Moree to examine the use of shallow leading tines in conjunction with rippers. Ripper depths of 300, 450 and 600 mm have been investigated.

An experiment was conducted at Narrabri Agricultural Research Station during the 1991-92 season to investigate the response of a range of currently available cotton varieties to irrigation and nitrogen treatments.

The companion project to SOILpak, "Soil management training for advisers to cotton growers" has made a good start in familiarising consultants and agronomists with structural recognition.

During the 1990-91 and 1991-92 seasons planting date experiments were carried out at Narrabri Agricultural Research Station using a range of cotton varieties.
