This paper discusses recent progress with the refinement of promising methods, both direct and indirect, for measuring the severity of compaction in cracking clays used for irrigated cotton.

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.

Macquarie Agribusiness report on the market for Australian raw cotton includes an overview of the Australian and world cotton industry.

A three year investigation is being undertaken at Massey University to study the effect of condensed tannins, heat and solvent extraction upon the nutritive value of cottonseed meal for ruminant and monogastric farm a

During the 1991-92 season, a 1 ha block of unsprayed raingrown cotton near Dalby was sampled for parasite activity in heliothis larvae.

As more than 94% of the Australian crop is exported, the world situation has greater bearing on the outlook for the Australian grower than most of his competitive counterparts who have the benefit of their own large d

Recent research has indicated that two species of native egg parasitoids, Trichogramma (Trichogrammanza) carverae Oatman and Pinto and Trichogrammatoidea bactrae Nagaraja, have potential as biological control agents o

I have been asked to address three major points: I . Why is risk management important? 2. Does a grower nee-d to know all the details of a market before he can become involved with risk management? 3.

This paper presents techniques used for rearing egg parasitoids on AGM eggs in an experimental facility at the QDPI Division of Plant Protection entomology laboratories in Toowoomba.

This paper provides an overview of the Cotton Research and Development Corporation project DDI lL, which is in its final year at the University of Southern Queensland.

There are, few parasitoids which specifically attack the pupal stage. This is perhaps understandable since pupae are not readily accessible, being in the soil.

The question is asked - Why grow Pima in A ustraha? There are different answers. The most obvious is the economic consideration, then there is the challenge of doing something new and different.

Retained hills are now a well-established management strategy in the Australian Cotton Industry.

In surface irrigation systems we use beds rather than growing thee crop on the flat for several reasons.

Obviously, avoiding trafficking wet soil is one means of avoiding soil structural damage. Another is to use a vehicle with lower ground pressure, by using dual tyres, wide tracks, etc.

The importance of Heliothis has grown with the advent of resistance in H.armigera to various pesticides.

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.
