Proper nutrition is one of the many factors necessary in achieving the high yield and quality standards we have set for our cotton crop.

Determination of the petiole nitrate nitrogen concentration (PNN) in the youngest fully expanded leaf (YFEL) of cotton is a useful indicator of plant nitrogen status.

Having outlined the complexity of this topic, I now intend to summarise the soil and plant mineral relations during waterlogging, followed by a brief review of the scientific principles to improve understanding of the

Well to satisfy everyones's curiosity, r will answer the question straight away. Yes, we can survive resistance! However, in answering it, I shall put another, perhaps even more thought provoking than the first.

In addressing this topic I have been asked to consider the development of management strategies for farmers faced with a shortage of irrigation water, a situation that appears endemic in the Gwydir Valley.

As major pests of cotton production, Heliothis spp. are of most concern to growers during the summer when they are active and damaging crops. Once autumn arrives and the crop is picked, Heliothis are soon forgotten.

The Cotton Council has been funding our project, for which we intend to identify cotton varieties with efficiency of dry matter production when irrigation is expensive, or relatively inexpensive.

Ripping (deep soil working ) can give conflicting responses. Sometimes it i ncreases cotton yields and other times it de creases cotton yields.

The two-spotted spider mite, Tetranychus urticae, ranks second to Heliothis in importance as a pest of cotton. Mites reduce profitability by reducing the yield and fibre quality of cotton.

Yield responses to increasing amounts of irrigation water have been demonstrated in the past by individual trials. In these trials watering occured at varying deficits of soil moisture below field capacity .

I will admit, nonetheless, that there are opportunities to be grasped on occasions such as this, since one can use them (whether they be publicly documented or not) to say things that wquld be inappropriate in one&#03

As most of you are aware, the Siratac Cotton Management Advisor computer program is being rewritten. There will be those amongst you who are unaware as to why this is being done.

Australian Cotton Conference. I have been asked to speak to you on the effects on the industry of the US Farm Bill and other political moves.

Most, if not all, entomologists involved in the development of cotton insect management systems agree that an essent1al part of a successful Integrated Pest Management (IPM) program is the ava;lability of an eff1cac1o

Irrigation scheduling in cotton using the water balance program WATERSCHED has been the subject of an extension development project in Queensland for two years. The project is funded by Cotton Research Council.

The Australian Bureau of Agricultural and Resource Economics is one of the few organisations that publish cotton pri ce forecasts t o assist growers in making their planting decisions.

Insecticides can poison insects in many ways. Insecticides r...:an interfere with metabolic processes , of energy production, cuticular growth and hormone production.

Irrigation trials have been conducted at Byee over the last two seasons as part of a Statewide project funded by the Cotton Research Council.
