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

This can cover an enormous area because not only does technology intrude into every aspect of growing a crop, by the view of it can change drastically with each different farmer.

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.

I have to tell you now that I will not be presenting such a perspective.

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

Genetic engineering involves the agronomic improvement of crop plants through the introduction of new genetic information (genes) originating from other organisms.

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

Your committee has asked me particularly to focus on the technological needs of the industry. As a background to this it's worth talking briefly about the research councils and their evolution.

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 herbicides are complex molecules and their decomposition often requires several different chemical conversions, each mediated by a variety of organisms.

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.

The fungus Colletotrichum orbiculare(Berk. et Mont.) v. Arx (Walker and Nikandrow, unpublished data) was found causing anthracnose on X.

AZADIRACHTIN is a terpinoid chemical !ound in Meliaceous trees (e.q. White Cedar) but especially concentrated in the seeds of the Neem tree (Azadirachta indica).

As the first presentation on this topic I would like to very briefly outline the major advantages of producing an early crop.

It was once a commonly held belief in central Queensland that, because the potential cotton growing season was a long one, earliness was not an important management consideration.

In recent years the use of agrochemicals, often referred to as pesticides, has become an increasingly controversial topic.

Although resistance to insecticides was a well-documented phenomenon, pest control operators have merely switched from less effective insecticides to newer more potent compounds and thereby kept ahead of the resistanc

To the question "Can nutrition affect earliness?" the answer must be a definite Wes". Further, it will be just as important a factor as irrigation or pest management.

One of the important characteristics elevating Heliothis spp. to major pest status is the ability to enter facultative diapause.
