salinity, and low exchangeable K concentrations are common constraints in many cracking clays. Recommendations for ameliorating sodicity include applying gypsum alone or in combination with deep tillage.

New weed species and resistance problems in 2012 are the ecosystem's response to our substantial changes in agronomy and weed management over the last two decades.

Long-term studies of soil organic carbon dynamics in irrigated cotton -based cropping systems under varying stubble management practices in cracking clays are relatively few.

Cottonspec, a spinning prediction software, has proven a useful management tool, giving spinners immediate feedback on the fibre quality they use. The program gives excellent predictions of yarn quality.

The success of the Australian cotton industry can largely be attributed to science, technology, capacity and innovation.

Australian cotton has global demand and appeal and is considered to be of good quality and reliable in supply.

CBT is the most serious viral disease of cotton in Australia and is transmit-ted by cotton aphids (Aphis gossypii).

Rising diesel and electricity costs are well known to producers. The cost of energy is predicted to rise significantly into the longer term.

Adaptive irrigation control (1) Adaptive control strategies have been developed for real-time management of irrigation. A closedloop or timing (2) actuator hardware to adjust irrigation application

This study aimed to develop new refuge crop options to improve efficacy and provide more choice.

Cotton seed and boll rots are caused by a number of organisms including fungi and bacteria. Recently we isolated the bacterium, Pantoea agglomerans, from rotten bolls.

Since the introduction of transgenic cotton in 1996 a robust resistance management plan (RMP) has been in place which works in consort with an insecticide resistance management strategy (IRMS).

Cotton leaf curl disease (CLCuD) causes serious losses to cotton production in many countries, such as India and Pakistan.

Field experiments stocking varying, densities of H.

Developed by CSIRO, IrriSat is a weather based irrigation scheduling service. It uses satellite imagery to better determine site specific crop coefficients (Kc) that are needed to calculate crop water use.

The 2011 grower survey was done for the Cotton CRC and the Cotton Research & Development Corporation.

This project will improve industry capacity to adopt best management practice and improve water use and energy efficiency, through the provision of training, technical support and extension material.

Some insight to the make up of cotton growing farms can be drawn from the 2011 cotton grower survey.

Irrigators want to improve water use efficiency (WUE) in terms of bales per megalitre with the intention of maximising their profitability or $/ML.
