dc.description.abstract The key impact of this project for the Australian cotton industry was via the provision many of the essential knowledge foundations that assisted the rapid transition from a feasibility assessment with commercial partners at the Gilbert River to new cotton industry development at the Gilbert and the Ord Rivers (the later changing from sugar to cotton as the preferred crop). The move to cotton as the base crop for the expanded irrigation area at the Ord River was unexpected when the project started. Tropical registration of Bollgard 3 with sowing windows and resistance management tailored to intra-regional abiotic and biotic risks was supported via expertise that identified all regions with a realistic potential to grow cotton within 10 years, the likely growing season and pest issues for each region and produced a map so distance between regions could be measured. This project also facilitated and supported efficacy studies of Bollgard 3 (VIP3A) on Spodoptera litura a key wet season pest in much of tropical Australia as there was no evidence of prior testing of this species. Following two years of screening it was concluded there would be little chance of survival of Spodoptera litura in the field. A partnership was established to investigate cotton at the Ord River WA in 2017 following a workshop requested by local farmers and Ord expansion proponents on the prospects for growing cotton as a base crop. The workshop coincided with the impending registration of Bollgard 3 technology, the opportunity to develop well-drained levee soils on the west bank of the Ord suitable for wet season planted cotton and a climatic sweet spot analysis (conducted by this project) identifying mid-wet season as the optimal planting time. Securing funding from for the CRC-P project “Developing sustainable cropping systems for cotton, grains and fodder” (an objective of this CRDC project) expanded R&D activities in 2018. Results from research in 2017 & 2018 and test farming of 350 ha in 2018 were very promising with yields > 11 b/ha and above basis fibre quality when planted in the February ‘sweet spot’. Land development has commenced at Carlton Hill in October 2018 and planning for gin construction in late 2020 initiated by the developers. Provided Technical support via soil characterisation and modelling analysis to two properties investigating dryland cotton cropping in the Gilbert Catchment Qld. The most suitable soil characteristics and optimal sowing window to produce reliable yield were identified. The best dryland crops in 2018 were grown on soil types with the characteristics identified in these analysis (well drained, deep uniform loamy-sand texture, minimal surface crusting). This project contributed to DAQ1401 – “Strengthening the Central Highlands Cotton Production System” by climatic analysis, experimental design, data interpretation and analysis to support the August sowing opportunity. Presented at annual field days, review meetings & final report. The industry impacts of this project are now well documented. Provided agronomic, climatic and technical support to many commercial and government agencies. Some will proceed with cotton in 2019 but are now more aware of the potential climatic risks and management challenges and have adjusted plans so a positive gross margin is possible in the worst case scenario (e.g. at Mareeba and the Burdekin). Other enquiries have not progressed due to time required for development or due to reassessment following climatic and resource analysis presented to them. en_US
