This article reviews research coordinated by the Australian Cotton Cooperative Research Centre (CRC) that investigated production issues for irrigated cotton at five targeted sites in tropical northern Australia, north of 21°S from Broome in Western Australia to the Burdekin in Queensland. The biotic and abiotic issues for cotton production were investigated with the aim of defining the potential limitations and, where appropriate, building a sustainable technical foundation for a future industry if it were to follow. Key lessons from the Cotton CRC research effort were: (1) limitations thought to be associated with cotton production in northern Australia can be overcome by developing a deep understanding of biotic and environmental constraints, then tailoring and validating production practices; and (2) transplanting of southern farming practices without consideration of local pest, soil and climatic factors is unlikely to succeed. Two grower guides were published which synthesised the research for new growers into a rational blueprint for sustainable cotton production in each region. In addition to crop production and environmental impact issues, the project identified the following as key elements needed to establish new cropping regions in tropical Australia: rigorous quantification of suitable land and sustainable water yields; support from governments; a long-term funding model for locally based research; the inclusion of traditional owners; and development of human capacity.

For nearly two decades (1994–2012) a series of three consecutive Cooperative Research Centres (CRC) dealing with cotton production provided the impetus and financial support for a substantial body of soil science research in eastern and northern Australia. Focusing on the most commonly utilised soil for irrigated crop production, the Vertosol, CRC-affiliated soil researchers undertook detailed soil inventories of cotton-growing valleys in New South Wales, and tackled a range of applied soil research questions that faced the entire Australian cotton industry. Across the broad categories of soil mapping and characterisation, soil physical condition, salinity and sodicity, soil chemical fertility, and soil carbon and biota, some 120 CRC-affiliated research papers were published in peer-reviewed journals during the years of the CRC. Findings from this body of research were fed back to the industry through conferences, extension workshops and materials, and to a lesser extent, the peer-reviewed publications. In certain cases, underpinning basic research was carried out concurrently with the more applied research, meaning that the cotton CRC were effectively supporting advances in the discipline of soil science, as well as in sustainable cotton production. A feature of the soil research portfolio over the span of the three cotton CRC was that priorities shifted according to the interplay of three factors; the natural maturation of research topics and the concomitant evolution of cotton farming systems, the rising importance of environmental implications of agricultural land use, and the emergence of carbon as a national research priority. Furthermore, the commitment of the CRC to education resulted in the involvement of undergraduate and postgraduate university students in all aspects of the soil research effort. A legacy of the triumvirate of cotton CRC is a wide-ranging body of both applied and basic knowledge regarding the physical, chemical and biological attributes of Australian Vertosols used for irrigated agriculture.

Markets for Australian beef throughout the 20th century have been moulded by world wars, economic depressions, droughts, transport technology, cattle breeding, trade barriers, global competition, livestock disease eradication, human health risks, food safety, Australian Government policy, consumerism and beef quality. Major ‘shocks’ to beef marketing include the development of successful shipments of chilled carcases to Britain in the 1930s, the widespread trade disruption caused by World War II, expansion (early 1950s) and then a reduction in beef exports to Britain (1956), the introduction and then proliferation of Bos indicus derived cattle in northern Australia (1960s), licensing and upgrading of Australian abattoirs to export to USA and the consequential brucellosis and tuberculosis eradication campaign leading to record export tonnages of Australian processing beef to USA (1960–70). In 1980, increased beef trade to Japan began, leading in the late 1980s to expansion of high-quality grain finished products into that market. By 1993, beef exports to Japan (280.5 kt) exceeded those to USA (274.4 kt), signalling the significant shift in beef exports to Asia. Commencing in about 1986, the USA recognised the value of beef exports to Asian markets pioneered by Australia. Australia’s share of the Japanese and South Korean markets has been under intense competition since that time. Another major influence on Australia’s beef market in the early 1990s was growth in live cattle exports to Asian markets in Indonesia, Malaysia and the Philippines. Live exports accounted for 152000 heads in 1992 and 858000 heads in 1996. Improved management systems (e.g. fences) and consequent regulation of cattle supply even in the wet season, a by-product of the brucellosis and tuberculosis eradication campaign, were indirect drivers of the growth in live exports. Throughout the period 1940–2000, domestic consumption of beef and veal declined from 68 to 33.3 kg/head.year, reflecting competition from other foods, perceptions of health risks, price of beef, periodic food safety scares, vegetarianism, changes in lifestyle and eating habits and lack of consistency of eating quality of beef. Despite this decline, the domestic Australian beef market still consumes a significant component (37%) of total Australian beef production. In 1984–85, the reform of the Australian Meat and Livestock Corporation set in train a major directional change (‘New Direction’) of the beef sector in response to beef market trends. Under Dick Austen’s leadership, the Australian Meat and Livestock Corporation changed the industry’s culture from being ‘production-driven’ to being ‘consumer-driven’. Market research began in Australia, Japan and Korea to establish consumer preferences and attitudes to price, beef appearance and eating quality. Definite consumer requirements were identified under headings of consistency and reliability. The AusMeat carcass descriptors were introduced and a decade later traits like tenderness, meat colour, fat colour, meat texture, taste, smell, and muscle size were addressed. These historical ‘shocks’ that shaped the Australian beef markets have all been accompanied by modification to production systems, breeding programs, herd structure, processing procedures, advertising and promotion, meat retailing and end-use. The increasing importance of the food service sector and the ‘Asian merge’ influence on beef cuts usage in restaurant meals and take-away products are the most recognisable changes in the Australian food landscape. The Cooperative Research Centre¿s research portfolio was built around the changing forces influencing beef markets in the early 1990s. Australia needed to better understand the genetic and non-genetic factors affecting beef quality. One example was the poor success rate of cattle being grain-fed for the Japanese premium markets. Another was the relative contribution of pre- and post-slaughter factors to ultimate eating quality of beef. The Meat Standards Australia scheme was launched in 1997 to address this problem in more detail. The Cooperative Research Centre contributed significantly to this initiative. In the year 2001, Australia, with only 2.5% of world cattle numbers retains the position of world number one beef trader. We trade to 110 countries worldwide. The Australian beef sector is worth A$6 billion annually. The diversity of Australian environments, cattle genotypes and production systems provides us with the ability to meet diverse specifications for beef products. A new set of market forces is now emerging. Strict accreditation rules apply to Australian producers seeking access to the lucrative European Union market. Transmissible spongiform encephalopathies like bovine spongiform encephalopathy and scrapie are a continuing food safety concern in Europe. This and the foot and mouth disease outbreak in Britain early in 2001 have potentially significant indirect effects on markets for Australian beef. And the sleeping giant, foot and mouth disease-free status of Latin American countries Brazil, Uruguay and Argentina continues to emerge as a major threat to Australian beef markets in Canada and Taiwan. As in the past, science and technology will play a significant role in Australia¿s response to these market forces.

Enhancing nutrient use efficiency (NUE) with minimal threat to environment has become critical for our agriculture food production systems (FPS) to sustain the burgeoning population. Nanotechnology with nanoscale inputs for production of nano agri-inputs (NAIPs) has emerged as an innovative solution for addressing issue of low or declining nutrient use efficiency (NUE) with minimal environment footprint. Nanotechnology is a promising field of research which has the potential to offer sustainable solutions to ever pressing challenges confronting our modern intensive agriculture. Nanotechnology employs nanomaterials which typically have small size (1–100 nm) which imparts unique characteristics and benefits. In addition to numerous other benefits, large surface area to volume ratio offers opportunity for better and effective interaction of nanoparticles to target sites. Nano-fertilizers hold potential to fulfil plant nutrition requirements along with imparting sustainability to crop production systems and that too without compromising the crops yield. Indian Farmers Fertilizer Cooperative Limited (IFFCO) - the farmers’ own fertilizer cooperative has been in the forefront for promotion of agro-technologies and novel agri-inputs to mitigate problems faced by the farmers. It has indigenously innovated at its Nano Biotechnology Research Centre (NBRC) at Kalol, Gujarat and succeeded in R& D and manufacturing of proprietary nano-fertilizers viz. nano urea, nano zinc, and nano copper. These nano-fertilizers utilize the dynamics of shape, size, surface area and bio-assimilation. There efficacy was evaluated on the basis of multi-location multi-crop trials under varying crop seasons, both by the research institutes and also on the progressive farmers’ fields across 11,000 locations on 94 crops across India. Independently, nano nitrogen, nano zinc, and nano copper have also been tested for bio-efficacy- bio safety- toxicity and environment suitability. IFFCO nano-fertilizers meet alll the current national and international guidelines related to nano technology or nano scale agri-inputs.They are in sync with OECD testing guidelines (TGs) and “Guidelines for Testing of NAIPs and Food Products” released by the Department of Biotechnology, Government of India. Harvested produce of crops applied with IFFCO nano-Urea, nano-zinc, and nano-copper have been found fit for consumption with no adverse effect. This paper reviews the benefits of nanofertilizers (Nano N, Nano Zn and Nano Cu) towards increasing nutrient use efficiency and crop productivity and produce quality in general and the journey of IFFCO nano-fertilizers (IFFCO’s Nano Urea, Nano Zn and Nano Cu) from conception to PILOT to PLANT stage has also been covered in this paper.

There is growing interest in magnesium alloys as structural materials for the automotive, aerospace and electronic industries. However, the corrosion performance of most magnesium alloys is not good enough for the increasingly diverse practical applications. The Cooperative Research Centre for Cast Metals Manufacturing (CAST) is an Australian research organisation established to cope with the problems associated with development and application of light metals. Corrosion and prevention of magnesium and its alloys has been an important part of CAST’s research program since 1995. The research effort in this area is focused on solving corrosion problems relative to the application of magnesium alloys in the automotive industries. Nevertheless, encompassed by the requirements of the applied research, some fundamental studies have also been conducted. This paper presents a brief summary of some of the research achievements in this area recently made by CAST. They include studies of corrosion behaviour, alloying effects, corrosion inhibition and surface treatment of magnesium alloys.

Increasing the proportion of the landscape planted to deep-rooted perennial pasture species is recognised as one of several remedial actions required for the control of dryland salinity in southern Australia. The widespread use of perennials in farming systems is limited at present by the lack of well-adapted perennials that can be grown to reduce recharge in a landscape where drought, soil acidity, temporary waterlogging, infertile soils and unrestricted grazing prohibit the use of many species. The range of plants adapted to salinity also needs to be expanded to stabilise and ameliorate soils already degraded by rising watertables and to increase the profitability of grazing discharge regions within the landscape. This paper describes the steps involved in a national forage screening and breeding program initiated by the Cooperative Research Centre (CRC) for Plant-based Management of Dryland Salinity1, seeking to expand the range of perennial and or salt-tolerant forage plants that can be incorporated into farming systems of southern Australia. It describes the target environments, soil constraints, farming systems and the criteria being considered when assessing the potential of new plants, including assessment of the weed risk posed by introducing new species. This paper forms an introduction to a special issue which presents the outcomes of the pasture species field evaluation and plant breeding program conducted by the CRC.

Research into the genetics of whole herd profitability has been a focus of the Beef Cooperative Research Centre for Beef Genetic Technologies over the past decade and it has been identified that measures of male reproduction may offer a potential indirect means of selecting for improved female reproduction. This paper describes the experimental design and provides a descriptive analysis of an array of male traits in Brahman and Tropical Composite genotypes managed under the medium to high stress, semi-extensive to extensive production systems of northern Australia. A total of 1639 Brahman and 2424 Tropical Composite bulls with known pedigrees, bred and raised in northern Australia, were evaluated for a comprehensive range of productive and reproductive traits. These included blood hormonal traits (luteinising hormone, inhibin and insulin-like growth factor-I); growth and carcass traits (liveweight, body condition score, ultrasound scanned 12–13th rib fat, rump P8 fat, eye muscle area and hip height); adaptation traits (flight time and rectal temperature); and a bull breeding soundness evaluation (leg and hoof conformation, sheath score, length of everted prepuce, penile anatomy, scrotal circumference, semen mass activity, sperm motility and sperm morphology). Large phenotypic variation was evident for most traits, with complete overlap between genotypes, indicating that there is likely to be a significant opportunity to improve bull fertility traits through management and bull selection.

Recognizing the growing interest in the application of organic photovoltaics (OPVs) with greenhouse crop production systems, in this study we used flexible, roll-to-roll printed, semi-transparent OPV arrays as a roof shade for a greenhouse hydroponic tomato production system during a spring and summer production season in the arid southwestern U.S. The wavelength-selective OPV arrays were installed in a contiguous area on a section of the greenhouse roof, decreasing the transmittance of all solar radiation wavelengths and photosynthetically active radiation (PAR) wavelengths (400–700 nm) to the OPV-shaded area by approximately 40% and 37%, respectively. Microclimate conditions and tomato crop growth and yield parameters were measured in both the OPV-shaded (‘OPV’) and non-OPV-shaded (‘Control’) sections of the greenhouse. The OPV shade stabilized the canopy temperature during midday periods with the highest solar radiation intensities, performing the function of a conventional shading method. Although delayed fruit development and ripening in the OPV section resulted in lower total yields compared to the Control section (24.6 kg m−2 and 27.7 kg m−2, respectively), after the fourth (of 10 total) harvests, the average weekly yield, fruit number, and fruit mass were not significantly different between the treatment (OPV-shaded) and control group. Light use efficiency (LUE), defined as the ratio of total fruit yield to accumulated PAR received by the plant canopy, was nearly twice as high as the Control section, with 21.4 g of fruit per mole of PAR for plants in the OPV-covered section compared to 10.1 g in the Control section. Overall, this study demonstrated that the use of semi-transparent OPVs as a seasonal shade element for greenhouse production in a high-light region is feasible. However, a higher transmission of PAR and greater OPV device efficiency and durability could make OPV shades more economically viable, providing a desirable solution for co-located greenhouse crop production and renewable energy generation in hot and high-light intensity regions.
