New technology in a developing country - a case study in the Maldives

In 1998, Maafahi Island was leased by the Maldives government to a private company for development as a multi-faceted primary production value-adding project. The project included boat building, agriculture and fish processing. As part of the agriculture project, a hydroponics facility was commenced in 2001, using a novel zero-runoff nutrient system. Virtually no information was available for using this system in tropical conditions; however Deakin University had been undertaking research on the system for tomato production. In 2004, two Deakin scientists visited the island with the specific purpose of assisting the project operators to ‘improve the greenhouse conditions’ and optimise the production from the greenhouse. In essence, the transition to successful production from ‘book learning’ and ‘no practical experience’ was found to be limited by a range of constraints, and demonstrated that a little knowledge is no substitute for a multidisciplinary approach. Progress had come to a standstill, not because of lack of horticultural expertise, but because of lack of understanding of fundamental science, and lack of understanding by equipment suppliers of the requirements imposed by the conditions.

Introduction of new technology into hydroponic tomato growing at the farm level - a case study in collaborative research

In 2000 Deakin University and Elmac Hydroponics, with funding from the Australian Research Council began a collaborative PhD project researching the management and economics for commercial tomato production using the innovative Autopot® hydroponics system. The collaboration between Deakin University, the Elmac farmers and the wider hydroponics industry was central to this research project. A significant outcome was the education of both the researchers and the farmers. Deakin University researchers benefited from the chance to learn about conducting research within the commercial constraints of the industry. Elmac and the wider industry had the opportunity to learn about the methodology, application and limitations of scientific research. However, there are conflicts between the desired educational outcomes for the stakeholders in a collaborative project of this type. In most cases, the award of the PhD degree to the candidate depends entirely on the thesis. A thesis however, would be of little value to most hydroponics farmers. The desired educational outcome for industry is in the application of the results to their situation for improved management of production and increased profit. This paper highlights the benefits and constraints of collaborative research into the introduction of innovative technology to the hydroponics industry.

The viability of commercial tomato production in the Autopot system

An investigation of the viability of commercial tomato production using the Autopot growing system in Australia. The Autopot system is a relatively new hydroponic production system technology that is being introduced onto the market in competition with traditional systems. Although commercial tomato production was found to be significantly more water and nutrient efficient in the Autopot system than in a traditional open system, yields were significantly lower. Financial modelling shows that tomato production in this system would not be commercially viable in Australia for a typical tomato growing venture under current conditions.
