Technical Annual Report 2000/01 113 Future Activities: The demonstration plot at the Melon Patch and TPFM has become a focal point for vegetable growers to look at the best practice systems and should be used in the future to demonstrate green manure crops and other aspects of sustainable vegetable growing systems in the Top End. It is a neutral place where growers feel comfortable to attend workshops, which will include any future demonstration crops and provides a constant reminder for improvements that can be made without the growers having to deviate from their current routines. Acknowledgements: We would like to thank Lien Truong for provision of the seed of the local bitter melon selection, Laurence Ah Toy of the Melon Patch, Koolpinyah Station, for provision of the land and services and Bill Gilbert of Territory Produce Freight Management for his support and constant liaison with growers. PROJECT: Vegetable Management Trial 2000 Project Officers: M. Darcey, M. Gosbee, M. Traynor, E. Maroulis and P. Hopkinson Location: CPHRF Objective: To demonstrate the yield and quality advantages of the DPIF vegetable 'package' which includes plastic mulch, 'T' tape, cover crops, hybrid varieties and fertigation. To improve the adoption of more sustainable and profitable vegetable production techniques through quantifiable treatment effects. Background: DPIF has invested significant resources in developing a management package to produce vegetables in the Darwin region. The package includes the use of a cover crop in rotation with the vegetable crop, the use of plastic mulch and T tape into which the crop is sown and the use of hybrid vegetable varieties, which are expected to produce greater yields. Due to a change in growers entering the industry and a significant shift in commodities grown the package has not been widely adopted. DPIF has conducted regular demonstration plots on growers' properties but little emphasis has been placed on the profitability of adopting the package or new technology. Method: Treatments Plus and minus plastic mulch with T tape Open pollinated (OP) versus hybrid okra variety Both treatments were repeated in cover crop and non-cover crop situations. Therefore: 1. Traditional No plastic mulch and drip irrigation Variety -open pollinated local selection (Clemsons Spineless) 2. Traditional H No plastic mulch and drip irrigation Variety selected hybrid (Spring Pearl) 3. Package Plastic mulch and T tape irrigation Variety -open pollinated local selection (Clemsons Spineless)
