DEVELOPING A TECHNOLOGICALLY ADVANCED SYSTEM FOR GROWING HIGH VALUE VEGETABLE CROPS

J.A. Barnes, B.H. Zischke
Development work at Bundaberg during the past few years has resulted in the widespread adoption throughout Queensland of improved production methods for vegetables. A systems approach with the major components being full-bed polythene mulch, drip irrigation and container grown seedlings for crop establishment is utilised. Drip irrigation allows accurate application of water and soluble fertilizers to the crop. Our aim has been to develop a controlled production system. To do this successfully, simple methods of monitoring soil moisture status and plant nutrient levels are necessary. Both tensiometers and the neutron probe are suitable tools for measuring soil moisture status and scheduling irrigation. Merckoquant Nitrate Test strips and Merckoquant Potassium -Test strips were found to be suitable as field tests for measuring nitrate and potassium concentration in the plant sap. Further studies to evaluate irrigation scheduling and nutrient monitoring and to investigate the effects of various soil moisture and plant nutrient regimes on fruit quality are continuing.
