Using mulch to improve water use efficiency of in-ground native flowers

Monitoring of soil moisture fluctuations under mulched and un-mulched native flowers will provide valuable information in assessing the crop water use and potential water savings associated with adoption of this practise. This information would be valuable in encouraging growers to adopt best management practises for sustainable flower production.

Investigating use of irradiation for disinfestation on Custard Apples

The ability to access new international markets particularly New Zealand is the focus of this project for the custard apple industry. Custard apple require a fruit fly disinfestation treatment to access New Zealand markets. Irradiation has shown to be an effective treatment in other fruits and has the potential to be introduced in a relatively short time frame. The project will assess the effect of irradiation on the quality and storage life of custard apples simulating an international supply chain.

Using bacteria in banana for efficient use of fertilizer

This project aims to develop sustainable banana production practices by improving efficiency of fertilizer use. We will investigate how we can reintroduce endophytic beneficial bacteria that can be established inside the banana host to provide lasting and durable benefits to growth. In the current research we have been able to isolate bacteria from inside banana and preliminary characterisation indicates isolates with a range of attributes for improved efficiency of fertilizer uptake. Experimentation will include evaluation in vitro and pot trials and field trials using bacteria most likely to increase plant access to nutrients as well to compare nutrient impacts from conventional verses slow release fertilizer.

Combined Use of Solid of Revolution, Thin Shell, and Interphase Elements for Analysis of Cylindrical Shells

Near the boundaries of shells, thin shell theories cannot always provide a satisfactory description of the kinematic situation. This imposes severe limitations on simulating the boundary conditions in theoretical shell models. Here an attempt is made to overcome the above limitation. Three-dimensional theory of elasticity is used near boundaries, while thin shell theory covers the major part of the shell away from the boundaries. Both regions are connected by means of an “interphase element.” This method is used to study typical static stress and natural vibration problems

Phosphonate use for Phytophthora root rot management in Shepard

Phytophthora root rot of avocados and is the major limiting factor to avocado production in Australia. The disease has a significant impact on productivity. An integrated program is recommended for Phytophthora root rot management with phosphorus acid a key component of this strategy. Monthly root analyses will be conducted on 5 avocado orchards across a range of growing environments on the Atherton Tablelands. Detailed tree phenology data will be collected orchard at the same time the root sampling occurs. In conjunction with the phenological data, decay curves will allow the development of recommendations to optimize phosphorous acid applications for the management of Phytophthora root rot in Shepard avocados.

Rural Water Use Efficiency 4

The purpose of this proposal is to detail the proposed service provision project to be undertaken by staff from the Department of Employment, Economic Development and Innovation (DEEDI – formerly DPI&F) to the Flower Association of Queensland Inc (FAQI). FAQI to successfully fulfil FAQI’s requirements under the Rural Water Use Efficiency 4 project.

GRDC Improving crop and farm water use efficiency in Australia

Project Objectives: 1. Improving yield and water use efficiency of the wheat crop, the backbone of the Australia grains industry, by better matching management, variety, soil and climate. The aim is thus increasing kg grain/ha per mm evapotranspiration and kg grain/ha per mm rain. 2. Improving land and water productivity and profit by better arrangement of the components of the cropping system. This involves better allocation of farm resources (land, water, machinery, labour) and identifying strategies that account for trade-offs between profit and risk. The aim is thus improving $/ha per year and mm rain in a risk framework.
