    Development of a large capacity haulout bin : SRDC Final report DDI1S
    (Sugar Research Council, 1990) Harris, HD; Pearce, F
    This report is submitted to the Sugar Research Council as a summary and description of the haulout bin designs which have been generated under project DDI 1 S. Progress with the project has been partly detailed in the Progress Report submitted in October, 1989, the paper on the measurement of hitch loads in haulout bins submitted to the 1990 Conference of the Australian Society of Sugar Cane Technologists, and the paper prepared for presentation to the November 1990 Conference on Agricultural Engineering. Copies of these two papers are attached as Appendix D.

    Selecting clones for better ratooning under wet harvesting conditions : SRDC final report CSR10S
    (1997) Jackson, P; Braunack, M; Foreman, J; Peatey, T; Wood, A
    There were three broad aims of this project: (i) To develop and evaluate a method for screening genetic material under conditions where there is (a) stool damage from harvesting machinery under wet conditions, and (b) waterlogging shortly after harvest. (ii) To evaluate a range of genetic material for ratooning under these conditions, including material generated from previous introgression breeding programs by CSR. (iii) To determine if a breeding program aimed at improving ratooning under wet conditions would be worthwhile, and if so, what sort of methods should be used.

    Improving the yields of ratoon crops of sugarcane : SRDC Final report BS7S
    (SRDC, 1992) Chapman, LS; Ferraris, R; Ludlow, MM; Hurney, AP
    The economics of sugarcane growing improve with the number of ratoon crops which can be grown from a single planting. In Australia, declining yields with increase in the number of ratoons limit a cycle to three to five ratoons, according to district. However, studies by BSES indicate that the most economic strategies involved growing up to six ratoons. If this decline in yield could be reduced, then more ratoons could be obtained from a single planting with the associated economic benefits.

    Improving the efficiency of nitrogen fertilisation of sugarcane under minimum till and trash conservation cultural conditions (Final report SRDC Project BS37S)
    (1992) Chapman, LS; Freney, R; Denmead, OT; Wood, AW; Saffigna, PG
    Objectives of the experiments were (1) Determine the extent of NH3 volatilisation when urea and ammonium sulfate are applied to the surface of a trash blanket in four cane-growing regions. Evaluate the effect of various placements of urea in a trash blanket under wet and dry moisture regimes by quantifying the amount of N recovered in the soil-plant system.

    Methods for accurate identification of canegrubs : SRDC final report BS97S
    (BSES, 1999) Allsopp, PG; Miller, LJ
    The objectives of the project were; determine morphological characters for accurate identifica6tion of larvae and adults of all species of canegrubs; validate the usefulness of morphological characters through DNA analysis; produce written and computer-based keys to enable extension staff and growers to accurately identify larvae and adults of canegrubs.

    Assessment of the potential of sex pheromones as strategic lures for the control of canegrubs : SRDC final report BS17S
    (BSES, 1991) Allsopp, PG; Stickley, BDA
    Sex pheromones were shown to be emitted by females of Antitrogus consanguineus, A. parvulus and L. picticollis. Attraction of males of L. picticollis to females of A. consanguineus shows that the compound or compounds involved are similar in those two species. Detection of pheromones was probably related to the morphology of the adult antennae. One compound was present in emissions of adult female L. negatoria, but this compound could not be identified.

    Evaluating the potential for improved sugar yields by assessing the climatic and soil constraints to production in southern cane-growing districts
    (1999) Muchow, RC; Hughes, RM; Horan, HL
    This project conducted strategic research to better understand the processes of yield accumulation in low temperature NSW environments and to identify limits to yield. The fundamental knowledge gained in this project can be used to assess yield limitations and the scope for yield improvement. In addition, the findings are a pre-requisite to the design of management and genetic improvement strategies to boost production in southern sugarcane growing environments. An additional spin-off of this project is a better functional basis of the processes of yield accumulation encapsulated in the APSIM Sugarcane systems model to allow extrapolation of the findings more broadly across the sugar industry. An analysis framework was used to express sucrose yield in terms of biomass accumulation and the proportion on biomass present as sucrose. Crop biomass was analysed in terms of radiation capture and utilisation. Partitioning was examined in terms of the proportion of crop biomass present as stalk and the stalk sucrose concentration on a dry matter basis. Crops growing under "potential yield" conditions were analysed and compared to those growing under "commercial yield conditions".

    Assessment of aromatic compounds as strategic lures in a canegrub control program : SRDC final report BS34S
    (BSES, 1991) Allsopp, PG
    Anethole, n-butyric acid, citral, citronellal, eucalyptus oil, eugenol, geraniol, hexanoic acid, hexan-1-ol, 3-hexen-1-ol, 1-nonanol, pentanoic acid, phenol, sorbic acid and the standard Trece Japanese beetle floral lure (10:22:11, 2-phenylethylpropionate: eugenol: geraniol) were tested as attractants for Anoplognathus porosus, Antitrogus consanguineus, A. parvulus, Dermolepida albohirtum, Lepidiota crinita, L. negatoria, L. noxia, L. picticollis, and Metanastes vulgivagus. None were effective attractants. The apparent activity of sorbic acid would justify testing butyl sorbate as an attractant.

    Towards functional specifications of a sampling scheme for commercial sampling of prepared cane : final report V89/17
    (BSES, 1990) Robinson, G
    Payment by Australian sugar mills to sugar can growers has for many years been based on samples of "first expressed juice" - the juice squeezed from prepared cane at the number one mill. This basis for payment is perceived by some sugar industry bodies as being less than completely satisfactory. The weaknesses being focussed on in this. report is that it is an inferential method. The amount of pol in first expressed juice is used to estimate the total amount of pol in the cane. This is unsatisfactory because the relationship between pol in first expressed juice and total pol was derived many years ago when there was less pressure exerted at the number one mill. The relationship has not been altered to allow more accurate estimation of total pol.

    Evaluating the leaf chlorophyll meter as a tool for nitrogen management in sugarcane
    (1995) Keating, BA; Smith, K
    Nitrogen is an important constituent of chlorophyll, the compound that gives plants their green colour and the compound that absorbs radiation energy as the basis of plant growth. When nitrogen is in short supply, the chlorophyll content of leaves is reduced and in extreme cases, the leaves take on a yellow (or chlorotic) colour. There is an upper limit to leaf "greenness" and leaf nitrogen can continue to rise even when chlorophyll has reached a "plateau". These simple concepts are illustrated in the figure below. This project was aimed at evaluating a portable leaf chlorophyll meter as a tool in nitrogen management of sugarcane. As chlorophyll is a critical component of the photosynthetic system, reductions in leaf chlorophyll may result in lower sugarcane growth rates and this may impact on final sugar yields. In addition, leaf nitrogen is expensive and time consuming to determine on an extensive basis. The notion was that the chlorophyll meter could provide a far simpler alternative to leaf analysis for the monitoring of nitrogen status of sugarcane crops. The project consisted of measurements of leaf nitrogen and chlorophyll on sugarcane crops grown under a range of nitrogen regimes at locations in the Herbert, Bundaberg and northern NSW regions. Leaves at various levels in the canopy were measured and in the majority of instances samples of the bulk canopy were taken. Samples of the sap from the leaf mid-ribs were collected at the same time and analysed for nitrate using a rapid field test. In all 450 leaf N - chlorophyll meter comparisons were collected at various occasions over the November 1993 to June 1994 period.
