Evaluation of biostil dunder and mixtures with nitrogen fertilisers for sugarcane nutrition
(1990)The aims of this project were: (a) to measure the cane and sugar yield responses from the application of biostil dunder on its own and in mixtures with nitrogen fertilisers in field trials; and (b) to assess the suitability ... -
Soil constraints to productivity improvement
(1990)Yields of most crops are known to decrease if that crop is grown continuously without fallowing or rotation with other crop species. Sugarcane has been grown continuously on many fields in Queensland for 50-100 years. ... -
The effect of soil physical properties on growth and yield of sugarcane
(1991)The literature reporting the effect of soil physical properties on sugarcane growth and yield has been reviewed and areas for further investigation are suggested. There is conflicting evidence in relation to the number ... -
Enhancement potential of 'Ethokem' in control of the common reed (Phragmites australis) using glyphosate
(BSES, 1991)A significant, positive response trend to the addition of the adjuvant Ethokem to Roundup has demonstrated the potential for this additive to enhance herbicidal activity when applied to control the common reed, Phragmites ... -
Soil constraints to productivity improvement
(1991)Evidence from investigations into fumigation, fungicide application, fallowing and growth of sugarcane on recently cultivated soils strongly suggests that yields in established cane growing areas are being restricted by ... -
Improving water penetration in the Burdekin
(1990)Poor water penetration represents the greatest source of preventable yield loss in the Burdekin district. The problem occurs in all four mill areas in the district with about 18 000 ha affected to some degree. Cane yield ... -
Viability of the seed of itch grass (Rottboellia cochinchinensis) in the Burdekin district
(BSES, 1990)Itch grass, raoul grass, or guinea fowl grass emerged as a problem weed of sugarcane fields in the Burdekin district of North Queensland during the late 1970s - early 1980s. It is considered to be a native of tropical ... -
The effect of zinc deficiency as a factor limiting sugarcane growth (SRC Project BS14S - Final Report)
(1990)Results from this project confirm that substantial yield responses to zinc application can be expected in deficient soils in North Queensland. Deficiency is commonly associated with lime application. Three soil and two ... -
Phytotoxic substances associated with the decomposition of sugarcane trash residues. (Final report SRDC Project BS31S)
(1992)Ratooning through trash blankets is generally effective with minor exceptions for certain varieties and in cold or waterlogged soils. Information was required to determine whether these effects are normal reactions of slow ... -
Assessment of various food constituents as feeding attractants for canegrubs in a pest control program : SRDC final report BS35S
(BSES, 1991)Cellulose acetate filter disks were used to evaluate sugars, amino acids and ascorbic acid as feeding stimulants for canegrubs. Fourteen sugars, 18 amino acids and ascorbic acid were tested with third instars of Antitrogus ... -
The production and evaluation of gene probes for diagnosis of sugarcane mosaic virus and Fiji disease virus (Final report SRDC Project BS10S)
(BSES, 1991)Specific and sensitive cDNA probes have been developed for detection of both FDV and SCMV in diseased sugarcane plants. Results from glasshouse evaluation indicate that FDV probes are not sensitive enough to be used for ... -
Population dynamics of Inopus rubriceps in sugarcane fields with emphasis on bionomic factors assisting pest management (Final report SRDC Project BS11S)
(BSES, 1991)Restrictions were placed on the use of dieldrin in 1987 and its registration for use in the sugar industry lapsed in mid-1991. As no other insecticide is presently available to replace dieldrin, there is an urgent need ... -
Pachymetra chaunorhiza as a factor involved in stool tipping in North Queensland : SRDC final report BS33S
(BSES, 1991)The objectives of this project were to determine the soil and environmental factors favouring Pachymetra root rot, and how these contributed to stool tipping in the moderately resistant and susceptible varieties Q117 and Q124. -
Selection of superior crosses of sugarcane : SRDC final report BS6S
(1991)The impact of GxE interaction on the response to three methods of selection was assessed over three locations and three crop-years. The three selection methods considered were two previously used procedures, mass (individual) ... -
Regeneration of sugarcane plants from protoplasts
(1991)This study aimed to develop a protoplast regeneration system for sugarcane so that gene transfer techniques could be applied for cultivar improvement. Published techniques for embryogenic callus culture, cell suspension ... -
The effect of sugarcane rust (Puccinia melanocephala) on yield
(BSES, 1985)This report details the results obtained from two trials to assess yeild loss caused by sugarcane rust and also outlines the epiphytotiology of the rust disease. -
Stool eradication using minimum tillage or glyphosate and associated planting methods
(1985)Research designed to establish practical techniques for stool destruction at the end of a crop's cycle is described. Trials conducted at the Tully Sugar Experiment Station during 1982 and 1983 have shown that glyphosate ... -
The evaluation of rope-wick application of glyphosate as a method of chemical weed control in some typical farm locations
(BSES, 1984)The effectiveness of rope-wick application of glyphosate (as Roundup) in controlling the common reed Phragmites australis in the Moreton and Rocky Point areas has fostered interest in this method of chemical weed control ... -
The inheritance of ash in juice from sugar cane
(1983)Ash per cent juice data were obtained for varieties within 97 crosses in original seedlings in 1979 and for varieties within 86 crosses from three factorial polycrosses in 1981, on the Bundaberg Sugar Experiment Station. ...
