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 ...
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 ...
Optimum plot shape for variety trials - effect of competition between varieties : Final report 39905083
(1991)
Four plot shapes were compared using four replications of 60 clones. The shapes were 4-row long (4L), 4-row short (4S), 2-row long (2L) and 1-row long (1L). The standard length of 9.2m was used for long plots, short plots ...
An initial evaluation of surge irrigation as a management tool for the Burdekin sugar industry : Final report 89/7
(1991)
Conventional furrow and surge irrigation were compared during the growth of second and third ratoon sugarcane crops on a duplex soil in the Lower Burdekin district. Data collection was severely hampered during this ...
Optimisation of cultural practices for efficient mechanical harvesting : SRDC Final report BS20S
(1991)
Some progress has already been made in identifying field conditions and practices which lead to high dirt levels. These include lodged cane, wet field conditions and cutting with the harvester basecutter below ground ...
