Environmental and genetic control of morphogenesis in crops: towards models simulating phenotypic plasticityCSIRO Publishing - Tập 56 Số 11 - Trang 1289 - 2005
Michaël Dingkuhn, Delphine Luquet, Bénédicte Quilot‐Turion, Philippe de Reffye
As molecular biologists are realising the importance of physiology in understanding functional genomics of quantitative traits, and as physiologists are realising the formidable prospects for improving their phenotypic models with information on the underlying gene networks, researchers worldwide are working on linked physiological–genetic models. These efforts are in their early methodo...... hiện toàn bộ
Phosphorus export at the paddock, farm-section, and whole farm scale on an irrigated dairy farm in south-eastern AustraliaCSIRO Publishing - Tập 56 Số 1 - Trang 1 - 2005
Kirsten Barlow, David Nash, Rodger B. Grayson
Phosphorus (P) exported from agricultural land contributes to the eutrophication of inland water systems. Although P export has been extensively researched at the paddock scale, our understanding of farm-scale export is limited. This paper presents the results of a 3-year monitoring project that investigated P export at the paddock, farm-section, and whole farm scales on an irrigated dair...... hiện toàn bộ
Thermal status of sheep at pasture in western New South WalesCSIRO Publishing - Tập 22 Số 5 - Trang 797 - 1971
GD Brown
The thermal status of three unrestrained rams at pasture was studied for a period of 5 days during March in central western New South Wales. A temperature telemetry system was used to measure rectal temperatures, skin surface and subcutaneous temperatures on the mid back, and subcutaneous temperatures of the scrotum of each ram. Rectal temperatures of 40�C and above were recorded for all r...... hiện toàn bộ
The Avon River Basin in 2050: scenario planning in the Western Australian WheatbeltCSIRO Publishing - Tập 56 Số 6 - Trang 563 - 2005
Michael H. O’Connor, Mike McFarlane, James Fisher, Donald G. MacRae, EC Lefroy
Scenario planning was used to identify issues and drivers of change that are relevant to community efforts to improve regional prospects in the Western Australian Wheatbelt. The region, some 20 million hectares in area, is under pressure to respond to a variety of environmental (salinity, erosion, acidification, biodiversity decline), economic (declining agricultural terms of trade), and...... hiện toàn bộ
Changes in organic matter and pH in a podzolic soil as influenced by subterranean clover and superphosphateCSIRO Publishing - Tập 8 Số 2 - Trang 179 - 1957
CH Williams, CM Donald
A further investigation has been made on soils examined by Donald and Williams (1955) in a survey of the influence of superphosphate and subterranean clover (Trifolium subterraneum L.) on podzolic soils formed on granodiorite in the Crookwell district of New South Wales. The soil organic matter was found to have approximately constant proportions of carbon, nitrogen, sulphur, and phosphor...... hiện toàn bộ
Crop responses to lime in long-term pasture-crop rotations in a high rainfall area in south-eastern AustraliaCSIRO Publishing - Tập 52 Số 3 - Trang 329 - 2001
Guangdi Li, K. R. Helyar, Mark Conyers, B. R. Cullis, P. D. Cregan, R. P. Fisher, L. J. C. Castleman, Graeme Poile, C. M. Evans, B. D. Braysher
A long-term trial, known as ‘managing acid soils through efficient
rotations’ (MASTER), commenced in 1992 to develop and demonstrate a
cropping system that is economically viable on the highly acid soils of the
traditional permanent pasture region in south-eastern Australia, so that their
fertility is sustained or improved. There were 2 permanent pasture systems and
2 pasture–crop rotatio...... hiện toàn bộ
Pasture and sheep responses to lime application in a grazing experiment in a high-rainfall area, south-eastern Australia. I. Pasture productionCSIRO Publishing - Tập 57 Số 10 - Trang 1045 - 2006
Guangdi Li, K. R. Helyar, S. J. Welham, Mark Conyers, L. J. C. Castleman, R. P. Fisher, C. M. Evans, B. R. Cullis, P. D. Cregan
‘Managing Acid Soils Through Efficient Rotations (MASTER)’ is a long-term pasture–crop rotation experiment commenced in 1992. One of the objectives was to demonstrate the extent of crop, pasture, and animal responses to lime on a typical acidic soil in the 500–800 mm rainfall zone in south-eastern Australia. Two types of pastures (perennial v. annual pastures) with or without lime applic...... hiện toàn bộ
Reducing rumen methane emissions through elimination of rumen protozoaCSIRO Publishing - Tập 50 Số 8 - Trang 1321 - 1999
R. S. Hegarty
Methanogens living on and within rumen ciliate protozoa may be responsible for
up to 37% of the rumen methane emissions. In the absence of protozoa,
rumen methane emissions are reduced by an average of 13% but this
varies with diet. Decreased methane emissions from the protozoa-free rumen may
be a consequence of: (1) reduced ruminal dry matter
digestion; (2) a decreased methanogen populat...... hiện toàn bộ
