Effect of management of previous cereal stubble on nitrogen fertiliser requirement of wheat

MG Mason Australian Journal of Experimental Agriculture 1992. doi:10.1071/ea9920355

Other claims from this paper (19)

Intervention effect Nitrogen fertilizer significantly increased grain yield at Nabawa in all years.
Intervention effect At Wongan Hills nitrogen caused no yield response in 1978 and 1985.
Intervention effect At Wongan Hills nitrogen reduced yield in 1979.
Intervention effect At Wongan Hills nitrogen increased yield in all other years.
Intervention effect At Merredin nitrogen decreased yield in 1984 and 1985.
Intervention effect At Merredin nitrogen increased yield in all other years.
Observation Grain yield responses were small in some years at Wongan Hills and Merredin.
Intervention effect Overall stubble treatment effects were significant only at Nabawa in 1978 and 1985.
Intervention effect Stubble treatment interacted significantly with nitrogen rate at Wongan Hills in 1980 and 1981 and Merredin in 1981, 1983 and 1985.
Intervention effect Nitrogen response was higher with incorporated stubble than burnt stubble.
Intervention effect Optimum economic nitrogen rates tended to be higher with incorporated stubble, with small differences.
Intervention effect Fallow significantly increased overall yield at Merredin in 1979 and 1983.
Intervention effect Fallow interacted significantly with nitrogen rate in all comparison years except 1987.
Intervention effect Non-fallow treatments had greater nitrogen responses.
Intervention effect Stubble incorporation increased soil organic carbon relative to burning.
Intervention effect Fallowing lowered soil organic carbon.
Observation Soil organic carbon declined over time, especially with fallowing.
Observation Soil total nitrogen followed the organic carbon patterns, but less markedly.
Recommendation At 1-3 t/ha residues in continuous wheat in Western Australia's winter rainfall environment, stubble treatment is unlikely to determine nitrogen rate substantially.
