e0“Grain yields of two semi-dwarf varieties of rice were compared over a range of 0-225 kg applied nitrogen/ha”
e2“Lodging was extensive in both experiments when the tall varieties received high applications of nitrogen, but was absent in the semidwarf varieties at all nitrogen levels”
Title
Yield response of semi-dwarf rice varieties to applied nitrogen in New South Wales
RA Hartley; FL Milthorpe Australian Journal of Experimental Agriculture and Animal Husbandry 1982. doi:10.1071/ea9820402
Other claims from this paper (7)
- Intervention effect Yields of the semi-dwarf varieties increased over the entire nitrogen range.
- Intervention effect Yields of the tall varieties Calrose and Kulu decreased above 100-150 kg nitrogen/ha.
- Intervention effect Lodging was absent in semi-dwarf varieties at all nitrogen levels.
- Association Number of panicles per square metre decreased in the first season with nitrogen.
- Mechanism Harvester inadequacy to recover grain from lodged crops explains lower recovered yields of tall varieties in the second season.
- Mechanism Lodging influenced harvesting much more than grain production.
- Association Semi-dwarf character could increase yields by about 1 t/ha with high nitrogen applications.
