Availability of phosphate fertilizers in unlimed and limed acid soils as affected by wetting and air-drying
(Lincoln University, 1991)
The interactions between air-drying and rewetting, and liming or timing of phosphate (P) fertilizer application on plant availability of monocalcium phosphate (MCP) or reactive phosphate rock (PR) fertilizers were studied ...
Assessment of wheat x maize doubled haploid technology for genetic improvement of New Zealand wheat
(Lincoln University, 1999)
New Zealand must continue to produce superior wheat cultivars to retain competitive advantage within New Zealand and contribute in terms of global wheat breeding. Doubled haploid (DH) technology allows the production of ...
Effects of different crop residues and management practices on soil nitrogen dynamics, yield and recovery of nitrogen by wheat
(Lincoln University, 1998)
In a large field experiment on an irrigated Templeton silt loam (Udic Ustochrept) soil using a completely randomised block design with six replicates (each main plot = 30 x 20m), main plot treatments of wheat and ryegrass ...
Response of wheat cultivars to chlorsulfuron and the effect of nitrogen availability
(Lincoln University, 1993)
Sensitivity of wheat cultivars to the herbicide chlorsulfuron was tested and mechanisms to explain their differential response determined. In addition, a sensitive wheat cultivar, Rongotea, was selected and the effect of ...
