The effect of amidochlor and mefluidide on the development of perennial ryegrass (Lolium perenne)
(Lincoln College, University of Canterbury, 1988)
A field trial was set up in spring 1986 to study the effects of the two plant growth retardants amidochlor (N-(acetoamino)methyl-2-chloro-N-(2,6-diethylphenyl) and mefluidide (N(2,4-dimethyl-5-[[(trifluoromethyl) sulphonyl] ...
The Proceedings of the Lincoln College Farmers' Conference 1969
(Lincoln College (Lincoln, N.Z.)., 1969)
The Lincoln College Farmers’ Conference was an annual event held over a period of thirty six years from 1951 to 1986. It was a forum for farmers with participation in the early years by district nomination. The strength ...
Active light sensing of canopies in crop management: Pastures and arable crops
(Fertilizer and Lime Research Centre, 2015-02)
A field spectrometer with an active light source was tested as a potential canopy sensor for dairy pastures (‘TEC-5’, YARA). To study the applicability of the sensor on pasture for the intensive radiation conditions of NZ ...
Optical sensors for variable rate nitrogen application in dairy pastures
(New Zealand Grassland Association, 2017)
Reducing the amount of nitrogen (N) fertiliser applied to dairy pastures down to agronomically optimised levels would have positive economic and environmental results. The ability of commercially available optical sensors ...
Nutrient recycling using biowastes from diverse sources
(Lincoln University, 2018)
Phosphorus is a limiting nutrient in crop growth and thus widely used as an agricultural fertiliser. It cannot be substituted by another element, nor newly synthesized. Hence, global food production is ultimately dependent ...
Management zone delineation in arable crop systems
(Fertilizer and Lime Research Centre, 2015)
Management Zone Delineation (MZD) could be of increasing importance for its economic and environmental benefits through varying rates of crop inputs to meet site-specific demands across individual ...
Fertilizer and stocking rates on two King Country soils
(New Zealand Grassland Association., 1973)
Parent materials such as volcanic ash and sedimentary siltstone
and sandstone form soils which differ markedly in their physical
and chemical properties. In stocking x fertilizer rate trials on
two families of soils, ...
Assessing biomass yield of kale (Brassica oleracea var. acephala L.) fields using multi-spectral aerial photography
(Fertilizer and Lime Research Centre, 2015-02)
Aerial images were taken in June 2014 with a multispectral VIS/NIR camera of the canopy from 14 kale (Brassica oleracea var. acephala L.) fields in Canterbury, New Zealand before this forage was grazed by cows. Images ...
Potential pasture nitrogen concentrations and uptake from autumn or spring applied cow urine and DCD under field conditions
(MDPI, 2016-06)
Nitrogen (N) cycling and losses in grazed grassland are strongly driven by urine N deposition by grazing ruminants. The objective of this study was to quantify pasture N concentrations, yield and N uptake following autumn ...
Plantain silage quality under variable management practices
(New Zealand Grassland Association, 2018-11-17)
Two studies investigated the effect of regrowth and additives on preservation and quality of plantain ensiled in spring using a micro-silage technique. Study 1 compared the effect of regrowth at four (4L), five (5L) or six ...
