Metabolisable energy concentration in perennial ryegrass pastures: Multi-site analysis of effects of cultivar, nitrogen fertiliser and white clover content
(New Zealand Grassland Association, 2018-11-13)
To include metabolisable energy (ME) as a nutritive value factor for ryegrasses in the Forage Value Index (FVI) requires data for New Zealand cultivars on the effects of environmental and management ...
Control of gorse (Ulex europaeus) in dryland pasture converted from Pinus radiata forest
(New Zealand Plant Protection Society, 2007-09-24)
The effect of crop sequence, pasture species mixture and nitrogen fertiliser on gorse establishment was monitored over 23 months in land converted from pine forest to a dryland sheep pasture. There were fewer gorse plants in ...
Response of simple grass-white clover and multi-species pastures to gibberellic acid or nitrogen fertiliser in autumn
(NZ Grassland Association, 2013)
Herbage dry matter (DM) production, botanical composition and nutritive value of pastures were measured in response to the application of 24 g/ha gibberellic acid (GA; 60 g ProGibb®/ha) and 50 kg N/ha nitrogen fertiliser ...
The effect of optimum vs deficit irrigation on plant nitrogen uptake and nitrate leaching loss from soil
(Fertilizer and Lime Research Centre, Massey University, 2016)
Nitrate (NO₃⁻) leaching, associated with urine nitrogen (N) deposition during grazing is recognised as a significant environmental problem. In this study it was hypothesised that optimum irrigation could increase plant ...
Whole-farm modelling using different grazing-management strategies with diverse pastures within an irrigated dairy-farm system
(New Zealand Society of Animal Production (Inc), 2018)
The objective of this study was to assess the effect of diverse pasture mixtures and grazing management on profitability of Canterbury dairy farms using a commercial modelling tool, Farmax Dairy Pro. Two years of pasture ...
Integrating plantain (Plantago lanceolata L.) and Italian ryegrass (Lolium multiflorum Lam.) into New Zealand grazing dairy system: The effect on farm productivity, profitability, and nitrogen losses
(MDPI AG, 2021-02)
A two-year farm system study was conducted at Canterbury, New Zealand to evaluate the effects on farm productivity, profitability, and nitrogen (N) losses of integrating plantain (Plantago lanceolate L.) and Italian ryegrass ...
