“…The rates of N applied in this study are not recommended for commercial use. It is important to identify a legume which can survive and persist in a mixture with cocksfoot to alleviate the main yield constraint of N deficiency and the associated reduction in pasture quality (Lee and Cho 1985;Moloney 1991;Edwards et al 1993).…”

“…However, the impact can be quantified in relation to thermal time and responses predicted. The aggressive growth habit of cocksfoot, compared with legumes such as white clover (Trifolium repens), leads to a decrease in the clover component (Lee and Cho 1985;Moloney 1991 (Peri et al 2002b) and decreased pasture grazing preference (Edwards et al 1993).…”

The effects of temperature, water and nitrogen on pasture production of an 8 year old 'Wana' cocksfoot pasture were quantified at Lincoln University, Canterbury. The maximum dry matter (DM) yield was 22.0 t/ha/yr when neither water nor N were limiting. Crude protein yield of +N pastures was 3.2-4.2 t/ha/yr compared with 1.0 t/ha in -N pastures. Metabolisable energy averaged 178*103 MJ ME/ha/yr for the +N pastures compared with 69*103 MJ ME/ha/yr for -N pastures. Seasonal differences in pasture production were explained in relation to thermal time with 7.0 kg DM/oCd for N fertilised pastures and 3.3 kg DM/oCd when no N was applied. During periods of water stress, relative yield decreased at a rate of 1.4%/mm when the soils critical limiting deficit of 78 mm was exceeded. Keywords: Dactylis glomerata, irrigation, nitrogen, thermal time.

“…Several authors have linked dry matter (DM) production of cocksfoot ( Dactylis glomerata L.) to temperature (Moloney, 1991), nitrogen (N) (Whitehead, 1995; Peri et al. , 2001) and water status (Volaire and Thomas, 1995).…”

Daily net canopy photosynthesis (P n ) of cocksfoot (Dactylis glomerata L.) was predicted for combinations of temperature, herbage nitrogen (N) concentration and water status from the integration of models of leaf photosynthesis of the light-saturated photosynthetic rate (P max ), photosynthetic efficiency (a) and the degree of curvature (h) of leaf light-response curves. The effect on P n , maximum P n (P n max ) and the optimum leaf area index (LAI at P n max ) was examined when any one of these factors was limiting. The ranges that gave the optimum values of P n (P n max ¼ 30AE8-33AE5 g CO 2 m )2 d )1 ) for temperature (19-22°C) and N concentration (40-50 g N kg )1 DM) were smaller than those for net leaf photosynthesis. Also, P n fell to 0 at a lower level of water stress (pre-dawn leaf water potential, w lp ¼ )12AE5 bar) than for P max . The canopy photosynthesis model was then used to compare predicted and measured dry matter (DM) production for cocksfoot pastures grown under a diverse range of environmental conditions with field data from New Zealand and Argentina. To predict DM production leaf area index and leaf canopy angle were included from field measurements. The model explained about 0AE85 of the variation in cocksfoot DM production for the range of 6AE5-134 kg DM ha )1 d )1 . The canopy model overestimated the DM production by 0AE10 which indicates that a further P max function for leaves of different ages and a partitioning sub-model may be needed to improve predictions of DM production.

“…When plant attributes are combined in a multi-species pasture, the mixtures typically have greater annual herbage production than conventional grass-clover pastures (e.g. Moloney 1991;Sanderson et al 2005;Tharmaraj et al 2008;Nobilly et al 2013) though not always (e.g. Woodward et al 2013).…”

In the context of dairy grazing systems, pasture mixtures including tall fescue, lucerne and plantain have been identified by animal modelling as having potential to both improve milk production and reduce urinary nitrogen excretion. A grazed paddock-scale trial was established in the Waikato in September 2015 to test this in two short-term grazing trials including these species. This paper presents the pasture production, botanical composition and nutritive value data generated from four pasture mixtures sown in spring 2015 and sampled until autumn 2017 (18 months). The pasture mixtures represented a comparison between perennial ryegrass and tall fescue, with and without the herb narrow-leaved plantain. The inclusion of plantain in grass-lucerne mixtures had a positive effect on firstyear herbage dry matter (DM) production, by ~2.6 t DM/ha/year in ryegrass-based pastures and ~1.6 t DM/ ha/year in tall fescue-based pastures. Where plantain was included, the proportion of grass was reduced by more than half from autumn 2016 through to summer 2016-2017, while the proportion of lucerne was reduced to a lesser degree. The proportion of plantain was 35-70% through most of the first year, declining to
