Growth and persistence of perennial ryegrass lines with different tolerances to "pulling" during grazing

  author={E. R. Thom and V. T. van Vught and Robert J. Mccabe},
The effects of ryegrass genotype, nitrogen (N) fertiliser and soil type on the level of plant losses by “pulling” during grazings were studied over 2 years. Plots of high-endophyte pipeline perennial ryegrass lines, coded A1 and A3, were established on the Dairying Research Corporation No. 2 Dairy in May 1994. Three plots of each line were sown on a Te Kowhai silt loam and three on a Te Rapa peaty silt loam soil. Half the area of each plot received nitrogen fertiliser (30 kg N/ha) after… Expand

Relationship of tillering and morphological characteristics of two perennial ryegrass lines to “pulling” when grazed by dairy cows
It is argued that better anchorage combined with leaves that break more easily when grazed contributed to less pulling of Kiwi ryegrass pipeline selection NZA3 than of NZA1 clumps during dry summers. Expand
Growth and persistence of perennial and hybrid ryegrasses when grazed by dairy cows in the central Waikato region of New Zealand
Abstract A 3‐year plot trial was conducted at the Dairying Research Corporation, Hamilton, New Zealand to compare herbage production, persistence, and crown rust (Puccinia coronatd) resistance in 13Expand
Productivity of grazed perennial ryegrass dairy pastures from different ecotypes under nitrogen and irrigation treatments
Data on the reproductive behaviour of perennial ryegrass cultivars and tillering responses to N applied in spring‐summer, could provide useful selection criteria for persistence under intensive dairying. Expand
Evaluating perennial ryegrass cultivars: improving testing
It is recommended that industry cultivar testing needs to more accurately assess perennial ryegrass persistence, using new protocols including running trials on commercial farms, for more than 3 years, and using mixed swards. Expand
Can pasture persistence be improved through the use of non-ryegrass species ?
Recent discussion about pasture persistence concentrates on pastures based on perennial ryegrass, the most commonly used grass species. This paper raises the question as to whether some of the causesExpand
Dairy farm systems to aid persistence
this manuscript reviews fundamental pasture management principles relevant to pasture persistence. We first note some points of context, within which the debate on pasture persistence is occurring:Expand
Review: The effects of soil compaction on root penetration, pasture growth and persistence
A review of the literature shows that soil compaction by stock treading has been an issue for New Zealand farmers for over half a century. soil compaction restricts root penetration resulting in poorExpand


Renovation of pastures containing paspalum 2. Effects of nitrogen fertiliser on the growth and persistence of overdrilled ryegrass
These experiments confirmed the high summer losses of introduced ryegrass plants as previously reported and confirmed that large growth responses to nitrogen fertiliser by the introduced rYegrasses were insufficient to improve survival. Expand
Management of Lolium perenne/Trifolium repens pastures in the subtropics. II. Effect of summer defoliation, irrigation duration, seedbed preparation and pasture type
Multiple cultivations appear to be the key to appropriate seedbed preparation, with this treatment achieving the highest ryegrass survival rate, lowest summer grass incursion and highest DM yields. Expand
Herbage losses from tiller pulling in a continuously grazed perennial ryegrass sward
Tiller pulling was found to have no effect on either the subsequent autumn-winter tiller density or yields of cuts taken in the following year. Expand
Effect of high rates of nitrogen fertiliser on perennial ryegrass growth and morphology in grazed dairy pasture in northern New Zealand
Nitrogen (N) fertiliser was applied to dairy pastures at rates of 0,200, or 400 kg N/ha per year on farmlets stocked at 3.24 and 4.53 Friesian cows/ha from June 1993 to June 1995, with a post‐flowering increase in tiller density although this increase was enhanced by N. Expand
Management of Lolium perenne/Trifolium repens pastures in the subtropics. I. Effect of defoliation interval, seeding rate and application of N and lime
The best treatment combination for yield gave the highest rate of ryegrass survival and lowest levels of 'summer grass' ingression over the first summer, but under grazing, many plants may have been lost through sod pulling by stock, as roots were more restricted to the surface. Expand
Effect of Argentine stem weevil on vigour of 'Grasslands Roa' tall fescue under dairying in the Waikato.
It was shown that without insecticide protection, tall fescue tiller densities decreased throughout the summer and autumn, however, insecticide treatments failed to increase the dry matter contribution of tallfescue or total pasture production. Expand
Nitrogen Fertilization and Mowing Height Effects on Tensile Strength of Bermudagrass Sod1
Results of the 3-year study showed that N rates of 0.25kg/are produce sod tensile strengths equal or superior to those obtained from rates as high as 1.0 kg/are. Expand
Effects of leaf shear breaking load on the feeding value of perennial ryegrass ( Lolium perenne ) for sheep: I. Effects on leaf anatomy and morphology
Two populations of perennial ryegrass (PRG) (Lolium perenne L.) were selected for low (LS) and high leaf shear breaking load in 1984 at DSIR, Palmerston North and were associated with a significantly lower concentration of sclerenchyma tissues in the leaf cross-sectional area compared with the HS selection.

Variability of leaf shear strength in perennial ryegrass
Abstract Leaf shear strength of perennial ryegrass (Lolium perenne L.) was studied as a possible indicator of the resistance of herbage to breakdown during chewing and rumination. Leaf strength asExpand
Measurement of the shear and tensile fracture properties of leaves of pasture grasses
Investigations indicated that the intrinsic strength of the material being cut is best represented as force exerted during the cut divided by the length of the cutting blade in contact with the material. Expand
