A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops [PDF]

, 2005
The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment.

The effect of ryegrass mosaic virus on carbon assimilation and growth of ryegrasses

Annals of Applied Biology, 1977
SUMMARYThe growth of simulated swards of Italian and perennial ryegrass, artificially infected with ryegrass mosaic virus (RMV) or RMV‐free, was investigated. During the build up of RMV infection, dry‐matter yield was usually decreased in infected swards, and the effect was confirmed when single vegetative regrowths of swards were investigated in ...

Evaluating Kentucky bluegrass and perennial ryegrass seeding ratios for sod grown on plastic production

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Sod grown on plastic (SOP) is a sod established on a thin layer of growing medium atop a plastic sheet. It can be harvested with minimal damage to the roots, thereby reducing transplant shock. Kentucky bluegrass (KBG; Poa pratensis L.) is a commonly used cool‐season turfgrass species in sod production and sports fields. However, KBG is slow to

Soil biota in grassland, its ecosystem services and the impact of management [PDF]

, 2007
In the search for sustainable grassland systems, self-regulating processes in the soil become increasingly important. Soil biota play an important role in these processes and in the provision of various ecosystem services. For grassland systems important

Timing of cultural and chemical methods to remove perennial ryegrass overseeded in bermudagrass

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Bermudagrass (Cynodon dactylon L.) is a warm‐season grass that is often overseeded with cool‐season perennial ryegrass (Lolium perenne L.) in the fall to provide green cover. Overseeded bermudagrass is desirable from late fall to early spring; however, turfgrass managers face challenges removing it in the spring and summer months.

Winter cover crops alter methanotrophs community structure in a double-rice paddy soil

Journal of Integrative Agriculture, 2016
Methanotrophs play a vital role in the mitigation of methane emission from soils. However, the influences of cover crops incorporation on paddy soil methanotrophic community structure have not been fully understood.

Assessment of the Efficiency of Combined Seeding Rates of Common Vetch and Ryegrass for Controlling Weed Development in Organic Forage Cultivation Systems

Life
Weed suppression is a crucial factor in sustainable agriculture, and optimizing plant mixtures can enhance weed control efficiency. This study evaluates the effects of different mixture ratios of common vetch (Vicia sativa L.) and annual ryegrass (Lolium

Novel genetic engineering technology which increases leaf lipid content modifies the ensiling properties of perennial ryegrass : a thesis presented in partial fulfillment of the requirements for the degree of Masters in Agricultural Science at Massey University, Palmerston North [PDF]

, 2016
A novel strategy to increase the metabolisable energy (ME) yield of pastures has been the development of a genetic engineering technology which increases the leaf lipid content and biomass production of perennial ryegrass (PRG).

Improving Biological Control Outcomes: A New Zealand Perspective

New Zealand Journal of Agricultural Research, Volume 69, Issue 3, June 2026.
This short communication outlines the imperative for advances in classical biological control, often based on molecular technologies, to accentuate the efficacy of impact while being cognisant of the need for biological control safety.
