“…Sood (1981) reported that increase in nitrogen levels from 60-120 kg N/ha brought significant increase in plant height, green as well as dry fodder during all the 3 years of study. The findings of the present experiment also in conformity with Kunelius (2004). Seed rate also have a positive role in increasing the plant height.…”

An experiment was conducted in 2000 to compare simple visual estimate, sward height and rising plate meter (RPM) methods for determining forage biomass in mixed-species, naturalized, rotationally grazed dairy and beef pastures. Measurements were taken pre-and post-grazing on 10 sampling dates at the dairy pasture, and post-grazing at 13 sampling dates at the beef pasture. For each sampling date, the effectiveness of each method for estimating the actual biomass from a quadrat was evaluated using regression analysis. The results for the visual estimate method were not consistent, with non-linear relationships occurring early and late in the season. While the meter stick was most effective in the dairy pasture, the RPM was most effective in the beef pasture. Species composition and structural characteristics of the stand were important factors affecting accuracy of biomass estimation. Equations developed for each method and site using data from all dates had low R 2 -adjusted values, and were unreliable predictors of biomass. The results from individual sites and dates were extremely variable, with no single method effective in all circumstances. To estimate forage biomass in mixedspecies, naturalized pastures, standard quadrat harvesting remains the most reliable method, provided that enough quadrats are clipped to adequately represent a given area.

“…Perennial ryegrass ( Lolium perenne L.) is grown widely in temperate regions and is the mainstay of pastures in much of Europe and New Zealand. Documentation of the agronomic and ecophysiologic attributes of Lolium species for growing conditions in eastern North America is limited (Jung and Shaffer, 1993; Jung et al, 1996; Hall et al, 1998; Kunelius et al, 2004). Jung and Shaffer (1993) found that perennial ryegrass grown in mixture with alfalfa ( Medicago sativa L.) produced greater yield and contributed to stands with fewer weeds compared with stands containing timothy ( Phleum pratense L.).…”

Regrowth Interval Influences Productivity, Botanical Composition, and Nutritive Value of Old World Bluestem and Perennial Ryegrass Swards

Botanical composition of pasture in much of the Appalachian Region varies as weather patterns interacting with abiotic and biotic factors create conditions allowing a range of plant species to occupy temporal and spatial gaps in the stand. Field-grown old world bluestem [Bothriochloa caucasia (Trin.) C.E. Hubb.] or perennial ryegrass (Lolium perenne L.) were defoliated at fixed time intervals (1-, 2-, or 4-wk for old world bluestem and 2-, 4-, or 6-wk intervals for perennial ryegrass). Herbage mass, sward botanical composition, and estimates of nutritive value were determined. White clover (Trifolium repens L.), black medic (Medicago lupulina L), and various common forbs and grasses volunteered in all stands. Old world bluestem yields ranged from 3.38 Mg ha 21 (1-wk regrowth interval in 2002) to 9.42 Mg ha 21 (4-wk regrowth interval in 2000). Perennial ryegrass yield increased with increasing regrowth interval in 2002, ranging from 3.16 to 7.29 Mg ha 21 . The longest regrowth interval did not necessarily lead to the greatest productivity. Old world bluestem swards clipped at 4-wk intervals decreased 60% by the third growing season, whereas perennial ryegrass swards clipped at 6-wk intervals increased by 37%. The proportion of encroaching species increased substantially in perennial ryegrass but not old world bluestem swards by 2002, suggesting that combined effects of repeated defoliation and weather influenced sward composition and productivity. Choice of plant resource, timing and intensity of defoliation, and very likely nutrient inputs coinciding with requirements of sown species could influence sward composition and help manage diversity to sustain productivity.

Management of Italian and Perennial Ryegrasses for Seed and Forage Production in Crop Rotations

Abstract: Italian ryegrass (Lolium multiflorum Lam.) and perennial ryegrass (L. perenne L.) can be grown for seed and forage in cold winter regions provided the stand persists well over winter.
