Composition of herbage in Pinus roxburghii Sargent stands: basal area and importance value index
In the present study basal area and Importance Value Index (IVI) attributes of herbage were investigated in chir pine (Pinus roxburghii Sargent) stands of three different ages and also in open grassland in the sub-tropical region of Himachal Pradesh (India) during growing season (June to September). A higher basal area of the herbage was recorded in open grassland as compared to chir pine stand...
متن کاملEffects of cattle grazing on herbage quality in a herbaceous Mediterranean rangeland
The main objective of this study was to determine to what extent grazing pressure and timing modulate the seasonal progression of herbage quality in hilly Mediterranean grassland systems. The study was conducted during six consecutive years between 2003 and 2008 at the Karei Deshe experimental farm, in eastern Galilee, Israel, dominated by rich hemicryptophytic grassland. Treatments included tw...
متن کاملComparison of grassland management systems for beef cattle using self-contained farmlets: effects of contrasting nitrogen inputs and management strategies on nitrogen budgets, and herbage and animal production
Past research on nitrogen (N) inputs, losses and surpluses focused on separate components of grassland management, i.e., grazed or cut swards and the impact of fertiliser or slurry applications. In practice, however, grassland is both grazed and cut for conservation, and N fertiliser is supplied from both organic and inorganic sources. A whole systems approach was used to evaluate the effects o...
متن کاملThe Efficient Use of Grass.
The efficient use of grass" By W. F. RAYMOND, The Grassland Research Institute, Hurley, Berks. The output of animal products from grassland depends on the quantity and quality of herbage produced, and on the efficiency of utilization of this herbage by the animal; these factors interact, herbage production being affected by method and intensity of use, and efficiency of utilization by the overa...
متن کاملLiver copper concentration in cattle and herbage copper, sulphur, iron and molybdenum concentrations on commercial farms in the Wairoa region
Seasonal changes in herbage elements (Cu, Mo, S, Fe), pasture growth, and soil moisture were measured and their relationships with liver Cu concentration in weaner heifers (n=10–12) and breeding cows (n=10–12) were determined on 7 commercial farms in the Wairoa region. Liver biopsy samples were collected at 2 to 4 monthly intervals and herbage and soil moisture monthly from spring 1996 to sprin...
