The Effect Of Long-Term Grazing Treatments On The Establishment Of Woody Plants In A Southern African Savanna, G N. Smit, N.F G. Rethman Jun 2024

The Effect Of Long-Term Grazing Treatments On The Establishment Of Woody Plants In A Southern African Savanna, G N. Smit, N.F G. Rethman

IGC Proceedings (1977-2023)

Eight paddocks which were debushed to an open savanna during 1935/36 and subsequently grazed annually during different seasons by steers were surveyed after a period of 54 years. Though woody plants have increased in all the paddocks, regardless of the grazing treatment, the rate of woody plant establishment was notably higher in those paddocks that received a more intense annual grazing treatment. This effect was most noticeable in those paddocks of which the mean Animal Unit-grazing days ha-1 exceeded 100 days annually. These results confirm the existence of a positive linear relationship between the severity of the grazing treatment and …

Some Improvable Points For Better Utilization Of Reed Canarygrass Cultivars In Japan, T Otani, M Ito, Y Maeda, Y Kurihara

IGC Proceedings (1977-2023)

Relationships among growth stage, herbage quality, and dry matter accumulation of reed canarygrass cultivars were investigated in a rainy mountainous district of Japan. Fiber content accumulated during the primary growth correlated with some growth characters of this grass, especially with preferential culm expansion, so that total amount of cell wall constituents reached a remarkably high level about the time when culm/foliage (C/F) ratio in dry matter was elevated above 1.5. In aftermaths, whose early regrowth went on rather quickly, dry matter accumulation began to decline at the stage that C/F ratio of standing crop became ca. 1.0 and fiber content …

IGC Proceedings (1977-2023)

The main objective of this study was to evaluate the effectiveness and improved productivity of reduced tillage pasture renovation methods in the establishment of triple species pasture mixtures into an existing naturalized stand. Experimental treatments, 2 (low and high stocking rates) by 2 (frost- and sod-seeding methods) factorial with an additional non-renovated pasture control treatment, were arranged in a randomized complete block design with two replications. Despite the fact that high stocking rates resulted in reduced herbage yield, animal production per hectare was substantially improved in the establishment and the first postestablishment year. Sod-seeding was the most effective establishment method …


Dryland Grazing Evaluation Of Grasslands Gala Grazing Brome, B L. Sutherland Jun 2024

Dryland Grazing Evaluation Of Grasslands Gala Grazing Brome, B L. Sutherland

IGC Proceedings (1977-2023)

Grasslands Gala grazing brome (Bromus stamineus), was evaluated for seasonal production and persistence under dryland conditions. Gala was compared with cultivars from three different Bromus species and a high endophyte ryegrass, under three sheep grazing managements which varied in duration and intensity. Seasonal herbage yields indicated that Gala persisted under all managements, but was more productive under short and medium rotation grazing than long rotation lax grazing. Results of this five year evaluation indicate that Gala compares favourably with existing cultivars, with its broad range of tolerances making it a desirable option as a perennial in temperate dryland pastoral …


Lamb Performance On Russian Wildrye And Russian Wildrye-Legume Mixtures, David W. Koch, Limei Yun Jun 2024

Lamb Performance On Russian Wildrye And Russian Wildrye-Legume Mixtures, David W. Koch, Limei Yun

IGC Proceedings (1977-2023)

Alfalfa, sainfoin and cicer milkvetch provided relatively little increase in forage production, however, they improved forage palatability and quality, increasing total forage consumption. Over years 3 through 5 of the stand, lamb production per hectare was more than doubled with alfalfa and sainfoin, compared with Russian wildrye (RWR) alone. Cicer milkvetch was relatively slow to establish and did not contribute significantly to mixture quality until Year 5. Alfalfa was more competitive to RWR than sainfoin.

IGC Proceedings (1977-2023)

An experiment was conducted to evaluate the effect of different cutting regimes on productivity and complementarity between oat and vetch in a mixture. The treatments were allocated in a factorial design on a split-split-plot disposition: they were 3 cutting frequencies (each 35, 70 and 105 days), 3 cutting heights (2, 8 and 14 cm above ground) and 3 crops (oat, vetch and the 1:1 mixture). Forage production (dry matter per hectare) and complementarity between species Relative Yield Total (RYT) were evaluated. The highest forage production (p- 0.05) was obtained with a cutting height of 2 cm and a frequency of …


Grazing Sheep On Revegetated Saline Pastures: Effects Of Season And Grazing On Morphology And Nutritive Value Of Saltbush, Atiq Ur Rehman, J B. Mackintosh, B E. Warren, D R. Lindsay Jun 2024

Grazing Sheep On Revegetated Saline Pastures: Effects Of Season And Grazing On Morphology And Nutritive Value Of Saltbush, Atiq Ur Rehman, J B. Mackintosh, B E. Warren, D R. Lindsay

IGC Proceedings (1977-2023)

This experiment was designed to determine the thickness of saltbush (Atriplex amnicola) stem grazed by sheep, grazing pressure on saltbush in the presence of understorey and the effect of season on the nutritive value of saltbush. Four 0.9 ha plots of Atriplex amnicola were grazed by a group of 10 Merino wethers each. The results indicated that the maximum diameter of stem selected by sheep under extreme conditions was only 1.5 mm. The number of stems chewed per 0.1m2 quadrat were 0.8, 9.6, 20.1 and 18.0 (P<0.05) after 2, 4, 6 and 8 wk. From January to June the nitrogen content (14 to 30 gkg-1) and DMD (0.65 to 0.72) of saltbush leaves remained high. These results suggest that in the presence of understorey the grazing pressure on saltbush was least and increases when the feed from understorey was exhausted. The nutritional value of saltbush did not deteriorate severely during the summer and autumn period.

Establishment Vigor Of Endophyte Free And Endophyte Infected Tall Fescue Cultivars In Southern Ohio, C D. Penrose, H M. Bartholomew, R M. Sulc, E M. Volborn

IGC Proceedings (1977-2023)

Eleven cultivars of tall fescue (Festuca arundinacea, Schreb.) and two cultivars of orchardgrass (Dactylis glomerata L.) are part of a study to evaluate yield, establishment vigor, persistence and palatability under autumn stockpiling conditions. Included in the study are two endophyte infected-cultivars of tall fescue to compare interactions with endophyte free and infected cultivars. The results demonstrate that the newer endophyte-free and low-endophyte tall fescue cultivars evaluated are similar to other orchardgrass and endophyte-infected tall fescue cultivars in establishment vigor and early growth the year following establishment.

The Potential Of Winter Rye Cultivars In The Gauteng Province Of South Africa, C C. Botha, N.F. G. Rethman

IGC Proceedings (1977-2023)

Trials were conducted at the Hatfield Experimental Farm to evaluate eight rye cultivars (Secale cereale) in terms of production and development during different seasons. These consisted of a pot experiment, comparing two water regimes, and a field trial, comprising different planting dates, in order to observe phenological development. SSR 729, a South African winter rye, and imported cultivars compared favourably with the traditional cultivars. The winter rye cultivars are good substitutes for the “old” cultivars for the production of green forage in the autumn/winter period.

Productivity Of Silphium Perfoliatum L. In Low Input Agricultural Systems, G Pichard, R Cussen, F Moore

IGC Proceedings (1977-2023)

There is a large area in the coastal region of southern Chile affected by low productivity of soils and severe climatic limitations, which is owned mainly by small farmers. This research was conducted with dairy farmers producing an average of 20,000 liters/year whose main problem is cattle underfeeding because of severe seasonal cycles in pasture growth and extended overgrazing of natural grasslands of low production potential. Silphium perfoliatum L. is a perennial forage species that grows well during the summer period when grasslands have stopped their growth due to moisture stress and high temperatures. Based on the agronomic results and …


Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt Jun 2024

Separate Harvest Of Leaves From The Stems Of Lucerne Stands, L Schmidt

IGC Proceedings (1977-2023)

Lucerne leaves have significantly higher crude protein and lower crude fibre contents than the stems. The present methods for separating the leaves from the stems have serious deficiencies. Early harvesting, for example, weakens the lucerne stand, and sifting after artificial drying impairs quality. Above that, preparation of leaf protein concentrates is rather expensive. Field trials with a pronged cylinder which strips the leaves from the stems produced leaf yields of ž 80 % with a stem portion of £ 15 % (containing ž 26 % crude protein and £ 18 % crude fibre in the dry matter). Lucerne leaves can …

Extending Utilization Of Georgia 5 Tall Fescue In The Lower Southeastern United States, R D. Lee, R N. Gates, J H. Bouton

IGC Proceedings (1977-2023)

In the southeastern United States, warm season perennial grasses such as bermudagrass (Cynodon dactylon [L.]Pers.) and bahiagrass (Paspalum notatum Flugge) predominate permanent pastures. During dormancy, winter annuals are either over-seeded on permanent pastures or grown on prepared seedbeds for winter pasturing of animals. In addition, cattlemen feed hay cut from warm-season grass production. Cattleman and hay producers have lacked a dependable perennial cool season grass that could be utilized in addition to or in place of winter annuals or hay. High temperatures, pests, droughty conditions and competition from warm season species undermine the persistence of cool season grasses. …
