Rye Grass

1. In four different years, swards of perennial rye-grass/white clover were treated with nitrogenous fertilizer (0, 30 or 60 lb. N per acre) in mid-February to produce an early growth of grass. The effect of the time of the first cut, taken in March or April, on the annual yield was studied.2. The total annual yield was reduced when an increasing quantity of grass was removed at the first cut because this interfered with the development of inflorescences and reduced yield at the second cut.3. Fertilizer treatment increased early growth and advanced by 2-14 days the date in spring at which the yield was adequate for grazing; this improvement improvement was small compared with the extent to which this date was affected by differences in the weather from year to year.4. The response in total annual yield to N averaged 17.2 and 14.9 lb. of dry matter per lb. N respectively for the 30 and 60 lb. N per acre applications. The highest responses were measured when little or no grass was removed at the first cut. Where a larger crop was removed at the first cut the response to N was reduced; exceptionally it was negative.

Pot Culture

In the first of two glasshouse experiments, Lolium perenne and Poa labillardieriwere grown separately with three levels of nitrogen, four levels of phosphorus, four levels of sulphur and two levels of potassium in all factorial combinations. There were no major differences in the relative responses of the two species. The root/shoot ratio of Lolium was twice that of Poa at the final harvest. Uptake of sulphur was higher in Lolium at high levels of applied sulphur. In the second experiment, Lolium and Poa were grown in pure and mixed culture at five levels of applied nutrients. Grown alone the yields of both grasses were similar to the first experiment but in mixed cultures the shoot yields of Poa were reduced to 20% of those in pure culture. The success of Lolium was attributed to its larger seed and more rapid early growth. Normally Poa increases in size and numbers to dominate natural grasslands if superphosphate fertilizer is applied and white clover develops. The results suggest that the dominance of Poa in these grasslands could be restricted by establishing a vigorous stand of Lolium at the beginning of arable pasture improvement.

Neotyphodium Lolii

The responses of hexaploid caucasian clover (Trifolium ambiguum) to four contrasting grazing regimes were compared with those of white clover (T. repens) in an endophytic (Neotyphodium lolii) hybrid ryegrass pasture on a fertile lowland site. After 2 years, frequent grazing (set stocking) by sheep reduced caucasian clover cover to 10% compared with 25.5% in infrequent grazing (rotational grazing) treatments (mean spelling time 25 days). Similarly, frequent grazing reduced caucasian clover rhizome plus root dry weight (780 kg DM/ha when sampled to 100 mm depth in frequently grazed plots, compared with 3220 kg DM/ha for infrequent). Under frequent grazing treatments, mean white clover cover was 21%, under infrequent hard grazing it was 26% and under lax infrequent grazing it was 14%. The reduction in ryegrass tiller population from 5720/m2 in the infrequently and laxly grazed treatments to 4150/ m2 in the frequently hard grazed pastures indicated the severity of that hard grazed treatment. These results show that in lowland ryegrass pastures on high fertility sites, the stoloniferous growth form of white clover may be superior to the rhizomatous strategy of caucasian clover when grazing by sheep is frequent throughout spring, summer and autumn.

Persian Clover

Four temperate clovers were grown on a typical rice-growing soil in the Murrumbidgee Valley, New South Wales, to assess their establishment and early growth potential. Subterranean clover (Trifolium subterraneum var. yanninicum) cv. Trikkala, Persian clover (T. resupinatum) cv. Maral, balansa clover (T. michelianum var. balansae) cv. Paradana, and white clover (T. repens) cv. Haifa were sown immediately following a rice crop in autumn of 3 consecutive years. Seven sowing methods were compared, including combinations of surface or drill sowing with land preparation techniques commonly used in rice-farming systems. All cultivars established successfully. Trikkala had the best establishment on the basis of per cent seed sown in year 2, and equal best in years 1 and 3, although Paradana and Maral had higher plant densities at the sowing rates used. Paradana and Maral produced the highest dry matter yields and Haifa the lowest (P<0.05) in the growing period to mid-spring. Sowing method strongly influenced (P<0.05) both establishment and yield of clover. Sowing into a dense rice canopy before harvest severely restricted clover performance, while harvesting rice before sowing greatly improved (P<0.05) clover establishment and dry matter production. Establishment from surface sowing was generally more successful than from drill sowing, although yields with both methods were mostly satisfactory. Establishment and yields were highest after burning stubble, but this effect was variable and not always significant. Sowing after cultivation was not successful, especially in the 2 wetter years, due to poor seedbed preparation and waterlogging.

Germination And Growth

Summary. Austral bracken (Pteridium esculentum) has a major impact on forestry and the pastoral industries in Australia and New Zealand, as does P. aquilinum in parts of the northern hemisphere. There is a large body of, often conflicting, evidence on the toxicity of P. aquilinum to growth of other plants but there is little evidence for P. esculentum. Control of bracken is currently expensive and difficult to maintain as there is neither a marketable product based on bracken, nor a significant use for it on site. Current interest in commercial uses for bracken as mulch or compost requires analysis of the effects of bracken fronds on germination and growth of a representative range of plants. We report the effects of a mulch of chopped recently-dead (standing) bracken fronds on germination and early growth (to 9 or 12 weeks) of white mustard (Sinapis alba), of the improved pasture species, white clover (Trifolium repens) and perennial ryegrass (Lolium perenne), and of 2 native woodland species brown barrel (Eucalyptus fastigata) and yellow teatree (Leptospermum polygalifolium). A control mulch was prepared from chopped recently-dead bracken fronds by boiling and washing to extract possible allelochemicals and destroy associated microbiota. Bracken mulch stimulated seedling growth of white mustard, white clover, perennial ryegrass and brown barrel to a statistically significant, although moderate, extent (8–20%). Shoot length of perennial ryegrass and brown barrel, and leaf number and leaf size of brown barrel were more markedly enhanced (≥30%) by the application of bracken mulch. In contrast, bracken mulch reduced germination of yellow teatree to 25%, and leaf number, during early growth, to about one-third of that in the controls. The effects of bracken mulch may be due to release of active phytochemicals and mineral nutrients, with or without mediation by associated microflora including mycorrhizae. These glasshouse experiments suggest that recently-dead fronds of P. esculentum may prove a generally useful mulch, although monitoring for adverse effects on establishment and growth of particular species will be required.

In this paper, yield and quality of forage following species of forage legumes were evaluated with regard to precipitations: lucerne (Medicago sativa L.), red clover (Trifolium pratense L.), white clover (Trifolium repens L.), kura clover (Trifolium ambiguum M.), alsike clover (Trifolium hybridum L.) and birdsfoot trefoil (Lotus corniculatus L.). The trial was sown in the spring of 2008, evaluated in the period 2009–2011. Analysis of samples was performed with the apparatus NIRS 6500. Following parameters were evaluated: production of dry matter, energy concentration (NEL), contents of fibre and crude protein. The highest three year yield average was measured for lucerne (15.01 t.ha−1), followed by red clover group (9.3–11.8 t.ha−1). Kura clover gained the lowest yield (1.97 t.ha−1). The average crude protein contents (g.kg−1) were: lucerne 211.47, red clover group (184.3–194.8), white clover group (229.1–238.7) and birdsfoot trefoil (204.2). The obtained results indicated that lucerne responded at best to periods of drought. Although the production of dry matter decreased in periods of drought, the canopy of stands remained to be complete in contradistinction to white clover, which partly disappeared from the stand. Red clover and alsike clover disappeared from the stand during the trial.

Growth Of Voids

Some information on the size and density of voids that develop in several high purity metals and alloys during irradiation with neutrons at elevated temperatures has been reported as a function of irradiation parameters. An area of particular interest is the nucleation and early growth stage of voids. It is the purpose of this paper to describe the microstructure in high purity nickel after irradiation to a very low but constant neutron exposure at three different temperatures.Annealed specimens of 99-997% pure nickel in the form of foils 75μ thick were irradiated in a capsule to a total fluence of 2.2 × 1019 n/cm2 (E > 1.0 MeV). The capsule consisted of three temperature zones maintained by heaters and monitored by thermocouples at 350, 400, and 450°C, respectively. The temperature was automatically dropped to 60°C while the reactor was down.
