Orchard Grass

Alfalfa and orchard grass should have, in terms of suitability for ensilaging, the appropriate content of soluble sugars, the corresponding dry matter content and low buffer capacity. When using plants that are less suitable for silage, it is necessary to increase dry matter content in the biomass by adding sugar components and enzymes to direct the fermentation process in order to provide quality and stable silage.

Forage Yields

A mixture of timothy, orchard grass, red clover, alfalfa and Ladino clover was seeded on areas of upland and dikeland soil at Nappan, N.S. Over a 3-year period plots were cut at 3-, 4- and 8-week intervals to stubble heights of [Formula: see text] and 3 inches. Comparisons were made of forage yields and species contribution under the various cutting intensities on the two soils. Forage yield was 20 per cent greater on dikeland and seasonal distribution of forage was better on dikeland than the upland area with which it was compared. Similar responses between treatments were obtained on both dikeland and upland. Timothy contribution fluctuated widely between high spring values and low fall values while orchard grass regularly contributed about 40 per cent of the forage material. Alfalfa contributed reasonably well initially, but failed to persist under more intense clipping, particularly on dikeland. Ladino clover increased in relative value during the 3 years, performing better on upland under more intense clipping.

New Host Records

A number of cereals and other grasses were compared as hosts for different isolates of viruses causing Agropyron mosaic (AMV), wheat streak mosaic (WSMV), barley stripe mosaic (BSMV), ryegrass mosaic (RMV) and orchard grass mosaic (OMV). Lolium multiflorum L. was susceptible to all the viruses. The four varieties of wheat tested were highly susceptible to AMV, WSMV and BSMV, but not to RMV or OMV. Clintland oats was susceptible to WSMV, RMV and OMV but not to AMV or BSMV. Lolium perenne L. and Dactylis glomerata L. were infected by RMV and OMV only, Agropyron repens L. Beauv. by AMV only, and Setaria italica L. Beauv. by BSMV only. Brant and Husky barley were slightly susceptible to AMV, but seven other varieties appeared immune. Unusual host records include the infection of Setaria lutescens (Weigel) Hubb. and one plant of Agropyron smithii Rydb. with WSMV, and the infection of Agropyron intermedium (Host) Beauv. with BSMV. A list of differential hosts is proposed.

Organic Fertilisation

A three-year pot experiment carried out in the vegetation hall in 2014–2016 included studying the enzymatic activity of soil, into which various amounts of copper: (100, 200 and 300 mg Cu/kg soil) and organic materials (cattle manure, chicken manure, post-mushroom substrate) were introduced, used separately, at a soil-introduction dose of 2 g C<sub>org</sub>/kg. Copper and organic materials were used once, only in the first year of the study, before sowing test plant orchard grass. In soil collected after the last (fourth) swath of grass in each year of the study, the activity of urease, dehydrogenases, acid, and alkaline phosphatase was determined. Applications of copper to the soil, regardless of its dose, resulted in a decrease in urease, dehydrogenases and alkaline phosphatase and an increase in acid phosphatase activity. The inactivating effect of this metal on the activity of urease, dehydrogenases and alkaline phosphatase increased with the increase of its dose. Organic fertilisation generally increased the enzymatic activity of the analysed soil. In subsequent years of the study, urease and alkaline phosphatase activity decreased, while acid phosphatase activity increased. Dehydrogenase activity did not change significantly in subsequent years of the study.

Abstract Opuntia ficus-indica is highly regarded as an emergency feed for livestock during drought and as a mainstay for the wildlife population in temperate semi-arid and arid parts of the United States. The goal of this study was to assess the effects of replacing alfalfa and orchard grass with different levels of prickly pear on digestion and fermentation patterns. Three forages were evaluated: alfalfa, orchard grass and prickly pear. In order to determine kinetics of digestion, gas volumes were measured after incubation periods of 0, 3, 6, 12, and 24 h. Samples were run in triplicate with 2 blanks for a total of three periods. Data on gas production were fitted to the equation by Ørskov and McDonald (1979) using SAS software 9.4 (P ≤ 0.05; SAS Inst. Inc., Cary, NC) program. The gas volume observed from the soluble fraction ‘a’ and ‘b’ were similar (P &gt; 0.05) for prickly pear amongst all treatments; no difference was observed between alfalfa and cactus. The rate of gas production ‘c’ was higher in cactus (16.5%, h-1) than alfalfa and orchard grass (11.5%, h-1 and 7.7%, h-1, respectively). The extent ‘a +b’ of gas volumes revealed no difference among the test forages. Prickly pear showed a faster rate of degradation compared to alfalfa and orchard grass. A rapid rate of digestion means a faster passage of the material through the digestive tract. Thus, the higher values obtained for the ‘c’ and similar ‘a + b’ parameters in prickly pear compared to alfalfa or orchard grass, may signal it as a good potential alternative feed in arid and semi-arid areas.
