Horticulture published reports

Within the south-west of Western Australia, in the area encompassed by Bunbury, Margaret River, Albany and Manjimup, the horticultural industries have become of major importance to economic viability and employment opportunities.

The Manjimup Shire grows45 percent of the State's potatoes, 50 per cent profits cauliflowers and 32 per cent profits apples. Other important crops are onions, beans and peas for processing and Chinese cabbage. A range of other horticultural crops are produced on a small scale.

The recent establishment of an Edgell-Birds Eye processing plant at Manjimup will provide a further significant boost to the region. By 1992 this plant …

Improving Lupin Pod Setting And Yield, R J. Delane

Journal of the Department of Agriculture, Western Australia, Series 4

Western Australia's lupin production has grown twenty-fold since 1977. Lupins are now a valuable seed, feed and rotation crop on light-textured neutral and acid soils throughout southern Australia. Nevertheless, both experimental and commercial yields have been variable over sites and seasons. A major cause has been excessive flower and pod abortion on the main stem. Farmers have often commented on well grown lupin crops which appear to carry few pods

Murex Medic : A New Pasture Species, Dennis J. Gillespie

Journal of the Department of Agriculture, Western Australia, Series 4

Murex medic (Medicago murex) is a new species of medic not previously used commercially anywhere in the world. The first variety, Zodiac, was developed by the Western Australian Department of Agriculture and released to seed producers throughout Australia in 1988. Other varieties are being evaluated and further releases are likely in a few years.

Association Of Mesocotyl And Coleptile Elongation With Seeding Vigor In Rice, M. A. Mgonja, R. H. Dilday, S. L. Skinner, F. C. Collins

Journal of the Arkansas Academy of Science

Three experiments were conducted to evaluate the relationship of mesocotyl and coleoptile elongation to seedling vigor and plant height in rice (Oryza sativa). A laboratory experiment was conducted to evaluate the potential lengths of the mesocotyl and coleoptile of semidwarf and standard rice genotypes. Four genotypes exhibited inherent differences in their ability for mesocotyl and coleoptile elongation. The semidwarf genotypes ('M-101 ' and RU 7703008) showed reduced mesocotyls, coleoptiles, and total lengths (mesocotyl + coleoptile); whereas, the tall plant type ('L-201' and 'Labelle') had comparatively longer mesocotyls, coleoptiles, and total lengths. Itis assumed that mesocotyl elongation is the most important …

Seedling Response In A Greenhouse To Four Rates Of Old And New Paper Mill Sludge, Jimmie L. Yeiser

Journal of the Arkansas Academy of Science

Four rates (0, 36, 75, and 11 2 DT/A)of both old and new pulp-mill sludges were tested in a greenhouse for impact on survival and growth of seedlings of loblolly pine (Pinus taeda L). After one growing season no meaningful differences were detected for seedling survival and growth, number off lushes, and decomposition rate for old and new sludges regardless of rate. Seedling foliage showed increases in Mg and Ca and sludges exhibited high pH and increased salinity.

Effect Of Nitrogen Fertilizer On Milling Quality Of Rice (Oryza Sativa), R. H. Dilday

Journal of the Arkansas Academy of Science

The effect of nitrogen fertilizer on milling quality or milling yield of rice (Oryza sativa) was tested for two cultivars, 'Lemont' and 'Newbonnet'. This was an increase in the percentage of broken kernels and a decrease in head rice yield when no nitrogen fertilizer was applied as compared to applying all of the nitrogen at preflood or in split applications. The greater affect was on Lemont, a cultivar that requires a high amount of nitrogen fertilizer for maximum grain yields. Data showed that the percentage of head rice can be reduced by as much as 7 to 22 percent in …

Doublegee demography in cereal crops.

Objective: To measure reproductive output in relation to times of emergence and herbicide application.

Trial No. 88WH10

Growth of doublegee under summer irrigation.

Objectives: A major impediment to achieving biological control of any annual weed in the wheat belt is that the bicontrol agent must have a means of aestivation. Since the only insect to have been introduced to Australia for a the control of doublegee does not aestivate, it was thought that populations could be able to oversummer in irrigated doublegee standards. The aim of this study was to assess the …

Considerations In Breeding Endophyte-Free Tall Fescue Forage Cultivars, Jeffrey F. Pedersen, D. A. Sleper

Department of Agronomy and Horticulture: Faculty Publications

Breeding tall fescue (Festuca arundinacea Schreb.) cultivars that are free of the endophytic fungus Acremonium coenophialum Morgan-Jones and Gams [previously identified and referred to as Epichloe typhina (Fries) Tulasne] is necessary to improve animal performance. The techniques used in developing new cultivars are not greatly different from those used previously, with one exception. Prior to the evaluation of new tall fescue lines or populations, the endophyte needs to be eliminated from the seed or the plants. Several techniques utilizing aging, heat, or chemical treatment are being used to effectively accomplish this in the seed. Methods for permanently eliminating the endophyte …

Levels And Timing Of Nitrogen Fertilizer Applications For Tall Fescue In Central Alabama, J. W. Odom, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Tall fescue (Festuca arundinacea Schreb.), the most important cool season perennial pasture grass in the United States, is generally well adapted to the northern two-thirds of Alabama. Unfortunately, the most commonly grown tall fescue cultivar, Kentucky 31, is of northern origin and is dormant during the winter. To reduce this problem, AU Triumph was selected from Mediterranean germplasm. The Alabama Agricultural Experiment Station released this cultivar to growers in 1981. Compared to Kentucky 31, AU Triumph produces about 80 percent more forage during the winter and produces mature seed about 2 weeks earlier in the spring. Total annual forage production …

Factors Affecting Frost Damage To Wheat In Western Australia, S P. Loss

Division of Plant Research : Technical Report Series

It may at first seem strange that precious research funds are being channelled into a project concerned with frost damage in a country where high temperatures and moisture stress limit the growth of plants for a large portion of the year. But cereal crops are only grown in the temperate zones of the continent during winter and spring when they may be exposed to low diurnal temperatures. In many areas cold damage is irregular and rare,however it limits yields not only by causing actual damage but also by restricting the most effective period for flowering. For muck of the Australian …

Direct Seeding Trees On Farmland In The Western Australian Wheatbelt, J P. Piggott, P H. Brown, M M. Williams

Resource management technical reports

Field and nursery experiments were conducted to determine suitable species, weed control methods, sowing times and seeding techniques. Sowing time was the most significant variable evident in the field experiments. Trees sown in the winter months of June and July out-performed later sowing times. Early sowing of trees in areas of low seasonal rainfall appears to offer considerable advantages for successful establishment over late sowing.
