Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

Bulletin No 4146 - Commercial Production Of Pawpaws In Western Australia, J. R. Burt, B. L. Toohill

Bulletins 4000 -

The papaw (Carica papaya L.) is a native plant of Central America. It produces its highest yields of good quality fruit in tropical regions.

The tree is short-lived and rarely produces crops for more than two or three years. It is quick growing and soon reaches a maximum height of 5 to 7 m. It is usually unbranched, but may branch after either injury to the top or cutting back.

Formation And Control Of Chlorophyll, Solanine Alkaloids, And Sprouts Of Potato (Solanum Tuberosum L.) Tubers And Carbonyl Compound Of Tomato (Lycopersicon Esculentum Mill.) Fruits, S. J. Jadhav

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Part I. Formation and control of chlorophyll, solanine alkaloids, and sprouts of potato (Solanum tuberosum L.) tubers

Incorporation of radioactive carbon from acetic acid-2-¹⁴C (sodium salt), β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C, L-leucine-U-¹⁴C, L-alanine-U-¹⁴C, and D-glucose-U-¹⁴C into the predominant glycosidic steroidal alkaloids, ⍺-solanine and ⍺-chaconine of potato sprouts was 4.88, 9.0, 15, 24, and 20 times less than that of mevalonic acid (MVA)=2-¹⁴C (DBED salt), respectively. The efficiency ratio revealed that β-hydroxy-β-methylglutaric acid (HMG)-3-¹⁴C was incorporated via acetate or acetoacetate. The distribution of radioactivity originated from D-glucose-U-^{14 …}

Fertiliser Recommendations For Citrus : Detailed Fertilizer Programmes For Citrus Growers, N H. Shorter, J. E. L. Cripps

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

CITRUS growers should adopt a well balanced fertiliser programme to safeguard tree health, cropping and fruit quality. While moderate dressings are a wise insurance in most situations the rates required vary with tree age and soil type.

Growing And Marketing Yates For Profit, Frank Melville

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

THE YATES APPLE is a late maturing red variety which because of its good storage qualities enjoyed a prominent place on the late market for many years.

The trees grow and crop well, the only disabilities are insufficient colour under some circumstances, small size fruit and a tendency to shrivel.

All these troubles can be successfully overcome by appropriate management.

Chemical Thinning Of Plums And Peaches, J E L Cripps, K. T. Whitely

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

DURING the past decade the acreage of Japanese plums in Western Australia has increased by 10 percent, and production has risen by nearly 40 per cent.

Furthermore, almost 30 per cent, of our trees were still classified as non bearing in 1966, so rapid increases in production are certain to be recorded within the next few years.

Stop-Drop Sprays For Jonathan And Delicious Apples, N H. Shorter, J. Cripps

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

STOP-DROP sprays prevent excessive pre-harvest drop of Jonathan and Delicious apples.

Recent research has thrown more light on the best methods of employing these materials.

TWO CHEMICALS used as "stop-drop" sprays are available commercially in Western Australia. One of these, alpha napthalene acetic acid (NAA), is also well known as a thinning spray for apples.

Pruning Citrus Trees. 2. Pruning The Mature Tree, D B. Argyle

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

EXAMINATION of a mature tree in full production will show the natural pattern of growth already explained.

It will be seen that over the years the frame has developed by a system of layers with new growth, stimulated by sunlight, constantly appearing on the top side of the older wood.

Eventually the terminal portions of the older layers are weakened by lack of light, they become unproductive and in turn adversely affect the general fruitfulness of the rest of the tree by shading and crowding.

Delayed Foliation In Apple Trees, J E L Cripps

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

DELAYED foliation refers to the late leafing out and production of small leaves by fruit trees.

However, the weak and protracted blossoming which precedes the appearance of the leaves has more serious consequences for it may lead to a reduced set of fruit.

Spray Thinning Of Japanese Plums, J E L Cripps

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

THE hand thinning of Japanese plums is the most tedious work which the orchardist is called upon to undertake so that any method of crop reduction other than by hand should be welcome.

Growers may, therefore, be pleased to know that in experiments conducted by the Department of Agriculture several varieties have been successfully spray thinned. The material used was D.N.B.P. (Dinitro secondary butyl phenol).

Spraying with this material considerably reduces but does not eliminate hand thinning.

Hormone Sprays For Apricots, J E L Cripps

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

VARIOUS hormone sprays have been applied to apricots with the object of increasing fruit size and hastening maturity, and of these 245TA, the tri-ethanol amine salt of 245 trichlorophenoxyacetic acid, has in general, proved the most successful.

The increase in fruit diameter obtained with this spray in Western Australia has varied between 5 and 15 per cent, and is due to an increase in the size of the cells within the fruit, not to the production of a greater number of cells.

Bulletin No 80 - Cultivation Of Sugar Beet, Percy G. Wicken

Bulletins 1 - 2999

The beet belongs to the Chenopodiaceae or Salsolaceae, an order of plants which include among them many of the native saltbushes. The sugar beet (Beta vuigaris crassa) is supposed to have been developed from the wild beet (Beta vulgaris maritima), which is indigenous to the countries along the coast of Southern Europe. it is a biennial plant—that is, of two years' duration. The first year it produces a full-sized root, the second year it produces its seeds, and then dies off. Sometimes a few plants Produce seed the first year, but this is only on account of the seed being …
