Understanding Fertilisers - Course Notes, Margaret Graham, John Burt, Neil Lantzke

Horticulture research reports

The aim of the course is to provide you with more detailed information that will allow you to refine and improve your fertiliser program. Applying the correct amount of nutrient increases yield and quality. Over-fertilising is a waste of money and may lead to pollution of groundwater.

Cdna Sequence For The Ribulose 1,5 Bisphosphate Carboxylase/Oxygenase Complex Protein A Protein That Accumulates In Soybean Leaves In Response To Fruit Removal, Paul E. Staswick, Steven J. Crafts-Brandner

Department of Agronomy and Horticulture: Faculty Publications

Soybean (Glycine max L.) transiently accumulates two abundant vegetative storage proteins, VSP A and VSP B, in vacuoles of above-ground vegetative tissues (Wittenbach, 1983; Staswick, 1990). As older leaves and stems become a source of exported metabolites for developing sinks, the VSPs are preferentially degraded and the resulting metabolites are presumably mobilized in the xylem and phloem stream. A striking feature of these proteins is that VSP gene expression is dramatically increased in mature leaves following the remova1 of reproductive sinks (seed pods) and the amount of these proteins increases accordingly (for review, see Staswick, 1994). Other changes …

Purification Of The Major Soybean Leaf Acid Phosphatase That 1s Increased By Seed-Pod Removal, Paul E. Staswick, Chuck Papa, Jing-Feng Huang, Yoon Rhee

Department of Agronomy and Horticulture: Faculty Publications

Fruit removal for 5 weeks after flowering increased acid phosphatase activity 10-fold in soybean (Glycine max 1. Merr. vai Hobbit) leaves compared with normal seed-pod-bearing plants. The major acid phosphatase activity in leaves was purified over 2700-fold, yielding a single polypeptide of 51 kD with a specific activity of 1353 units/mg protein using p-nitrophenylphosphate as the substrate. lsoelectric focusing demonstrated that the purified protein co-migrated with a majority of the activity that increased in leaves following seed-pod removal. lmmunoblot analysis demonstrated that at least part of the increased activity was dueto an increased abundance of the phosphatase protein. In situ …

1. Effects of irrigation on lowbush blueberry yield and quality

2. The Economics of investigating irrigation for lowbush blueberries

3. Phosphorus dose/response curve

4. Winter injury protection by potassium

5. Multiple cropping of wild stands

6. Effect of Boron and Calcium on lowbush blueberry fruit set and yield

7. Comparison of N, NP, and NPK fertilizers to correct nitrogen and phosphorus deficiency

An Inventory And Condition Survey Of Rangelands In The North-Eastern Goldfields, Western Australia, H J. Pringle, S A. Gilligan, A M E Van Vreeswyk

Technical Bulletins

The inventory and condition survey of the north-eastern Goldfields, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1988 and 1990, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers about 100 …

An Inventory And Condition Survey Of The Murchison River Catchment, Western Australia, Peter James Curry, A L. Payne, K A. Leighton, P Hennig, D A. Blood

Technical Bulletins

The inventory and condition survey of the Murchison River catchment and surrounds, undertaken by the Department of Agriculture between 1985 and 1988, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed by field work during 1985-88 …
