Validation Of A Technique For Estimating Alfalfa (Medicago Sativa) Biomass From Canopy Volume, Christopher G. Misar, Lan Xu, Arvid Boe, Roger N. Gates, Patricia S. Johnson Jun 2019

Validation Of A Technique For Estimating Alfalfa (Medicago Sativa) Biomass From Canopy Volume, Christopher G. Misar, Lan Xu, Arvid Boe, Roger N. Gates, Patricia S. Johnson

Arvid Boe

Determining biomass production of individual alfalfa (Medicago sativa L.) plants in space planted evaluation studies is generally not feasible. Clipping plants is time consuming, expensive, and often not possible if the plants are subjected to grazing. A regression function (Bʹ = 0.72558 + 0.11638 × Vʹ) was developed from spaced plants growing on rangeland in northwestern South Dakota near Buffalo to nondestructively estimate individual plant biomass (B) from canopy volume (V). However, external validation is necessary to effectively apply the model to other environments. In the summer of 2015, new data to validate the model were collected from spaced plants near ...


Identifying And Characterizing Salt-Tolerant Alfalfa (Medicago Sativa Subsp Falcata Germplasm, Katelin E. Frerichs, Lan Xu Jan 2018

Identifying And Characterizing Salt-Tolerant Alfalfa (Medicago Sativa Subsp Falcata Germplasm, Katelin E. Frerichs, Lan Xu

Natural Resource Management Faculty Publications

Soil salinity limits plant growth and crop production. More than 20% of cultivated land worldwide is affected by salinity. The situation is becoming more severe due to shifts in precipitation and evaporation patterns and improper irrigation. There is an urgent need to develop salt-tolerant, economically valuable plants to minimize the loss of and to sustain agricultural production. Alfalfa is one of the most extensively cultivated forage crops. Some yellow-flowered alfalfa (Medicago sativa subsp. falcata) have exhibited morphological and physiological drought tolerance. Since soil salinity is associated with physiological drought, it is reasonable to expect that these drought tolerant falcata populations ...

Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta Dec 2009

Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta

Bulletins 4000 -

Lucerne, often regarded as the queen of forages, has been used in agriculture for centuries. In Western Australia, however, its potential has never been fully realised despite its well-documented ability to dewater soils and reduce groundwater recharge. Over the years adoption has been limited by a range of factors including pests and diseases, soil acidity, grazing management and economics. During the last decade research has addressed these issues, paving the way for much greater impact at the farm and catchment level.

The Good Food Guide For Sheep : Feeding Sheep For Meat Production In The Areas Of Western Australia, Keith Croker, Peter Watt, Department Of Agriculture And Food, Western Australia Sep 2001

The Good Food Guide For Sheep : Feeding Sheep For Meat Production In The Areas Of Western Australia, Keith Croker, Peter Watt, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

The Good Food Guide for Sheep has been produced to provide Western Australian farmers with a concise compilation of current information on feeding sheep for meat production. Although there are already numerous publications about sheep nutrition,many of them relate to wool production, reproduction or drought feeding, or they concentrate on particular feeds or feeding systems.

This book contains information on a wide range of feeds and feeding methods. Just as there is no single ‘best’ sheep breed for meat production, there is no ultimate feed regime for sheep for growth.


Forage Quality Of Genetically Diverse Alfalfa Germplasms At Four Phenological Growth Stages, Andrew W. Lenssen, E. L. Sorensen, G. L. Posler Dec 1989

Forage Quality Of Genetically Diverse Alfalfa Germplasms At Four Phenological Growth Stages, Andrew W. Lenssen, E. L. Sorensen, G. L. Posler

Andrew W. Lenssen

Forage quality of various alfalfa (Medicago sativa L.) cultivars has been determined under different environmental conditions, and numerous trials with alfalfa have documented an inverse relationship between forage quality and maturity. Little information is available, however, regarding the comparative forage quality of the germplasm sources from which most USA cultivars were developed. We compared forage quality of these germplasm sources at four phenological stages under disease- and insect-free conditions in a greenhouse. Germplasm sources (cultivars) tested were: Indian (Sirsa # 9), African (African), Peruvian (Hairy Peruvian), Flemish (DuPuits), Turkistan (Lahontan), Chilean (Kansas Common), M. varia (Grimm), and Ladak (Ladak). Four harvests ...

W.A. Alert For Aphid On Lucerne, Department Of Agriculture, Western Australia Jan 1977

W.A. Alert For Aphid On Lucerne, Department Of Agriculture, Western Australia

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

The spotted alfalfa aphid which is devastating lucerne crops in the Eastern States, could be introduced to Western Australia on lucerne hay which is fed en route to imported livestock. The Department of Agriculture has therefore alerted all inspection points about the possible danger.

The Department of Agricultureis maintaining traps specifically for the aphid, and has found no evidence of it yet.


The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis Jan 1974

The Place Of Lucerne In Western Australian Agriculture, N J. Halse, C. M. Francis

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

Lucerne, the world's most important fodder legume, has never won largescale acceptance in West Australian farming, largely because of our success with productive subterranean clover pastures. But recent disease problems on sub. clover stands have led to greater interest in alternative species, especially lucerne, for higher rainfall areas.

This article summarises our knowledge of lucerne establishment and management in W.A. and reviews current research aimed at achieving better results from lucerne.

Management Of Dry Land Lucerne In The South-West, R Sprivulis

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

MANY dry land lucerne stands have been successfully established in the dairying areas of the South-West.

With good management these can remain productive for many years; poor management can greatly reduce their productive life.


Lucerne Establishment In High Rainfall Dairying Districts, R Sprivulis Jan 1970

Lucerne Establishment In High Rainfall Dairying Districts, R Sprivulis

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

LUCERNE is one of the oldest of perennial forage plants. It originated in the Middle East and because it flourishes under a wide range of climatic and soil conditions it is being grown in many parts of the world.

Lucerne was introduced to Australia in the early years of British settlement. The original introductions proved suitable for the alluvial flats of the Hunter and Peel River valleys of N.S.W.

Lucerne is basically a summer growing legume with or without winter dormancy.


Canberra Creeping Lucerne Outyields Hunter River In Denmark Trial, F E. Ryan Jan 1968

Canberra Creeping Lucerne Outyields Hunter River In Denmark Trial, F E. Ryan

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

LUCERNE is successfully grown as a fodder crop in high rainfall areas in Western Australia without irrigation and there is scope for expansion.

Establishment problems can be largely overcome by choice of a well drained site, spring planting to avoid weeds and pests, an application of 1 ton of limestone to the surface 5 to 6 inches of soil before sowing, and sowing of innoculated and pelleted seed.


Lucerne Establishment On The West Midland Sandplain, J W. Gartrell Jan 1964

Lucerne Establishment On The West Midland Sandplain, J W. Gartrell

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

WEST of Dandaragan and the Midland line from Watheroo to Mingenew there are four million acres of scrubplain commonly called the Western Sandplain.

All virgin soils in this region are acutely nitrogen deficient so that the agricultural future of the region depends on how successfully legumes are grown.


Foliage Diseases Of Lucerne, S C. Chambers Jan 1963

Foliage Diseases Of Lucerne, S C. Chambers

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

Lucerne is subject to several foliage diseases in Western Australia, the more important being common leaf spot, rust and downy mildew.

These fungal diseases are all favoured by humid conditions and are especially prevalent in lucerne stands growing under irrigation.

Bulletin No. 31 - Time To Harvest Lucerne. Mulching., J. W. Sanborn

UAES Bulletins

The opinion has prevailed in scientific as well as in practical circles, that hay cut before or during bloom is more valuable, pound for pound, than when cut at a later period, and it is even maintained that the gross product per acre is more valuable. The old assumption, now somewhat modified, that as plants mature a part of the starch and sugar is converted into fibre, and that the nutrition of the stem is moved into the seed, led to the belief that early-cut hay was both more digestible and more valuable than that cut at a later period ...
