Hydroponic And Soilless Culture Systems And Transplant Practices Influence Production Of Basil (Omicum Basilicum L.), Samuel Warren Edward Doty May 2020

Hydroponic And Soilless Culture Systems And Transplant Practices Influence Production Of Basil (Omicum Basilicum L.), Samuel Warren Edward Doty

Graduate Theses and Dissertations

Two controlled-environment greenhouse experiments evaluated (1) plant growth and morphology of basil (Omicum basilicum L.) grown in three different hydroponic and soilless substrate systems and (2) seedling tray cell-count and transplant date into hydroponic culture effects on basil growth and yield at harvest. For the first experiment, four basil cultivars (‘Genovese’, ‘Mrs. Burns Lemon’, ‘Sweet Thai’, and ‘Cinnamon’) were grown in deep flow technique (DFT) hydroponics, nutrient film technique (NFT) hydroponics, and a novel shallow aggregate ebb-and-flood (SAEF) soilless substrate system and were harvested after 21 d. Plant yield and morphological characteristics measured at harvest included shoot fresh mass, shoot …


Historical Common Names Of Great Plains Plants, With Scientific Names Index. Volume Ii: Scientific Names Index, Elaine Nowick Mar 2015

Historical Common Names Of Great Plains Plants, With Scientific Names Index. Volume Ii: Scientific Names Index, Elaine Nowick

Zea E-Books Collection

Containing thousands of entries of both vernacular and scientific names of Great Plains plants, the literature that informs this exhaustive listing spans nearly 300 years. Author Elaine Nowick has drawn from sources as diverse as Linnaeus, Lewis and Clark, and local university extension publications to compile the gamut of practical, and often fanciful, common plant names used over the years. Each common name is accompanied by a definitive scientific name with references and authority information. Interspersed with scientifically-correct botanical line drawings, the entries are written in standard ICBN format, making this a useful volume for scholars as well as lay …

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey Jan 2011

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at …


Alstroemeria, Aileen Reid Oct 2006

Alstroemeria, Aileen Reid

Bulletins 4000 -

About 60 species of Alstroemeria grow wild in South America, in habitats ranging from the snowline of the Andes and high mountain plateaus down through the highland forests to the coastal deserts.

A member of the lily family, Alstroemeria grows from a rhizome that also develops tuberous storage outgrowths and fleshy roots. The aerial shoots can be either vegetative or reproductive. Normally shoots that have unfolded more than 30 leaves will not flower and remain vegetative.

The leaves of Alstroemeria are unusual in that they rotate through 180 degrees as they unfold, so that the upper surface becomes the lower …


Producing Pulses In The Southern Agricultural Region, Peter White, Mark Seymour, Pam Burgess, Martin Harries Apr 2005

Producing Pulses In The Southern Agricultural Region, Peter White, Mark Seymour, Pam Burgess, Martin Harries

Bulletins 4000 -

The development of pulses in Western Australia has undergone tremendous advances over the past 12 years. From a tiny industry in the early 1990’s where the knowledge of both scientists and farmers was very limited, we now have a robust industry with production packages and improved varieties for all the grain legumes species that are well suited to our environment.

This book, which is both comprehensive and practical, collates much of the information gathered through pulse research and commercial experience over the past 10 years and will be valuable to all pulse growers, agronomists, students and industry advisors alike. The …

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon Jan 1989

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon

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

Horticulture is an intensive, high value form of agriculture highly dependant on the availability of good water supplies for the year-round production of fresh produce. Production increase in Western Australia and the encouragement and development of export markets has caused rapid expansion if the industry in recent years.

Expansion is expected to continue, placing severe pressure on available water supplies and suitable land close to markets. At present' 90 per cent of the Stase's horticultural land is on the Swan Coastal Plain and minor selected hills areas around Perth.


Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd Jan 1989

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd

Experimental Summaries - Plant Research

Trials : 88BY26, 88PE34, 88MD35

Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.

Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …
