Lighting Strategies for Ornamental Crop Production
The ornamental horticultural industry is diverse and made up of flowering potted plants, cut flowers and bedding plants. Ornamentals have specific lighting requirements needed to grow high quality and consistent crops. Since many bedding plant varieties are started in winter, lighting becomes important for managing early growth stages and to ensure products are in a condition ready to be shipped ...

5 tips on how to light your hemp crop for maximum yields, quality and potency
Lighting for commercial hemp production – 5 tips on how to light your hemp crop for maximum yields, quality and potency. We know that light is essential for plant growth, and for a plant such as hemp, which is adapted to high light levels, and where yields and quality are heavily influenced by light intensity – having supplemental or a high-quality sole source lighting systems is ...

Peppermint productivity and oil composition as a function of nitrogen, growth stage, and harvest time
The commercial production of peppermint (Mentha x piperita L.) is concentrated in more northern latitudes worldwide (north of the 41st parallel), including the United States. This 2-yr field study in Mississippi evaluated the effect of N (0, 80, and 160 kg/ha), growth stage (bud formation and flowering), and harvest time or cut (first cut in mid-July, second cut beginning of October) on ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

A method to predict weekly strawberry fruit yields from extended season production systems
In major strawberry (Fragaria x ananassa) production areas, fruit are harvested continuously for 4 to 6 mo. During the season, weekly yields vary. To improve weekly forecasts, a yield prediction equation was developed for ‘Strawberry Festival’ using input variables derived from flower counts and temperature data over two seasons in Florida. Weekly yields are dependent on the number, size, and ...

Autumn Strawberry Update: the chances of botrytis and rots developing on the fruits have increased due to weather
Soft Fruit Agronomist, Dr Neil Holmes, gives an autumn strawberry update. As strawberry crops approach the autumn season, several challenges remain for late 60-day June bearer and ever bearer crops. Inclement weather over recent weeks has increased the chances of botrytis and rots developing on the fruits. By the time grey mould has developed on the fruit, there is little that can be done to ...

A Rose by any other Name
Bohemian Flowers on the south shores of Lake Naivasha, Nakuru County, Kenya, is today one the largest rose and mixed flower farms, exporting blooms all over the world. Once owned by a member of the Happy Valley set, the estate was first established as a cattle ranch until a Dutch entrepreneur Hans Zwager acquired the estate in 1968 and started exploring opportunities in agribusiness with a small ...

Postharvest technologies for extending the shelf life of ornamental crops
1-Methylcyclopropene (1-MCP) and other cyclopropenes block ethylene responses in plants at the receptor level. 1-MCP is commercially available under the trade name of EthylBloc® and SmartFresh™. It is very effective in blocking ethylene responses in a range of ornamental crops, fruits and vegetables. Some recently prepared 1-substituted cyclopropenes inactivate the receptor even for a longer time ...

What is the right light intensity and illumination length?
Photoperiodism The photoperiod, this is used as a signal for the plant to flower. Many flowering plants (angiosperms) use a photoreceptor protein, such as phytochromeor cryptochrome, to sense seasonal changes in night length, The Phytochrome conversion (Pfr to Pr) allows the plant to sense when it is night or day. Phytochrome Conversion The biologically-inactive form of ...

Influence of root exudates of watermelon on fusarium oxysporum f. Sp. Niveum
Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus] production in the same field without rotation of crops leads to disease buildup and poor yields. The purpose of this research was to evaluate the influences of root exudates produced by watermelon cultivars susceptible or resistant to the pathogen Fusarium oxysporum f. sp. niveum (FON). At low concentrations of root exudates ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...

Agrochemicals in field margins—assessing the impacts of herbicides, insecticides, and fertilizer on the common buttercup (Ranunculus acris)
The effects of herbicide, insecticide, and fertilizer inputs on the common buttercup Ranunculus acris in field margins were studied in an experimental field study. The test design allowed us to investigate the single and combined effects of repeated herbicide, insecticide, and fertilizer applications in successive growing seasons. To assess the effects of the agrochemical applications on R. ...

Microbial characterisation of vermicompost and compost of urban waste processed by three earthworm species - Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
Species diversity of bacteria, fungi and actinomyctes of vermicompost and compost of the organic fraction of municipal solid waste, vegetable market waste and flower waste were assessed using pour plate technique. Of the total 91 entities, 62 were bacteria and 29 were actinomycetes in MW, followed by that of MSW and FW, with 59 and 55 bacterial; 25 and 22 actinomycetes entities, respectively. The ...

Ploidy determination and agronomic characterization of small burnet germplasm
Small burnet (Sanguisorba minor Scop.) is an evergreen forb readily utilized by livestock and wildlife that lacks persistence under heavy grazing. Our objective was to characterize all available National Plant Germplasm System (NPGS) small burnet germplasm for ploidy level and agronomic characteristics before initiating a breeding program. Ploidy level was determined by flow cytometry. Forage ...

Predicting outcrossing in maize hybrid seed production
Controlling pollination of the female inbred is critical to achieve maximum kernel set and high levels of genetic purity in maize (Zea mays L.) hybrid seed production. Although kernel set associated with inbred flowering dynamics is fairly predictable, it has not been possible to predict the level of outcrossing resulting from adventitious pollen entering the seed field. Our objective was to ...
