Testing A Warning System For Anthracnose Fruit Rot On Day-Neutral Strawberry—Year 3, Xiaoyu Zhang, Jean C. Batzer, Mark L. Gleason 2014 Iowa State University

Testing A Warning System For Anthracnose Fruit Rot On Day-Neutral Strawberry—Year 3, Xiaoyu Zhang, Jean C. Batzer, Mark L. Gleason

Iowa State Research Farm Progress Reports

Anthracnose fruit rot (AFR) of strawberry is caused by three Colletotrichum spp. In the Midwest, however, only Colletotrichum acutatum is found. This fungus can attach itself to apparently healthy plants and spread throughout the field without causing symptoms on the foliage. When fruit begins to ripen and weather conditions are rainy and warm, AFR can suddenly cause great damage to the fruit. To protect against AFR where it has appeared in the past, growers need to spray every 7 to 10 days beginning at the start of bloom until harvest.

Colored Plastic Mulches For High Tunnel Tomato Production, Ajay Nair, Bernard J. Havlovic

Iowa State Research Farm Progress Reports

Weather often is one of the limiting factors for crop production in northern states. Growers in Iowa and other northern climatic regions are increasingly utilizing high tunnels to extend their growing season and increase fruit and vegetable production. In early spring and late fall, high tunnels help warm the air and soil and aid with crop growth and development. However, during summer, temperatures rise quickly in high tunnels and can detrimentally affect crop growth and development.

The Influence Of Organically Managed High Tunnel And Open Field Production Systems On Strawberry (Fragaria X Ananassa) Quality And Yield, Tomato (Solanum Lycopersicum) Yield, And Evaluation Of Plastic Mulch Alternatives, Jeffrey Thomas Martin

Masters Theses

High tunnels extend the production season, and increase fruit quality, yield and crop marketability of high-value crops, but have been underutilized in the Southeast. In this study, organically managed variety trials of two high-value crops, strawberry (Fragaria x ananassa) and tomato (Solanum lycopersicum), were conducted in high tunnel (HT) and open field (OF) production systems to compare yield and quality. Furthermore, specialty crops are commonly grown on black plastic mulch to increase earliness of harvest, fruit quality and yield. However, plastic disposal is time consuming and costly. Degradable mulches reduce removal costs, lessen environmental impacts, and provide functionality during the ...

The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination ...


Canopy Management Practices And Light Interception Of Northern Grape Cultivars, Dylan P. Rolfes, Gail R. Nonnecke, Paul A. Domoto 2013 Iowa State University

Canopy Management Practices And Light Interception Of Northern Grape Cultivars, Dylan P. Rolfes, Gail R. Nonnecke, Paul A. Domoto

Iowa State Research Farm Progress Reports

The recent development of Vitisriparia hybrids has allowed the expansion of the wine industry into Iowa and the Upper Midwest. These cultivars are more cold hardy and vigorous than traditional V. vinifera hybrids. During maturation the fruit tend to retain high levels of acids, exhibit a rapid rise in pH, accumulate high potassium levels, and possess a different profile of malic to tartaric acid than other hybrids. Wines from these grapes often have a “grassy” or “herbaceous” flavor. These same characteristics have been associated with fruit grown in shaded canopies. This study was undertaken as part of the USDA Northern ...

Effects Of Temperature And Light In High Tunnel Primocane Red Raspberry Production, Leah B. Riesselman, Gail R. Nonnecke 2013 Iowa State University

Effects Of Temperature And Light In High Tunnel Primocane Red Raspberry Production, Leah B. Riesselman, Gail R. Nonnecke

Iowa State Research Farm Progress Reports

High tunnel production of primocane red raspberries extendsthe growing season, decreases winter injury, increases cane height and growth rate, and improves overall fruit quality and yield. However, tunnels have the potential to increase light intensity levels and result in high air and soil temperatures, which are detrimental to primocane red raspberry production. Soil and air temperatures above 16°C (60.8°F) and 24°C (75.2°F) and light intensity levels beyond 600 µmol·mˉ²sˉ¹ have been shown to decrease water uptake, encourage premature bud-dormancy, delay time to ripening, and reduce fruit quality and weight. The proposed study is ...
