Quantifying How High Tunnels Create a Microclimate For Improved Crop Growth
… in inexpensive low-tech greenhouses, known as high tunnels (HTs) or hoop houses. This study evaluated the microclimate inside HTs, how farmers were using HTs to grow crops and how the microclimate inside HTs led to improved crop growth. The HT microclimate varied by season, with more growing …

Assessing the conservation value and food system impacts of high tunnels
… sold locally, but climate often limits supply. High tunnels can often overcome these limitations. In order to encourage local availability and production of specialty crops the Natural Resource Conservation Service (NRCS) has launched the Seasonal High Tunnel initiative. This cost-share program …

Effects of plastic mulch, row cover, and cultivar selection on growth of tomatoes (Lycopersicon esculerntum Mill.) in high tunnels
… among different cultivars when grown in high tunnels. Row covers did not significantly increase total, or US number 1 yield of high tunnel tomatoes. Clear plastic mulch significantly increases early yield of grade 1 fruit over all other treatments. Total early yields from BHN 543, and …

Fruit cluster pruning impacts on yield and quality of three tomato cultivars in an organic high tunnel system
The successful production of high-quality, high-yielding crops is important for fruit and vegetable producers, especially growers who use high tunnels. The valuable space within a high tunnel is well-suited to organic farming and can be used to grow many specialty crops. Fruit load management is …

Epidemiological studies and sustainable approaches for the control of strawberry powdery mildew
… the spatiotemporal dispersal of the disease in high tunnels; (iv) to quantify the role of overwintering inoculum and evaluate post-winter leaf removal for the control of early-season primary infection; and (v) to develop a management strategy by limiting synthetic fungicides to early-season …

Soil quality and nitrogen cycling dynamics altered by fertility amendments in intensively managed vegetable production systems
… of increased demand for locally-sourced food. High tunnels are becoming increasingly popular among Midwest vegetable growers as these structures offer many production benefits including season extension. However, vegetables require substantial fertility inputs, particularly nitrogen (N), in …

Spotted-wing Drosophila: Investigating the Efficacy of Innovative and Alternative Management Techniques
… result in widespread infestation likely due to high SWD populations, immigration by new individuals, and/or inadequate spray penetration in the dense plant canopy. Frequent applications of broad spectrum insecticides continues to be the most prevalent management strategy, but pesticide …
