The Effects Of Potassium Fertilization Regime On High Tunnel Tomato Production, Sapana Pandey

Theses and Dissertations--Plant and Soil Sciences

A two-year field experiment (2022-2023) was conducted at the University of Kentucky Horticulture Research Farm in Lexington, KY to study the effects of potassium (K2O) fertilization rates on tomato yield and ripening disorders in determinate and indeterminate varieties (‘BHN-589’ and ‘Big Beef’, respectively). In the first year, K2O rates representing the soil test result-based commercial recommendation (0 lbs/acre) and sequentially greater rates (150, 300, and 450 lbs K2O/acre) were applied. In the second year, K2O rates were increased based on lack of fruit quality response and were 0, 300, 600, and 900 lbs K2O/acre. Leaf tissue nutrients, tomato yield, and …

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2023, Petrus Langenhoven, Dennis Gustavo Toc Mo

Midwest Vegetable Trial Reports

Colored sweet bell-shaped and tapered pepper is a summer crop that is grown by many small and medium-sized farming operations in Indiana. Growers can choose to grow peppers out in the field or plant them under a protective structure. Sweet peppers, in particular, benefit from the unique growing environment created by a high tunnel. Planting of peppers can start at least 2-4 weeks earlier in the spring, and production can continue into the fall until the first hard freeze. Pepper variety performance data for Indiana is not readily available. We are working hard to change that. To date, we have …

Research Report: High Tunnel Tomato Fruit Cluster Pruning, Caterina Roman, Rebecca G. Sideman

Faculty Publications

Tomatoes are a high value crop grown worldwide. Indeterminate varieties are commonly grown in high tunnel structures throughout New England for the fresh market. Indeterminate tomato plants often suffer from a phenomenon called ‘June drop’ in which the plant’s first four to five cluster of fruit set perfectly but the subsequent two to three clusters have poor set and plant productivity drops suddenly. While cluster thinning (e.g., reducing the number of fruit allowed to mature per cluster) has been successfully shown to increase fruit size, it has generally not increased marketable yield. We hypothesized that reducing the fruit load by …

High Tunnel Pest Management - Caterpillars, Nick Volesky, Marion Murray

All Current Publications

In Utah high tunnel production, there are various caterpillar pests (larvae of moth and butterfly species) that cause economic damage to crops. Common caterpillar pest species found in Utah include hornworms, tomato fruit worms, imported cabbage worms, diamondback moths, cabbage loopers, armyworms, and cutworms. Various weed species growing inside or outside high tunnels can attract and harbor caterpillar pests. Managing caterpillar pests in high tunnels involves various mechanical, chemical, biological, and cultural control practices.

Evaluation Of ‘Mortgage Lifter’ Tomato For High Tunnel Production, Lewis Jett

Midwest Vegetable Trial Reports

The ‘Mortgage Lifter’ tomato has historical roots in West Virginia and central Appalachia. The strain which is most often associated with West Virginia is the ‘Radiator Charlie Mortgage Lifter’ which is a red to pink beefsteak slicing tomato (Figure 1). In 2018, several heritage tomato varieties were evaluated within high tunnels in West Virginia. High Tunnels significantly improved yield and quality of all varieties, and ‘Mortgage Lifter’ had marketable yields comparable to hybrid tomato cultivars. Wholesale marketing high tunnel tomatoes is usually not profitable but concentrating on unique, heritage varieties with high flavor for direct marketing is the best strategy …

Manipulating Air And Root-Zone Temperature For Energy-Efficient Floriculture Crop Production, Madeline W. Olberg

Open Access Theses

Given the high energy costs for greenhouse floriculture production, growers are constantly searching for more energy-efficient methods of production. For example, some growers will lower greenhouse air temperature set points or grow crops in unheated high tunnels (HTs) or outdoors in order to minimize or eliminate heating costs. Unfortunately, development can be delayed and morphology can be altered if the mean daily air temperature (MDT) is reduced. We proposed that reducing MDT in combination with root-zone heating (RZH) could be an energy-efficient method for producing high-quality floriculture crops without significant delays. Unheated HT and unprotected outdoor production are very low-cost …

An Ipm Scouting Guide For Common Problems Of High Tunnel And Greenhouse Vegetable Crops In Kentucky, Shubin Saha, Emily Pfeufer, Ricardo Bessin, Shawn Wright, Cheryl A. Kaiser

Agriculture and Natural Resources Publications

Long before the term “sustainable” became a household word, farmers were implementing sustainable practices in the form of Integrated Pest Management (IPM) strategies. IPM uses a combination of biological, cultural, physical, and chemical methods to reduce and/or manage pest populations. These strategies are used to minimize environmental risks, economic costs, and health hazards. Pests are managed (although rarely eliminated) to reduce their negative impact on the crop.

Scouting and monitoring diseases, insects, weeds, and abiotic disorders in order to identify potential problems before they result in serious losses is essential to the IPM approach. The key to effective monitoring is …
