2021 Midwest Broccoli Trial Results
(2021-12-17) Hoidal, Natalie, M; Rohwer, Charlie; Enjalbert, Nicolas
We conducted a replicated broccoli trial at the Southern Research and Outreach Center (SROC) in Waseca, Minnesota, where we inoculated plots with black rot (Xanthamonas campestris pv. campestris). We also partnered with 80 farmers and gardeners to conduct mini trials at their farms. (Figure 1). Our goal was to screen for varieties of broccoli with tolerance to the pathogens black rot (Xcc) and Alternaria (Alternaria brassicicola). This report outlines preliminary results from the trials. Due to the hot, dry summer in the Midwest, disease pressure was minimal, particularly in the early planting.

Based on the needs assessment and retreat, we have identified priority areas for fruit and vegetable research and education with Minnesota farmers.
Nutrient management for fruit and vegetable crop production: Using manure and compost as nutrient sources for vegetable crops
(2005) Rosen, Carl J.; Bierman, Peter M.
Manure and compost not only supply many nutrients for crop production, but they are also valuable sources of organic matter. Increasing soil organic matter improves soil structure, increases the water-holding capacity of coarse-textured sandy soils, improves drainage in fine-textured clay soils, provides a source of slow release nutrients, reduces wind and water erosion, and promotes growth of earthworms and other beneficial soil organisms. Most vegetable crops return small amounts of crop residue to the soil, so manure, compost, and other organic amendments help maintain soil organic matter levels. This discussion addresses differences between the composition of fresh and composted manure, nutrient availability from manure and compost, and calculation of how much manure or compost to apply. Although focused on manure or composted manure, much of the discussion and the methods for calculating rates are generally applicable to effective use of different types of compost, biosolids, and similar organic nutrient sources.
Fertilizing Lawns
(2008) Rosen, Carl J.; Horgan, Brian P.; Mugaas, Robert J.
Healthy lawns depend on many factors including adequate water for cell enlargement and evaporative cooling, sunlight and carbon dioxide for energy production, and oxygen for respiration. Lawn growth also depends on nutrients or essential elements absorbed by roots from the soil. When natural soil processes do not provide adequate supplies of these essential elements, fertilizer can be applied to maintain optimum turfgrass growth. The purpose of fertilizing a lawn is to add the necessary nutrients in the required amounts and at the proper time to achieve desirable lawn qualities and healthy turfgrass plants. This publication will help to develop a fertilizer program to promote a healthy lawn.
Protecting trees from construction damage: a homeowner's guide
(1999) Johnson, Gary R.
Trees and shrubs contribute to property values by enhancing appearance, reducing noise, cutting energy costs, screening unsightly views, and attracting songbirds and other wildlife. Unfortunately, plants meant to be part of a home's permanent landscape often are needlessly damaged or killed during construction. Careful planning and coordination with a tree-care specialist and your builder can reduce damage and save you the trouble and expense of treating or removing injured plants. This publication explains some things that landowners can do to minimize the impact of construction on trees. It describes landscape protection plans, special construction techniques, symptoms of damage, and treatment strategies. Although the information presented focuses on trees, it also can be applied to protecting shrubs.
Growing garlic in Minnesota
(2016) Rosen, Carl; Becker, Roger; Fritz, Vincent A.; Hutchinson, Bill; Percich, Jim; Tong, Cindy; Wright, Jerry
Garlic (Allium sativum L.), a member of the onion family, has been cultivated for thousands of years and is widely used for both its culinary and medicinal attributes. As Americans have become more accustomed to garlic flavor and knowledgeable about the many health benefits of eating garlic, popularity of this crop has increased. Most garlic in the U.S. is grown in the mild climate of northern California. Varieties adapted to mild climates and then grown in cold climates often do not perform well and usually develop a very "hot" flavor. Garlic is an adaptable species, however, and varieties have been selected that grow well in cold climates, often with better garlic flavor than the varieties grown in mild climates. This publication provides guidelines for growing garlic in cold climates. The major areas addressed include variety selection, soils, cultural practices, pest management, harvesting, and storage.
Pest management for the home apple orchard
(2011) Hahn, Jeffrey D.; Grabowski, Michelle; MacKenzie, Jill
Minnesotans who grow apples at home have to combat many insect pests and diseases to produce a good crop. Many apple growers reduce their use of pesticides, while still harvesting quality fruit, through a set of practices known as Integrated Pest Management (IPM). IPM includes a combination of pest management techniques including monitoring for pest problems, removing diseased or infested plant material from the area, and many other cultural control techniques. Pesticide sprays are used in IPM only when necessary, and gardeners may choose from conventional or organic spray options.
Pest management for the home stone fruit orchard
(2015) University of Minnesota
A surprising variety of apricots, plums and tart cherries can be grown in Minnesota. Although insect and disease pressure is lower here than in states to the south or east, there are insects and diseases that can destroy fruit and harm trees. Pest problems are best dealt with through the practice of Integrated Pest Management (IPM). IPM is a sustainable approach that allows gardeners to reduce pests to a tolerable level by using the best balance of cultural, physical, biological, & chemical management strategies. IPM takes into account the level of damage a pest is capable of causing, as well as the possible risks to humans and the environment associated with each pest management strategy.
Pest management for the home strawberry patch
(2015) Foord, Karl; Hahn, Jeffrey D.; Grabowski, Michelle
Minnesotans who grow strawberries at home may have to combat insect pests or diseases to produce a good crop. Previous pest control strategies seeking to eliminate all pests from a garden have been shown to be unsuccessful. Today's approach combines many management methods into an integrated whole, thus the name Integrated Pest Management (IPM). IPM practices have enabled growers to place an emphasis on non-chemical methods while using pesticides secondarily or as a supplement to these methods while still harvesting quality fruit. The philosophy of IPM is to seek a balance maximizing yield while reducing human and environmental risk. This follows a particular hierarchy that begins with the best practices in cultural management.
Pest management for the home raspberry patch
(2015) University of Minnesota
For home gardeners, raspberries are one of the easiest fruits to grow. Raspberries grown in Minnesota have relatively few insect pests and diseases. Gardeners who use Integrated Pest Management (IPM) practices often have good yields every year without applying pesticides. IPM is a sustainable approach that allows gardeners to reduce pests to a tolerable level by using the best balance of cultural, physical, biological, & chemical management strategies. IPM takes into account the level of damage a pest is capable of causing, as well as the possible risks to humans and the environment associated with each pest management strategy.
Pest management for home blueberry plants
(2015) University of Minnesota
Blueberries grown in Minnesota have few serious insect pests and diseases. Gardeners who use Integrated Pest Management (IPM) practices may never have a need to apply pesticides to their plants. IPM is a sustainable approach that allows gardeners to reduce pests to a tolerable level by using the best balance of cultural, physical, biological, & chemical management strategies. IPM takes into account the level of damage a pest is capable of causing, as well as the possible risks to humans and the environment associated with each pest management strategy.
Asparagus production guide
(2013) Fritz, Vincent A.; Rosen, Carl J.; Hutchinson, William D.; Becker, Roger L.; Beckerman, Janna; Wright, Jerry A.; Tong, Cindy B. S.; Nennich, Terry
Asparagus is a high value specialty crop and the earliest producing spring vegetable. It currently is priced as a gourmet item and will remain in this category until growing, harvesting, and processing costs can be reduced. Although production in the United States is concentrated in California, Washington, and Michigan, many other areas have great production potential climatically and geographically. The cost to establish an asparagus field is substantial, so the decision to grow asparagus is one that should be thoroughly investigated. This publication describes the cultural practices that must be considered to produce asparagus successfully.
Nutrient management for fruit and vegetable crop production: Nutrient cycling and maintaining soil fertility
(University of Minnesota Extension Service, 2005) Bierman, Peter M; Rosen, Carl J
The focus of this bulletin is on biology, placing nutrient cycling at the center of nutrient management, but the biological emphasis is not meant to disregard other factors. The objectives are to examine and illustrate: Biological, chemical, and physical processes plant nutrients go through as they cycle through the soil; How these processes affect nutrient availability to plants and nutrient movement from farm fields to surface or groundwater; Ways to manage crops and soils to maximize nutrient availability and minimize nutrient movement to the surrounding environment. Understanding processes helps identify practical options that fit different farming systems. Understanding nutrient cycles helps all types of farmers maintain the fertility of their soils, while at the same time protecting our water resources.
