High Tunnel Broccoli Cultivar Evaluations, Lewis Jett Jan 2024

High Tunnel Broccoli Cultivar Evaluations, Lewis Jett

Midwest Vegetable Trial Reports

Broccoli is a potentially profitable crop for high tunnel production. Updated information on yield and quality of new cultivars is important for producers making planting decisions. This evaluation of 11 cultivars was conducted within a high tunnel in Fall 2023.


Evaluation Of 11 Broccoli Cultivars For Summer Harvest In Southwest Michigan In 2023, Ben Phillips, Leah Freeman Dec 2023

Evaluation Of 11 Broccoli Cultivars For Summer Harvest In Southwest Michigan In 2023, Ben Phillips, Leah Freeman

Midwest Vegetable Trial Reports

A broccoli cultivar trial was planted at the Southwest Michigan Research and Extension Center (42.081985, -86.354087, Benton Harbor, Michigan). Bejo (BJ), Clifton (CL), Sakata (SK), and Tozer (TZ) seed companies donated 11 broccoli cultivars for plastic-mulch bedded hand harvest. The trial quality was good for collecting data on stressed plants. A dry start and cabbage maggot attack reduced stand with replacement plants lagging behind, and heat around head formation created a high proportion of non-marketable heads.


Biobased Sprayable Mulch Films Suppressed Annual Weeds In Vegetable Crops, Eliott Gloeb, Sibel Irmak, Loren Isom, John L. Lindquist, Samuel E. Wortman Dec 2022

Biobased Sprayable Mulch Films Suppressed Annual Weeds In Vegetable Crops, Eliott Gloeb, Sibel Irmak, Loren Isom, John L. Lindquist, Samuel E. Wortman

Department of Agronomy and Horticulture: Faculty Publications

Biobased sprayable mulch (BSM) films are a potential alternative to herbicides, polyethylene plastic mulch film, and hand weeding for specialty crops. We developed a series of BSM films using locally available biomaterials [including corn (Zea mays) starch, glycerol, keratin hydrolysate, corn gluten meal, corn zein, eggshells, and isolated soy (Glycine max) protein] and tested their effects on weeds and crop yield during a total of seven greenhouse or field trials between 2017 and 2019 in Nebraska, USA. Application rates of BSM films applied in pots (greenhouse), planting holes in plastic film (field), or bed tops (field) …


Abrasive Weeding As A Vehicle For Precision Fertilizer Management In Organic Vegetable Production, Tran Kim Ngan Luong, Frank Forcella, Sharon A. Clay, Michael S. Douglass, Sam E. Wortman Feb 2021

Abrasive Weeding As A Vehicle For Precision Fertilizer Management In Organic Vegetable Production, Tran Kim Ngan Luong, Frank Forcella, Sharon A. Clay, Michael S. Douglass, Sam E. Wortman

Agronomy, Horticulture and Plant Science Faculty Publications

Abrasive weeding is a nonchemical weed control tactic that uses small, gritty materials propelled with compressed air to destroy weed seedlings. Organic fertilizers have been used successfully as abrasive grits to control weeds, but the goal for this study was to explore the effects of fertilizer grit, application rates, and background soil fertility on weeds, plant available nitrogen (N) uptake, and crop yield. Field trials were conducted in organic ‘Carmen’ sweet red pepper (Capsicum annuum) and organic ‘Gypsy’ broccoli (Brassica oleracea var. italica) and treatments included organic fertilizer grit (8N–0.9P–3.3K vs. 3N–3.1P–3.3K), grit application rates (low …

Fall Broccoli Production In High Tunnels, Wenjing Guan Jan 2020

Fall Broccoli Production In High Tunnels, Wenjing Guan

Midwest Vegetable Trial Reports

A fall broccoli trial was conducted in a high tunnel at the Southwest Purdue Agricultural Center, Vincennes, IN in 2016 to test the potential of growing broccoli in high tunnels after tomato. Six broccoli cultivars were evaluated in the trial. Seedlings were transplanted in the high tunnel on Sep. 2. Plants started to form heads in the middle of October. The first harvest occurred on Oct. 25 on cultivars Blue Wind and Green Magic. Harvest for cultivars Belstar and Arcadia started the latest on Nov. 11. Cultivars Green Magic and Blue Wind developed about 2 side heads per plant, which …


A Study Of Short-Season Winter Cover Crops For Organic High Tunnel Production Systems, Luke Riley Freeman Dec 2016

A Study Of Short-Season Winter Cover Crops For Organic High Tunnel Production Systems, Luke Riley Freeman

Graduate Theses and Dissertations

This two-year study investigated short-season winter cover crops to improve soil quality and growth of subsequent vegetable crops in an organic high tunnel production system. Five winter cover crop treatments including a nontreated control, Austrian winter peas (Pisum arvense), bell beans (Vicia faba), mustard (Brassica juncea cv. Kodiak), and Daikon radish (Raphanus sativus var. longipinnatus) were grown in a high tunnel in a randomized complete block design from mid-November to mid-March, mowed and incorporated into the soil, and followed by a succession of vegetable crops including tomato (Lycopersicon lycopersicum, cv. ‘Plum Dandy’) and broccoli (Brassica oleracea var. italica, cv. ‘Bay …
