Strip-Tillage And Row Cover Use In Organically And Conventionally Grown Muskmelon, Jennifer L. Tillman, Ajay Nair, Jean C. Batzer, Mark L. Gleason Jan 2014

Strip-Tillage And Row Cover Use In Organically And Conventionally Grown Muskmelon, Jennifer L. Tillman, Ajay Nair, Jean C. Batzer, Mark L. Gleason

Iowa State Research Farm Progress Reports

Growing muskmelon in a more sustainable way involves multiple management practices. Cover crops often are incorporated into the soil before planting the cash crop. However, they also can be “rolled” and used as a ground cover throughout the growing season. The cash crop is planted in small, tilled strips within the residue. This “strip-tillage” technique provides a weed-controlling, moisture-retaining mat that does not need to be removed at the season’s end, as plastic mulch does. The reduction in tillage can improve soil structure and health.

Here, we report on above- and below-ground biomass production from selected treatments.


Long-Term Tillage And Crop Rotation Effects On Soil Carbon And Soil Productivity, Mahdi Al-Kaisi, David Kwaw-Mensah Jan 2014

Long-Term Tillage And Crop Rotation Effects On Soil Carbon And Soil Productivity, Mahdi Al-Kaisi, David Kwaw-Mensah

Iowa State Research Farm Progress Reports

Tillage system and crop rotation have major long-term effects on soil productivity and soil quality components of soil carbon and other soil physical, biological, and chemical properties. Additionally, tillage systems and crop rotation controls weed and soil borne diseases. There is a need for a well-defined, long-term tillage and crop rotation study across the different soil types and climate conditions in the state. The objective of this study was to evaluate the long-term effects of different tillage systems and crop rotations on soil quality and productivity.

Growth Performance And Ultrasonic Scan Of Purebred Berkshire Pigs Housed In Hoop Buildings In Iowa (Trials 3 And 4), P. Matthew Swantek, David R. Stender, John W. Mabry, Mark S. Honeyman, Wayne B. Roush Jan 2014

Growth Performance And Ultrasonic Scan Of Purebred Berkshire Pigs Housed In Hoop Buildings In Iowa (Trials 3 And 4), P. Matthew Swantek, David R. Stender, John W. Mabry, Mark S. Honeyman, Wayne B. Roush

Iowa State Research Farm Progress Reports

A certified Berkshire program continues to lead niche pork production markets based on its meat quality advantage over commodity-based pork. This economic advantage is especially valuable for smaller, more traditional pork producers. The disadvantages of Berkshire pigs are fatter carcasses, slower gains, and less efficient feed conversion compared with commodity pork production. Consequently, these pigs are often a better fit for less intensive or lower production systems.

Comparison Of Ivermectin And Extended-Release Eprinomectin Deworming Treatment On Stocker And Subsequent Feedlot Performance And Carcass Characteristics Of Fall-Born Angus Heifers, Christopher A. Clark, Patrick J. Gunn, Joe Dedrickson, Jerry Sorenson Jan 2014

Comparison Of Ivermectin And Extended-Release Eprinomectin Deworming Treatment On Stocker And Subsequent Feedlot Performance And Carcass Characteristics Of Fall-Born Angus Heifers, Christopher A. Clark, Patrick J. Gunn, Joe Dedrickson, Jerry Sorenson

Iowa State Research Farm Progress Reports

Severe parasite infections in beef cattle are sometimes associated with decreased growth and performance and clinical disease. Stocker cattle are exposed to many parasites and appropriate deworming strategies can help to minimize parasite burdens when cattle are on grass. Feedlot cattle are often dewormed at arrival and have minimal exposure to additional parasites once placed in the feedlot. The purpose of this study was to evaluate stocker and feedlot performance and carcass characteristics relative to treatment with deworming agents of varying durations of activity.

Attracting Beneficial Insects To Iowa Agricultural Crops Through Floral Provisioning, Thelma T. Heidel-Baker, Matthew E. O'Neal, Jean C. Batzer, Mark L. Gleason Jan 2014

Attracting Beneficial Insects To Iowa Agricultural Crops Through Floral Provisioning, Thelma T. Heidel-Baker, Matthew E. O'Neal, Jean C. Batzer, Mark L. Gleason

Iowa State Research Farm Progress Reports

Beneficial insects can provide valuable ecosystem services such as pest control and pollination for agricultural crops, but agricultural crops often provide limited food and refuge resources necessary to these beneficial insects. Planting flowers can provide some of these limited resources such as nectar, pollen, and refuge. Floral provisioning could enhance the beneficial insect community in agricultural crops if flowers are placed adjacent to the crops. This research project explores whether floral provisioning can increase the ecosystem services provided by pollinating and predatory insects in agricultural crops.

Effects Of Row Cover Removal Timing In Organic Muskmelon, Zachary Torres, Jean C. Batzer, Mark L. Gleason Jan 2014

Effects Of Row Cover Removal Timing In Organic Muskmelon, Zachary Torres, Jean C. Batzer, Mark L. Gleason

Iowa State Research Farm Progress Reports

Muskmelons are difficult to grow using organic practices because of bacterial wilt and the cucumber beetle that vectors the disease. Row covers can be placed over muskmelon transplants and then removed at anthesis (the period at which 50% of plants have female flowers). In addition to shielding muskmelons from bacterial wilt, row covers also can protect plants from early season frost, wind damage, and fungal diseases. However, the intensive labor needs of row-cover deployment have limited their use to small fields on small-scale farms

Seasonal And Rotational Influences On Corn Nitrogen Requirements, John E. Sawyer, Daniel W. Barker Jan 2014

Seasonal And Rotational Influences On Corn Nitrogen Requirements, John E. Sawyer, Daniel W. Barker

Iowa State Research Farm Progress Reports

This project was designed to study the N fertilization needs in continuous corn (CC) and corn rotated with soybean (SC) as influenced by location and climate. Multiple rates of fertilizer N were spring applied, with the intent to measure yield response to N within each rotation on a yearly basis for multiple years at multiple sites across Iowa. This will allow the determination of N requirements for each rotation, differences that exist between the two rotations, responses to applied N across different soils and climatic conditions, and evaluation of tools used to adjust N application.

National Elm Trial, Jean C. Batzer, Mark L. Gleason

Iowa State Research Farm Progress Reports

Although many Dutch elm disease-resistant elm cultivars are available in the nursery trade, much of the public is hesitant to purchase and plant any elm tree. In order to promote interest in planting these trees, scientific data on growth, form, and pest resistance for existing Dutch elm disease resistant elm cultivars are essential.


Summer Cover Crop Influence On Fall Vegetable Production, Raymond A. Kruse, Ajay Nair Jan 2014

Summer Cover Crop Influence On Fall Vegetable Production, Raymond A. Kruse, Ajay Nair

Iowa State Research Farm Progress Reports

At the 2012 Fruit and Vegetable Field Day held at the Iowa State University Horticulture Farm, Ames, Iowa, one of the major challenges highlighted by commercial vegetable growers was “weed management.” Growers called for research on sustainable and environmentally conscious (less herbicide) ways of weed management. Use of cover crops to suppress weeds was one of the outcomes of the discussion. The goal of this project was to evaluate and study what advantages exist under Iowa growing conditions for four cover crops to satisfy farmer’s goals. The four cover crops studied were: Buckwheat (cool season broadleaf), Cowpea (warm season ...
