Mass Loss And Chemical Structures Of Wheat And Maize Straws In Response To Ultravoilet-B Radiation And Soil Contact, Guixiang Zhou, Jiabao Zhang, Jingdong Mao, Congzhi Zhang, Lin Chen, Xiuli Xin, Bingzi Zhao

Chemistry & Biochemistry Faculty Publications

The role of photodegradation, an abiotic process, has been largely overlooked during straw decomposition in mesic ecosystems. We investigated the mass loss and chemical structures of straw decomposition in response to elevated UV-B radiation with or without soil contact over a 12-month litterbag experiment. Wheat and maize straw samples with and without soil contact were exposed to three radiation levels: a no-sunlight control, ambient solar UV-B, and artificially elevated UV-B radiation. A block control with soil contact was not included. Compared with the no-sunlight control, UV-B radiation increased the mass loss by 14-19% and the ambient radiation by 9-16% for …

An Economic Analysis Of High-Intensity, Short-Duration Grazing Systems In South Dakota And Nebraska, Larry Janssen, Bronc Mcmurtry, Matthew Stockton, Alexander Smart, Sharon A. Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Four different grazing systems: two rotational systems, a continuous grazing system, and a modified high-intensity, short-duration (mob) system were evaluated from an economic return and risk perspective. Stocking rates and average daily gains (ADG) were obtained from 2011 – 2014 from university ranch experiments in northern Nebraska. Simulation models were used to examine net returns and risk in each system and rank systems according to risk preferences. A twice through rotational grazing system was most profitable. Mob grazing was the least preferred, although when risk aversion increased, it rose in preference. Mob grazing could be profitable if adjustments increased animal …

Nutrient Availability And Dynamics Of Compost Bedded Pack Dairy Barn Waste, Leslie Hammond

Theses and Dissertations--Plant and Soil Sciences

Increased adoption of compost bedded pack dairy barns (CBP), a relatively new housing and manure handling strategy, warrants study to facilitate proper use of CBP waste as a soil amendment. This study: 1) characterized in situ nutrient content and availability of CBP waste in terms of nitrogen (N) and phosphorus (P); 2) examined the decomposition of surface-applied CBP waste compared to an alternative processed solid waste amendment; 3) examined nutrient dynamics of incorporated CBP waste in high and low soil test phosphorus (STP) environments. Quick anaerobic mineralization assays revealed that bed management affects nutrient content and availability of CBP waste. …

Factors Influencing Sustainable Cocoa Production In Northern Haiti, Wegbert Chery

LSU Master's Theses

Given the environmental concerns on the one hand, especially soil erosion and deforestation, and the hope that the global cocoa market offers on the other hand, cocoa production is a potential candidate to simultaneously guarantee a competitive return to investment for farmers in northern Haiti and mitigate the negative environmental impact of farming practices. It becomes crucial for policy makers and investors to know and understand the key elements of the decision to produce cocoa. Though there has been substantial effort to improve the cocoa sector in Haiti, cocoa production systems in Haiti lag behind in the area of sustainability. …

Evaluation Of The Impact Of Changes In Commodity Income Support Measures Included In The Agricultural Act Of 2014 On Equitable Louisiana Rice Production Rental Arrangements, Abdallahi Ould Abderrahmane

LSU Master's Theses

ABSTRACT This research uses a Simetar simulation technique to evaluate the effect of the adoption of the Price Loss Coverage program included in the 2014 Agricultural Act on Louisiana’s rice equitable rental arrangement choices. Two scenarios are examined: one in which prices of the last three years are detrended and a second one in which they are not detrended. Each scenario includes six rental arrangements (Cash rent, Fixed Price, Fixed Yield, 60/40, 70/30, 80/20) and each rental arrangement has four adjustments (base, price trigger, yield trigger, and price and yield trigger). Three different risk measure analysis were conducted: Mean-Variance, Value …

Supersweet Sweet Corn Cultivar Evaluation For Northern Indiana, 2014, Elizabeth Maynard

Purdue Fruit and Vegetable Research Reports

Indiana sweet corn acreage harvested for fresh market averaged 5,233 acres annually from 2011- 2013, with a yield of 63 hundreweight per acre (149 crates or 3.1 tons per acre) and an annual value of $13.9 million (USDA NASS, 2014). Sweet corn fields for fresh market sales are located throughout the state. In northern Indiana, bicolor corn is most commonly grown.

Varieties with improved eating quality are of interest to both producers and consumers. The term ‘supersweet’ commonly refers to sweet corn with two copies of the shrunken-2 (sh2) gene that have high levels of sugar in the kernels and …

Midwest Cantaloupe Variety Trial In Southwest Indiana — 2014, Dan Egel, Dennis Nowaskie, Sara Hoke

Purdue Fruit and Vegetable Research Reports

This is a compilation of 30 research trial reports from four land-grant universities in the Midwestern United States. Crops include cantaloupe, pickling cucumber, pepper, potato, pumpkin, summer squash and zucchini, sweet corn, tomato, and watermelon. Somecrops were evaluated in high tunnels or hoophouses. Most trials evaluated different cultivars or varieties. One report addressed plant spacing for sweet corn and one addressed soil block for production of tomato seedlings. A list of vegetable seed sources and a list of other online sources of vegetable trial reports are also included.

Growing Community Gardens Through Education, Kaitlyn Becka, Sydney Martis, Rich Mehok

Williams Honors College, Honors Research Projects

This paper explores the process of our leadership experience project on the topic of community gardens. Initially, our proposed research question was where in Akron area is the best location to build a community garden? Based on the primary and secondary research conducted, building a community garden would not be feasible or needed. Our conclusion showed that the real need and importance within the community was an education program on the topic of community gardens rather than planting a real garden. Therefore, the research question was revised to develop an education program focusing on healthy eating, victory gardens, and pollination …
