Micronutrient Availability In Alternative Foods During Agricultural Catastrophes, David Denkenberger, Joshua M. Pearce Oct 2018

Micronutrient Availability In Alternative Foods During Agricultural Catastrophes, David Denkenberger, Joshua M. Pearce

Civil and Architectural Engineering Faculty Research

Several catastrophes could block the sun, including asteroid/comet impact, super volcanic eruption, and nuclear war with the burning of cities (nuclear winter). Previous work has analyzed alternate food supplies (e.g., mushrooms growing on dead trees, bacteria growing on natural gas). This was shown to be technically capable of feeding everyone with macronutrients (protein, carbohydrates, and lipids) and minerals, although economics and politics remain uncertain. The present work analyzes vitamin availability in such alternative food scenarios. The vitamin content of various alternate foods is compared to the US recommended daily allowance (RDA) as well as the average requirement defined by the …


Greenhouse Gas Emissions And Crop Yield In No-Tillage Systems: A Meta-Analysis, Yawen Huang, Wei Ren, Lixin Wang, Dafeng Hui, John H. Grove, Xiaojuan Yang, Bo Tao, Ben Goff Sep 2018

Greenhouse Gas Emissions And Crop Yield In No-Tillage Systems: A Meta-Analysis, Yawen Huang, Wei Ren, Lixin Wang, Dafeng Hui, John H. Grove, Xiaojuan Yang, Bo Tao, Ben Goff

Biology Faculty Research

No-tillage (NT) has been touted as one of several climate-smart agriculture (CSA) management practices that improve food security and enhance agroecosystem resilience to climate change. However, the sustainable effectiveness of NT greatly depends on trade-offs between NT-induced changes in crop yield and greenhouse gas (GHG, i.e. CH4, CO2, and N2O) emissions. Such trade-offs are regulated by climate fluctuations and heterogeneous soil conditions and have not been well addressed. Supporting CSA management decisions requires advancing our understanding of how NT affects crop yield and GHG emissions in different agroecological regions. In this study, a meta-analysis was conducted using 740 paired measurements …


Association Of Proteomics Changes With Al-Sensitive Root Zones In Switchgrass, Mahesh Rangu, Zhujia Ye, Sarabjit Bhatti, Suping Zhou, Yong Yang, Tara Fish, Theodore W. Thannhauser Mar 2018

Association Of Proteomics Changes With Al-Sensitive Root Zones In Switchgrass, Mahesh Rangu, Zhujia Ye, Sarabjit Bhatti, Suping Zhou, Yong Yang, Tara Fish, Theodore W. Thannhauser

Agricultural and Environmental Sciences Faculty Research

In this paper, we report on aluminum (Al)-induced root proteomic changes in switchgrass. After growth in a hydroponic culture system supplemented with 400 μM of Al, plants began to show signs of physiological stress such as a reduction in photosynthetic rate. At this time, the basal 2-cm long root tips were harvested and divided into two segments, each of 1-cm in length, for protein extraction. Al-induced changes in proteomes were identified using tandem mass tags mass spectrometry (TMT-MS)-based quantitative proteomics analysis. A total of 216 proteins (approximately 3.6% of total proteins) showed significant differences between non-Al treated control and treated …


Land Cover Land Use Mapping And Change Detection Analysis Using Geographic Information System And Remote Sensing, C. E. Akumu, S. Dennis, C. Reddy Jan 2018

Land Cover Land Use Mapping And Change Detection Analysis Using Geographic Information System And Remote Sensing, C. E. Akumu, S. Dennis, C. Reddy

Agricultural and Environmental Sciences Faculty Research

Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict change detection areas in Davidson County, Tennessee. The land cover/land use categories were classified using maximum likelihood algorithm and post classification comparison change detection analysis was performed. Classified image differencing technique was also used to …

Yield Performance Of Organic Sweetpotato Varieties In Various Mulches, Sochinwechi Nwosisi, Dilip Nandwani, Bharat Pokharel Aug 2017

Yield Performance Of Organic Sweetpotato Varieties In Various Mulches, Sochinwechi Nwosisi, Dilip Nandwani, Bharat Pokharel

Agricultural and Environmental Sciences Faculty Research

Interest in organic sweetpotato production in the United States has been growing as consumers and producers are becoming increasingly concerned about how their food is cultivated. Thus, there is a growing need for information on sweetpotato production and variety selection under an organic management production system. The objective of this study was to evaluate the effects of various mulches on yields—total and marketable—of fourteen sweetpotato varieties grown under organic management. Three types of mulch, wheat straw, pine needle, and black plastic, and a control (no mulch) were evaluated during the 2016 growing season. The wheat straw mulch yielded significantly higher …

Effects Of Precipitation Changes On Aboveground Net Primary Production And Soil Respiration In A Switchgrass Field, Qi Deng, Sadiye Aras, Chih-Li Yu, Kudjo E. Dzantor, Philip A. Fay, Yiqi Luo, Weijun Shen, Dafeng Hui

Biology Faculty Research

Switchgrass (Panicum virgatum L.) is widely selected as a model feedstock for sustainable replacement of fossil fuels and climate change mitigation. However, how climate changes, such as altered precipitation (PPT), will influence switchgrass growth and soil carbon storage potential have not been well investigated. We conducted a two-year PPT manipulation experiment with five treatments: −50%, −33%, +0%, +33%, and +50% of ambient PPT, in an “Alamo” switchgrass field in Nashville, TN. Switchgrass aboveground net primary production (ANPP), leaf gas exchange, and soil respiration (SR) were determined each growing season. Data collected from this study was then used to test whether …

Modeling Net Energy Balance Of Ethanol Production From Native Warm Season Grasses, Prabodh Illukpitiya, Chandra Reddy, Ankit Bansal

Agricultural and Environmental Sciences Faculty Research

There has been an increasing interest in the use of perennial grasses as potential feedstock for ethanol production. The characteristics which make perennial grasses attractive for bioenergy feedstock development initiative are their high yield potential and the high contents of lignin and cellulose. The objective of the study is to model energy input and output and simulate Net Energy Value (NEV) of producing ethanol from native warm season grasses. According to simulated results, the mean NEV of ethanol production from native warm season grasses considered in the analysis was positive. Mean NEV for switchgrass and eastern gammagrass was higher compared …

The impact of chemical farming and the negative consequences on the environment and human health in Bangladesh are on the rise. Organic farming is gaining attention and increasing globally because it is eco-friendly, safe and has benefits for human health. A field study was conducted at the horticulture farm of Bangladesh Agricultural University (BAU), Mymensingh, to evaluate the growth and yield performance of cabbage cv. Atlas—70 using organic and inorganic fertilizers in various plant spacing arrangements. Two factor experiments were conducted on plant spacings of 60 cm × 40 cm (S1), 60 cm × 50 cm (S2) and 60 cm …

Field trials were conducted on tomato for yield and quality of fruits using different types of organic and inorganic fertilizers at the horticulture farm of Bangladesh Agricultural University (BAU), Mymensingh. Fertilizer treatments were tested on two varieties of tomato ca. Roma VF and BARI 15. The fertilization treatments were T1, vermicompost (12 t/ha); T2, compost (10 t/ha); T3, integrated plant nutrient system (IPNS) or mixed fertilizers (organic 2/3 part and inorganic 1/3 part); T4, inorganic fertilizers; and a control (T5). Results showed growth and yield (20.8 t/ha) in tomato were higher in the IPNS treatment. A higher number of fruits …
