The results demonstrated that root and shoot dry biomass of wheat grown in soil mixed with biochar and combined with P. putida TSAU1 were …

Comparative Growth, Hydraulic Conductivity, And Sap Flow Responses Of Seedlings Of Two Pyrus Species To Drought Stress, Sheng Yang, Bin Xie, Liulin Li

Turkish Journal of Agriculture and Forestry

Drought is one of the major abiotic stresses limiting the advancement of the pear industry in the arid and semiarid regions of China. Currently, the production of pear seedlings mainly depends on the grafting propagation of rootstocks from Pyrus betulaefolia Bunge and Pyrus calleryana Decne. However, limited information is available on the drought stress potential of these rootstocks. Here, we conducted pot experiments with controlled watering conditions on both rootstocks' seedlings and compared their growth, plant hydraulic conductivity, and stem sap flow velocity. Both rootstocks' seedlings were challenged with three drought regimes i.e. light (LD), moderate (MD), and heavy (HD) …

Integrated Vs. Specialized Farming Systems For Sustainable Food Production: Comparative Analysis Of Systems’ Technical Efficiency In Nebraska, Maroua Afi, Jay Parsons

Department of Agricultural Economics: Faculty Publications

Complementarities between crops and livestock production have the potential to increase input use efficiency and maintain a diversified livelihood. This paper uses non-parametric data envelopment analysis (DEA) to assess the technical efficiency (TE) of integrated crop–livestock systems (ICLS) compared to specialized cropping and specialized livestock systems in the state of Nebraska, in the central United States. We classify each county of Nebraska into one of three systems according to their dominant agricultural production revenues. We use DEA to measure the TE of each county compared, first, to a group production frontier (in-system comparison) and second, to a metafrontier (cross-system comparison). …

Measuring And Preliminary Modeling Of Drift Interception By Plant Species, Jonnie B. Dunne, Shanique L. Grant, Jeffrey A. Golus, Jeffrey W. Perine, Stefan Wolf, Michael Winchell, T. Mark Ledson, Ian Whenham

West Central Research and Extension Center, North Platte

Currently, the concept of plant capture efficiency is not quantitatively considered in the evaluation of off-target drift for the purposes of pesticide risk assessment in the United States. For on-target pesticide applications, canopy capture efficiency is managed by optimizing formulations or tank-mixing with adjuvants to maximize retention of spray droplets. These efforts take into consideration the fact that plant species have diverse morphology and surface characteristics, and as such will retain varying levels of applied pesticides. This work aims to combine plant surface wettability potential, spray droplet characteristics, and plant morphology into describing the plant capture efficiency of drifted spray …

Application Of The Fine Sediment Biotic Index To Three Drain Tiled And Ditched Agricultural Systems In Southern Minnesota, Bailey Sanders

All Graduate Theses, Dissertations, and Other Capstone Projects

Artificial drainage is a common agricultural management technique in the United States used to remove excess water from poorly drained soils. Approximately 22.48 million hectares of crop land are drain-tiled in the United States, providing long-term economic benefits to farmers. However, artificial drainage increases sediment transport in agricultural watersheds, which can degrade aquatic systems, destroy habitats, and limit biological diversity. Biotic indices based on benthic macroinvertebrates are commonly used to assess surface water quality, but recent studies show potential in developing sediment biotic indices using benthic macroinvertebrates to estimate fine sediment in streams. The objective of this study was to …

Evaluation Of Micro-Dwarf Tomato Cultivars For Controlled Environment Research, Noah Langenfeld, Bruce Bugbee

Dwarf Crops

Controlled environment research on tomato (Solanum lycopersicum) is often hindered by large plant size. Desired cultivar traits for research include a compact plant size, fast flowering time, and good fruit set. We grew eight micro-dwarf tomato cultivars to examine their suitability as model plants for research. The cultivar ‘Rejina Red’ had the highest harvest index and most ripe fruits among the red-fruited cultivars; ‘Jochalos’ had the highest harvest index and most ripe fruits among the yellow-fruited cultivars. ‘Microtina’ had a higher harvest index than ‘Rosy Finch’, but fruits were smaller, and growth was less determinate. ‘Monetka’ had a …

Enhancement Of Developmental Defects In The Boron-Deficient Maize Mutant Tassel-Less1 By Reduced Auxin Levels, Michaela S. Matthes, Norman B. Best, Janlo M. Robil, Paula Mcsteen

Biology Faculty Publications

Background

Plant responses to deficiencies of the micronutrient boron are diverse and go beyond the well-characterized function of boron in cell wall crosslinking. To explain these phenotypic discrepancies, hypotheses about interactions of boron with various phytohormones have been proposed, particularly auxin. While these hypotheses are intensely tested in the root meristem of the model species, Arabidopsis thaliana, studies in crop species and the shoot are limited.

Aims

To address potential boron–auxin interactions during the vegetative and reproductive development of the crop maize (Zea mays), we utilized the boron-deficient tassel-less1 (tls1) mutant and the auxin-deficient vanishing tassel2 (vt2) mutant. We investigated …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Epigenetic Regulation Of Insect Development, Yaoyu Jiao

Theses and Dissertations--Entomology

Insects undergo a series of distinct life stages such as egg, larva and pupa to develop into mature adults capable of reproduction throughout their life cycle. In the larval stage, insects experience the fastest growth with voracious feeding and multiple cuticle shedding resulting in hundreds-of-fold increasing of size. During metamorphosis, insects stop increasing body size but go through dramatic tissue transformation, developing wings and other adult features. The characteristic mode of insect development, especially the metamorphosis, makes insects the most successful group of animals on the earth. However, the epigenetic mechanisms behind insect development remain elusive. Studying the epigenetic regulation …

Tedera: A Guide To Growing And Utilising This Perennial Pasture Legume, Daniel Real

Animal production and livestock published reports

The commercial release of a new pasture species is a rare and, potentially, important event. In the case of tedera (Bituminaria bituminosa var. albomarginata) we have a novel perennial pasture legume with characteristics which set it apart from anything currently available to growers in Australia or internationally.

Specifically, it is a drought-tolerant, highly productive perennial pasture with the capacity to provide nutritious forage, especially when other feed sources are scarce. Its reaction to drought is in contrast with the few successful perennial legumes available for Mediterranean climatic zones, such as lucerne, as it retains green leaves when water stressed, allowing …

1 H-Cyclopropa[B]Naphthalene: A Novel Ethylene Antagonist For Extending Storage Life And Maintaining Quality Of Climacteric And Suppressed Climacteric Plums, Poe N. Kyaw, Zora Singh, Vijay Y. Tokala

Research outputs 2022 to 2026

Ethylene is a key trigger that governs the rate of fruit ripening, storability, and postharvest quality of fresh fruit. Efficient inhibition of ethylene action is essential to slow down the postharvest ripening processes, extend storage life and maintain optimum fruit quality during storage. Ethylene antagonist compounds with the likelihood of application as liquid formulation would facilitate managing ethylene broadly as both preharvest and/or postharvest treatments. This study examined the effects of different aqueous formulations of 1 H-cyclopropa[b]naphthalene (NC) as an ethylene antagonist in the cold stored (1 °C) Japanese plums ‘Angeleno’ (suppressed-climacteric) and ‘Tegan Blue’, which exhibit climacteric peaks, respectively. …

Building No-Tillage Maize Nitrogen Recommendation Algorithm That Considers Improvements In Soil Health, Dwarika Bhattarai

Electronic Theses and Dissertations

In long-term no-till fields, farmers have reported that less N is required to optimize maize (Zea mays L.) yields in long term no-tillage fields than conventional tillage fields. These reductions may be attributed to improved soil health resulting from increasing soil organic matter, higher soil microbial activities, and improved water and nutrient use efficiency. However, the impact of soil health measurements on fertilizer-N requirement has not been determined. The objective of this dissertation was to compare different regional N recommendation models to measured values and develop a maize fertilizer-N recommendation model, using machine learning approaches, that includes adjustments based on …
