Response Of Drought Tolerant And Conventional Corn To Limited Irrigation, I. Kisekka, F. Lamm, J. D. Holman

Kansas Agricultural Experiment Station Research Reports

With declining water levels in the Ogallala aquifer, many wells cannot supply peak irrigation water needs for corn. Emerging drought-tolerant (DT) corn hybrids could help farmers maintain yield with limited capacity wells. A knowledge gap exists comparing transgenic DT and conventional corn hybrids in yield response to water level. The purpose of this study was to compare yield, yield components, water productivity, and irrigation water use efficiency response of DT corn with cspB (DKC 6267 DGVT- 2PRO) transgene trait and conventional corn hybrid (DKC 62-98 VT2PRO) with similar maturity to full and limited irrigation. Preliminary results from the 2014 growing ...

Irrigation Scheduling Based On Soil Moisture Sensors And Evapotranspiration, J. Aguilar, D. Rogers, I. Kisekka

Kansas Agricultural Experiment Station Research Reports

Irrigation scheduling is crucial to effectively manage water resources and optimize profitability of an irrigated operation. Tools that can be customized to a field’s characteristics can greatly facilitate irrigation scheduling decisions. Soil moisture sensors and the evapotranspiration (ET)-based KanSched are two of the tools that could be implemented in an irrigated farm. Focusing on the installation of soil moisture sensors, demonstration set-ups were established at the Southwest Research-Extension Center plots in Garden City, Kansas, and in a producer’s field, each with three types of moisture sensors at different depths. Among others, this project validates the importance of ...


Challenges And Opportunities In Understanding Microbial Communities With Metagenome Assembly (Accompanied By Ipython Notebook Tutorial), Adina C. Howe, Patrick S. G. Chain 2015 Iowa State University

Challenges And Opportunities In Understanding Microbial Communities With Metagenome Assembly (Accompanied By Ipython Notebook Tutorial), Adina C. Howe, Patrick S. G. Chain

Agricultural and Biosystems Engineering Publications

Metagenomic investigations hold great promise for informing the genetics, physiology, and ecology of environmental microorganisms. Current challenges for metagenomic analysis are related to our ability to connect the dots between sequencing reads, their population of origin, and their encoding functions. Assembly-based methods reduce dataset size by extending overlapping reads into larger contiguous sequences (contigs), providing contextual information for genetic sequences that does not rely on existing references. These methods, however, tend to be computationally intensive and are again challenged by sequencing errors as well as by genomic repeats While numerous tools have been developed based on these methodological concepts, they ...

Controller Area Network (Can) Bus J1939 Data Acquisition Methods And Parameter Accuracy Assessment Using Nebraska Tractor Test Laboratory Data, Samuel E. Marx

Biological Systems Engineering--Dissertations, Theses, and Student Research

Electronics have become a standard in agricultural equipment and the trend of “smarter” equipment is on the rise. To have “smarter” equipment, a working knowledge of the accuracy of the data being transmitted throughout that equipment is needed. The controller area network (CAN) bus is the current interface to machine operation data transmitted between electronic control units (ECUs).

Because CAN bus has been around for nearly thirty years, numerous devices have been created for interfacing with the bus. Choosing a device can be a challenge, especially without knowing if there are differences between the logging methods for true data representation ...


Evaluation Of Multiple Disinfection Methods To Mitigate Contaminated Irrigation Water, Tianju Chang 2015 University of Tennessee - Knoxville

Evaluation Of Multiple Disinfection Methods To Mitigate Contaminated Irrigation Water, Tianju Chang

Masters Theses

Outbreak of foodborne pathogens associated with fresh produce is a concern to produce growers. Irrigation water is one of the pathways of produce contamination. The U.S. Food and Drug Administration (FDA) proposed a set of guidelines for irrigation water that includes a maximum generic E.coli count lower than 126MPN/100mL. Irrigation is typically a continuous-flow process: water is withdrawn from a source and applied to a crop. In order to disinfect irrigation water, a process must be developed to provide treatment while the water is in the hydraulic network. However, studies related to the continuous flow irrigation water ...


A Finite Element Method Based Microwave Heat Transfer Modeling Of Frozen Multi-Component Foods, Krishnamoorthy Pitchai 2015 University of Nebraska at Lincoln

A Finite Element Method Based Microwave Heat Transfer Modeling Of Frozen Multi-Component Foods, Krishnamoorthy Pitchai

Dissertations & Theses in Food Science and Technology

Microwave heating is fast and convenient, but is highly non-uniform. Non-uniform heating in microwave cooking affects not only food quality but also food safety. Most food industries develop microwavable food products based on “cook-and-look” approach. This approach is time-consuming, labor intensive and expensive and may not result in optimal food product design that assures food safety and quality. Design of microwavable food can be realized through a simulation model which describes the physical mechanisms of microwave heating in mathematical expressions. The objective of this study was to develop a microwave heat transfer model to predict spatial and temporal profiles of ...

Pay Attention To Stored Grain, Charles R. Hurburgh 2015 Iowa State University

Pay Attention To Stored Grain, Charles R. Hurburgh

Integrated Crop Management News

The first significant warmup of the year should be a reminder to check stored grain frequently. If good practices were followed through the fall and winter seasons, grain temperatures should be in the 30s or below. Grain moistures last fall were above average, and there are many bins with corn moistures in the range of 16-20%. This wetter grain will spoil quickly if grain temperatures rise.

Impact Of Commercial Housing Systems And Nutrient And Energy Intake On Laying Hen Performance And Egg Quality Parameters, D. M. Karcher, D. R. Jones, Z. Abdo, Yang Zhao, Timothy A. Shepherd, Hongwei Xin

Agricultural and Biosystems Engineering Publications

The US egg industry is exploring alternative housing systems for laying hens. However, limited published research related to cage-free aviary systems and enriched colony cages exists related to production, egg quality, and hen nutrition. The laying hen's nutritional requirements and resulting productivity are well established with the conventional cage system, but diminutive research is available in regards to alternative housing systems. The restrictions exist with limited availability of alternative housing systems in research settings and the considerable expense for increased bird numbers in a replicate due to alternative housing system design. Therefore, the objective of the current study was ...
