On-Farm Evaluation Of Tomato Cultivars For Disease Resistance, 2008, Elizabeth Maynard, Butch Zandstra, Dan Egel

Purdue Fruit and Vegetable Research Reports

"Bacterial spot of tomatoes (Xanthomonas campestris pv. vesicatoria) causes lesions on leaves, stems and fruit. Under conditions of hot, humid, rainy weather, defoliation can result in a loss of yield. In addition, lesions on fruit result in a direct loss of marketability. This disease is managed primarily with applications of fixed copper bactericides, crop rotations, greenhouse sanitation, and healthy seed/transplants. Even in properly managed commercial fields, however, bacterial spot can cause yield losses. Although there are no varieties with complete resistance to bacterial spot, we report here the results of an on-farm trial that indicates some varieties may have partial …

Report On Polyacrylamide, A Practice To Reduce Sediment And Insoluable Chemicals In Tailwater, Tara Slaven

Bulletins 4000 -

The main barrier to the adoption of PAM seems to the timing of the cost of outlay. This could add significantly to the initial crop establishment costs at a time of year when rowers receive no income. However, the partial and parametric analysis indicates that there re benefits from using PAM as part of the crop management cycle. These benefits are from ving water, retaining sediment on-farm and reducing the cost of delving drains. There are ther potential economic benefits including the retainment of phosphorus as a plant nutrient n-farm and subsequent yield increases.

Additionally, the off-site environmental impacts seem …

Bulked Segregant Analysis Using The Goldengate Assay To Locate The Rpp3 Locus That Confers Resistance To Soybean Rust In Soybean, D. L. Hyten, James R. Smith, Reid D. Frederick, Mark L. Tucker, Qijian Song, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Few resistance loci to soybean rust (SBR), caused by Phakopsora pachyrhizi Syd., have been genetically mapped and linked to molecular markers that can be used for marker assisted selection. New technologies are available for single nucleotide polymorphism (SNP) genotyping that can be used to rapidly map traits controlled by single loci such as resistance to SBR. Our objective was to demonstrate that the highthroughput SNP genotyping method known as the GoldenGate assay can be used to perform bulked segregant analysis (BSA) to fi nd candidate regions to facilitate effi cient mapping of a dominant resistant locus to SBR designated Rpp3 …

Department of Agronomy and Horticulture: Faculty Publications

Soybean rust, caused by Phakopsora pachyrhizi (H. Sydow & Sydow), is a destructive soybean [Glycine max (L.) Merr.] disease and identification of new resistance genes is essential for effective rust management. Our research objectives were to map and confirm the location of resistance gene(s) in PI 594538A using a population of 98 F_3:4 lines from across between PI 594538A (reddish-brown [RB] lesions) and the susceptible cultivar Loda (tan [TAN] lesions). The lines were inoculated with the P. pachyrhizi isolate ZM01-1 from Zimbabwe. The RB resistance in PI 594538A mapped on linkage group G as a single dominant gene. …

Agroecology As A Science, A Movement And A Practice: A Review, A. Wezel, S. Bellon, T. Doré, Charles A. Francis, D. Vallod, C. David

Department of Agronomy and Horticulture: Faculty Publications

Agroecology involves various approaches to solve actual challenges of agricultural production. Though agroecology initially dealt primarily with crop production and protection aspects, in recent decades new dimensions such as environmental, social, economic, ethical and development issues are becoming relevant. Today, the term ‘agroecology’ means either a scientific discipline, agricultural practice, or political or social movement. Here we study the different meanings of agroecology. For that we analyse the historical development of agroecology. We present examples from USA, Brazil, Germany, and France. We study and discuss the evolution of different meanings agroecology. The use of the term agroecology can be traced …

Detection And Validation Of Single Feature Polymorphisms Using Rna Expression Data From A Rice Genome Array, Sung-Hyun Kim, Prasanna R. Bhat, Xinping Cui, Harkamal Walia, Jin Xu, Steve Wanamaker, Abdelbagi M. Ismail, Clyde Wilson, Timothy J. Close

Department of Agronomy and Horticulture: Faculty Publications

Background: A large number of genetic variations have been identified in rice. Such variations must in many cases control phenotypic differences in abiotic stress tolerance and other traits. A single feature polymorphism (SFP) is an oligonucleotide array-based polymorphism which can be used for identification of SNPs or insertion/deletions (INDELs) for high throughput genotyping and high density mapping. Here we applied SFP markers to a lingering question about the source of salt tolerance in a particular rice recombinant inbred line (RIL) derived from a salt tolerant and salt sensitive parent. Results: Expression data obtained by hybridizing RNA to an oligonucleotide array …

Antibiotic Use In Animal Production: Environmental Concerns, Teshome H. Regassa, Richard K. Koelsch, Charles S. Wortmann, Richard F. Randle, Akwasi A. Abunyewa

Department of Agronomy and Horticulture: Faculty Publications

Introduction

Antibiotic1 use in animal production has led to improved feed use efficiency and increased growth rates. In turn, these resulted in reduced food production costs and reduced excrement of manure nutrients which may cause pollution problems.

On the other hand, antibiotic use leads to antibiotic resistance and a possible reduction in effectiveness of treatment options for both animals and humans. This publication addresses these issues.

Disease-causing microorganisms2, including bacteria,are the most diverse and numerous organisms on earth. Diverse in their habitat, environmental adaptation, and mechanisms of reproduction, they have short generations with high multiplication rates. Such characteristics help develop …

A High-Oleic-Acid And Low-Palmitic-Acid Soybean: Agronomic Performance And Evaluation As A Feedstock For Biodiesel, George L. Graef, Bradley J. Lavallee, Patrick Tenopir, Mustafa Tat, Bruce Schweiger, Anthony J. Kinney, Jon H. Van Gerpen, Thomas E. Clemente

Department of Agronomy and Horticulture: Faculty Publications

Phenotypic characterization of soybean event 335-13, which possesses oil with an increased oleic acid content (> 85%) and reduced palmitic acid content (< 5%), was conducted across multiple environments during 2004 and 2005. Under these conditions, the stability of the novel fatty acid profile of the oil was not influenced by environment. Importantly, the novel soybean event 335-13 was not compromised in yield in both irrigated and non-irrigated production schemes. Moreover, seed characteristics, including total oil and protein, as well as amino acid profile, were not altered as a result of the large shift in the fatty acid profile. The novel oil trait was inherited in a simple Mendelian fashion. The event 335-13 was also evaluated as a feedstock for biodiesel. Extruded oil from event 335-13 produced a biodiesel with improved cold flow and enhanced oxidative stability, two critical fuel parameters that can limit the utility of this renewable transportation fuel.

Evaluation Of Competition Between Turfgrass And Trees In The Landscape, Christopher A. Hendrickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional …

Dwarfing Mechanisms Of Prunus Species As Interstems And Rootstocks On Peach [Prunus Persica (L.) Batsch] Tree Vegetative Growth And Physiology, Antonio Weibel

All Dissertations

The use of small trees in orchard systems reduces manual labor (pruning, thinning and harvesting), and induces precocity, thus making high-density plantations economically advantageous, which has elicited an interest in size-controlling rootstocks. However, the mechanisms involved in the reduction of scion growth by the rootstock are not well understood. The main objective of this study was to gain a better understanding of the dwarfing mechanism induced by size-controlling peach rootstocks. The relationship among different rootstocks (dwarfing to invigorating range) as to stored carbohydrates, tree water status, and interstem and grafting height was evaluated on young and mature `Redhaven' and `Redtop' …

Soil Moisture Responses In Traditional And Drought Adapted Landscapes In The Intermountain West, James Gregory

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Water conservation in the Intermountain West will be an important issue in the future as population and demand for limited water resources increases. In Utah, outdoor water use accounts for up to 60% of total per capita water use with 67% of that outdoor water being used to irrigate non native plant species to maintain a uniform green appearance. The objective of this study was to measure intra landscape changes in soil water potential during a 21.5 day dry down from DOY 215 to 236.5 in the summer of 2005 and 2006. Four, 2 x 2 replicated traditional and drought …

Pomegranates - New Woolbelt Opportunities, Department Of Agriculture And Food, Western Australia

Horticulture published reports

The capture of fresh surface water has the potential to open up areas of the 'woolbelt' of Western Australia to intensive agricultural industries.

In 2005-06 the Department of Agriculture and Food (DAFWA) investigated surface run-off in the medium rainfall zone (500-825 mm) of south-western Australia. It aimed to identify areas with sufficient freshwater resources and suitable land for intensive production.

The scoping study, based on broad scale modelling and land-soil capability assessment, found that there was some potential to develop large reliable water supplies to support perennial horticulture.
