Exploring The Role Of Salt-Tolerant Halomonas Inoculant In Altering Plant Gene Expression To Improve Salt Tolerance In Alfalfa., Ashley Kay Miller
Exploring The Role Of Salt-Tolerant Halomonas Inoculant In Altering Plant Gene Expression To Improve Salt Tolerance In Alfalfa., Ashley Kay Miller
Theses and Dissertations
Soil salinity is an increasing problem facing agriculture in many parts of the world. Climate change and irrigation practices have led to decreased yields of large areas of farmland due to increased salt levels in the soil. Irrigation introduces salts to the soil that with time accumulate and threaten crop yield. In arid climates like Utah, the practice of irrigation is especially threatening to salt-sensitive crops including alfalfa (Medicago sativa). Plants that have tolerance to salt are needed to feed livestock and the world's population. One approach to address this problem is to introduce genes encoding salt tolerance into the …
Can Alfalfa Nutrient Concentrate Serve As A Feed Ingredient For Feeding Juvenile Yellow Perch (Perca Flavescens)?, William J. Sullivan
Can Alfalfa Nutrient Concentrate Serve As A Feed Ingredient For Feeding Juvenile Yellow Perch (Perca Flavescens)?, William J. Sullivan
Theses and Dissertations
This study evaluated the potential of alfalfa nutrient concentrate (ANC) used in feed for yellow perch. We assessed the quality of ANC based on pellet functionality, digestibility, and growth performance of perch fed with diets including various levels of ANC (0-20 g/100 g diet) to replace fishmeal protein in a control diet based on a 9-week feeding with three replications per diet. Pellet bulk density, durability, water stability, and oil retention capacity increased with fishmeal replacement. Growth rate, feed conversion ratio, satiation feed intake, and protein retention were similar for fish fed different diets (P>0.05). Fish fed ANC-20 had …
Pressurized Hot Water And Dtpa-Sorbitol, Viable Alternatives For Soil Boron Extraction, Amanda Kathryn Shiffler
Pressurized Hot Water And Dtpa-Sorbitol, Viable Alternatives For Soil Boron Extraction, Amanda Kathryn Shiffler
Theses and Dissertations
Pressurized hot water and DTPA-Sorbitol are two relatively new soil boron (B) extraction methods with potential to replace the cumbersome hot water extraction. The objective of this research is to produce data in support of acceptance or rejection of these two alternative B extractions. The three soil tests were used to extract B from samples of calcareous sand and silt loam and limed, loamy fine sand treated with 10 levels of B and incubated for 7 and 28 d. As B application increased so did extractable B with each extraction method. High correlations (r of 0.977 to 0.999) were observed …
Efficiency Of The Inorganic Fertilization In The Cultivation Of Alfalfa (Medicated Sativa L) And Whitewashing For The Correction Of The Ph Of The Soil, Alex Gonzalo Bravo Morocho
Efficiency Of The Inorganic Fertilization In The Cultivation Of Alfalfa (Medicated Sativa L) And Whitewashing For The Correction Of The Ph Of The Soil, Alex Gonzalo Bravo Morocho
Theses and Dissertations
In our country the necessity to offer new alternatives for the agricultural sector is high-priority especially for the lucern cultivation that every day is surface cultivated especially in the Chimborazo province increases; for what is of our interest to establish the answer from the cultivation to the inorganic fertilization and liming for the flora pH correction, for this way to obtain better yields and for consequence to improve the economic conditions of the farmers. With the result that the titled investigation: Efficiency of the Inorganic Fertilization in the Alfalfa Cultivation (Medicago sativa L) and Liming for the Correction of the …
The Study Of Alfalfa (Medicago Sativa) Production In The Community Of El Troje, Juan Leopoldo Penafiel Alvarado
The Study Of Alfalfa (Medicago Sativa) Production In The Community Of El Troje, Juan Leopoldo Penafiel Alvarado
Theses and Dissertations
The alfalfa harvest in Ecuador constitutes one of the most important activities, especially as a primary product for animal feeding. The crop is widely distributed in the mountain region of the country. It is important to have studies on the production systems, which facilitate a real and compete vision of those characteristics that interact among them in the agricultural production. With this knowledge it will be possible to look for the most adequate solutions to the conditions of the area where alfalfa is produced. The objectives of the study reported herein were: 1. To make an agricultural, social and economical …
Light And Electron Microscopy Of Resistant And Susceptible Alfalfa Roots Infected By Meloidogyne Hapla, Bernard Al Tait
Light And Electron Microscopy Of Resistant And Susceptible Alfalfa Roots Infected By Meloidogyne Hapla, Bernard Al Tait
Theses and Dissertations
Resistant (65-410 and 65-393) and susceptible (breeders Lahontan) alfalfa seedlings were infected with the Northern root-knot nematode, Meloidogyne hapla. Infected roots were fixed, stained, and embedded in plastic for ultrastructural investigations. Sections of plastic embedded tissue, cut at 0.5-1.5 microns for light microscopy investigations, were stained with various histochemical stains to determine the chemical composition of the nematode-altered tissues. In the susceptible cultivar, giant cells were formed by enlargement of nematode-stimulated cells without cell wall lysis. The giant cells became multinucleate by karyonkinesis without cytokinesis. Proplastids in the giant cells became structurally altered to form tubular complexes. The resistant plants …
