Evaluation Of Nutrient Solutions Produced From Aqueous Extracts And Decomposition Products Of Organic Waste Materials On The Plant Growth Performance In Hydroponics, Noura Said Al Nuaimi

Theses

Hydroponic plant production involves the cultivation of plants in absence of soil. In this system, the supply of the plant root with water and nutritional elements occurs via a nutrient solution made of inorganic salts. Hydroponic plant cultivation often achieves higher yields, water use efficiencies and quality of crops compared with soil production. In addition, it renders the farming system independent from soil properties. However, the currently available systems rely on the steady input of non-renewable inorganic salts. Unlike soil-based systems, hydroponics, so far, do not offer feasible opportunities for recycling nutritional elements from within crop residues or organic waste …

Interactive Effects Of Soil And Browsing On Big Sagebrush: Implications For Restoration Success, Kyle Nehring

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Heterogeneity in landscape conditions (e.g., soil types) precludes a “one size fits all” management strategy across large landscapes. New management approaches that explicitly account for heterogeneous landscapes (and the variable conditions therein) will be required to maintain habitat quality. In particular, we require an improved mechanistic understanding of how the outcomes of conservation and restoration actions are contingent upon a) contextual abiotic factors (e.g., moisture availability mediated by soils and precipitation) and b) their interactions with biotic factors (e.g., browsing wildlife).

We propose to answer fundamental questions about how big sagebrush (Artemisia tridentata), the foundational species for sagebrush …

Estimation Of Spatial Change In Cropland Area And Evaluation Of Irrigation Performance In Imperial Valley Using Remotely Sensed Data, Usha Poudel

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Imperial Valley (IV) in the US is an extensively irrigated agricultural region, which includes multiple crops changing on an annual and semiannual basis. The valley is facing grave concerns about water management due to its semi-arid environment, water intensive crops, and limited water supply. A simple, inexpensive, and repeatable method to detect changes in cropping patterns may assist irrigation managers to understand crop diversification and associated consumptive use. In addition, a spatial assessment of existing water irrigation system performance and productivity is crucial to benchmark and improve current water management strategies. This thesis estimates the spatial pattern of change …

Origin Of Agricultural Plant Pathogens: Diversity And Pathogenicity Of Rhizoctonia Fungi Associated With Native Prairie Grasses In The Sandhills Of Nebraska, Srikanth Kodati, Anthony O. Adesemoye, Gary Y. Yuen, Jerry Volesky, Sydney E. Everhart

Department of Plant Pathology: Faculty Publications

The Sandhills of Nebraska is a complex ecosystem, covering 50,000 km² in central and western Nebraska and predominantly of virgin grassland. Grasslands are the most widespread vegetation in the U.S. and once dominated regions are currently cultivated croplands, so it stands to reason that some of the current plant pathogens of cultivated crops originated from grasslands, particularly soilborne plant pathogens. The anamorphic genus Rhizoctonia includes genetically diverse organisms that are known to be necrotrophic fungal pathogens, saprophytes, mycorrhiza of orchids, and biocontrol agents. This study aimed to evaluate the diversity of Rhizoctonia spp. on four native grasses in the …

Phenotypic Plasticity Of Diverse Sorghum Varieties In Response To Nitrogen Deficit Stress, Mackenzie Zwiener

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The movement of nutrients from old vegetative tissue to young leaves and reproductive organs is known as senescence. Senescence can be influenced by the environment of a plant, such as, drought, heat, and nutrient stress. These environmental stressors can also influence canopy architecture. Crop canopy consists of several traits including: leaf number, angle, length and width. Past research in crops like maize and rice have shown significant influences of more erect leaves, including, the ability for increased planting density, which optimizes light interception and increases yield. In a field trial of a sorghum association panel including 345 different sorghum varieties …

Short And Long Term Effects Of Lime And Gypsum Applications On Acid Soils In A Water-Limited Environment: 3. Soil Solution Chemistry, Geoff Anderson, Shahab Pathan, David Hall, Rajesh Sharma, James Easton

Grain and Other Field Crops Research Articles

Aluminum (Al) toxicity imposes a significant limitation to crop production in South Western Australia. This paper examines the impact of surface-applied lime and gypsum on soil solution chemistry in the short term (1 year) and the long-term (10 years) in water limited environments. In the experiments, we measured soil solution chemistry using a paste extract on soil profile samples collected to a depth of 50 cm. We then used the chemical equilibrium model MINTEQ to predict the presence and relative concentrations of Al species that are toxic to root growth (Al associated with Al3+ and AlOH2 or Toxic-Al) and less …

Jurnal Kultivasi

Teh (Camellia sinensis L.(O) Kuntze) merupakan tanaman tahunan yang pucuknya rutin dipetik, sehingga proses fotosintesis harus optimal. Fotosintesis adalah proses fisiologis yang bertanggung jawab dalam hampir semua akumulasi bahan kering pada tanaman. Peningkatan bahan kering adalah bagian yang paling penting untuk analisis kuantitatif pertumbuhan tanaman. Tujuan penelitian ini adalah untuk menganalisis pertumbuhan pada tanaman teh setelah diberikan perlakuan jenis pangkasan, tinggi pangkasan, dan zat pengatur tumbuh. Percobaan dilaksanakan di Kebun Percobaan Pusat Penelitian Teh dan Kina, Gambung, Ciwidey. Penelitian dimulai Juli 2018 hingga Oktober 2018. Penelitian dilakukan secara deskriptif dengan membentuk model regresi polinomial untuk menentukan tinggi pangkasan dan konsentrasi …

Allelic Diversity At Abiotic Stress Responsive Genes In Relationship To Ecological Drought Indices For Cultivated Tepary Bean, Phaseolus Acutifolius A. Gray, And Its Wild Relatives, María A. Buitrago-Bitar, Andrés J. Cortés, Felipe López-Hernández, Jorge M. Londoño-Caicedo, Jaime E. Muñoz-Florez, L. Carmenza Muñoz, Matthew Wohlgemuth Blair

Agricultural and Environmental Sciences Faculty Research

Some of the major impacts of climate change are expected in regions where drought stress is already an issue. Grain legumes are generally drought susceptible. However, tepary bean and its wild relatives within Phaseolus acutifolius or P. parvifolius are from arid areas between Mexico and the United States. Therefore, we hypothesize that these bean accessions have diversity signals indicative of adaptation to drought at key candidate genes such as: Asr2, Dreb2B, and ERECTA. By sequencing alleles of these genes and comparing to estimates of drought tolerance indices from climate data for the collection site of geo-referenced, tepary bean accessions, we …
