Linking Soil Properties to Originally Wooded and Afforested Areas

Matthew Laun, Ashton Crowe

Mentor: I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …

Foliar Application Of Acetic Acid And Effectiveness Against Drought At Different Time Points In Soybean (Glycine Max) Development, Miranda Rudolph, Megan Taylor Phd.

Posters-at-the-Capitol

Drought is arguably the most serious environmental factor affecting crop production today. A plant's response to drought stress is extremely complex, affecting numerous metabolic pathways that are all interconnected in their responses. Due to this complex nature, scientists do not fully understand the implications of different treatments and how they affect these processes. Acetic acid has been shown to improve plant growth and resistance to drought stress, but exactly how it accomplishes this is also unknown. Soybeans (Glycine max) are one of the most important crops worldwide and can suffer significant yield loss due to drought stress. As climate change …

Economic Feasibility And Consumer Acceptance Of Strawberry Plants As An Additional Offering In Fall Mum Sales, Alyx Shultz, Eva Bogue, Anna Griggs, Allison Croslin

Posters-at-the-Capitol

As consumers become more health conscious and concerned with food production practices, increased market demand had developed for edible plants with ornamental properties. This action research examined the economic feasibility, production realities, and consumer acceptance of offering garden and alpine strawberries at fall mum sales. Each year $173 million in mums are sold in the United States. By offering potted strawberries for sale alongside mums, Kentucky producers may be able to mitigate their risk as well as generate additional on-farm revenue from a proven consumer base and market. Researchers grew 100 garden strawberries and 100 alpine strawberries and offered the …

The research was based on forest inventory data from 1972, 1982, 2002, and 2021 (the study was conducted on a limited territory). There was a steady increase in temperatures in the growing season from 1982 to 2002. The amount …

Ecological Complexity And Avoiding Pest Resurgence: Intuitions From Mathematical Ecology, Theresa Ong, John H. Vandermeer

Dartmouth Scholarship

Pest resurgence is defined by a predictable increase in pests following declines resulting from the implementation of pest management practices. This phenomenon is notorious; familiar in biblical references to cyclical plagues of locust and discussions of pesticide treadmills, where pests resurge following the evolution of pesticide resistance. Targeted “silver-bullet” approaches, whether chemical, mechanical, biological, or genetic in nature, apply a reductionist lens toward the removal of a specific target pest, often ignoring ecological context, by application of said silver-bullet. In this review article, we cover how past and recent developments in theoretical ecology and complex systems dynamics provide a general …

Editorial: Genetic Validation And Its Role In Crop Improvement, Ahmed Sallam, Ahmad M. Alqudah, P. Stephen Baenziger, Awais Rasheed

Department of Agronomy and Horticulture: Faculty Publications

Gene discovery for economically important traits has remained a challenging Frontier in crop genomics and breeding. The recent advances in DNA sequencing technologies and genetic analysis approaches paved the way for discovering many genes and hotspot genomic regions controlling target traits. The detection of novel genomic regions or candidate genes is very useful for plant breeders and geneticists to improve crops, dissect the genetics of complex traits, and understand the biological mechanisms of genes underpinning traits of interest. Quantitative trait loci (QTL) mapping and genome-wide association studies (GWAS) dominated recent crop gene discovery research. These studies are becoming routine activities …

The Intertwining Of Zn-Finger Motifs And Abiotic Stress Tolerance In Plants: Current Status And Future Prospects, Debojyoti Moulick, Karma Landup Bhutia, Sukamal Sarkar, Anirban Roy, Udit Nandan Mishra, Biswajit Pramanick, Sagar Maitra, Tanmoy Shankar, Swati Hazra, Milan Skalicky, Marian Brestic, Viliam Barek, Akbar Hossain

Department of Agronomy and Horticulture: Faculty Publications

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering the morphological, physiological, and biochemical processes of the plants. It is estimated that about 50% + of the productivity of several crops is limited due to various types of abiotic stresses either presence alone or in combination (s). However, there are two ways plants can survive against these abiotic stresses; a) through management practices and b) through adaptive mechanisms to tolerate plants. These adaptive mechanisms of tolerant plants are mostly linked to their signalling transduction pathway, triggering the action of plant …

Community Supported Agriculture Values: A Comparison Across Groups, Thomas B. Pierce

Theses and Dissertations--Agricultural Economics

Community Supported Agriculture (CSA) programs offer consumers the chance to share the risk with farming operations while gaining access to fresh, local foods. While research on CSA shareholder values such as share affordability or the local impact of participation has been conducted in the past decade and beyond, less attention has been paid to direct value-mapping of the shareholders themselves. This research seeks to determine consumer values around the CSA purchasing decision using the Best-Worst Scaling Approach. Based on a focus group discussion with CSA shareholders in a university wellness voucher program, we used affinity diagramming to develop a list …

The Molecular Regulators, Pathways, And Environmental Impacts Of White Flowers, Sagheer Ahmad, Zaibun Nisa, Muhammad Zeeshan Munir, Muhammad Imran, Shaista Nosheen, Kai Zhao

Turkish Journal of Agriculture and Forestry

White flowers are an important element of natural beauty, although they are thought of colorless. Anthocyanins are the major compounds responsible for a variety of pigments in flowers. White flowers surely lack pigmented anthocyanins and other compounds, but there are regulatory mechanisms that hinder the deposition of color pigments in white flowers. Moreover, there are also some compounds that deposit to instigate white appearance and the genetic regulators control the biosynthesis and deposition of such compounds. Experts have shown that fluctuation in the equilibrium of FLS and DFR genes determines the degree of accumulation of anthocyanins and flavonols in the …

A Concise Study On Essential Parameters For The Sustainability Of Lagoon Waters In Terms Of Scientific Literature, Shuraik Kader, Morufu Olalekan Raimi, Velibor Spalevic, Austin-Asomeji Iyingiala, Raheem Waliyat Bukola, Lizny Jaufer, Talib E. Butt

Turkish Journal of Agriculture and Forestry

Agriculture encompasses both plant growing (agronomy, horticulture, and forestry) and animal husbandry. Aquaculture is the aquatic embodiment of agriculture. Lagoons are the main sources of aquaculture in various countries around the world which especially yield shrimp, finfish, macrophytes, and mollusk. Agricultural effluents are highly affecting the lagoon water quality parameters in Sri Lanka since most of the agricultural farmlands in the country are on coastal landmasses. It leads to the increased risks of lagoon water contamination. Therefore, it is essential to identify the water quality parameters affected by anthropogenic agricultural activities and establish their threshold limits for ensuring the sustainability …

Genetic Diversity, Heritability, Correlation Coefficient, And Path Analysis Of Forage Yield Components In Iranian Phalaris Aquatica L. Genotypes, Reza Mohammadi, Alireza Pourmohammad, Mohammad Bagher Hassanpouraghdam, Serap Di̇ler

Turkish Journal of Agriculture and Forestry

Twenty-six selected genotypes of Phalaris aquatica L. from Iranian germplasm were evaluated to evaluate the genetic diversity of some agromorphological characteristics. Each selected genotype was cloned and planted as spaced single plants according to a randomized complete block design (RCBD) with four replications in 2016 and 2017. Large and significant (p < 0.01) differences among genotypes were found for all traits. The estimates of broad sense heritability were low to high (h$^{2}$$_{b}$ = 0.16 - 0.75) for studied traits. High heritability estimates for dry matter yield (DMY) indicate a sufficient genetic variability for further improvement. There was the highest heritability rate and genetic advance for plant height and DMY. Selection for traits with high heritability and genetic advance can be successful. The dry matter yield cut 1 (DMY1) correlation with the number of days to flowering, number of days to pollination, plant height, and crown diameter cut 2 was positive and significant. In stepwise multiple linear regression, the plant height, number of stems per plant, and spike length explained more than 84% of the total variation of DMY1. The plant height was the most crucial component of DMY1. The path analysis showed that plant height positively affected DMY1 (0.83). The highest negative indirect effects on DMY1 were observed for plant height via the number of stems per plant (-0.238). Axes 1 and 2 of the principal coordinate analysis explained 40.94% and 18.48% of the variation, respectively, and, although not entirely separated, general groupings can be determined. In factor analysis, component 1 was positively associated with the traits dry matter yield cut 2 (DMY2) (0.855), dry matter yield (0.821), and plant height (0.755). Therefore, the first component can be called the biomass component. Finally, selection would be more effective in improving forage yield based on yield components. In conclusion, the results indicated appropriate genetic variability in the studied genotypes. However, the studied genotypes will deliver a valuable germplasm to employ in breeding programs for forage cultivar production. This progress is crucial in introducing these selected genotypes to develop a core collection of Phalaris aquatica germplasm in Iran.
