Stratification Of Potassium And Phosphorus In Tillage Vs. No-Till Systems And Uptake In Corn (Zea Mays) In Western Kentucky, Ava Isaacs, Kyle Krieger, Christopher Powell

Scholars Week

There are 12 nutrients essential for plant growth, two of these are phosphorus and potassium. The demand and need for these nutrients are very high in agricultural systems including corn. Phosphorus stimulates root and shoot growth and is essential for seedling growth and stability. Potassium increases tolerance to water stress, as well as resistance to disease, these are both critical in terms of soil fertility and in determining what fertilizers to apply as well as the amount of fertilizer needed. Both nutrients are not readily available for plant uptake in the soil and are largely lost during harvest, which could …

Lai As Affected By Flashing-Light Interception With Corn And Soybeans, Josh W. Pohl, Jondavid Mcclanahan, Jake Eaker

LAI as Affected by Flashing-Light Interception With

Corn (Zea mays) and Soybeans (Glycine max)

Corn (Zea mays) and Soybean (Glycine max) are both staple crops in global agriculture. With growing concern regarding food security and production, indoor cultivation of corn and soybean plants has become a question of interest. This study looks at the application of different lighting regimes for corn and soybeans and effects on development. Light that can be used by plants is called photosynthetically active radiation (PAR). PAR is the solar radiation range of energy that plants use for …

Soil Properties Associated with Land Management Practices in Western Kentucky

Mentor: Dr. I.P. Handayani

Hutson School of Agriculture, Murray State University, Kentucky, USA

Abstract

One of the most important factors regarding soil and plant health is nutrient availability and fertility. Of these two factors that were mentioned available potassium is a key component. With that being said we decided that it would be beneficial to see how potassium can be traced within the soil in various locations after fertilizer is applied. There were two parts to this experiment. Part one was …

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 …

Soil Responses to One-Season Winter Cover Crops

McKenna Morgan and I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

In regions like western Kentucky where wooded lots are common there is a growing interest in how to utilize them so that land profits can be maximized. The frequently poor soils in wooded areas due to erosion and lack of ground cover vegetation often cause complications in the creation of pasture areas. Therefore, the objective of this study was to assess the effect of growing winter cover crops on soils to prepare for pasture systems in the …

Impact Of Aerobic Compost Tea On Growth Of Lactuca Sativa Within A Peat-Based Growing Media, Ella Potts, Jessica Stoner, Alyx Shultz, Iin Handayani

Posters-at-the-Capitol

Compost and compost tea have been shown in practice to be valuable soil amendments across many horticultural applications; however, little rigorous quantitative work has been completed. Researchers designed a side-by-side trial with two replications to quantifiably study the impact of compost tea on the growth and vigor of soil-grown lettuce. A recycled poultry-litter-based aerobic compost tea was used for the treatment. Six lactuca sativa plants received each treatment or control. Researchers hypothesized the treatment plants would show more vigor and vegetative growth than control. The null hypothesis was treatment plants would be identical to control lettuce. Researchers failed to reject …
