The Effect Of Two Different Harvesting Methods On The Yield Of 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) When Grown In A Wiregrass Tunnel House, Veronica E. Walton, Raymon Shange, Melissa Johnson, Edward Sparks, Victor Khan, James E. Currington, Ramble Ankumah, Nathaniel Ellison, George X. Hunter Jr., Jeffery L. Moore

Professional Agricultural Workers Journal

A study was conducted to determine if 100% or 50% harvesting of collard leaves was a suitable recommendation for Tunnel House producers. The experiment was conducted as a split-split plot design with varieties as the main plots, harvesting 100% or 50% of leaves as the sub-plots, and days after transplanting as the subplots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between varieties and method of harvest, for leaf numbers and weight. Conversely, the varieties showed significant differences for yield but not leaf numbers. Both varieties showed significant …

The Evaluation Of Two Different Harvesting 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) Leaves From Plants Grown In A Wiregrass Tunnel House, Edward Sparks, Raymon Shange, Jacquelyn Jackson, Victor Khan, James E.

Professional Agricultural Workers Journal

A study was conducted to determine if a 100% or 50% harvest intensity of ‘Topbunch’ collards leaves could be a recommended practice for Tunnel House producers. The experiment was conducted as a split-plot design with harvest dates as main plots, and harvesting intensity of 100% or 50% of leaves as sub-plots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between harvest methods and dates for number and weight of leaves harvested. There were also significant differences for the weight of leaves harvested and numbers. The leaf recovery rates …

The Dinosauria: Baraminological And Multivariate Patterns, Neal A. Doran, Matthew Mclain, Natalie Young, Adam Sanderson

Proceedings of the International Conference on Creationism

The Dinosauria pose both interesting and challenging questions for creationist systematists. One question is whether new dinosaur discoveries are closing morphospatial gaps between dinosaurian groups, revealing continuous morphological fossil series, such as between coelurosaurians and avialans. Questions such as these underscore the importance of systematics for resolving correct group memberships, including tools for visualizing morphospatial relationships. Baraminic distance correlation (BDC), three-dimensional multidimensional scaling (MDS), and a new method to baraminic studies – principal component analysis (PCA) – were applied to 18 character matrices from 2004. The data included saurischian and ornithischian dinosaur groups including (1) “basal” Saurischia, (2) Ceratosauria (including …

Old And Recent Processes In A Warm And Humid Desert Hypogene Cave: ‘A’Rak Na‘Asane, Israel, Amos Frumkin, Shlomi Aharon, Uri Davidovich, Boaz Langford, Yoav Negev, Micka Ullman, Anton Vaks, Shemesh Ya‘Aran, Boaz Zissu

International Journal of Speleology

Recent environmental processes are studied in ʻA’rak Naʻasane Cave at the northern Judean Desert, Israel. The outer zone of the cave is heavily influenced by the outside environment through a large entrance, facilitating entry of air flow, fauna and humans, with minor cave-forming modifications. Conversely, the inner cave sustains humid and warm conditions, favoring modifications by condensation corrosion of convective air flow, associated with deposition of popcorn speleothems at the lower parts of dissolution pockets. The warm humid air of the inner cave may be associated with an underlying thermal water table. Active condensation corrosion is decreasing, possibly because of …

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler

Public Land & Resources Law Review

In Hawai’i Wildlife Fund v. County of Maui, the Ninth Circuit held that the plain language of the Clean Water Act provides jurisdiction over indirect discharges of pollutants from a point source into groundwater that is shown to be connected to navigable waters. The court found that studies confirmed pollutants entering the Pacific Ocean were fairly traceable to the County of Maui’s sewage disposal wells. In affirming the district court’s ruling, the Ninth Circuit held that Maui County violated the Clean Water Act by discharging pollutants into a navigable water without the required permit. The court also concluded the …

Electrical Resistivity Tomography Of Claypan Soils In Southeastern Kansas, M. A. Mathis Ii, S. E. Tucker-Kulesza, G. F. Sassenrath

Kansas Agricultural Experiment Station Research Reports

Claypan soils cover approximately 10 million acres across several states in the central United States. The soils are characterized by a highly impermeable clay layer within the profile that impedes water flow and root growth. While some claypan soils can be productive, they must be carefully managed to avoid reductions to crop productivity due to root restrictions, water, and nutrient limitations. Clay soils are usually resistant to erosion but may exacerbate erosion of the silt-loam topsoil.

Soil production potential is the capacity of soil to produce at a given level (yield per acre). The productive capacity is tied to soil …

Exploring The Physical, Chemical And Biological Components Of Soil: Improving Soil Health For Better Productive Capacity, G. F. Sassenrath, K. Davis, A. Sassenrath-Cole, N. Riding

Kansas Agricultural Experiment Station Research Reports

“Soil health” is a term that is used to describe soil quality. The U.S. Department of Agriculture’s Natural Resources Conservation Service has defined soil health as “The continued capacity of soil to function as a vital living ecosystem that sustains plants, animals and humans (NRCS 2018).” For a farmer, soil health is the productive capacity of the soil, or the capacity of the soil to produce a crop or pasture. Healthy soils produce more and with better quality.

Soil health is critical for water and nutrient cycling. Soil captures rainwater and stores it for use by plants. Soil health is …

Soil Health Profile In Claypan Soils, C. J. Hsiao, G. F. Sassenrath, C. Rice, G. Hettiarachchi, L. Zeglin

Kansas Agricultural Experiment Station Research Reports

Healthy soil is the foundation of a sustainable agronomic production system. Microorganisms include bacteria (such as actinomycetes), fungi, and protozoa. Soil microorganisms, or microbes, exist in large numbers in soils and are critical for decomposition of organic residues and nutrient recycling. Soils with ample and diverse microbial populations can provide more essential nutrients for crop growth and development. Soil microbial properties are considered one of the major indicators of soil health.

Soil microbial properties can be measured by the activity and the composition of micro-organism populations. Phospholipid fatty acids (PLFA) are the primary components of cell membranes, they can be …
