Effects Of Soybean Cultivars And Planting Dates On Biomass Production, Aslam Tawhid

Masters Theses & Specialist Projects

Soybean [Glycine max (L.) Merr.] is a valuable source of edible food and organic nitrogen. Soybean cultivar development and cultural practices have been directed toward seed production rather than forage or green manure production. Recent environmental concerns have resulted in renewed interest in the use of organic matter in agriculture. The objective of the present investigation was to determine the effects of cultivar maturity differences and planting dates on biomass production of soybean. The research was conducted on the Western Kentucky University Farm in 1993. The experimental design was a split-split-plot with four replications. The three planting dates (June 2, …

Oats As A Companion Crop For Alfalfa: Establishment Methods, Shannon Hurley

Masters Theses & Specialist Projects

Companion crops are commomly seeded with alfalfa in the spring as an establishment method. The objectives of this research were to evaluate the performance of seedling Alfalfa (Medicago sativa L.) in terms of yield when grown with spring oats (Avena sativa) as a companion crop and to evaluate the amount of weed control in the alfalfa companion crop seeding, under various management practices. Six establishment treatments were imposed: (1) solo-seeded alfalfa raised according to standard procedures recommended for Kentucky, (2) solo-seeded alfalfa with a herbicide treatment, (3) alfalfa seeded with an oat companion crop and treated with a herbicide, (4) …

On-Farm Testing Of Early Maturing Soybeans, Larry J. Grabau, Colleen C. Steele, N. Gift

Agronomy Notes

Maturity Group (MG) II soybean varieties have performed well in University of Kentucky tests over the past several years. Six tests from 1986 to 1989 showed MG II varieities to outyield MG I, III, or IV varieties. During those relatively dry years, MG II may have been able to better utilize limited soil moisture than did later maturing varieties. Across the years 1990 to 1993, four planting date tests showed continued strong performance by MG II' varieties, although MG III and IV varieties had slightly higher yield averages during those wetter years. In summary, over the last eight years of …

An Evaluation Of Twelve Maturity Group Ii Soybean Varieties At Lexington, Kentucky, Larry J. Grabau, Colleen C. Steele

Agronomy Notes

In 1993, an on-farm study funded. by the Kentucky Soybean Promotion Board showed that the best Maturity Group (MG) II variety tested was quite competitive with the best available MG IV variety. However, other MG II varieties did not fare as well, indicating that careful variety selection will be essential for on-farm success with this MG II cropping system. MG II varieties used in past University of Kentucky tests have been chosen based on their performance in university variety trials where they are normally grown, for example, in Iowa, Illinois, Indiana, and Ohio. Such tests include relatively large numbers of …

Crude Protein Of Hybrid Corn Varieties Evaluated In The Kentucky Hybrid Corn Performance Tests From 1990 To 1993, C. G. Poneleit, K. O. Evans, Michael Collins, Gary L. Cromwell

Agronomy Notes

Grain samples have been collected each year since 1990 from three locations of the Kentucky Hybrid Corn Performance Test and analyzed for crude protein. The objective was to provide an unbiased comparative evaluation of the crude protein content of corn hybrids sold in Kentucky. The results indicate that while management and environment at each test 1ocat i on may have significant influences, crude protein does differ among hybrid genotypes. The feeding value of specific hybrid genotypes based on their protein content may have significant influence in diet formulation for non-ruminant animals owing to the amount of supplement needed to properly …

Wetlands: Mechanisms For Treating Acid Mine Drainage, David C. Ditsch, Anastasios D. Karathanasis

Agronomy Notes

A great deal of attention has been given to wetlands in recent years. Research suggests that natural and/or constructed wetlands may play a valuable role in flood flow moderation, sediment retention and stabilization, and waste water treatment while providing habitat for game and nongame wildlife. Only within the last 10 years have wetlands received serious attention in the treatment of acid mine drainage (AMD).

Models For Predicting The Lower Limit Of The Canopy-Air Temperature Difference Of Two Cool Season Grasses, Dennis L. Martin, David J. Wehner, C. S. Throssell

Office of the Dean (CAFES) Scholarship

Estimation of the lower limit of the canopy-air temperature differential, (T_c–T_a)_LL, is required for calculation of an empirically-based crop water stress, index. This research determined the complexity of model needed for accurate estimation of (T_c–T_a)_LL for several field grown cultivars of Kentucky bluegrass (Poa pratensis L.) and for creeping bentgrass (Agrostis stolonifera L. var. palustris (Huds.) Farw.). Regression models using vapor pressure deficit of the air (VPD), net radiation load (R_n), and wind speed (WS) were developed for predicting (T_c–T_{a …}

Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest

Journal of the Department of Agriculture, Western Australia, Series 4

Breeding new varieties of barley or other cereal crops usually takes between 12 and 15 years. five years of that time may be needed to stabalise the new varieties so that they breed trueto type, but anther culture can reduce this delay to only eight months. This technology will allow the Department of Agriculture's barley breeding programme to respond more rapidly to changes in goals set by industry and to meet market demands.

1994 Kentucky Bluegrass Variety Test Report, L. M. Lauriault, A. J. Powell, Jimmy C. Henning, Paul B. Burrus Ii, Paul C. Vincelli, Timothy D. Phillips

Agronomy Notes

Kentucky bluegrass (Poapratensis) is the third most prominent cool-season grass used in Kentucky for forage, behind tall fescue and orchardgrass. As with all cool-season grasses, Kentucky bluegrass does best in cooler weather, becoming relatively non-productive in hot, dry conditions. It is a high quality, long-lived, rhizomatous grass that is used for both turf and forage. Compared to other cool-season grasses, Kentucky bluegrass is slower to germinate (2-3 weeks) and generally is lower in seedling vigor and herbage yield. Most recent varieties have been developed for turf use. Several have been used in horse pastures even though they were …

Using Poultry Manure From Layers As A Supplemental Nitrogen Source For Corn, Lloyd W. Murdock, R. Darrell Simpson, Tim Gray

Agronomy Notes

Agronomy Notes

Kentucky bluegrass (Poa pratensis) is the third most prominent cool-season grass used in Kentucky for, forage, behind tall fescue and orchardgrass. As with all cool-season grasses, Kentucky bluegrass does best in cooler weather, becoming dormant in hot, dry conditions. It is a high quality, long-lived, rhizomatous grass that is used for both turf and forage. Compared to other cool-season grasses, Kentucky bluegrass is slower to germinate (2-3 weeks) and generally is lower in seedling vigor and herbage yield. Most recent varieties of Kentucky bluegrass have been developed for turf use; therefore, primary emphasis has been placed on improving …

Alley Farming : New Vision For Western Australian Farmland, Ted Lefroy, Phil Scott

Journal of the Department of Agriculture, Western Australia, Series 4

Alley farming is a system where crops and pastures are grown in the alleys between rows of trees and shrubs. The concept is new to Western Australia but one that is likely to become more familiar over the next few years. The objective is to use trees and shrubs to decrease the environmental side effects of agriculture, such as erosion and salinity while increasing farm profit through the direct and indirect value of the trees.

This article describes some examples of alley farming in Western Australia and discusses the challenge of getting the right tree species and layout to maximise …

Lupin Stubbles : Getting The Best With Weaner Sheep, Keith Croker, Colin Mcdonald, Jeremy Allen

Journal of the Department of Agriculture, Western Australia, Series 4

Sweet lupins are now grown on about a million hectares in Western Australia each year. If half of the State's seven million weaners were grazed as recommended on half of the lupin stubbles, it could generate about $15 million from reduced supplementary feeding, greater wool production and other advantages. But correct management is important, particularly knowing when to take weaners out. Research by the Department over the last five years is now indicating how this should be done.

Using Hydrophilic Polymers To Control Nutrient Release, Robert Mikkelsen

Robert Mikkelsen

Using diverse technological approaches, many types of delivery devices have been used to supply plant nutrients at a controlled rate in the soil. One new approach is the use of hydrophilic polymers as carriers of plant nutrients. These polymers may be generally classified as 1) natural polymers derived from polysaccharides, 2) semi-synthetic polymers (primarily cellulose derivatives), and 3) synthetic polymers. By controlling the reaction conditions when forming the polymers, various degrees of cross-linking, anionic charge, and cationic charge can be added, thereby changing their effectiveness as fertilizer carriers. When fertilizer-containing solutions are mixed with hydrophilic polymers to form a "gel" …
