Genetic Diversity In Cowpea [Vigna Unguiculata (L.) Walp.] As Revealed By Rapd Markers, Fana Sylla Ba, Remy S. Pasquet, Paul Gepts

All Peer-Reviewed Publications

The present study, using RAPD analysis, was undertaken to characterize genetic variation in domesticated cowpea and its wild progenitor, as well as their relationships. The materials used consisted of 26 domesticated accessions, including accessions from each of the five cultivar-group, and 30 wild/weedy accessions, including accessions from West, East and southern Africa. A total of 28 primers generated 202 RAPD bands. One hundred and eight bands were polymorphic among the domesticated compared to 181 among wild/weedy cowpea accessions. Wild accessions were more diverse in East Africa, which is the likely area of origin of V. unguiculata var. spontanea. Var. spontanea …

Moisture Potential Affects Rate Of Leaf Appearance In Cool Season Grasses, Nina Cherone Terrell

McCabe Thesis Collection

The rate of leaf appearance and onset of growth in cool season grasses may be influenced by soil moisture potential and exposure to below freezing temperatures. Levels of moisture potential and days exposed to freezing temperatures, which will restrict leaf appearance, are not well defined. The first part of this study was to determine the effects of different moisture potentials on the leaf appearance rates in two cool season grasses. Italian ryegrass (IRG) and tall wheat grass (TWG) were grown hydroponically at 4 moisture potentials in seed pouches in an incubator under a photoperiod of 13 hours light and 11 …

The Influence Of Environmental Temperature And Substrate Initial Moisture Content On Aspergillus Niger Growth And Phytase Production In Solid−State Cultivation, Seaborn B. Carter, Sue E. Nokes, Czarena L. Crofcheck

Biosystems and Agricultural Engineering Faculty Publications

Aspergillus niger is being used commercially for phytase production utilizing solid-state cultivation; however, no studies have been published that investigated the optimal environmental temperature and initial substrate water content to maximize fungal growth and/or phytase production. Solid-state cultivations of Aspergillus niger on wheat bran and soybean meal were conducted at three temperatures (25°C, 30°C, and 35°C) and three initial moisture contents (50%, 55%, and 60% wet basis) in a split-plot full-factorial experimental design. Fermentations were conducted for 0, 24, 48, 72, and 120 h. The containers were sampled destructively and assayed for phytase activity and glucosamine concentration as an estimate …

Seven Basic Elements For A Successful Native Warm Season Grass Establishment For Forage Production, Randy Seymour, John Seymour

Forage Symposium at the Kentucky Cattlemen’s Convention

First, let’s make it clear from the start, there is NO justification for plowing up all of your cool season forages and replacing them with warm season forages.

We strongly believe, and can support our belief with practical evidence, that warm season native grasses, produced in DESIGNED AMOUNTS to complement cool season forages, will make money for the beef and dairy producer.

Managing Broomsedge In Pastures, Monroe Rasnake

Forage Symposium at the Kentucky Cattlemen’s Convention

Broomsedge, broomgrass, sagegrass (Andropogon Virginiana) is a perennial, warm season grass native to Kentucky. It is well adapted to the soils and climate of this area. Add to this the fact that it is relatively unpalatable to livestock and it is easy to understand why it is common in Kentucky pasture fields. The question then becomes: why is it a problem in some fields and not in others?

Getting More From Forages, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

In human endeavors, results are usually highly correlated with investments in terms of thought, time, effort, and a certain amount of money. In particular, the best and most profitable forage programs have had the most thought put into them. Top producers strive to continue to improve their operations by developing strategies, practices, and procedures that will result in “GETTING MORE FROM FORAGES”.

Crop Performance And Soil Properties Of Sites Previously Used For Production Of Beef Cattle Manure Compost, Daniel Ginting, Bahman Eghball, Daniel T. Walters, Charles A. Francis, Terry J. Klopfenstein, Casey Wilson, Galen E. Erickson

Nebraska Beef Cattle Reports

This study was established on sites that had three or seven years of compost production history. Corn, wheat, barley, sorghum and alfalfa were planted in 2001. In the first year, wheat, barley and sorghum performed better than corn in the windrow areas while alfalfa did not even establish because of excessive salt in the soil. Soil electrical conductivity, K and Na in the 0-6 inch depth under windrows were high and caused soil crusting and poor germination and crop yields. Growing salt tolerant crops, such as barley, can rehabilitate sites used for composting and the process can be accelerated by …

Fisheries Research Contract Report No. 6 - Assessment Of The Nutritional Variability Of Lupins As An Aquaculture Feed Ingredient, Brett Glencross, John Curnow, Wayne Hawkins

Fisheries Research Reports

The nutritional value of the kernel meals of three species of lupin (Lupinus albus, L. angustifolius and L. luteus) was compared against each other and a reference ingredient of solvent extracted soybean meal, when fed to rainbow trout (Oncorhynchus mykiss). Each lupin kernel meal was included in test diets at 300 g/kg and also at a greater level, representing 50% of the total protein content in the diet. The digestibility of protein of all lupin kernel meals was better than for the soybean meal. The highest protein digestibility was that from L. luteus kernel meal at 30% inclusion (100%), which …

Comparison Of Native Brushland, Replanted, And Unaided Secondary Succession Plant Communities In The Lower Rio Grande Valley Of Texas, Mitchell Allen Sternberg

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Agriculture and urban development have destroyed 95% of native brushland habitat in the Lower Rio Grande Valley (LRGV) of south Texas. Therefore, habitat restoration is an important issue in the LRGV. Since 1982, the U.S. Fish and Wildlife Service has been replanting areas in the LRGV to native brushland species to establish a wildlife corridor along the lower reach of the Rio Grande. Vegetation composition of a mature brushland, a replanted habitat and an unaided secondary succession site (fallow field) were examined at one locale in the LRGV in 1999. The mature brushland edge plot had the highest species richness …
