Soil Test And Phosphorus Rate For High Rainfall Clover Pastures, Robert Summers, David Weaver

Bulletins 4000 -

When new land was first developed, phosphatic fertilisers had to be applied at high rates to overcome Phosphorus (P) deficiency, and to increase P fertility. Once good P fertility has been established after a number of years of applying P, the requirement for applying high rates of P falls. After that you only need to apply enough fertiliser P to replace that removed in products, fixed by the soil, eroded and leached, that is a maintenance rate of P.

In relation to P fertiliser decisions for pastures you need to ask:

• Do I need P?

• How do I …

Analysis Of Rice Blast Resistance Genes In The National Small Grains Collection (Nsgc), Moytri Roychowdhury

Graduate Theses and Dissertations

Identification of blast resistance genes in rice germplasm is one of the most important activities of rice breeding programs in worldwide. The objective of this research was to characterize two major blast resistance genes, Pi-z and Pi-b, in selected rice germplasm. A simple sequence repeat DNA marker, AP5659-1 linked to the Pi-z gene, and a Pib dominant marker derived from the Pi-b gene were first used to screen a rice core collection consisting of 1700 accessions estimated to represent 70% of the genetic diversity of rice in the US National Small Grains Collection. There were 131 rice germplasm accessions with …

Sorghum Clear Beer Value Chain, Bernadette C. Chimai

INTSORMIL Presentations

The markets and industrial utilization of agricultural commodities have undergone considerable change in the last few decades.

In Zambia, sorghum was considered a traditional crop with limited industrial uses.

Research and transformations in consumer tastes and preferences have led to the development of new uses for sorghum.

Potential markets for industrial utilization of sorghum have been identified as food processing, beer brewing, feed concentrates and energy production.

One of the success stories in industrial utilization of sorghum has been Eagle, a sorghum based clear beer produced by Zambian breweries.

The study reported in this paper aims to examine the main …

Antioxidant And Antihypertensive Activities Of Rice Bran Peptides, Janika Hull, Arvind Kannan, Navam S. Hettiarachchy

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Protein isolates and peptide fractions from food sources (cereal grains), have been shown to exert bioactive properties including antiobesity, anticancer, antiangiogenic, etc. One such food source is rice bran, which is an underutilized co-product of rough rice milling. It contains 90% of the nutrients and nutraceuticals of value to health, including high quality protein. The high quality protein is a potential source to generate peptides that can reduce hypertension and oxidative stress, both being important risk factors for cardiovascular diseases. The objective of this study was to extract peptide hydrolysates from heat stabilized defatted rice bran by enzymatic hydrolysis, evaluate …

Storage Effects Of Gel Encapsulation On Stability Of Chokeberry Monomeric Anthocyanins, Procyanidins, Color Density, And Percent Polymeric Color, Mary Kordsmeier, Luke Howard

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Chokeberries (Aronia melanocarpa) are an antioxidant-rich plant product due to their high content of polyphenols, especially anthocyanins and procyanidins. These polyphenols have been shown to provide protection against coronary heart disease, stroke, and lung cancer, as well as against oxidative stress, the main cause behind chronic diseases promoted by free radicals. The objective of this study was to determine the storage effects of gelatin encapsulation on monomeric anthocyanins, procyanidins, color density, and percent polymeric color of three gummy candies of different strengths formulated with a base of 25.4% chokeberry concentrate, 47.6% sucrose, 1.3% Splenda, and 0.025% potassium sorbate.

Properties Of Gluten-Free Pasta Prepared From Rice And Different Starches, Alexandria W. Mertz, Ya-Jane Wang

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Rice is one of the few cereal products that does not contain gluten. However, the absence of gluten poses problems in the structure of and cooking quality of rice pasta. The objective of this project was to investigate the addition of starch on the physicochemical properties and cooking quality of rice-based pasta. Rice-based pasta was prepared from parboiled long-grain rice flour with the addition of 25% cooked starch from different sources. The color and pasting properties of the ground pasta flour were measured by a chroma meter and a Rapid Visco Analyser, respectively. The pasta was cooked to the optimum …

Also explains the science of malting, and the importance of using high-quality grain.

Eagle Lager: A Sorghum Success Story On Many Levels, Ian Mackintosh

INTSORMIL Presentations

In 1999 in Uganda we were faced with a static but highly competitive market.

Needed to grow our market and to do this we needed to make beer cheaper

It was felt that a suitable local ingredient would reduce the cost of manufacture and stimulate local agriculture and the economy as well as provide opportunities for growth and profit for the company.

An extensive base line study of the Ugandan agricultural sector was undertaken to determine what was “out there.”

It was clear that there was enormous potential but little else.

Sorghum seemed the logical starting point because there was …
