Common Waterhemp Growth And Fecundity As Influenced By Emergence Date And Competing Crop, E. Uscanga-Mortera, S. Clay, F. Forcella, J. Gunsolus

Agronomy, Horticulture and Plant Science Faculty Publications

Common waterhemp (Amarathus rudis Sauer) is a frequent weed in glyphosate-resistant (GR) crops in the midwestern USA due, in part, to the delayed emergence of its seedlings. Variable waterhemp emergence was simulated by transplanting seedlings into both corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] and bare plot areas at differing crop growth stages during two growing seasons in western Minnesota. Growth and fecundity were measured. As expected, late planted weeds produced little dry matter and few seeds, and competition from corn or soybean reduced waterhemp dry weight and fecundity by 90% compared with isolated plants. Interestingly, common …

Organic Apples A Production Guide, Steven Mccoy

Bulletins 4000 -

The belief among some conventional apple growers that it is not possible to reliably produce profitable yields of good quality apples under an organic system in Western Australia is being reconsidered. There are now very good examples of successful commercial organic apple orchards in many parts of the world, including WA. The organic production systems developed by these dedicated growers are showing that yields and quality are comparable to conventional systems.

Uno de los problemas que más acosa el desarollo de la industria lechera en Centro América es la falta de forraje de buena calidad, lo cual se traduce en baja producción tanto de leche como de carne y en aumento en los costos de producción. Muchos ganaderos productores de leche, en su búsqueda por un adecuado forraje para alimentar el hato de vacas, utilizan híbridos de sorgo o maíz de baja calidad lo cual resulta en pérdidas económicas.

En el caso del sorgo, el mayor problema es la falta de cultivares que tengan los siguientes atributos 1) sean tempranos, 2) …

Centa Ss- 44, New Sorghum Forage Hybrid For El Salvador, Intsormil

INTSORMIL Impacts and Bulletins

One of the major problems plaguing the development of the Central American dairy industry is the lack of good quality forage which results in low milk and meat production and an increase in production costs. Many dairy farmers, in their search for suitable forage to feed their cattle herds, utilize poor quality sorghum or maize hybrids which can result in economic losses.

In the case of sorghum, the major problem is a lack of cultivars that (1) are early, (2) grow rapidly, (3) are of proper plant height, (4) are resistant to diseases, (5) have high yield potential and (6) …

Biosystems and Agricultural Engineering Faculty Publications

Corn stover has been identified as a potential feedstock for the production of fermentable sugars and thermochemical processes. The availability and efficiency of typical hay equipment for collecting corn stover has not been well quantified. Corn stover was collected for two years on a central Kentucky farm near Louisville. Six different harvesting treatments, using traditional hay equipment, were used to harvest corn stover. A rotary mower, rotary scythe (flail-type mower with windrow-forming shields), parallel bar rake, and a round baler were utilized. The average stover moisture content prior to grain harvest was above 40%, and field drying was required before …

Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Freedom-To-Operate In The Crop Sciences: Procedure, Stanley P. Kowalski

Law Faculty Scholarship

Freedom to operate (FTO) is the ability to proceed with research, development and commercialization of a crop science product, while fully accounting for any potential risks of infringing activity, that is, whether a product can be made, used, sold, offered for sale, or exported, with a minimal risk of infringing the unlicensed intellectual property rights (IPRs) or tangible property rights (TPRs) of another. An FTO analysis begins with the ‘FTO team’ systematically dissecting the crop science product into the components, combination of components, processes and germplasm that went into its research and development. This is followed by generating a series …

Sorghum: A Substitute For Maize In The West Africa Poultry Industry, Intsormil

INTSORMIL Impacts and Bulletins

With the declining relative prices of chicken compared with other meats, poultry consumption per capita in the USA has been increasing, while that of other meats has been stagnant or declining. Similar developments are occurring in West Africa.

There is interest in substituting sorghum for maize in poultry rations, in the U.S. and in West Africa, for both broiler and egg production. In contrast to maize, which is a thirsty plant and requires large amounts of water, sorghum offers farmers the ability to grow a crop where other crops do not produce well. In Niger, West Africa, locally produced sorghum …
