Strawberry Growth, Yield, Fruit Nutrition, And Control Of Verticillium Wilt With Pre-Plant Soil Fumigants, Ozone, And Biological Control, Justin J. Scurich

Master's Theses

Verticillium wilt is a widespread soilborne disease of strawberry historically controlled by soil fumigation with methyl bromide (MB). MB was banned by the United Nations in 1995 and will be completely phased out by 2015. Research has concentrated on alternative methods of disease control without finding a single alternative able to replace MB in widespread disease control and yield increase. For the current study, strawberries were greenhouse grown in container pots filled with soil from both infested and non-infested areas of a commercial strawberry field in Watsonville, CA. Treatments included pre-plant soil fumigation with commercially available formulations of methyl bromide, …

Oviposition Induced Volatile Emissions From African Smallholder Farmers' Maize Varieties, Amanuel Tamiru, Toby J.A. Bruce, Charles A.O. Midega, Christine M. Woodcock, Michael A. Birkett, John A. Pickett, Zeyaur R. Khan

All Peer-Reviewed Publications

Maize (corn), Zea mays, is a genetically diverse crop, and we have recently shown that certain open pollinated varieties (OPVs) of Latin American origin possess a trait not present in mainstream commercial varieties: they produce volatiles in response to stemborer oviposition that are attractive to stemborer parasitoids. Here, we tested whether a similar tritrophic effect occurs in the African OPVs 'Nyamula' and 'Jowi'. Herbivore induced plant volatiles (HIPVs) were collected from plants exposed to egg deposition by the stemborer Chilo partellus. In a four-arm olfactometer bioassay, the parasitic wasp Cotesia sesamiae preferred samples containing HIPVs from plants with eggs to …

Supersweet Sweet Corn Cultivar Evaluation For Northern Indiana, 2011, Elizabeth Maynard

Midwest Vegetable Trial Reports

Indiana growers harvested sweet corn for fresh market sales from 6,500 acres in 2010, with an average yield of 92 cwt/acre (219 crates or 4.6 tons per acre) and total value of $14.4 million (USDA NASS, 2011). Indiana ranks 13th among states for production of fresh market sweet corn. The 2007 USDA Ag Census reported 603 Indiana farms producing sweet corn for fresh markets and 51 farms selling to processors. Sweet corn fields for fresh market sales are located throughout the state. In northern Indiana, bicolor corn is most commonly grown. Varieties with improved eating quality are of interest to …

Arkansas Cotton Variety Test 2011, Fred M. Bourland, A. B. Beach, D. P. Roberts Jr.

Arkansas Agricultural Experiment Station Research Series

The primary goal of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed companies establish marketing strategies and assists producers in choosing varieties to plant.

2011 Vadose Zone Nitrate Study At Hastings, Ne (Revised), Roy F. Spalding, Martin Toavs

Department of Agronomy and Horticulture: Faculty Publications

In an effort to assist Hastings Utilities in the management of their well-head protection area (WHP A) and to protect the groundwater from the impact of nitrate loading from potential nonpoint and point sources, Hastings Utilities subcontracted with the Department of Agronomy and Horticulture at the University of Nebraska for deep vadose zone coring. Continuous 60-ft soil cores were obtained at 36 sites within the apparent WHP A (Figure 1). The sites were selected by Marty Stange on the basis of availability for sampling, management, landuse , cropping history, and location within the WHPA. Nitrogen analyses of these deep soil …

Genome-Wide Analysis Of Syntenic Gene Deletion In The Grasses, James C. Schnable, Michael Freeling, Eric Lyons

Department of Agronomy and Horticulture: Faculty Publications

The grasses, Poaceae, are one of the largest and most successful angiosperm families. Like many radiations of flowering plants, the divergence of the major grass lineages was preceded by a whole-genome duplication (WGD), although these events are not rare for flowering plants. By combining identification of syntenic gene blocks with measures of gene pair divergence and different frequencies of ancient gene loss, we have separated the two subgenomes present in modern grasses. Reciprocal loss of duplicated genes or genomic regions has been hypothesized to reproductively isolate populations and, thus, speciation. However, in contrast to previous studies in yeast and teleost …

Cambio Climático Reduciría Cultivos: El País Vería Una Baja De Entre Un 20% Y 50% En El Rendimiento Del Frijol, Maíz Y Sorgo, Por El Incremento En Las Temperaturas, Según Un Informe De La Universidad Estatal De Kansas, Rosa María Pastrán

INTSORMIL Impacts and Bulletins

El aumento de la temperatura que se producirá en los próximos 50 años, a consecuencia del cambio climático, provocaría una reducción en la producción de granos básicos en El Salvador, según un estudio del Departamento de Agronomía de la Universidad Estatal de Kansas, Estados Unidos.

En el caso de El Salvador, la investigación encontró que la temperatura actual incrementará entre 3 y 5 grados centígrados (°C). Este aumento afectará, de manera progresiva, el rendimiento de cultivos como frijol, maíz y sorgo, de acuerdo con lo que explicó el profesor Vara Prasad, quien presentó el estudio en el país.

What Is Forest Farming?

Working Trees (USDA-NAC)

What is forest farming?

Forest farming, or multi-story cropping, is a distinctive approach to land management that combines management practices of conventional forestry with those of small-scale farming or gardening to attain an environmentally and economically sustainable land-use system.

Typically, a forest farming system is established by thinning an existing woodland or plantation to leave the best canopy trees for continued timber production and to create the appropriate conditions that favor the understory crop.
