The driver of agricultural development is the introduction of new technology. Sensitive sorghums have long been a critical component of hillside Central American agriculture providing a reserve or insurance policy when the principal staple of maize falters. The insensitive sorghums have been more recently introduced since the ‘70s for planting in the valleys in the second season. In the last thirty years the introduction of new insensitive cultivars has accelerated initially for poultry and in the previous two decades for dairy production. This growth has been facilitated by strategic investments in research by CENTA and the Ministry of Agriculture.

Diversification Or Cotton Recovery In The Malian Cotton Zone: Effects On Households And Women, Jeanne Yekeleya Coulibaly
INTSORMIL Scientific Publications
This dissertation investigates income diversification alternatives from the cotton economy and compares those initiatives with present policy measures to restore the cotton sector in Mali. It also derives the welfare implications for women of these various policy measures.
During the decade preceding 2011, farmers’ incomes in the cotton zone of Mali have been significantly affected by the downturn of the cotton economy explained by many factors including the low farm gate cotton price, the declining cotton yields and soil fertility concerns. In 2011, the Malian government substantially increased the farm gate cotton price as a result of the world cotton …

Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. A genome-wide profiling of DNA methylation in two different genotypes of Zea mays (ssp. mays), an organism with a complex genome of interspersed genes and repetitive elements, allowed the identification and characterization of examples of natural epigenetic variation. The distribution of DNA methylation …

Effects Of Soil And Foliar Applications Of Zinc On Grain Zinc Concentrations Of Maize, Sorghum And Wheat In Zambia, Obed I. Lungu, S. Simunji, I. Cakmak
INTSORMIL Scientific Publications
Micronutrient deficiencies are quite widespread in Sub‐Saharan Africa including Zambia. A survey study of selenium and zinc content in selected soils and staple food crops showed low concentrations that suggested that populations might be at risk of low intake of these micronutrients through the diet. The beneficial effects of Se and Zn are well documented in human populations (Black et al. 2008). Agronomic bio‐fortification offers a promising strategy to address micronutrient deficiency in the diet (Cakmak, 2008). This study was conducted to evaluate the effects of soil and foliar applications of Zn on Zn concentrations in maize, sorghum and wheat.

Biological Sciences Faculty Research
Effects of soil freezing on nitrogen (N) mineralization have been the subject of increased attention in the ecological literature, though fewer studies have examined N mineralization responses to successive mild freezing, severe freezing and cyclic freeze–thaw events. Even less is known about relationships of responses to soil N status. This study measured soil N mineralization and nitrification in the field along an experimental N gradient in a grassland of northern China during the dormant season (October 2005–April 2006), a period in which freezing naturally occurs. Net N mineralization exhibited great temporal variability, with nitrification being the predominant N transformation process. …

Gata-Family Transcription Factors In Magnaporthe Oryzae, Cristian F. Quispe
Gata-Family Transcription Factors In Magnaporthe Oryzae, Cristian F. Quispe
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The filamentous fungus, Magnaporthe oryzae, responsible for blast rice disease, destroys around 10-30% of the rice crop annually. Infection begins when the specialized infection structure, the appressorium, generates enormous internal turgor pressure through the accumulation of glycerol. This turgor acts on a penetration peg emerging at the base of the cell, causing it to breach the leaf surface allowing its infection.
The enzyme trehalose-6- phosphate synthase (Tps1) is a central regulator of the transition from appressorium development to infectious hyphal growth. In the first chapter we show that initiation of rice blast disease requires a regulatory mechanism involving an …

Transpiration-Use Efficiency Coefficient Of Seven Weed Species As Affected By Fraction Of Transpirable Soil Water And Growth Stage, Venkatarao Mannam
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Transpiration-use efficiency coefficient (Kc) describes the amount of biomass produced per unit transpiration at a given vapor pressure deficit. A series of greenhouse experiments were conducted to determine the Kc values of seven weed species and to measure how Kc values were affected by fraction of transpirable soil water (FTSW) level and plant growth stage. Experiments were conducted using a factorial design with 4 levels of water stress (0.3, 0.4, 0.7, and 1.0 FTSW) and two harvest times (first bloom and seed maturity). After plants attained a predetermined size, each plant was sealed at the base using a …

Herbicide-Resistant Risk Assessment: Response Of Common Nebraska Weeds To Dicamba Dose, Roberto J. Crespo
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Dicamba-resistant soybeans are being developed to provide an additional herbicide mechanism of action that can be used in soybean, and to provide a tool to help manage or mitigate the evolution of other herbicide-resistant weed populations. The objectives of this thesis were to assess the risk of common Nebraska weeds developing resistance to dicamba, quantify baseline dose-response to dicamba of high-risk weed species, and survey the variability in dicamba dose-response among populations of those species. Twenty-five weed scientists were asked to estimate the risk likelihood of ten weed species evolving resistance to dicamba following the commercialization of dicamba-resistant soybean. Palmer …

Biology, Systematics, Phylogenetic Analysis And Dna Character-Based Species Diagnosis Of The False Root-Knot Nematode Nacobbus Aberrans (Thorne, 1935) Thorne & Allen 1944 (Nemata:Pratylenchidae), Angel Ramirez-Suarez
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The False Root-Knot nematode Nacobbus aberrans is a plant parasitic nematode that causes yield losses in several crops and plant protection agencies have established regulations to prevent infestations from spreading to new agricultural areas. The taxonomic status of the nematode has been the subject of controversy due to wide degree of variation exhibited by the species. This variability has led to the suggestion that N. aberrans is actually a species complex rather than a single species. In order to test this hypothesis, we compared twelve N. aberrans populations, which include isolates from western Nebraska, two distinct regions of Mexico and …
Information To Action: Providing Management Recommendations To Agricultural Users Affected By Drought, Bruce Erickson
Information To Action: Providing Management Recommendations To Agricultural Users Affected By Drought, Bruce Erickson
2011 Symposium on Data-Driven Approaches to Droughts
Mitigating drought’s impact on agricultural production is a key part of any food security and economic stabilization plan. While most agricultural producers periodically experience abnormally dry periods that sometimes limit production, extreme or exceptional droughts may occur infrequently enough that management strategies are unfamiliar, outdated, or untested in a particular set of circumstances. While information to spatially delineate and characterize the effects of a drought is important, the real payoff comes from providing drought-affected individuals with recommendations on how to best manage their situation, and for them to actually adopt these practices. In crop production the ramifications are many: decisions …
