Forage Production From Perennial Vs. Annual Crop R~ On In Sandy Soils In Egypt, Z. Abdelhalim, O. Niemeläinen, I. A. Hanna, A. M. Rammah
IGC Proceedings (1977-2023)
Forage production was studied on newly reclaimed sandy soil in Egypt trom perennial lucerne (Medicago sativa L.) and two annual crop rotations. The cropping systems were: A) lucerne, B) berseem clover (Trifolium alexandrinum L.) in the winter followed by pearl millet (Pennisetum glaucum R. Br. Emend. Stantz.) in the summer and C) triticale (XX Triticosecale Wittm.) (forage cut + grain harvest) in the winter followed by maize (Zea mays L.) (grain + stover) in the summer. Mean annual dry matter yields (t ha-1 ) were 20.65, 26.59 and 27.48 from A, B and C, respectively. However, …

Impact Of Urbanization Trends On Production Of Key Staple Crops, José F. Andrade, Kenneth G. Cassman, Juan I. Rattalino Edreira, Fahmuddin Agus, Abdullahi Bala, Nanyan Deng, Patricio Grassini
Department of Agronomy and Horticulture: Faculty Publications
Urbanization has appropriated millions of hectares of cropland, and this trend will persist as cities continue to expand. We estimate the impact of this conversion as the amount of land needed elsewhere to give the same yield potential as determined by differences in climate and soil properties. Robust spatial upscaling techniques, well-validated crop simulation models, and soil, climate, and cropping system databases are employed with a focus on populous countries with high rates of land conversion. We find that converted cropland is 30–40% more productive than new cropland, which means that projection of food production potential must account for expected …

Transgenic Maize Hybrid Crop Residues: Nutritive Value And Their Effects On Performance Of Grazing Beef Cows, S. K. Barnhart, J. R. Russell, M. J. Hersom, D. E. Farnham
IGC Proceedings (1977-2023)
Several maize (Zea mays) hybrids, including three transgenic hybrids containing Bacillus thuringiensis (Bt) enzymes (Bt-maize hybrids), were planted in a field study. Mature, midgestation, beef cows (Bos tarus) strip-grazed post-harvest residues as paddocks over 126 days. Body condition-scores and weights were monitored. Forage yield, weathering losses and forage composition were monitored on grazed and ungrazed areas. Forage selection and intake were estimated. Grain yields, dropped grain, initial crop residue concentrations of dry matter (DM), organic matter (OM) and in vitro digestible organic matter (IVDOM) yields were similar among hybrids. Hybrids varied in infestation of maize borers, …
Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
IGC Proceedings (1977-2023)
Winter forage availability in Sudan is constrained by lack of a suitable annual winter forage crop. The main forage crop grown is Abu70 (Sorghum bicolor) which is a summer crop that yields 7.6-8.4 t/ha in summer but much less in winter. There is, therefore, need for a winter high yielding forage crop that exceeds Abu70 in productivity and quality. This study was aimed to evaluate four forage maize cultivars as potential winter crops in central Sudan in terms of productivity and quality. An experiment was conducted using four maize forage cultivars. The experiment lasted for two consecutive seasons …

Department of Agronomy and Horticulture: Faculty Publications
Despite the potential to increase soil organic matter, cycle soil nutrients, and suppress weeds, there is a concern that cover crops (CCs) soil water use negatively impacts subsequent crops in water-limited environments. Cover crop management practices such as planting and termination timing may mitigate the detrimental impacts of CCs in semi-arid cropping systems. To determine the effects of CCs under water-limited environments, we evaluated the total CC biomass produced in the fall and spring, soil water content during the subsequent maize growing season, weed density and biomass, crop residue, and soil nutrients at the maize V6 development stage, and maize …
Contributions Of Individual Cover Crop Species To Rainfed Maize Production In Semi-Arid Cropping Systems, Alexandre T. Rosa, Cody Creech, Roger W. Elmore, Daran Rudnick, John L. Lindquist, Liberty Butts, Italo K. Pinho De Faria, Rodrigo Werle
Contributions Of Individual Cover Crop Species To Rainfed Maize Production In Semi-Arid Cropping Systems, Alexandre T. Rosa, Cody Creech, Roger W. Elmore, Daran Rudnick, John L. Lindquist, Liberty Butts, Italo K. Pinho De Faria, Rodrigo Werle
Department of Agronomy and Horticulture: Faculty Publications
Cover crop (CC) species selection can contribute to reducing soil penetration resistance (brassica species), improved soil nitrogen (N) cycling (legume species), and suppression of weeds (grass species). However, one of the main concerns about including CCs in water-limited environments is soil water use and the consequences to subsequent crops. To determine the effects of individual CC species under water-limited environments, we evaluated fall and spring CC biomass produced, and soil water and N content, penetration resistance, weed density and biomass during the maize growing season, and maize grain yield. The experiment was conducted under a winter wheat-maize-fallow rotation at two …

Tandem Duplicate Expression Patterns Are Conserved Between Maize Haplotypes Of The Α-Zein Gene Family, Preston Hurst, James C. Schnable, David R. Holding
Tandem Duplicate Expression Patterns Are Conserved Between Maize Haplotypes Of The Α-Zein Gene Family, Preston Hurst, James C. Schnable, David R. Holding
Department of Agronomy and Horticulture: Faculty Publications
Tandem duplication gives rise to copy number variation and subsequent functional novelty among genes as well as diversity between individuals in a species. Functional novelty can result from either divergence in coding sequence or divergence in patterns of gene transcriptional regulation. Here, we investigate conservation and divergence of both gene sequence and gene regulation between the copies of the α-zein gene family in maize inbreds B73 and W22. We used RNA-seq data generated from developing, self-pollinated kernels at three developmental stages timed to coincide with early and peak zein expression. The reference genome annotations for B73 and W22 were modified …

The Philippine Agricultural Scientist
One of the new strategies to increase the effectiveness of chemical fertilizers, prevent the waste of chemical fertilizers, and increase the yield of agricultural products, is the use of natural compound such as zeolite. This study was conducted to investigate the effects of zeolite (0, 5, 10, and 15 t ha-1) on agronomic and biochemical responses as well as yield components of maize (cv. Simon) under normal (90% field capacity), moderate (75% FC), and severe (60% FC) drought stress conditions during 2017-2019. The results showed that moderate and severe drought stress significantly decreased plant height (10.9% and 19.7%, …

Department of Agronomy and Horticulture: Faculty Publications
Root-associated microbes are key players in plant health, disease resistance, and nitrogen (N) use efficiency. It remains largely unclear how the interplay of biological and environmental factors affects rhizobiome dynamics in agricultural systems. In this study, we quantified the composition of rhizosphere and bulk soil microbial communities associated with maize (Zea mays L.) and soybean (Glycine max L.) in a long-term crop rotation study under conventional fertilization and low-N regimes. Over two growing seasons, we evaluated the effects of environmental conditions and several treatment factors on the abundance of rhizosphere- and soil-colonizing microbial taxa. Time of sampling, host plant species, …

Resistance To Aflatoxin Accumulation In Maize Mediated By Host-Induced Gene Silencing Of Aspergillus Flavus Alkaline Protease And O-Methyltransferase-A Genes, Olanike Omotola Omolehin
LSU Doctoral Dissertations
Aspergillus flavus is a soil-borne fungal pathogen that infects maize and produces aflatoxins. In the current study, portions of the alkaline protease (alk) and the O-methyl transferase (omtA) genes, which are key in A. flavus virulence and aflatoxin biosynthesis, respectively, were targeted for suppression through an RNAi (RNA interference) approach known as Host-Induced Gene Silencing (HIGS). Separate RNAi vectors were designed to carry regions of the alk and omtA gene fragments (Alk-RNAi and OmtA-RNAi) and introduced into B104 maize zygotic embryos. Eight and six transformation events were positive for the alk and omtA transgene, respectively. …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein
Department of Entomology: Faculty Publications
Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

IGC Proceedings (1977-2023)
Maize is the third most important cereal crop of the world and so also in India (Nadagoud et al., 2012). The diverse use of maize is rapidly increasing the demand of the crop and is replacing crops such as rice, sorghum, legumes and wheat in some areas (CIMMYT, 2013). Maize is largely treated as a single-purpose crop grown for grain, ignoring its potential for stover. Utilization of maize as dual purpose can meet the demand of both the poultry industry for grain and good quality stover for cattle feed. Maize stover the part of the crop left over after grain …

IGC Proceedings (1977-2023)
In the South Island of New Zealand (NZ), dairy cow numbers have increased from 1.4 to 2.1 million since 2005 (Statistics, New Zealand, 2014). This has led to a strong demand for winter feed crops in place of pasture, and also for supplementing pasture during lactation. Yields of 19–35 t DM/ha are reported for fodder beet (Beta vulgaris L.) in NZ (Chakwizira et al., 2014) compared with 14–25 t DM/ha for forage kale (Brassica oleracea L.) (Chakwizira et al., 2009) and 18–25 t DM/ha for maize (Zea mays L.). Fodder beet has only recently been …

IGC Proceedings (1977-2023)
For continuous genetic improvement of cows, nutrition and management conditions should be improved to allow cow to produce its inherited potential production. However, many farmers not pay desired attention on forage quality and one of the main reasons for the low productivity of dairy cattle is under nutrition. Therefore, production of high quality fodder varieties is vital for strengthening the dairy sector in Sri Lanka. Hybrid Napier var. CO-3 is widely used for cattle feeding in Sri Lanka. It is important to find out other forage varieties with maximum nutritive values and minimum anti-nutritive factors which can be used as …

IGC Proceedings (1977-2023)
The low fertility status of most tropical soils has hindered maize production as maize has a strong exhausting effect on the soil. It has been generally observed that maize fails to produce good grain in plots without adequate nutrients (Adediran and Banjoko 2003). Legumes generally are able to fix nitrogen to the soil which the companion crop could benefit from, but usually the nitrogen fixed occurs in insufficient quantities for marginally nitrogen sensitive crops such as maize and hence the required use of fertilizers. Inorganic fertilizers exert strong influences on plant growth, development and yield (Stefano et al. 2004). …

Feed constraint is the most important impediment to improved livestock production in the Sub-Saharan African (SSA) countries (Agyemang 2003), as a result of seasonal shortages in the quantity and quality of forage from natural pastures that supply most of the feed for animals due to the prolonged annual dry season. Appropriate technologies to improve the performance of the local animal breeds and feed resources under the traditional system are generally lacking. Maize forms a major part of the cereal crops consumed by man and the residues serve as a source of fodder for livestock (Asawalam and Adesiyan 2001). Demand for …

Benchmarking crop yields against nitrogen (N) input levels can help provide opportunities to improve N ferti-lizer efficiency and reduce N losses on maize in the US Corn Belt by identifying fields most likely to benefit from improved N management practices. Here, we evaluated a large producer database that includes field-level data on yield and applied N inputs from 9280 irrigated and rainfed fields over a 7-year period (2009–2015) in Nebraska (USA). A spatial framework, based on technology extrapolation domains, was used to cluster each field into spatial units with similar climate and soil type that represent 1.3 million ha of …

Heterosis, or hybrid vigour, is a predominant phenomenon in plant genetics, serving as the basis of crop hybrid breeding, but the causative loci and genes underlying heterosis remain unclear in many crops. Here, we present a large-scale genetic analysis using 5360 offsprings from three elite maize hybrids, which identifies 628 loci underlying 19 yield-related traits with relatively high mapping resolutions. Heterotic pattern investigations of the 628 loci show that numerous loci, mostly with complete–incomplete dominance (the major one) or overdominance effects (the secondary one) for heterozygous genotypes and nearly equal proportion of advantageous alleles from both parental lines, are the …

Benchmarking On-Farm Maize Nitrogen Balance In The Western U. S. Corn Belt, Fatima Amor Tenorio
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
A nitrogen (N) balance, calculated as the difference between N inputs and grain-N removal, provides an estimate of the potential N losses. We used N balance with other N-related metrics (partial factor productivity for N inputs, and yield-scaled N balance), to benchmark maize yields in relation with N input use in the US Corn Belt. We first used experimental data on grain-N concentration (GNC) to assess variation in this parameter due to biophysical and management factors. Subsequently, we used N balance and N-related metrics to benchmark yields in relation with N inputs in irrigated and rainfed fields in Nebraska using …

Maize is one of major crop species over the world. With lots of genetic resources and genomic tools, maize also serves as a model species to understand genetic diversity, facilitate the development of trait extraction algorithms and map candidate functional genes. Since the first version of widely used B73 reference genome was released, independent research groups in the maize community propagated seeds themselves for further research purposes. However, unexpected or occasional contamination may happen during this process. The first study in this thesis used public RNA-seq data of B73 from 27 research groups across three countries for calling single nucleotide …
