Black Soldier Fly-Composted Organic Fertilizer Enhances Growth, Yield, And Nutrient Quality Of Three Key Vegetable Crops In Sub-Saharan Africa, Abel O. Anyega, Nicholas K. Korir, Dennis Beesigamukama, Ghemoh J. Changeh, Kiatoko Nkoba, Sevgan Subramanian, Joop J.A. Van Loon, Marcel Dicke, Chrysantus M. Tanga

All Peer-Reviewed Publications

Worldwide, French beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), and kales (Brassica oleracea L. var. acephala) are considered economically important food crops. There is a rapid decline in their yield due to severe soil degradation. Thus, high commercial fertilizer inputs are crucial, though they remain expensive and inaccessible to resource poor farmers. We investigated the comparative performance of composted black soldier fly frass fertilizer (BSFFF), conventionally composted brewer's spent grain (BSG), commercial organic fertilizer (Evergrow), and mineral [nitrogen, phosphorus, and potassium (NPK)] fertilizer on growth, yield, N use efficiency, and nutritional quality (crude protein, crude fiber, crude fats, ash, …

Rhizosphere Microbiomes In A Historical Maize-Soybean Rotation System Respond To Host Species And Nitrogen Fertilization At The Genus And Subgenus Levels, Michael A. Meier, Martha G. Lopez-Guerrero, Ming Guo, Marty Schmer, Josh Herr, James Schnable, James R. Alfano, Jinliang Yang

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, …

Using Thermal Imaging To Measure Water Stress In Creeping Bentgrass Putting Greens, Joseph G. Foral Jr.

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Thermal imaging is a developing tool that can help turf managers reduce water consumption and improve irrigation scheduling, but in-depth studies are needed to maximize this potential. This study evaluated the ability of thermal imaging to identify water stress in a creeping bentgrass (Agrostis stolonifera ‘007’) putting green. Water use and canopy temperature (T_c) were measured for plots subjected to three levels of measured water replacement (full, half, and none) to evaluate changes over a range of soil water potentials (SWP). Water use was consistent across the irrigation treatments up to several days before observed wilt …

Morphophysiological And Molecular Characterization Of Millet (Panicum Miliaceum L.) Varieties For Crop Improvement In Western Europe, Massimo Vischi, Nicola Zorzin, Maria Bernhart, Johanna Winkler, Dipak Santra, Carla Pappalardo, Stefano Marchetti

Department of Agronomy and Horticulture: Faculty Publications

Background

Global warming and issues in favour of a more sustainable agriculture suggest a reconsideration of minor cereals in European agrosystems. Compared to other summer crops, proso millet has a remarkable drought resistance and could be used to improve crop rotation and biodiversity. Proso millet is also increasingly sought by industry to produce novel foods such as those designed for celiac patients. In this study, a thorough characterization of 11, commercially available, proso millet (Panicum milliaceum L.) varieties was carried out as a preliminary step for crop reintroduction and breeding in Western Europe.

Methods

The cultivars under evaluation were …

Effects Of Compost On Soil Health And Greenhouse Gas Emissions: A Case Study In A Mediterranean Vineyard, Tsz Fai Wong

Master's Theses

Compost is commonly used as an organic amendment in cropping systems such as vineyards, and has been shown to be beneficial to carbon (C) sequestration and soil health. As perennial crops, grapevines have a larger potential for C sequestration than most crops. Yet, there is a lack of understanding regarding the relationship between compost application rate, the magnitude of C sequestration, and its environmental tradeoff in the form of greenhouse gas (GHG) emissions. In the study, we investigated the effects of compost application rate on soil C sequestration, GHG emissions, crop growth, and overall soil health after two annual compost …

Could Fall Armyworm, Spodoptera Frugiperda (J. E. Smith) Invasion In Africa Contribute To The Displacement Of Cereal Stemborers In Maize And Sorghum Cropping Systems, Girma Hailu, Saliou Niassy, Timon Bässler, Nathan Ochatum, Christoph Studer, Daisy Salifu, Mawufe K. Agbodzavu, Zeyaur R. Khan, Charles Midega, Sevgan Subramanian

All Peer-Reviewed Publications

The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith), which has recently invaded the African continent, has become a new threat to cereal production. Being an invasive pest with certain competitive advantages, the impact of FAW on other lepidopteran pests is unclear. This study assessed the infestation of FAW and cereal stemborers on maize and sorghum under mono-cropped systems that are adjacently placed in five districts in Uganda. Data on maize and sorghum infestation cereal stemborers and FAW was collected at 6, 9 and 16 weeks after planting (WAP), to determine intensity and severity. Cereal stemborer infestations on maize at 6, …

Farm‐Scale Assessment Of Maize–Pigeonpea Productivity In Northern Tanzania, E. Mugi-Ngenga, S. Zingore, L. Bastiaans, N. P.R. Anten, K. E. Giller

All Peer-Reviewed Publications

Little is known about productivity of smallholder maize–pigeonpea intercropping systems in sub-Saharan Africa. We conducted a survey of 277 farm households in Northern Tanzania to assess socio-economic factors, field management characteristics, and their association with productivity of maize–pigeonpea intercrops. On each farm, crop assessments were focused on a field that the farmer identified as most important for food supply. Variables associated with yields were evaluated using linear regression and regression classification. Biomass production ranged between 1.0 and 16.6 for maize, and between 0.2 and 11.9 t ha−1 for pigeonpea (at maize harvest). The corresponding grain yields ranged between 0.1 and …

Improved Taste And Texture In Novel Popcorn Varieties Compared To Conventional Lines, Leandra Parsons, Oscar Rodriguez, David R. Holding

Department of Agronomy and Horticulture: Faculty Publications

Abstract Quality Protein Popcorn (QPP) varieties were bred out of a unique germplasm pool derived from Quality Protein dent Maize and conventional popcorn lines. To identify and compare distinctive characteristics within this population, a new sensory method was employed that coupled hedonic numeric rankings of common sensory traits appearance, aroma, texture, and taste with an “overall likability” score while requiring the selection of specific descriptors for taste and texture. Participants tasted six popcorn cultivars, rated each sample based on sensory factors, and offered specific descriptors for taste and texture. This sensory method identified two QPP hybrids with higher overall likability …
