Climate Change And Seed Security Among Smallholder Farmers In Northern Ghana, Michael Biwalib Madin

Electronic Theses and Dissertations

Smallholder agriculture is highly susceptible to climate variability and change. According to recent projections by the Intergovernmental Panel on Climate Change, this sensitivity would likely increase in the coming decades, with more erratic rainfall, prolonged dry periods, shorter growing seasons, and seed germination failures. In the African context, the mechanisms through which these ecological stressors would affect seed security are poorly understood. Drawing upon a case study of semi-arid Ghana, this study examines climate change impacts on seed security among smallholder farmers. It adopts a mixed-methods approach with intensive fieldwork in two farming communities. Conceptually, the study uses a political …

Turkish Journal of Agriculture and Forestry

This study investigated the interactions between topsoil properties and ecophysiological responses of Avicennia marina along the tidal gradient in an arid region in Qatar. In February 2017, three plots were established, each at a distance of 0 m (D0), 50 m (D50), and 100 m (D100) from the inland boundary of a mangrove forest. Soil samples were collected at 0-10-cm depth in each plot to determine the chemical properties, and the density of seedlings, saplings, and trees was measured. Moreover, above- (AGB) and below-ground biomass (BGB) were calculated using an allometric equation for A. marina with the measured diameter at …

Fireanalyst: An Effective System For Detecting Fire Geolocation And Fire Behavior In Forestsusing Mathematical Modeling, Yücel Güllüce, Rahmi̇ Nurhan Çeli̇k

Turkish Journal of Agriculture and Forestry

This study proposes an effective new fire detection method and monitoring software for an early-warning fire detection system aimed at valuable forested areas, such as botanical parks or high conservation value forests, particularly those with boundaries. These critical forested areas need to be appropriately managed because they contain large concentrations of biological diversity, including threatened or endangered species, which are very susceptible to fire outbreaks; thus, early detection of fire and rapid response have a very important place in the fight against fire in those areas. In this proposed system, special detectors with state-of-the-art multispectral infrared technology and mathematical modeling …

Turkish Journal of Agriculture and Forestry

In the current study, significant variations were identified for seven fruit traits of the walnut accessions. The highest correlations were detected between nut height and nut width, and between nut weight and kernel weight. Most traits had a continuous normal binominal distribution. A total of 16,774 single-nucleotide polymorphism (SNP) markers based on diversity arrays technology were generated and after filtering the missing data, the remaining 13,611 SNP data were used for genotyping. STRUCTURE (v.2.2) analysis revealed two possible scenarios (K = 3 and K = 5) according to the results of ΔK computation. While K = 3 indicated that walnut …

Planting Date, Cultivar, Seed Treatment, And Seeding Rate Effects On Soybean Growth And Yield, Thandiwe Nleya, Matthew Schutte, David Clay, Graig Reicks, Nathan Mueller

West Central Research and Extension Center, North Platte

Soybean [Glycine max (L.) Merr.] yield is a function of many factors including genetic attributes of the cultivar, environmental conditions, and management practices. Temporally variable weather patterns in North America, especially in the northern Great Plains, have resulted in the re-examination of how spring production practices interact with the environmental conditions to influence yield. This study evaluated the impact of four plantings dates, four seeding rates, and two soybean maturity groups (MGs) using treated and untreated (control) seed on soybean growth, seed yield, and composition. The study was conducted at Volga, SD, in 2014, 2015, and 2016. The planting …

Herbicide Drift Exposure Leads To Reduced Herbicide Sensitivity In Amaranthus Spp., Bruno Viera, Joe Luck, Keenan Amundsen, Rodrigo Werle, Todd A. Gaines, Greg R. Kruger

West Central Research and Extension Center, North Platte

While the introduction of herbicide tolerant crops provided growers new options to manage weeds, the widespread adoption of these herbicides increased the risk for herbicide spray drift to surrounding vegetation. The impact of herbicide drift in sensitive crops is extensively investigated, whereas scarce information is available on the consequences of herbicide drift in non-target plants. Weeds are often abundant in field margins and ditches surrounding agricultural landscapes. Repeated herbicide drift exposure to weeds could be detrimental to long-term management as numerous weeds evolved herbicide resistance following recurrent-selection with low herbicide rates. The objective of this study was to evaluate if …

West Central Research and Extension Center, North Platte

Optimizing beef production system efficiency requires an understanding of genetic potential suitable for a given production environment. Therefore, the objective of this retrospective analysis was to determine the influence of cow body weight (BW) adjusted to a common body condition score (BCS) of 5 at weaning-influenced cow-calf performance and postweaning steer and heifer progeny performance. Data were collected at the Gudmundsen Sandhills Laboratory, Whitman, NE, on crossbred, mature cows (n = 1,607) from 2005 to 2017. Cow BCS at calving, prebreeding, and weaning were positively associated (P < 0.01) with greater cow BW. Increasing cow BW was positively associated (P < 0.01) with the percentage of cows that conceived during a 45-d breeding season. For every additional 100-kg increase in cow BW, calf BW increased (P < 0.01) at birth by 2.70 kg and adjusted 205-d weaning BW by 14.76 kg. Calf preweaning average daily gain (ADG) increased (P < 0.01) 0.06 kg/d for every additional 100-kg increase in cow BW. Heifer progeny BW increased (P < 0.01) postweaning with every additional 100-kg increase in dam BW. Dam BW did not influence (P ≥ 0.11) heifer puberty status prior to breeding, overall pregnancy rates, or the percentage of heifers calving in the first 21 d of the calving season. Steer initial feedlot BW increased by 7.20 kg, reimplant BW increased by 10.47 kg, and final BW increased by 10.29 kg (P ≤ 0.01) for every additional 100-kg increase in dam BW. However, steer feedlot ADG was not influenced (P > 0.67) by dam BW. Hot carcass weights of steers were increased (P = …
