Cím:Climate change mitigation and livelihood components under smallholder cofee farming : a bibliographic and systematic review / Noel Kishaija, Akasairi Ocwa, Ronald Kuunya, Brian Ssemugenze, Bálint Heil
Dátum:2025
ISSN:2048-7010
Megjegyzések:Cofee ranks high in terms of growth, trade, and consumption across the world. Although there has been an increasing trend in its consumption as a beverage across the globe, its on-farm production and productivity are threatened by climate change in the dominant cofee-growing regions. Smallholder farmers produce about 80% of the world`s cofee and are constrained in adopting climate-smart improved technologies. Climate change and livelihoods are interconnected, and understanding and strengthening their linkages is crucial in generating sustainable cofee supplies. This paper analyzed climate change and mitigation components in the context of livelihoods under smallholder cofee farming systems. An online search of globally published journal articles was done in the Web of Science and Google Scholar databases. Bibliographic and metadata analysis was done using VOSviewer software, while the publication trend of the included articles was analyzed using Mann-Kendall. Overall, this review reveals that livelihood assets owned by the cofee farmer have a strong bearing on the adaptation and mitigation of climate change, while Fairtrade certifcation has mixed efects on farmers` income and well-being. Agroforestry is a major climate change adaptation strategy under cofee farming and is linked to the livelihood status of the farmer, gender, and certifcation. This review echoes the strong linkage between agroforestry, livelihood components, and Fairtrade certifcation under smallholder farmers based on the empirical researched information available

Cím:Assessment of Soil Electrical Conductivity and Yield Responses of Maize Hybrids under different Plant Densities / Ronald Kuunya , Magdoline Mustafa Ahmed, Brian Ssemugenze, Costa Gumisiriya, András Tamás, Péter Ragán
Dátum:2025
Megjegyzések:Different maize hybrids vary in nutrient uptake efficiency. Plant density influences nutrient absorption, which affects yield at different growth stages such as germination, tasselling, and kernel development. Few studies have examined the relationship between soil electrical conductivity (EC) and maize yield under varying plant densities. This research aimed to identify optimal hybrid?density combinations for improved productivity and resource use efficiency. The experiment was conducted in 2024 at the Látókép Experimental Station (Debrecen, Hungary) under strip tillage on non-irrigated chernozem soil. Three maize hybrids (Merida, Fidencio, and P9985) were cultivated at two plant densities (60,000 and 80,000 plants ha-1) with a fertiliser rate of 80 kg Nitrogen ha-1 plus basal Phosphorus and Potassium. Soil EC was measured monthly with a portable sensor from planting to cob formation, and grain yield was determined at harvest. Data were aggregated by hybrid?plant density and statistically analysed using SPSS Software (IBM v20), with significance evaluation at p ? 0.05. Results revealed no significant correlations among hybrid, EC, plant density, and yield. This shows that neither EC nor plant density reliably predicts yield, suggesting other factors, such as soil moisture and fertility, that may exert stronger influence. Future studies should examine interactions between EC and other factors affecting maize productivity. Moreover, long-term studies across multiple seasons and diverse soil types could clarify EC patterns under varying environmental conditions, tillage systems, and irrigation regimes.

Cím:Soil moisture sensors for sustainable water management in field crop production : A review of advances and application challenges / Ronald Kuunya, Magdoline Mustafa Ahmed Osman, Brian Ssemugenze, Costa Gumisiriya, Péter Ragán
Dátum:2025
Megjegyzések:Efficient water management is essential for sustainable production of field crops amid climate change, population growth, and water scarcity. Traditional irrigation practices often lead to water use inefficiency, which harms soil health and reduces yields. To address this, reviewing previous studies on soil moisture sensors provides important context and guidance. Literature from Scopus, Google Scholar, and WoS (2019?2025) on soil moisture sensors for sustainable water management in field crops was screened. Out of 244 retrieved publications, 79 met the inclusion criteria with a focus on sensor technologies, applications, advances, and challenges, analysed thematically for research gaps and insights. Based on the findings, soil moisture sensors boost water management, improve yields of field crops, and support sustainable agriculture. However, hindrances related to high costs, lack of awareness, technical complexity, calibration needs, energy challenges, data interpretation difficulties, and compatibility problems hinder effective soil moisture sensor results. Integrating soil moisture sensors with decision-support tools optimises water use and protects soil health to promote long-term productivity under climate variability. Future research should strategise on the development of low-cost, reliable soil moisture sensors with technology subsidies, training, policy support, durability, integration, and simple data to empower farmers to adopt precision water management.

Cím:Impact of Winter Ploughing Tillage on Moisture Content and Grain Hardness in Wheat : A Statistical Analysis of Harvested Samples / Ronald Kuunya, Magdoline Mustafa Ahmed Osman, Brian Ssemugenze, Akasairi Ocwa, András Tamás, Péter Ragán
Dátum:2025
ISSN:2223-7747
Megjegyzések:Winter ploughing is a soil tillage practice performed between harvest of the previous crop and planting of the next one within the winter months. This study investigates the impact of the tillage practice on the quality of wheat grain, focusing on two key parameters: moisture content and grain hardness. A total of 72 wheat grain samples were collected from a field at Látókép Experimental Station (Debrecen, Hungary), where winter ploughing was applied before sowing and harvesting. The two parameters were measured using a grain analyser, and the results were subjected to Past4.11 Statistical Software for analysis. The mean moisture content of the wheat grains was 11.907%, with a standard error of 0.0787 and a 95% confidence interval ranging from 11.75% to 12.064%. Grain hardness averaged 106.49 psi, with a standard error of 1.8856 and a 95% confidence interval of 102.73 psi to 110.25 psi. The results revealed moderate variability in both moisture content and grain hardness, with skewness values of 0,264254 and -0,4254446, indicating slight asymmetry in both parameter distributions. Statistical analyses, including t-tests and confidence intervals of 1,9768 at p=0.05 confirmed the reliability of the observed results. These findings suggest that winter ploughing tillage contributes to stable moisture retention but shows variable effects on grain hardness, possibly due to factors such as soil conditions and environmental variability. Further research is recommended to explore the long-term effects of winter ploughing on wheat quality and yield, as well as its impact under different weather conditions and wheat varieties.

Cím:Remote sensing technology as a better technique for assessing land degradation / Ronald Kuunya, Éva Horváth, Akasairi Ocwa, Brian Ssemugenze, Adrienn Széles, Péter Ragán
Dátum:2024
Megjegyzések:As the world population rises, the demand for basic life needs increases: this is mainly so with changes in the types and amount of food that will be required per person in order to counteract the resultant escalated impact. Among the large scale disasters referred to is land degradation which affects the processes by which defined populations must be fed, particularly through the crop sector. According to sources, land degradation affects the value of both biophysical and biochemical environment through a blend of human-induced actions upon the land, most of which are considered deleterious or undesirable. To be specific, land degradation worsens the infertility of soil in terms of reduced soil health, productivity, and biodiversity. For the purpose of assessing the impact, attempts are made in such a way that provides maximum productivity with minimum environmental challenges, and less wasted effort or expense. These include; systematising erosion basing on the forms of erosion, and applying quality scales to combat the severity of soil erosion, among others. This work reviews the suitability of desirable applications for determining the possible consequences and potential management measures against land degradation. Remote sensing was applied as a non-intrusive measure whose electromagnetic energy was recorded by passive sensors with no or less disturbance of the land surface; therefore, researchers would be able to monitor the natural soil condition without altering it. Primarily, applications were applied with a target of detecting and identifying the features that would adversely affect the biological or economic productivity of land. The success of the applications was based on the resolution and extent of spatial, spectral, radiometric, and temporal data. Consequently, it is crucial to devise radiometers and photometers with high efficiency that can aid the assessment of land degradation. One important aspect is that remote sensing technology allows collection of data even in land areas that are inaccessible. Nonetheless, this is limited by the lack of user-functional skills and the high cost attached. From this viewpoint, a study is needed to explore more precision facets that would enhance remote sensing as a technology for determining the land degradation challenge.

Cím:Management of biodegradable farm waste using black soldier fly larvae / Ronald Kuunya, Akasairi Ocwa, Brian Ssemugenze, Adrienn Széles, Péter Ragán
Dátum:2024
ISSN:1583-4301 2065-3484(angol kiad.)
Megjegyzések:Farm waste accumulation is a direct outcome of the increasing agricultural operations by humans. As such, there is need to develop and embrace proper strategy to deal with this challenge. The use of Black Soldier Fly Larvae is one of the methods employed in addition to landfilling, incineration, and source reduction, among others. This paper reviews the most recent contribution of the Black Soldier Fly Larvae in dealing with farm waste in a sustainable way. BSFL was used to degrade organic waste from different sources linked to manure, barnyards, feedlot runoff, and slaughterhouses. Black Soldier Fly Larvae was efficient in transforming low-value organic resources into a more quality source of protein feed for farm animals such as poultry and fish. However, the impediments to the use of Black Soldier Fly Larvae technology included negative public perception, high infrastructure requirements, lack of adequate sensitisation, tough regulatory hurdles, and waste segregation. Therefore, sustainable waste management requires careful attention to human health and with economic and legislative considerations.

Cím:Maize leaf greenness and yield differential response to the biostimulating effect of Bacillus simplex under irrigation / Akasairi Ocwa, Brian Ssemugenze, Csaba Bojtor, Árpád Illés, Ronald Kuunya, Latif Aisu Okiria, Tamás Rátonyi, Endre Harsányi
Dátum:2025
ISSN:1332-9049
Megjegyzések:The use of bioinoculants continues to gain research attention due to the need to ensure sustainable soil and crop productivity under climate change. Soil and Plant Analysis Development (SPAD) and Normalized Difference Vegetation Index (NDVI) are useful indicators of leaf greenness that have a positive nexus with yield. These parameters are proper indicators of treatment effects. Therefore, this study examined the biostimulating effect of Bacillus simplex seed inoculation on leaf greenness and yield of maize under irrigated conditions. A field experiment with treatments consisting of maize seeds inoculated with Bacillus simplex and a control under irrigation was conducted. The SPAD and NDVI data were collected at the 12-leaf stage (V12), tasselling stage (VT) and Kernel blister stage (R2), while yield component and yield data were collected at harvest time. Analysed data revealed that Bacillus simplex seed inoculation significantly improved NDVI by 16.42% only at the R2 growth stage. Yield and yield components were significantly optimised by Bacillus simplex seed inoculation. Cob length, cob weight, weight of seeds per cob, number of seeds per cob and weight of 1000 seeds improved by 18.45%, 24.99%, 24.62%, 18.62% and 6.34%, respectively. The overall grain yield was optimised by 26.97% (3.12 t/ha). Therefore, Bacillus simplex can be used as a seed bioinoculant with irrigation to enhance sustainable maize production under climate change.

Cím:Interaction Effect of Foliar Fertilisation and Precision Drip Irrigation on Cob-related Yield Components in Maize Hybrids / Brian Ssemugenze, Akasairi Ocwa, Ronald Kuunya, Costa Gumisiriya, Noel Kishaija, Marveen Nafula, Hope Namara, Árpád Illés, Csaba Bojtor
Dátum:2025
Megjegyzések:Maize hybrid selection depends on several traits, including cob parameters. Hybrids respond differently to agronomic inputs, namely irrigation and fertilisation. Our study was conducted at Látókép Crop Production Experimental Site, University of Debrecen, Hungary, in 2023. The evaluation of the interaction effect of foliar fertilisation and precision drip irrigation on cob diameter, cob length, cob weight, and number of rows per cob in four maize hybrids (FAO390, FAO420, FAO430, FAO490) was performed under a randomised split-plot field experiment. Foliar fertiliser was applied at the 8th leaf stage when the plant's leaves had fully developed with enough leaf surface area to absorb nutrients such as nitrogen (10 g/L), zinc (8 g/L), K?O (8.5 g/L), P?O? (0.83 g/L), and sulphur (8.93 g/L). Surface drip irrigation lines fixed at each row delivered 3 litres of water per hour, managed by the HydraWise app. Data were analysed by ANOVA using Genstat (18th edition) software. Cob diameter and cob weight had significant differences (p < 0.01) between hybrids. FAO430 recorded the largest cob diameter (52.8 mm) and cob weight (31.5 g). Thus, the least performing hybrid, FAO420, exhibited a 10?15% difference, with a cob diameter of 47.9 mm and a cob weight of 23.7 g. Both cob length and number of rows per cob showed no significant differences (p > 0.05) among hybrids. FAO390 had a longer cob (19.7 cm) compared to FAO430 (18.4 cm). Irrigation had a significant effect on cob length (p < 0.001) and cob diameter (p < 0.05). Irrigated cobs had a 7.8% (cob length) and 2.1% (cob diameter) difference compared to non-irrigated cobs. Foliar fertilisation alone increased mean cob weight by 7% but no statistical significance across all traits. The interaction between foliar fertilisation and precision drip irrigation showed a positive effect on cob diameter (p < 0.001) and cob weight (p < 0.05) across all hybrids. Combined input application enhanced yield components compared to single-factor effects. Therefore, the interaction among hybrid type, precision drip irrigation, and foliar fertilisation has a profound effect on cob-related yield components.
