Tétel Szabadon hozzáférhető Assessment of electrical conductivity and germinability of groundnut genotype seeds(2025-06-08) Akuo, Ruth; Okiria, Latif Aisu; Ssemugenze, Brian; Gumisiriya, Costa; Kabaale, Fred Peter; Ocwa, AkasairiSeed quality affects crop establishment and productivity. In addition, the use of good-quality seed is an essential prerequisite for sustainable crop production including groundnuts. Assessing germinability and electrical conductivity provides early evidence of the production potential of a given crop variety or genotype. Therefore, this study assessed the germinability and electrical conductivity of seeds of three groundnut genotypes. A laboratory experiment arranged in a Completely Randomized Design (CRD), replicated three times, was conducted at the Faculty of Agriculture, Kyambogo University, in 2020. Seeds of Igola, Serenut 1, and Serenut 2 groundnut varieties were tested, and data was collected on germination percentage and electrical conductivity. Analysis of variance (ANOVA) was performed using GenStat and means were separated using the least significant difference test at a 5% probability level. Germination percentage and electrical conductivity significantly (p<0.05) differed among the groundnut varieties, with Igola recording the highest germination percentage, followed by Serenut 1, and the lowest was in Serenut 2. The highest electrical conductivity was recorded in Serenut 1 and the lowest in Igola. Since Igola had one of the lowest electrical conductivity and the highest germination percentage, it was concluded that Igola genotype retained higher quality attributes.Tétel Szabadon hozzáférhető The effect of soil tillage and nutrient supply on maize yield based on multi-year experimental results(2025-07-22) Ragán, Péter; Rátonyi, Tamás; Fejér, Péter; Harsányi, Endre; Balláné Kovács, Andrea; Gumisiriya, Costa; Nagy, János; Sojnóczki, István; Tamás, AndrásTo optimize maize (Zea mays) yield, soil tillage and nutrient supply play a key role. The application of appropriate soil tillage techniques and the precise application of nutrients can contribute to increasing yield, maintaining plant health, and developing sustainable agricultural practices. The aim of the study was to analyse the long-term yield performance of maize hybrids under different nutrient supply levels and basic tillage methods. According to the repeated measurement model, soil tillage, fertilization, and crop year had a significant (p<0.001) effect on maize yield. The integrated approach allows for the optimization of yield and the development of sustainable agricultural practices. Reduced soil tillage methods reduce soil erosion and improve soil biological activity.Tétel Szabadon hozzáférhető Enhancing Maize Production Through Timely Nutrient Supply: The Role of Foliar Fertiliser Application(2025) Ssemugenze, Brian; Ocwa, Akasairi; Kuunya, Ronald; Gumisiriya, Costa; Bojtor, Csaba; Nagy, János; Széles, Adrienn; Illés, ÁrpádTétel Szabadon hozzáférhető Improving the agronomic performance of maize: differential responses to precision irrigation(2025) Ocwa, Akasairi; Ssemugenze, Brian; Kuunya, Ronald; Gumisiriya, Costa; Balaout, Ibtissem; Bojtor, Csaba; Illés, Árpád; Harsányi, EndreTétel Szabadon hozzáférhető Maize nutrient dynamics: growth, yield and sustainable practices: A narrative review(2025) Ahmed, Osman Magdoline Mustafa; Kuunya, Ronald; Abakeer, Rania Alrasheed; Hassan, Mohammed Mahgoub; Wasikoyo, Erastus Masika; Gumisiriya, Costa; Mudawi, Hanan Ibrahim; Elsalahi, Randa H.; Rátonyi, TamásTétel Szabadon hozzáférhető Maize nutrient dynamics: growth, yield and sustainable practices: A narrative review(2025-12-02) Osman, Magdoline Mustafa Ahmed; Kuunya, Ronald; Alrasheed, Raina; Hassan, Mohammed M.; Wasikoyo, Erastus; Gumisiriya, Costa; Mudawi, Hanan ibrahim; Elsalahi, Randa; Rátonyi, TamásNutrient acquisition is the fundamental regulator of maize (Zea mays) growth, development, and yield. The present narrative review intends to integrate existing information on dynamics of nutrient uptake in maize under scrutiny for understanding how the processes affect growth and yield. We focus on the effective absorption and utilization of macronutrients (N, P and K) and micronutrients that promote plant health, grain development, and stress tolerance. Key determinants of nutrient availability (soil type, pH, organic matter, environment) and physiological or yield impacts of deficiency are studied. Strategies to optimize uptake efficiency precision application of fertilizer, organic fertilizers, and sustainable soil management are discussed. Optimizing these dynamics is central to maize productivity, enhancement and sustainable crop production. This review provides valuable insights into optimizing maize nutrition for improved food security and sustainable crop production.Tétel Szabadon hozzáférhető Physiological Growth Improvement of Maize (Zea mays L.) through Foliar Fertilisation under Irrigated Conditions(2025) Ssemugenze, Brian; Ocwa, Akasairi; Kuunya, Ronald; Gumisiriya, Costa; Bojtor, Csaba; Illés, Árpád; Nagy, JánosTétel Szabadon hozzáférhető Seasonal Changes in the Soil Microbiome on Chernozem Soil in Response to Tillage, Fertilization, and Cropping System(2025) Balláné Kovács, Andrea; Juhász, Evelin Kármen; Béni, Áron; Gumisiriya, Costa; Tállai, Magdolna; Szabó, Anita; Kincses, Sándorné; Novák, Tibor; Tamás, András; Kremper, RitaTétel Szabadon hozzáférhető Soil moisture sensors for sustainable water management in field crop production: A review of advances and application challenges(2025-12-02) Kuunya, Ronald; Osman, Magdoline Mustafa Ahmed; Ssemugenze, Brian; Gumisiriya, Costa; Ragán, PéterEfficient 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.Tétel Szabadon hozzáférhető Soil moisture sensors for sustainable water management in field crop production: A review of advances and application challenges(2025) Kuunya, Ronald; Ahmed, Osman Magdoline Mustafa; Ssemugenze, Brian; Gumisiriya, Costa; Ragán, Péter
