Mid- and better-parent heterosis for yield and its components within anthocyanin pigmentation classes in the F2 generation of a cowpea cross
(”Ion Ionescu de la Brad” Iași University of Life Sciences, 2026-09-03) Olunloyo, Akinrinade Akanni; Ogunjinmi, Samson Oguntola; Olla, Noah Olugbemiga
This study evaluated generation mean performance, used single marker analysis (SMA) to determine associations between pigmentation and yield traits, and estimated mid- and better-parent heterosis in F₂ phenotypic classes from a cross between TVu1 and Ibadan BPC performed in an insect-proof screenhouse at the Department of Agricultural Technology, Federal College of Forestry, Ibadan, Nigeria, using a randomised complete block design with three replications. The parents, F₁, and 300 F₂ plants were grown in 10-L pots and spaced with 60 cm between rows and 45 cm within rows. Two seeds were sown per pot and thinned to one plant. Self-pollination was ensured using pollination bags. The following traits were measured: days to flowering, pod length, number of seeds per pod, 100-seed weight, yield, and pigmentation scores. SMA was performed using one-way analysis of variance, and heterosis was estimated using ttests. Pigmentation classes were significantly associated with yield traits. Pigmented plants flowered earlier (47.56 days) and had longer pods (13.14 cm) and heavier seeds (11.05 g) than non-pigmented plants (53.10 days, 12.34 cm, and 10.71 g, respectively). Purple plants flowered earlier (44.10 days), produced more seeds per pod (11.41), and had a higher 100-seed weight (8.66 g) than white plants (46.29 days, 11.26 seeds, and 8.64 g, respectively). Immature pod pigmentation favoured earlier flowering (45.24 days), longer pods (13.33 cm), more seeds (12.00), and heavier seeds (10.15 g). Heterosis showed positive mid- and better-parent effects for 100-seed weight (35.05–45.68%). Pigmented classes showed superior performance for morphological marker selection in cowpea improvement.

Evaluation of empirical reference evapotranspiration estimation methods in the Ziway Area, Central Rift Valley, Ethiopia
(”Ion Ionescu de la Brad” Iași University of Life Sciences, 2026-09-16) Bikila, Gebeyehu Ashemi
Reference evapotranspiration (ETO) is a fundamental component of irrigation scheduling, estimation of crop water requirements, and sustainable water-resource management, particularly in semi-arid regions where water resources are limited. This study evaluated the performance of four empirical ETO estimation methods (Blaney–Criddle, Hargreaves, Radiation, and Modified Penman) against the FAO-56 Penman–Monteith method in the Ziway area of the Central Rift Valley, Ethiopia. Long-term meteorological data (1990–2023), including air temperature, relative humidity, sunshine duration, wind speed, and rainfall, were obtained from the Ziway Meteorological Station. The FAO-56 Penman–Monteith method implemented in CROPWAT 8.0 served as the benchmark, and model performance was evaluated using root mean square error (RMSE), mean absolute error (MAE), mean bias error (MBE), coefficient of determination (R2), Nash–Sutcliffe efficiency (NSE), Willmott’s index of agreement (d), mean absolute percentage error (MAPE), and normalised root mean square error (NRMSE). Monthly ETO estimated by the benchmark method ranged from 2.87 to 5.00 mm day–1. Among the evaluated methods, the Modified Penman method produced the lowest prediction errors, whereas the Hargreaves method exhibited the strongest correlation with the benchmark. Comparison of rainfall and ETO showed that atmospheric evaporative demand exceeded precipitation during most months of the year, particularly during the dry and pre-rainy seasons, indicating the need for supplementary irrigation. Because independent evapotranspiration measurements, such as lysimeter or eddy-covariance observations, were unavailable, the results should be interpreted as agreement with the FAO-56 Penman–Monteith benchmark rather than as absolute model accuracy. These findings provide useful guidance for selecting appropriate ETO estimation methods under data-limited conditions in the semi-arid regions of Ethiopia.

Ethnobotanical study of medicinal plants used in the management of peptic ulcer disease in Igabi Local Government Area, Kaduna State, Nigeria
(”Ion Ionescu de la Brad” Iași University of Life Sciences, 2026-06-12) Ariyo, Oluyinka Christopher
Peptic ulcer disease (PUD) results from an imbalance between gastric mucosal defence mechanisms and aggressive factors. Although modern anti-ulcer drugs are available, many rural communities in Nigeria continue to rely on traditional medicinal plants for ulcer management. This study documented the diversity and ethnomedicinal relevance of plants used for the treatment of PUD in Igabi Local Government Area (LGA), Kaduna State, Nigeria. A cross-sectional survey was conducted among 110 respondents, comprising 36 traditional herbalists and 74 herb sellers selected through random sampling from 4 villages and major commercial centres within the LGA. Data were collected using semi-structured interviews and analysed using descriptive statistics, frequency of occurrence (FO), and fidelity level (FL) to determine the cultural significance of each species. A total of 22 plant species belonging to 17 families were recorded, with Fabaceae (subfamilies Mimosoideae and Papilionoideae) being the most represented family. Ocimum gratissimum (FO: 45; FL: 40.91%), Bryophyllum pinnatum (FO: 40; FL: 36.36%), and Carica papaya (FO: 39; FL: 35.45%) were the most frequently cited species. Leaves (40.91%) and seeds (22.73%) were the most commonly used plant parts, while grinding (33.33%) and decoction (20.83%) were the predominant preparation methods. Oral administration through drinking (54.55%) and eating (40.91%) was the most common route of administration. High FLs indicate strong traditional consensus regarding the therapeutic value of several species. These plants may serve as promising sources of novel gastroprotective compounds. Further pharmacological studies, including bioassay-guided fractionation, metabolite characterisation, and in vivo validation, are recommended to substantiate their anti-ulcer potential and support future drug development.

Evaluation of the effect of a seaweed-based biostimulant on germination and biochemical quality of the species Momordica charantia
(”Ion Ionescu de la Brad” Iași University of Life Sciences, 2026-06-24) Ostaci, Ștefănica; Marta, Alina-Elena; Jităreanu, Carmenica-Doina
Momordica charantia L. (bitter cucumber) is a species of interest due to its nutritional value and remarkable nutraceutical properties. Natural biostimulants, such as those based on seaweed extracts, can help improve plant physiological processes by stimulating germination, metabolism, and stress tolerance. This study examined the effect of the seaweed-based biostimulant Algevit (0.5%) on five genotypes of M. charantia compared with an untreated control condition. First, seed germination was monitored, and then biochemical changes induced by the biostimulant, including the vitamin A (β-carotene), total phenolic, and soluble protein contents were determined. The biostimulant reduced the germination time and increased all three analysed biochemical parameters compared with the control, with the most pronounced effect observed for the vitamin A (β-carotene) content and the Line 1 genotype, with an increase from 3.95 to 8.19 μg/mL, confirming the effectiveness of Algevit.

EUDR in Romania: transfer of good practices to agriculture from the forest sector
(”Ion Ionescu de la Brad” Iași University of Life Sciences, 2026-07-07) Saveliev, Gabriel-Iustinian; Relenschi, Mirela; Buliga, Bogdan; Chelaru Răduc, Maria
The EU Deforestation Regulation (EUDR; Regulation (EU) 2023/1115) extends due-diligence and traceability obligations from timber to cattle, cocoa, coffee, oil palm, rubber, soy and wood-derived products. This is a substantial regulatory shift for agriculture in EU Member States, while the forestry sector has more than a decade of operational experience with its predecessor timber regulation (EUTR; Regulation (EU) 995/2010) and with national instruments such as Romania’s Integrated Timber Tracking System (SUMAL). Aim. This article examines which best practices developed in the Romanian forestry sector are transferable to the implementation of EUDR in agriculture, under what conditions and with what limitations. Methods. A PRISMA-light systematic review of peer-reviewed literature (2015–2026) is combined with comparative policy analysis of Romania, Brazil and Argentina and document analysis of EU, Romanian, Brazilian and Argentine regulatory texts. Six explicit transferability criteria are applied: institutional capacity, technical feasibility, cost, digital infrastructure, smallholder inclusion and legal compatibility. Findings. Parcel-level geolocation, group-ofoperators arrangements, public traceability interfaces, and the combination of mandatory and voluntary controls are largely transferable from forestry to agriculture, but only after substantial institutional adaptation. SUMAL itself displays documented enforcement gaps and traceability fraud, so the transfer concerns governance logic rather than the literal system. Brazil (CAR, SISBOV, Soy Moratorium) and Argentina (RENSPA, SIGSA) offer complementary models for parcel registries and individual identification. Policy implications. Romania offers transferable lessons to other EU Member States, contingent on national forest governance, agricultural structure, administrative capacity and digital infrastructure. Operational priorities for Romania include designating a competent authority under Article 13 EUDR, integrating LPIS/IACS with a national EUDR-DDS gateway and supporting group due diligence through producer organisations.
