	abstract = {In this paper, empirical relationships between diameter at breast height (DBH), crown diameter (CD), and stem number per hectare (N) were improved in a Paulownia Shan Tong plantation. Various functions of these variables were defined, focusing on growing space (Gs) and stem number per hectare. The linear crown index between CD and DBH seems to be particularly important in predicting stem number per hectare. Based on an analysis of the relationships, a CD-DBH (R2 = 0.7254) and a DBH-N graphic model (R2 = 0.7302) can be applied widely in plantation forestry. Under suitable site conditions, the investigated Paulownia hybrid can provide a higher increment in DBH than most of poplar hybrids at a certain age. The aim of this study was to explore the relationships between the Gs based on CD and DBH. These types of investigations are of fundamental importance in terms of the growing technology of tree plantations.},

	abstract = {In this study, the growth and physiological performance of four newly bred black locust (Robinia pseudoacacia L.) clones (‘NK1’, ‘NK2’, ‘PL040’, ‘PL251’) together with one registered in Hungary (‘Üllői’) were monitored and compared in a field experiment located in the dry temperate climatic zone of Eastern Central Europe. Tree height and diameter at breast height were measured monthly during May–August 2022, an extremely dry period. Ecophysiological parameters such as leaf temperature, vapor pressure deficit, intercellular carbon dioxide level, transpiration and assimilation rates, and stomatal conductance to water and CO2 were measured in situ. There was a high clonal effect on survival rate and growth of the trees and on the physiological parameters. ‘NK1’ performed best regarding height (1.88 m), while ‘PL040’ (23.76 mm) had the highest diameter increment (n = 16–26). The highest carboxylation efficiency was found in ‘NK2’ (0.077 µmol m−2 s−1), while the lowest was in ‘NK1’ (0.035 µmol m−2 s−1), not showing a significant difference from the ‘Üllői’. Water-use efficiency values were found to be the highest in ‘NK2’ and ‘Üllői’ (4.92 and 4.78 kg m−3, respectively). Ci was found to be maximum in ‘NK1’ and ‘PL040’ (286.15 and 287.37 µmol mol−1, respectively), while it was minimum in ‘Üllői’ (248.30 µmol mol−1). Physiological parameters were found to be significantly different in the clones due to their genetic differences. A strong positive correlation was found between the transpiration and the assimilation rates (r = 0.843–0.994). Within the growing period, the loss of leaves due to abiotic stress was 0 for ‘NK1’ and negligible for the others. ‘NK2’ stood out among the other clones in most of the parameters tested (height, thickness, assimilation, WUE). In addition to its high photosynthetic intensity, its water-use efficiency was also high.},

	abstract = {Remote sensing is an efficient tool to detect vegetation heterogeneity and dynamics of crop development in real-time. In this study, the performance of three maize hybrids (Fornad FAO-420, Merida FAO-380, and Corasano FAO-490-510) was monitored as a function of nitrogen dose (0, 80 and 160 kg N ha−1), soil tillage technologies (winter ploughing, strip-tillage, and ripping), and irrigation (rainfed and 3 × 25 mm) in a warm temperature dry region of East-Central Europe. Dynamics of the Normalized Difference Vegetation Index (NDVI) were followed in the vegetation period of 2021, a year of drought, by using sensors mounted on an unmanned aerial vehicle. N-fertilization resulted in significantly higher NDVI throughout the entire vegetation period (p < 0.001) in each experimental combination. A significant positive effect of irrigation was observed on the NDVI during the drought period (77–141 days after sowing). For both the tillage technologies and hybrids, NDVI was found to be significantly different between treatments, but showing different dynamics. Grain yield was in strong positive correlation with the NDVI between the late vegetative and the early generative stages (r = 0.80–0.84). The findings suggest that the NDVI dynamics is an adequate indicator for evaluating the impact of different treatments on plant development and yield prediction.},

	abstract = {It is difficult to estimate the contribution of individual sources to the total CO2 efflux from soil with vegetation. Long-term experiments with bare soil will provide useful conclusions. In this study, we aimed to mathematize the effect of soil temperature and soil moisture content on bare soil CO2 efflux in a four-season semiarid region to assess the adequacy of different models and to enable future predictions by seasons. We proved that the exponential model adequately described the relationship between the CO2 efflux and the soil temperature. The model calculations showed no significant relationship in the case of an additional quadratic exponential function, while, in the case of the linear model, the homoscedasticity criteria were not met, and the accuracy of the estimation was found to be dependent on the level of CO2 efflux. When the soil moisture content with either an exponential function or power was added to the exponential formula, the models did not provide more accurate results. Our findings confirm that the best-fitting models are dependent on the local environmental conditions, and there are areas in which the moisture content does not significantly affect the CO2 efflux of bare soil. Using trends in historical hourly temperature data in the exponential model, the CO2 emission was estimated to be in the range 772–898 g m−2 y−1 in 2050 in the location we used. Trends in climate change are expected to have considerable effects on the processes that govern the CO2 emissions of soil.},

	abstract = {Wheat is grown in the largest area in the world as well as in Hungary. Globally, the yield is predicted to decrease due to climate change; however, technological development can potentially compensate for it. In this study, the contribution of climatic and technological trends to the change in winter wheat yield in four sub-regions of Hungary with considerable spatial and temporal variations in weather conditions was evaluated. Long-term trends in both the weather conditions and the technology development, with the consideration of the socio-economic circumstances, were identified. For future yield prediction, non-climatic influences and critical climatic factors, as well as sensitivity in the phenological stages, were considered. In the past 50 years, the average yield variation was lower at regional than country scale. Winter wheat yield was not found to be sensitive to temperature, global degree days, precipitation, and climatic water balance, only to heat stress. Considering the technological development and the heat stress during the critical weeks in the last 30 years, an increase of yields can be expected by 2050 in Hungary's western regions (0.72-1.55 t ha(-1)), while yield depression is predicted (0.27-0.75 t ha(-1)) in the eastern regions compared to the values estimated for 2019, +/- 1.5 t ha(-1) within a 95% confidence interval. We proved that yield estimations can show contradictory changes by sub-regions of an agricultural region if the contribution of site-specific technology development, the dominant weather stressor, and the most sensitive phenological phase is involved in the statistical analyses. Identification of the dominant climatic stressor(s) for the different crops is necessary to keep high yield or even increase it under the changing environmental circumstances. Our findings suggest that heat stress is the main concern to maximize winter wheat production in temperate climate zones.},
