Sowing date is a particularly important management option to optimize yields as it determines proper wintering and productivity. During a seven-year field experiment, the response of winter wheat to five different sowing times was studied. The beginning of the dormancy period was determined, and the Growing Degree Day (GDD) requirements for the per...

Harnessing wind energy in Lithuania is one of the most important ways to implement climate mitigation measures. This study aims to assess whether it is feasible to implement an energy greening plan in Lithuania in the 21st century, hypothetically by using only wind farms, where the entire permitted area is developed with them. The wind turbine chos...

It is essential to understand how climate change and varieties affect crop phenology and yields to adapt to future climate change. The aim of this study was to analyse the phenological development trends of three winter wheat cultivars (1990-2020) to identify the most critical meteorological-climatic factors influencing the development and yield of...

Field experiments were carried out at the Experimental Station of Vytautas Magnus University Agriculture Academy in Lithuania (54° 53' 3.26", 23° 50' 33.25") during 2017-2018. Six winter wheat varieties were studied in the experiment: 'Skagen' (control), 'Julius', 'Edvins', 'Artist', 'Aron' and 'Evina', which were sown on September 15. Preceding cr...

Wind energy is one of the most important ways to implement green energy in Lithuania. The development of wind energy infrastructure by state funding is directly related to wind energy resources. Changes in wind energy resources induced by ongoing climate change have not been well analyzed either in Lithuania or in Europe or worldwide. This article...

Developing wind energy in Lithuania is one of the most important ways to achieve green energy goals. Observational data show that the decline in wind speeds in the region may pose challenges for wind energy development. This study analyzed the long-term variation of the observed 2006–2020 and projected 2006–2100 near-surface wind speed at the heigh...

Though the number of climate-change-related agro-phenological investigations are growing rapidly, the attention paid to spring crops has been much less than to winter ones. The objective of the current study was to investigate long-term temporal and spatial trends of spring barley phenology and to project changes in the timing and duration of diffe...

This study aims at estimating the influence that climate change is expected to have on the energy performance of a residential building in Kaunas, Lithuania, primarily due to changes in heating and cooling demand. Projected temperature data of IPCC (Intergovernmental Panel on Climate Change) representative concentration pathways (RCP) 2.6 and RCP 8...

Climate warming and a shift in the timing of phenological phases, which lead to changes in the duration of the vegetation period may have an essential impact on the productivity of winter crops. The main purpose of this study is to examine climate change-related long-term (1961–2015) changes in the duration of both initial (pre-winter) and main (po...

The analysis of long-term time series of spring phenology for different deciduous trees species has shown that leaf unfolding for all the investigated species is the most sensitive to temperatures in March and April and illustrates that forcing temperature is the main driver of the advancement of leaf unfolding. Available chilling amount has increa...

The variability of solar irradiance is the most important issue that determines the reliability of solar power generation in short-term time scales. For long time scales the energy produced by solar irradiation has to be predicted with high certainty. However, environmental parameters such as global temperature, precipitations, cloud cover have cha...

Wind energy is an auspicious technology which helps to transform today's society to the use of environmental friendly energy. However, sound emissions from wind turbine have been one of the most important challenges in wind energy engineering. As technology has advanced, wind turbines have become quieter, but sound from wind turbines is still an im...

The aim of the study is to analyze the noise impact of road traffic flow to the noise levels in the vicinity of wind plant. The road A11 Šiauliai-Palanga and the wind plant near Vydmantai were chosen for the study. Noise levels were measured downwind, upwind from the wind plant and upright to the road. It is shown that the wind plant noise at the d...

The erosion of W coatings with the different content of C was investigated in Ar and At + H(2) plasmas. The enhanced erosion was registered in At + H(2) plasma for coatings containing 40 at.% of C and more, which might be owing to chemical erosion of carbon. The erosion kinetics was analyzed together with the studies of coatings microstructure, pha...

We have studied experimentally the distribution profiles of accommodated oxygen and hydrogen atoms in Mg–Ni films after different stages of hydrogenation at 8 bar pressure in the range of temperatures 210–250 °C by Elastic Recoil Detection Analysis (ERDA) and Nuclear Reaction Analysis (NRA) techniques and performed X-ray diffraction (XRD) structura...

A model to account for the mobility of radiocesium in soil is presented. The model requires a minimal set of coefficients that describe radiocesium migration and fixation rates, which can be related to physical soil properties. The peculiarities of experimental radiocesium profiles in soil are explained by the composition of soil, which affects the...
