Avaldamisel
Avaldamisel artiklid on retsensentide poolt aktsepteeritud artiklid, mis on publitseeritud elektrooniliselt käsikirja vormis, kuid mida pole küljendatud ja mis pole veel ilmunud ajakirja korralises väljaandes. Küljendamine võib põhjustada väikeseid erinevusi võrreldes avaldamisel oleva artikliga, seetõttu võivad publikatsiooni ettevalmistamise käigus muutuda nii pealkiri kui ka sisu.
Highlights:
- Deficit irrigation positively affects water use efficiency.
- High-yielding genotypes are more sensitive to deficit irrigation strategies.
- All tomato genotypes showed different behaviour in response to water stress.
- The Genotypes strategy led to reduced water use in tomatoes.
Highlights:
- Water stress mainly by reducing the sink size and partitioning efficiency of dry matter to grain (harvest index) has reduced grain yield in fenugreek and has less correlation with biological yield and dry matter production efficiency.
- It seems that planting the fenugreek medicinal plant in the agricultural system at a density higher than the natural habitat can be a kind of imposition of density on the plant, which is aggravated in the conditions of drought stress and it is necessary to pay more attention to this issue in research.
- Increasing plant density, first by reducing source strength due to shading, and then by further increasing plant density through sink size restriction, leads to reduced individual seed yield.
Although in some crops, the increase in density under water stress conditions can compensate for the decrease in yield, in fenugreek, the increase in density under water stress conditions was not beneficial for the plant.- Under optimal irrigation conditions and mild stress, there was no difference in chlorophyll fluorescence between different densities, while at severe water stress, high density had a significantly lower chlorophyll fluorescence than low density.






Highlights:
- Observations of the process of ontogenesis in a group of woody plants and forest grass in the phytocenoses of the Ukrainian Polesie of Sumy region with their division into boreal and nemoral species were done.
- Found that in the last two decades, nemoral plant species begin vegetation earlier and pass the first phases of the ontogenetic cycle faster than boreal species.
- Changes in plant ontogenesis, in turn, lead to changes in the population characteristics of plant species: the number of individuals in the population, the size and configuration of the population field and the ontogenetic and vital spectra of populations changed.
- Forest ecosystems are characterized by two processes: change in the floral composition of plant species that form the grass-subshrub layer and change in the composition of forest-forming tree species.
- As a result of these processes, against the background of the loss of competitive advantages, a trend of general nemoralization of forest phytocenoses of Polesie with changes in their floral composition is formed in the group of boreal species.










Highlights:
- The efficiency of growing leguminous and cereal agrophytocenoses (Trifolium pratense and Medicago sativa sown with the addition of Bromus inermis, Lolium multiflorum, Festuca rubra), highlighted their economic and energy advantages over cereal grasses.
- The best indices of economic and energy efficiency are provided by growing alfalfa-cereal grasslands.
- Among fertilizer variants, the highest indices of economic efficiency are provided with the application of Р60K60 in combination with the use of drugs of appropriate strains of symbiotic nitrogen fixation with net profit and profitability of 360–477 € ha–1 and 85–107% with a cost of 1 ton of fodder units 80–93 €.








Highlights:
- Geothermal ventilation provided more comfortable temperatures during warm seasons.
- Geothermal ventilation maintained higher temperatures in the piglet and sow dens during cold seasons.
- Valve-type ventilation provided more intensive air exchange and, as a result, minimized the content of harmful gases.
- Valve-type ventilation created more comfortable air humidity in spring and summer, and geothermal ventilation in winter and autumn.
