Counties have expanded the scope of their activities in the economic development process. However, limited research exists of the factors that influence economic growth and development trends of these unique communities. The primary focus of this case study analysis is to determine whether form of government has an impact on county economic growth and development trends while controlling for environmental context and demographic characteristics in Alabama, Pennsylvania, Illinois, and Washington. To empirically test the impact that county form of government and environmental factors have on local economic growth and development trends, ordinary least squares regression is used. The results of this study show that form of government has only a marginal impact on county economic growth and development trends. County environmental factors are found to have a more substantive impact on the economic growth and development trends of counties across these four states.

Plants need certain conditions that represent their living environment. When the living environment provides the conditions required by the plant, it will grow and develop properly. The growth and development of plants involve environmental factors, which represent those constituent elements of the natural environment, which actively intervene in plants’ life. The present work shows the characteristics of an agricultural soil, contaminated with heavy metals (Cu, Pb and Zn) in different concentrations, which has been divided into pots, in which were thereafter planted vegetable seedlings (tomatoes, cucumbers, parsley, spinach, carrots, radishes). During the plants’ growing time, the temperature and humidity of the air inside the greenhouse, as well as the humidity and pH of the soil, were monitored. The growth and the development of the plants under certain conditions were also tracked, until the end of the growing period. The results of monitoring the plants’ growth and development are important in assessing the impact of the contamination over the soil and the plants.

The search for new conditions for growing vegetables in organic crops in order to obtain safe products and in connection with changes in climatic conditions requires an immediate solution. The article considers and proves that the use of biological products affects the formation of highly productive crops and promotes the production of products with a high content of biologically active substances. Studies have shown a positive effect of biological products on the growth and development and yield of beetroot varieties Delicatessen and Red Ball. Studies have been conducted to study the technological aspects of growing vegetables, in particular with the use of biological products, taking into account the environmental impact of both growth processes and quantitative and qualitative indicators. Features of various biological products and their efficiency are analyzed. A comparative analysis of the use of biologicals, which allowed to comprehensively assess the impact of elements of cultivation technology on phenological, biometric, indicators, yield and quality of table beet products, development and improvement of elements of technology for their cultivation in the forest-steppe of Ukraine. This involves the use of highly productive varieties, the use of various effective biological products, is relevant for the spread and cultivation of table beets in the forest-steppe of Ukraine. Phenological observations of canteen beet plants showed that they developed differently and reacted differently in the phases of growth and development, depending on the introduced biological products. The technical ripeness phase began on days 121–129 and was longer than in the control. With the introduction of Solutin and Chlorella – 128–129 days, and in short - with the introduction of biological products Helprost vegetable, Helprost vegetable + Phytohelp, Solutin + Phytohelp – 121–125 days. It was proved that table beet plants differed in height, number of leaves, leaf blade area and their total area per hectare, which compared to the control were from the use of a tank mixture of biological products Helprost vegetable + Phytohelp – 28.3–28.7 thousand m2/ha, which is significantly higher than the control by 13.6–14.8 thousand m2/ha. The area of leaves was slightly lower as a result of the use of other drugs and mixtures – 21.8–22.6 thousand m2/ha. The use of a mixture of drugs Helprost vegetable + Phytohelp contributed to an increase in the mass of the root of table beets by 255–350 g, which is significantly higher than the control by 9–10 g. A positive effect on the yield of beetroot was shown by the vegetable Helprost preparation, as well as a mixture of vegetable Helprost + Phytohelp preparations, the use of which provided a yield of 52.4–63.8 t/ha. The use of a mixture of biological products Solutin + Phytohelp improves the appearance of the plant, increases resistance to harmful microorganisms, and the marketable yield increases to 26.0 t/ha and significantly exceeds the control by 3.2 t/ha.

AbstractThe most critical phase in plant life is seed germination, which is influenced by environmental factors. Drought and salinity are key environmental factors that affect seed germination. Reduction or alterations of germination when seeds are exposed to these factors have been shown to be due to either the adverse effects of water limitation and/or specific ion toxicity on metabolism. Phytohormones are chemical messengers produced within the plant that control its growth and development in response to environmental cues; small fluctuations of phytohormone levels alter the cellular dynamics and, hence, play a central role in regulating plant growth responses to these environmental factors. To integrate current knowledge, the present review focuses on the involvement of endogenous phytohormones in plant adaptative responses to drought and salinity at one of the plant's developmental phases.

Introduction: Many published data on variability of anthropometric characteristics of newborns related to the influence of adverse environmental factors during their antenatal development have been accumulated by now. The purpose of our work was to study the relationship between certain parameters of antenatal physical development of newborns and varying environmental and climatic conditions. Materials and methods: Anthropometric measurements were taken in the delivery room immediately after birth and then assessed against environmental and climatic characteristics of the antenatal period. Results: We established the relationship between the exposure to different environmental and climatic factors, including radiation, during the antenatal period and anthropometric characteristics of the examined newborns. We observed a quantitative variety of signs and found that the body mass was most “sensitive” to the impact of adverse environmental factors. At the same time, the phenogenetic analysis helped establish a significant effect of atmospheric pressure on the body mass. The effects of radiation exposure were, to a greater extent, associated with the signs of influence of both environmental (including the total and ultraviolet radiation – in 57.3 % and 67.8 % of cases, respectively) and genetic factors (in 42.7 % and 32.2 % of cases, respectively). Conclusion: The established genotype-environment effects of exposures to changing environmental and climatic conditions prove the importance of continuing longitudinal observations of the examined infants using a cytogenetic analysis.

Background and Aim: Many environmental factors exist that influence embryonic development which is missing in the poultry industry, such as light in incubation facilities or hatcheries. Light plays an important role in the growth and development of chick embryos, whereas dark environments can lead to hatching failure or embryo distortion. Therefore, this study aimed to demonstrate the importance of light and its various colors on the growth and development of broiler chick embryos. Materials and Methods: Four treatments were used to study the impact of various light colors on the growth of embryos and their neurophysiological traits: Dark without light (D), red light (RL), blue light (BL), and green light (GL), with three replicates per treatment (25 eggs/replicate) for a total of 300 fertile Ross 308 eggs. Each treatment was assigned to one incubator (75 eggs/incubator), whereas all other conditions were kept the same. Results: The results showed a significant increase (p<0.01) in embryonic development for embryo weight, chick body weight, hatchability, and embryo index for RL, BL, and especially GL. RL, BL, and especially GL significantly increased (p<0.01) neurophysiological traits of the neurons, brain weight, and brain index. Conclusion: The use of light during the embryonic period affects the development of the embryo and its neurophysiological traits.
