Objective. To study the effect of mycorrhizal preparation "Rizomax" on the basis of an endomycorrhizal fungus Glomus sp. on the growth and development of the root system of the grape plant.Methods. The studies were conducted from 2016 to 2018. The influence and aftereffect of mycorrhizal drug on the root system and growth of the grape bush were studied in the Eastern viticultural district of the South Coast zone of the Crimea. The studies were carried out according to the generally accepted methods used in viticulture.Results. The advantage of introducing mycorrhizal preparation when planting in the zone of the root system is established, in this regard, more intensive growth and root formation occurs, as well as the growth and development of the grape bush improves. The influence of the aftereffect of the studied preparation on grape plants is estimated, it is established that in experimental variants the development of plants occurs more intensively. Due to symbiosis, the grape plant more effectively uses moisture and nutrients accumulated in the mycelium, which is reflected in the improvement of phytometric indicators and high aging of the vine.Conclusions. When conducting studies in 2017-2018, to study the aftereffect of the mycorrhizal preparaion "Rizomax", in the experimental version, a stable excess of growth processes by 38.3% 43.8% and the leaf surface of the bush by 34.5% 41.7% over the control version was established. The ratio of different fractions of roots in the experimental version compared to the control is more favorable. The fouling part of the root system is 2.53 m according to the measurements of the roots, you can see how much soil the roots of the grape bush covered, that is, in the experimental version, the absorption capacity is higher. Well-developed root system and leaf surface provide further, high productivity of grape bushes. Therefore, for good plant nutrition, it is important to maintain a correlation between the root system and the leaf surface.

The results of our studies and the data of modern literature regarding the biological role of Cr(III) compounds in conditions of their application in the nutrition for pigs and cattle are discussed. The metabolic impact of Cr(III), coming from different sources – mineral and organic compounds, obtained by chemical synthesis or a nanotechnological method (chromium citrate), as well as in the form of biocomplexes from the cultural medium of Saccharomyces cerevisiae yeasts was analyzed. The metabolic connection between the impact of Cr(III) and the biosynthesis of some hormones – insulin, cortisol – as well as the sensitivity of some tissues and organs to the effect of chromium compounds was studied. A considerable part of the review material was dedicated to the metabolic effect of Cr(III) compounds on the reproductive function of pigs and cattle and their impact on the viability of the offspring and gametes of animals. The data about the stimulating effect of Cr(III) on the growth and development of the organism of piglets and calves, meat and milk performance of these species of animals are discussed. The relevance of dosing Cr(III) in the nutrition of pigs and cattle is highlighted.

Aspects of human growth and development have been studied since the inception of psychology as a field of science. The impact of the quality of mothering on children has been highly researched. However, little attention has been paid in the professional literature to the experiences of mothers as their children move through developmental stages. The focus of this hermeneutic phenomenology study was to investigate how mothers’ experiences of their child's growth and development changed her perceptions of her identity and herself. Participants were eight women who had launched the oldest child from the home within the last 2 years. Extensive data analysis and triangulation procedures were conducted to develop themes. Universal themes experienced by all participants were categorized as internal (questioning, comparison, being purposeful, and feeling supported) and external (experiencing joy). Some participant experiences were influenced by incidental themes such as subsequent children, expectations versus reality, and spirituality. Participants’ experience of their mothering role was also impacted by the process of letting go through the developmental progression of their children. Clinical implications are discussed.

Currently the development of children is the center of attention for families and schools, where at this time technology or social media in the current digital era has a very good and bad impact on children if parents and teachers do not monitor children in using social media. the impact of the misuse of technology, it must continue to guide children. Education in schools is very helpful for the growth and development of children. Because children who receive education at school understand more about some of the things that can be learned at school and children's behavior is more functional because it is shaped by observation and influenced by what they get. When parents or teachers educate children well, the child's association will be better. Because nowadays, especially the use of technology or social media, it really has an impact on children.

One of the most important demands imposed by the consumer market on the Brazilian Productive Chain of Flowers and Ornamental Plants is the constant launching of innovations in cultivated species and varieties. Such innovations include the constant introduction of flowers and plants not yet grown and commercialized, both native and adapted exotic species, as well as transformations and changes in size, shape, coloring and conduction patterns and presentation of these goods to the market. Brazil does not have a relevant breeding and cultivation industry. In this sense, it is highly dependent on imports of genetic material developed by countries such as the Netherlands, Germany, Japan, the United States of America, Thailand, among others. Recent developments in the sectoral policy to protect the rights of genetic developers, in the development of internationally adequate legislation and in the control of the use and trade of cultivars, has allowed Brazil greater access to new genetic materials of high quality and in line with contemporary international trends in the consumption. This article aims to discuss the state of the art of protection of cultivars in Brazil, pointing to the advances that the legislation and the inspection have allowed in relation to the introduction of genetic innovations, evaluating the impact of these measures on the growth and development of the market of consumption of flowers and ornamental plants in the country.

Sandpits are commonly found in playgrounds but in a world full of high-tech entertainment is their role in the developmental growth of young children undervalued? Professor Hiroyuki Kasama, Doshisha Women's College, Japan, is exploring the impact of sandpits on children, including the role they can play in deepening the relationship between parent and child. Sandpits first came about in Europe in the mid-19th century but have recently become unfavourable to many parents who consider them to be 'dirty' play. However, playing with sand yields important benefits, including the use of natural materials and the fact it provides a valuable sensory experience that enables children to build on emotional, social and athletic skills. Kasama is investigating the important potential of sandpits as well as working on childcare and education programmes that use sandpits for learning. Kasama is keen to improve the sandpit environment by standardising the type of sand used in order to make play more effective and observing the suitability of the sand by observing children's play and the reactions of their caregivers. Kasama and the team have also supervised the installation of indoor sandpits that can be used year-round. Ultimately, by clarifying the significance and necessity of playing with sand and discovering its potential, Kasama is aiming to provide children with effective environments that promote growth and development.
