Rapid human population growth and its consequences of food shortage become a significant concern in recent decades across the world. The untold reasons behind this food shortage were industrialization, urbanization, modern civilization, etc., where the agricultural land has been deployed. With the decreasing farmland and its cultivation, food productivity declined drastically and failed to serve the world's vast human population. The present challenge is to increase productivity with the least agricultural land. Thus, excessive chemical fertilizer has been used to quickly turn out more outstanding food production, leading to more significant damages to soil ecosystem and human health. Henceforth, bio-fertilizers find the best alternatives to chemical fertilizers. This study focuses on complete nature of plant growth Promoting rhizobacteria, which is used in bio fertilizers for sustainable agricultural productivity and everlasting soil fertility. The characteristics of plant growth promoting rhizobacteria and its role in plant growth and formulation of plant growth promoting rhizobacteria biofertilizers have been revealed through intensive literature. The consortium information collected from various literatures brings the unique findings that plant growth promoting rhizobacteria is the natural boon to the global agriculturist. This study discusses plant growth promoting rhizobacteria bacterial strains' role in protecting the soil from various biotic and abiotic stresses, regulating plant growth and its role in producing biofertilizers. Besides, it is transformed into commercial products. Eventually, the future trends and research in plant growth promoting rhizobacteria bio inoculants that promote sustainable agriculture have been elucidated. The microorganism is the bio fertilizer's main ingredients, promoting the soil nutrients for efficient plant growth and increasing food productivity. Although many microorganisms efficiently contribute to the soil nutrients, this review narrows down to the plant growth promoting rhizobacteria study. Beneficial bacterium plays a vital role in nutrient mineralization and productivity among the various microorganisms. Bio fertilizers containing beneficial bacteria were economically viable and readily available in nature. This review reveals the complete essence of plant growth promoting rhizobacteria and its part in bio fertilizers.

The Lo Go-Xa Mat is a national park in the southeastern region of Vietnam, which has a particularly high biodiversity and it includes different wetlands which are unique diverse in species composition. It can be categorized into two types: temporarily-seasonally and permanently flooded wetlands. Ta Not grassy marsh is representative of the seasonally flooded wetland. Whilst the diversity and ecology of plants and mammals are well documented, little or no information of the benthic ecology in the seasonally flooded wetland exist. This study aims to provide a new database of the nematode’s structure in the seasonally flooded wetland and its relation with environmental variables as well as detection of the ecological quality, considering nematodes as bioindicators. This work is the first investigation on nematodes communities in associate with some environmental variables in the Ta Not grassy marsh. The results showed that free-living nematodes in the Ta Not seasonally flooded grassy marsh are characterized by the high density (ranged from 235.01 to 898.43 inds.10cm-2) but rather low diversity. More specifically, the genus richness (S) ranged from 8.20 to 8.60. The observed Margalef’s species richness (d) was ranging from 1.07 to 1.53 and the Shannon-Wiener index (H') was measured from 2.36 to 2.52. In addition, the Pielou's evenness (J′) ranged from 0.55 to 0.68 and the Hill indices indicated average values ranging between 5.46- 5.84 for N1, between 4.32-4.60 for N2, and between 2.64-2.86 for Ninf. Specifically, our results indicated that deep level, pH, and NH4+ showed a significant correlation with the nematode density and bio-indices. The sediment of the Ta Not grassy marsh was assessed as in good conditions in all stations based on the Maturity Index of nematodes.

This study provides a multidimensional analysis of sustainable socio-economic development and its challenges in the rural areas of Ukraine. The methodology of realization of sustainable development’s conceptual provisions was created. The advantages of using indicative assessment at the regional level were justified. The methodical approach how to define the indicators of sustainable development (including economic, socio-demographic, labor and environmental domains) of rural areas was proposed. Statistical data, experts’ and rural residents’ evaluation were used to assess the level of socio-economic development of rural areas. The proposed system of indicators is applicable not only to the rural areas of the whole region, but also to its different parts. The tracking model is based on the consistent use of economic, mathematical and expert methods: SWOT-analysis, factor, cluster and discriminant analysis. The construction of the dendrogram allows to determine the type of representative for each cluster. The modeling of sustainable socio-economic development for each sample is applicable to all areas within same cluster. A representative sample from each cluster makes it possible to identify the presence in the region of the so-called "points of growth" and to forecast their development. Two scenarios are considered: maximum (the share of GRP accumulation growth 21.2%) and moderate (the share of GRP accumulation growth 10.6%). GDP Gross Domestic Product growth will differentiate by the type of activity: cluster 1 (agriculture, hunting and forestry) 13% increase; cluster 2 (trade, service and household services) 21% increase; cluster 3 (tourism and international cooperation) 18% increase; cluster 4 (processing industry) 8% increase. Therefore, the using of key indicators for monitoring the sustainable development of rural areas provides an opportunity to take into account the specifics of sustainable development of different specialization branches of rural areas that will support high economic and social growth in the future.

The goals of the article are a definition of patterns of change in demand and supply of milk and dairy in the market of Ukraine and revealing the regularities of establishing of partial equilibrium state. The scientific methods which used in the process of the research: simulation was used for defining trends of supply and demand changing and their balancing in the dairy market; economic and statistical method was used for estimation of tendencies of production and consumption of dairy products in Ukraine; analysis and synthesis were used to find out the reasons that determine the trends of supply and demand changes; tabular and graphical methods were used for clearness of the image of the obtained research results; abstract-logical method was used for the formulation of conclusions. Results of the researching: Trends of demand and supply changes in the dairy market in the 2016 year was estimated. Specifics of establishing the state of partial equilibrium in that market were characterized relative to the main groups of its participants as producers and consumers. Development of methodological and practical aspects of features of establishing the state of market equilibrium in the dairy market, unlike existing, is based on a model basis is still actual. The practical significance of those results consists in working out of the tool of justification of managerial decisions for assessing the state and creating regulatory measures for sectoral development.

The sectoral structure of most agricultural enterprises is unbalanced and uncoordinated, which underlies the need in deepened research of its improvement. This paper is dedicated to the formation and evaluation of the sectoral structure with the use of mathematical methods of data processing. Mathematical economic modeling based on optimization and simulation models has been applied for the formation and evaluation of sectoral structure in agricultural enterprises. The approbation of the aforementioned models has been carried out in a certain agricultural enterprise. The simulation modeling has been used to develop a production model by the types of products that enterprise does not produce (milk, fish products and honey). The optimization model has been developed taking into account the rational use of the enterprise’s land with the prospect of livestock sector development. Obtaining the maximum net income (proceeds) from products sales has been chosen as the optimality criterion. According to calculations, the maintenance of cows is unprofitable; the production of fish and honey is profitable. Due to the diversification of the sectoral structure, the enterprise’s profitability level will increase from 16.6 to 45.8 percent. The implementation of optimization and simulation models allows to assess the existing level of sectoral structure in agricultural enterprise and to form its optimal sectoral structure with ensuring the rational use of resources and obtaining profit.

Ukrainian agriculture creates 12-14% of GDP. Ensuring the conditions for sustainable economic development implies the use of adequate mechanisms for regulating economic processes by the government. In the process of formation and implementation of the organizational and economic mechanism of regulatory policy, a system of indicators plays an important role in assessing the impact of such policy on the participants, monitoring and, in case of the deviation from planned results, adjusting regulatory measures. This research analyzes and systematizes the indicators that determine the organizational and economic mechanism of regulatory policy effectiveness in agriculture. The systematization of indicators to evaluate the organizational and economic mechanism of regulatory policy effectiveness in agriculture has allowed substantiating the methodological principles of its integrated assessment. Application of the proposed methodological approach to assessing the organizational and economic mechanism of regulatory policy effectiveness in agriculture in Ukraine was performed during 2010, 2016-2017 period. It revealed slow progress in the organizational and economic mechanism of regulatory policy efficiency during the investigated period. This result is primarily attributed to the lack of purposeful, systematic change management, the lack of mid-term planning, the strictness of most programs, imperfect financial instruments of the organizational and economic mechanism, and procedures for application.

The present study investigates the socio-economic nature of the issue of food provision in the consumer market of Ukraine. It is entity content and main macroeconomic functions oriented at production, sales, and consumption of food, undertaken by the state to maintain the ongoing process of social reproduction and security guaranteeing in the country. It is hypothesized that the change in income of the population, Consumer Price Index, total expenditures of households on food and agricultural production per capita have the largest influence on food provision of the consumer market in the country. Based on the system approach the authors suggest their understanding of the factor determinants grouped by certain features, which influence the condition of food provision of the consumer market in the country. Application of factor grouping method contributed to the identification of parameters that show the links of economic factors and the condition of food provision. Correlation-regression analysis allowed revealing and assessing the dependence of the level of main food products’ consumption in the country on the major groups of factor determinants. The assessment of standardized regression coefficients contributed to determining the input of each suggested factor in the condition of food provision of the consumer market. The strong interrelation between socio-economic factors and the volumes of consumption of main food groups by the Ukrainian population, in particular, vegetable and animal products, is found. The results of the conducted analysis confirm that the condition of food provision at consumer market depends on how efficient the mechanisms of macro- and microeconomic regulation of trade and food policy of Ukraine are.
