The article deals with the effective use of working capital in reproductive process of agriculture and in ensuring its sustainable development, which ensures the growth of the final product production, the improvement of its quality, cost reduction and, as a consequence, increases profits. Entire and timely provision of agricultural commodity producers with material resources and their effective use are necessary conditions for maintaining the production process and increasing its efficiency. However, in reality, the reproduction of the main types of material resources is violated and carried out on a "narrowed" basis. In order to stabilize the reproductive process in agriculture, the authors suggest a model for the efficient use of working capital in agricultural production, based on the use of a multi-stage algorithm that implements an integrated approach to determining the level of efficiency of working capital use in specific conditions.

Sustainable development in rural areas can be identified through a series of projects that highlight both economic, environmental, social problems and measures to improve the quality of life. European standards imposed at local level created opportunities for development and modernization of rural life that raised the level of community trust in European funding instruments. From an economic point of view, it is appropriate to create strategies that include measures and methods of transforming the rural economy into a sustainable and performance focused on innovation. To implement these local strategies, the community will need to implement strategic projects in areas such as health, culture, entrepreneurship, agriculture and education. In the context of the presented ones, the paper constitutes a theoretical and practical analysis of the manner in which the opportunities, phenomena and economic and social processes from the rural area of Galati County must be approached.

To define the peculiarity of sensory perception of offensive smells and "boar taint" by Ukrainian consumers in samples of cooked pig meat and fat from females, surgically castrated males and immunocastrated males. The independent examination of the samples of cooked meat and fat from pigs of different gender and different methods of castration. The hybrids were received from the crossbreeding of Irish sows of Yorkshire × Landrace pig breeds and terminal boars of the “ MaxGrow ” synthetic line. The expertise was conducted for men and women of all ages, who consume pork. Each expert evaluated 15 samples for a qualitative level of the smell for heat-treated meat and backfat. The samples were taken from the right thoracic muscle (m. rectus thoracis) of the right half-body. The evaluation was carried out in accordance with a specially developed five-point scale, which is acceptable for non-professional tasters. It has been found that the smell of skatol can be manifest to the level of its sensory perception by a person regardless of gender and the method of pig castration. The "boar taint” was difficult for precise sensory identification, because the meat of the sexually active boars is not common in porcine production and in processing technology, so most of consumers have never smelt it before. The sample identification for meat and backfat, conducted by men, was more standardized without any particular grade differences. The women decided the samples of immune castrated boars have better smell (with an advantage of 17–22 points). The result of the Ukrainian consumers evaluation of unpleasant smells and "boar taint" detected it in pork. This smell was mainly influenced by two basic factors – the physiological features of the animal organism and the individual peculiarities of the person's perception of a smell. Women and men in different ways perceived the smells of the studied samples. The boiled meat and backfat samples smell of immune castrates was estimated by consumers higher than surgical castrates samples smell was.

The study aimed to evaluate the quality of flowers in daffodils (Narcissus pseudonarcissus L.) in relation to physiological indices and parameters and floral indices. The biological material was represented by five varieties of daffodils: 'Carlton', 'Ice Follies', 'St. Patrick', 'Dick Wilden' and 'Salome'. A series of physiological indices and parameters, and floral indices were evaluated that described the status of plants (plant height - PH, number of leaves - LN, length of leaves - LL), vegetation period (VP), flowering period (FP), and flowers size (FS). The flowering period (FP) expressed in days, recorded the values: FP = 13 days for 'Carlton', FP = 18 days for 'Ice Follies', FP = 9 days for 'St. Patrick', FP = 10 days for 'Dick Wilden', and respectively FP = 11 days for 'Salome'. Correlation analysis revealed very high, positive, correlations between FS and LN (r = 0.968), and between plant height (PH) and leaf length (LL) (r = 0.915). The variation of FS according to LN was described by a polynomial equation of degree 2, under conditions of R2 = 0.938, p << 0.01. A 3D model of FS variation with respect to LN and FP was obtained, and a graphical representation in the form of isoquant, expressed a possible combination of LN and FP for optimum of FS. Principal Component Analysis (PCA) led to the distribution of the studied varieties in relation to the main quality parameters considered (VP, FP and FS). PC1 explained 43.701% of variance, and PC2 explained 39.003% of variance. Cluster analysis led to the grouping of daffodils varieties based on affinity with respect to flower quality indices (FP and FS) under statistical safety conditions, Coph.corr. = 0.924.

In this paper, the quality of the seeds obtained in a company with an agricultural profile, as well as the main factors that can lead to the deterioration of the quality of the seeds, is shown. The company’s headquarter is in Ştefan Vodă commune, Călărași county and owns an area of 1494.43 ha. The period analyzed was 2016-2018. From the crops practiced by the company, we analyzed the qualitative parameters of wheat, rapeseed and sunflower, following the quality of the resulting seeds. Most of the qualitative parameters were within the norms stipulated by STAS. There was exceeding in the case of the hectolitre mass parameter in the wheat crop, but this meant a better quality of the wheat analyzed.

The paper analyzed the concentration of rape cultivated area and seed production in Romania in the period 2009-2018. using Herfindahl-Hirchman Index (HHI) and Gini -Struck Index (GSI), as well the regression and correlation between these indicators. In 2018, Romania had 633 thousand ha cultivated with rape and produced 1,673,327 tons seeds, 2.8 times more than in 2009. All the eight micro-regions are involved in rape cropping. but the largest surfaces are situated in the S Muntenia (39.07%), S E (24.69), S West Oltenia (10.03), West (9.07%). The highest contribution to rape seed output is given by S Muntenia (42.36%), S East (22.89%), West (11.33) and N East (6.43%). The HHI values > 0.25 reflected a relative high concentration of the cultivated area and seed production, mainly in four micro-regions: S Muntenia, S East, S West Oltenia and West. The Gini-Struck Index indicated a moderate concentration of the cultivated area and also of the seeds production, GS= 0.371- 0.468 for surface, and GS= 0.379- 0.477 for production. The correlation coefficient r = 0.888 proved a positive and strong relationship between the two indicators, and the regression model, Y = 2.694 X - 163.83 reflected that one thousand more ha cultivated with rape will produce 2.534 thousand tons seeds in addition. Rape production is expected to continue to grow and to be more concentrated in the micro-regions mentioned above.

The research on the wheat market in the South-Muntenia Region of Romania highlights the dynamics of the main specific indicators for the period 2014-2018. Currently, Romania is an important player on the wheat market in the European Union, because it ranks fourth in terms of wheat production. In 2018, Romania achieved 7.3% of wheat production obtained in the European Union. Also in 2018, the contribution of the South-Muntenia Region to the production made in Romania was of 28.46%. In Romania, significant wheat productions are made due to several factors. Favorable conditions for wheat cultivation are a key factor, which offers the possibility of spreading this crop throughout the country. In the present research, the following indicators were analyzed: the area cultivated with wheat; wheat production achieved, average production per hectare and average purchase price. The analysis of these indicators was performed at the level of the South-Muntenia Region, as well as at the level of the counties that are part of this region. The statistical data that was used in this research was taken from the National Institute of Statistics.

The paper analyses the economic efficiency of the young sheep meat, for the year 2019, as well as the results that can be obtained following the variation of some indicators. The methodology used is the economic analysis, based on the calculation of technical-economic indicators and economic efficiency indicators. The results indicate that for young sheep meat, the total income value is higher than the total expenses by 6.6%. The variable expenses represent 97.2% of the total expenses, and within the variable expenses, the highest share, of 50.5%, is held by the expenses with fodder. The cost per unit of product is 9.4 lei/kg, and the average selling price per unit of product is 10 lei/kg live. If the value of the production increases by 20%, the gross profit increases by 28.6%. The price at the farm gate can vary between 8 lei/kg, if the production value is reduced by 20% and 12 lei/kg when the value of the production increases by 20%.
