In this paper, some indicators covering milk production, weight gain and feeding efficiency are studied, such as the duration of lactation, total amount of milk, daily amount of milk, percentage of fat, protein, lactose in milk, for a representative sample taken from S.C.D.A Simnic. In the first part, a descriptive statistical analysis is made of the indicators in the zootechnical field presented, followed by econometric methods regarding confidence intervals for the average of the entire population, at a threshold of 5%. Also, the correlation matrix between the indicators is analyzed and three validated linear regression models are presented with the interpretation of the results. These results help to optimize management in the zootechnical field by making decisions based on quantitative analyses. [ABSTRACT FROM AUTHOR]

In this paper, several financial indicators at S.C.D.A. Simnic are investigated from a statistical point of view. Using the method of least squares, the mathematical functions that model the trend are found and with the help of which financial forecasts are made, also using the growth rates with a chain basis and a fixed basis for the time series corresponding to the period 2008- 2022. Finally, an analysis is made of the correlations between these indicators, such as income, expenses, profit, assets, liabilities, stocks, receivables, capital and the results found are interpreted. Thus, the forecasts on the financial indicators and the correlations between them can be of great help in the management of a company, being able to contribute to the efficiency of the activity through adequate budget planning, performance evaluation, investment decision-making or human resources planning. They can help managers identify opportunities and risks, optimize the use of resources, and achieve better financial results for the firm. [ABSTRACT FROM AUTHOR]

In this paper, a statistical analysis of vegetable agricultural production in Romania is made in the period 2009-2021 and a comparative study is carried out regarding the average productions per hectare for certain crops obtained at S.C.D.A. Simnic, respectively in Dolj county and at the national level. It is thus found that there are no significant differences between the average productions per hectare for wheat, sunflower, barley and pea crops from a statistical point of view, at a significance level of 5%. On the other hand, the level of average production per hectare of corn silage and colza in the period 2009-2021 at the S.C.D.A Simnic is significantly lower than at the national level. Comparing the average agricultural production per hectare of oats, it is found that at S.C.D.A Simnic it is significantly higher than the average production obtained in Dolj county and the national level. The work ends with recommendations regarding production management and measures to optimize it. [ABSTRACT FROM AUTHOR]
