This paper aims to expose the many possibilities of using digestate in biogas plants and the advantages of its using. In agricultural animal farms is produced a big quantity of animal manure, which must be adequate managed, mainly as fertiliser. The most advantageous solution of using animal manure and slurry is using it in biogas plants, where, due to degradation of organic matter, digestate is easier to pump and easier to apply as fertiliser, with reduced need of stirring, compared to untreated slurry. The researches made showes that digestate has lower C/N ratio, compared to raw manure. This property means that digestate has a better effect in fertilisation with Nitrogen on short term. The paper also shows the effects of digestate application on soil, compared to compost application of digestate as fertiliser, must be done on the basis of a fertiliser plan. The fertiliser plan with digestate is elaborated for each agricultural farm, according to the type of crop.

Currently in Romania there are farming systems very complex. The complexity of systems is determined by the natural and socio-economic conditions, the development level of the science and technology with the evolution of human society. The literature contains a large number of farming systems and their name is made by one of the specific measures (specific work ) that these includes. The Systems Agriculture widely used and those dominated are: the conventional farming systems, biodynamic, biological and sustainable farming system, that has emerged in the last decade. The need to create sustainable agriculture , that is stable and sustainable and a clean environment has emerged due to the danger caused by the negative effects of chemicalization agriculture. The creating implications of a sustainable agriculture system will allow of the agricultural activities to maintain the natural environment clean and to protect the fragile areas.

The goals of our research were to identify the melliferous base of Vurpăr locality (Sibiu County), emphazing the important aspects, such as: the diversity of the melliferous species, the heating index of blooming (T0 C), the average data of starting of blooming, the honey production (kg/ha), the apical balance. The applied research methods were as follows: observation in the field, the method of direct gathering of different plant species and their identification in the lab. As a result of our researches there was established the taxonomic structure of melliferous flora in the researched area, in this respect being identified 38 taxonomic groups belonging to herbs, bushes or trees, Besides these species of melliferous plants there were identified other 5 tree species without flowers (manna honey) in the area. As a conclusion there can be asserted that the territory of Vurpăr locality holds a valuable malliferous potential. The apiarists dealing with putting into value this territory need to know exactly this potential and also the weather conditions of the area.

SUSTAINABLE DEVELOPMENT IN PUBLIC HEALTH IN THE SOUTH MUNTENIA REGION AND SOUTH WEST OLTENIA REGION

Published in Scientific Papers. Series "Management, Economic Engineering in Agriculture and rural development", Vol. 14 ISSUE 1
Written by Georgiana Melania COSTAICHE, Ioana NICULAE

The purpose of this paper is to highlight sustainable development in terms of health in two development regions of Romania, the South Muntenia region and South West Oltenia region. “Sustainable development is development which aims to meet the needs of the present without compromising the ability of future generations to meet their own needs”. Sustainable development objectives can not be achieved in conditions of ill health, and health is maintained in a functional and a healthy environment. To highlight the evolution of public health in the two regions for regional development and related counties, we used indicators of sustainable development in Romania, based on data provided by the Romanian Statistical Yearbooks for 2011, 2012 and 2013. Indicators used to assess health development in the two regions are: The mortality rate, the infant mortality rate, natural growth rate, hospital beds (per 1,000 inhabitants), population/doctor (per 1000 inhabitants). Research methods applied are clues fixed base and chain base. Factors that increase the mortality rate are represented by a larger proportion of the elderly population, origin, given that rural health services are weak comparing to urban areas.

The Natural complete ecosystem, the original form of development of human society has changed due to the adoption of diversified development options, mainly oriented towards production systems designed to erode the harmony between man and nature. As a consequence of these changes, we are witnessing today an increase of the probability of manifestation of nuisance factors, namely harmful and the vulnerability of human society to their action. The global reaction to this situation, though delayed, is notable and oriented towards the adoption of specific actions intended to produce change towards a environmentally friendly economy. This change, called sustainable development, is a topical issue of maturity and depth and this paper highlights the necessity to successful management of resources for grassland agro ecosystems in order to meet people's changing needs, while maintaining or improving the quality of the environment and conserve natural resources.

This paper aims to study in detail the indicators for characterizing the agricultural holdings in the European Union and in Romania, to highlight the disparities between our country and the countries with a strong assimilation and development of agriculture. Standard gross margin and other indicators calculated for crop and animal production for their use at farm level, required the understanding of their content, the calculation and use in the evaluation activities at farm level. In the European Union, as well as candidate countries to Integration, including Romania, farms are numerous and varied as they are complex reality. To facilitate the unitary analysis of the structural and economic results is necessary to use proper terms.

Published in Scientific Papers. Series "Management, Economic Engineering in Agriculture and rural development", Vol. 14 ISSUE 1
Written by Nicolae STERGHIU, Raluca NECULA, Manea DRĂGHICI

The agriculture development needs measures, and one of the main indicators that quantifies the results obtained is the value of agricultural production. In the present paper is studied this indicator through its structure in the vegetal, animal and agricultural services sector. It is also studied the impact of EU accession on agricultural production value. To capture the structural differences, the results are divided into two periods: the period 2001-2006, representing the period before EU accession and the period 2007-2012, representing the period after EU accession. To these data were added statistical calculations using the mean, the standard deviation and coefficient of variation to determine the homogeneity of the data.

Written by Iulian ALECU, Marian CONSTANTIN, Raluca NECULA

Food problem has been and remains a major concern, both nationally and globally, and the population has or does not have enough income to ensure structural physichological requirements of consumption. In the context of the importance of the role incumbent main categories of food consumption, the paper aims to study the level both total consumption in Romania and derivatives products and cereals, vegetables and fruits. Comparative dynamics shown by appropriate indicators (quantitative physical units and calories) report highlights that resources/total consumption is assured, but the differences in the levels of consumption of fruits and vegetables are considered significant. Consumption aspect qualitative comparisons analyzed by means a reduction in the level of human consumption, but there are slight differences (insignificant) for cereals, vegetables and very sharp significant fruit. For dynamic analysis period can be reported elements of concern, the existence of annual decreases in the consumption of fruit and vegetables.

The economics of two induced breeding methods-hormonal induction and manual stripping were evaluated. In a 1:1 male: female ratio. Three (3) trials were made in each method using spawners weighing 1.5kg each. In the hormonal trial, 0.5ml ovaprim was injected into each spawner and both placed in a breeding tank containing aerated water 10 cm deep. Spawning occurred overnight and eggs incubated at 260C. In the stripping method, eggs were obtained from the female by gentle pressure on the abdomen and fertilized with milt from the macerated testes of the male partner, incubated in another tank containing aerated water 10 cm deep at 260C. Hatching occurred 25 hours later in both tanks. Fingerlings raised were harvested on the 30th day with mean counts of 509 and 3,032 in the hormonal and stripping methods, respectively. Statistical analysis using the least significant difference test (LSD) showed that there was a significant difference (p<0.05) between the mean effect of the treatments. Economic analysis showed a loss of N9,089.00 and a profit of N64,600.00 with mean cost-returns ratios of 0.30 and 1.6 in the hormonal and stripping methods, respectively. It was therefore recommended that farmers use the stripping method in producing Heterobranchus lonifilis fingerlings.
