The paper presents the influence of the conventional and minimum tillage system, the fertilization system and the agricultural year (expressed by different climatic conditions) on the production and economic efficiencyof the soybean culture. The experience poly-factorial, was placed on the type of soil Phaeozem (clay, iluvial) in the Transylvanian Plain (with multi-annual average temperature of 9.1°C and multi-annual average rainfall of531.0 mm). The soybean culture responded favorably to the minimal tillage technology, the production being veryclose to that obtained in the conventional system. The application of the “minimum tillage” system to the soybeanculture requires a fuel consumption of 63.1 l/ha at the price of 328.12 lei/ha compared to the classic technology atwhich 78.6 l/ha is consumed at the price of 412.36 lei/ha, is 84.24 lei/ha in favor of the minimum system.

Urban parks are ecosystems with a dynamic directed by human intervention. Arbuscular mycorrhizal fungi are symbionts with higher plants, with role in increasing the amount of nutrients needed to plant development. In roots, the fungi develops various structures for transfer or storage of nutrients. The grasses developed in the parks of the Cluj-Napoca city present typical mycorrhizal structures, including the two morphotypes of arbuscules. The colonization rate identified in the analyzed samples is over 75%, indicating a high number of propagules in soil. The dependence of arbuscles is higher to intensity than colonization frequency.

This study has examined the response of two species of the blueberry bushes: Elliot and Bluecrop cultivated in the climate conditions of the years 2014 and 2015 to the attack of the Phomopsis vaccinii; we have also testedand determined the biological efficiency of three fungicide products in order to recommend the best of them to be used in the bushes treatment. The attack was calculated by determining the disease frequency (F%) and its intensity (I%). We also calculated the biological efficiency for the three selected products, considered as being the best ones. We utilized the interrupted-linear setting method which consists of 5 plants/three repetitions / product and we monitored 3 plants from each repetition; 2 marginal plants were for untreated control. Our analysis of the two species pointed that the Bluecrop species has a much higher sensitivity against the pathogen than the one discovered in the Elliot species. The calculation of the biological efficiency proved that the best product Funguran OH 50 PW (90,5%) was followed by Alcupral 50 PU (88,8%) and the Copac ( 86,2%) for the Elliot variety, occupied the last place; the same hierarchy with smaller values was found for the Bluecrop variety.

Our research aims to assess the chestnut tree health status in three various locations: Baia Mare, Tauti Magheraus, Baia Sprie, in order to find the most efficient methods to prevent and to combat the bark cancer which develops in the clime conditions of Baia Mare basin. The primary assessment was performed through the determination of the attack degree (AD %), of its frequency (F%) and its intensity (I%) . We took in observation 10 chestnut trees from each location. We determined the number and size of both trunk and branches lesions for each chestnut tree. The intensity of the attack in the three studied areas ranked from the highest intensity 47.5% for Baia Sprie location followed by the intensity of 33.0 % for Tautii Magheraus, to the intensity of 26.5% for Baia Mare. Our analysis performed after the administration of the combat chemical method, we found that this measure was not efficient because the infection did not diminish; thus we recommend the dry chestnut tree elimination, its hygiene cuts, using the biologic combat.
我们的研究旨在评估三个不同地点的板栗树的健康状况:Baia Mare, Tauti Magheraus, Baia sprrie，以找到最有效的方法来预防和对抗在Baia Mare盆地气候条件下发生的树皮癌。通过确定攻击程度(AD %)、频率(F%)和强度(I%)进行初步评估。我们从每个地点取了10棵栗树作为观察对象。我们确定了每棵栗树的树干和树枝病变的数量和大小。3个研究区域的攻击强度依次为:白峰山最高，强度为47.5%;马格拉乌斯次之，强度为33.0%;白海最高，强度为26.5%。我们在使用战斗化学方法后进行了分析，我们发现这种措施并不有效，因为感染并没有减少;因此，我们建议对干栗树进行淘汰，对其进行卫生切割，采用生物对抗。

Work collections are subjected to a renewal process, therefore a regular evaluation is needed inorder to appreciate the genetic advance of the existing variability at collection level and further to identify valuable genotypes in terms of morphoproductive and qualitative traits (protein, starch). The barley intended for brewing must correspond to some qualitative parameters, of which proteins and starch content are of major importance. For this purpose, a study was conducted to assess the variability and heritability indicators corresponding to the two traits at 48 barley genotypes. The genotypes that were the subject of this study were sown in three experimental years 2013, 2014 and 2016. The mean values of 2013 year was 13.71 compared with only 10.77, and 11.27 in 2014 and 2016. The significant value of the heritability coefficient along with the genetic advantage of 0.81 indicates the success of selection work for this important chemical trait.

How do you manage to achieve optimal conditions for growth and development of plants, which can only be achieved through the diversification of soil tillages and and executing their correctness. Moisture and nutritive stress during crop growing, symptoms of nitrogen or phosphorus deficiency are very common in plants grown on compacted land, so production can be significantly reduced.The experiment realized at A.R.D.S. Turda is focused about the influence of the soil cultivation system (conventional and minimum tillage), fertilizer and agricultural year on the soil humidity and yield at maize. In the minimum tillage system the water accumulates in the soil harder but it loses more slowly but comparative with the classic system when accumulates in easier but is lost more quickly. The two years taken into study, 2015 and 2016, were favorable for the realization of corn production so there were yields of over 7000 kg/ha.

One of the main objectives for the future agriculture is to achieve high crop yields but also to maintain and improve soil quality. In 1995, the European Fertilizer Manufacturers Association (EFMA) prepared eight Booklets on Best Available Techniques (BAT) in response to the proposed EU Directive on integrated pollution prevention and control (IPPC Directive). In this Booklet it is show that ammonium nitrate is used extensively as a nitrogenous fertilizer. It is made exclusively by the reaction between gaseous ammonia and aqueous nitric acid, the production of which are covered in EFMA BAT Booklets 1 and 2 respectively. Reseeding of grassland may increase the mineralisation of organic material and lead to a greater amount of mineral nitrogen in soil, which can be leached during the winter-period.

In the wheat crops of central Transylvania a rich complex of phytophagous insects species is reported. Species of thrips, aphids, leafhoppers, flies, cereal leaf beetle and cereal bugs, affects the level of production and quality indicators of wheat grains. In the period of 2015-2016, various integrated pest control models have been applied, watching their effect on the production and quality indicators of wheat, based on applied insecticide treatments, in the experimental lots at ARDS Turda. The results on the quantified production parameters showed oscillations over previous multiannual values, due to the special climatic conditions of 2015 and 2016, to the density of entomophagous and phytophagous insect populations, influenced by the applied treatment system. It is noted that in the years 2015-2016, characterized as exceptional years, with unfavorable thermal and pluviometric conditions, with much higher values than the multiannual average, the gluten and protein content, zeleny index have lower values than in the previous years, at ARDS Turda. The specific annual climate characteristics have a major influence on the production and quality of wheat. Also, pest control strategies have a major impact on the production parameters and qualitative indicators of wheat.

In Romania there are many lands polluted with hydrocarbons, which require decontamination, as they have a significant impact upon the environment and upon the human health. From the decontamination methods, the bioremediation process seems to be quite effective and at the same time it involves low costs. The microorganisms have a very diverse range of metabolic activities for the decomposition of organic compounds that exist in nature. Among the bacteria, Pseudomonas aeruginosa is known to have the best capacity to degrade hydrocarbons. The research activities in respect of the identification of the current pollution condition with hydrocarbons of the soil and groundwater, the exact delimitation of the polluted area which requires decontamination were performed in 2010, on Titu site (in Dâmboviţa county), a former oil products warehouse, but we also took into consideration the previous investigations (2006, 2009). On the soil and groundwater samples we carried out TPH, BTEX, and PAH tests. Following the interpretation of the tests results, taking into consideration the Order 756/1997, in case of soil, respectively the “Dutch List†in case of groundwater it was found a significant exceeding of the limit values. As we knew the pollution concentrations specific to the soil, the exposure ways and the receivers exposed to the effects, the risk assessment study was performed with the help of the RBCA software application (RBCA Tool Kit 1.3a). The risk assessment study showed the necessity of soil and groundwater decontamination on Titu site, as it is risky both for the environment and for the human health. The soil volume we identified to require decontamination was 3.290 compact m3 and the groundwater volume to decontaminate was 3.584 m3.

Meeting the ever-increasing needs of water for domestic, industrial, energy, and agriculture, is getting more and more difficult, due to the fact that water, both groundwater and surface waters are becoming more polluted, this being mostly due to industrial development, population growth, etc. European Council Directive 91/271/2002 transposed by Government Decision 188/2002 is the legal basis of community legislation on wastewater.The biological treatment process uses the metabolic activity of a group of organisms able to degrade organic matter to carbon dioxide and water (Robescu, 2008).
