Concerning the management of durmast seedlings cultures in nurseries, the main methodology applied for enhancing their development and resistance against diseases, relies on the following issues: irrigation, high biological value seedlings, mechanization, disease fight specific chemicals, and, at last but not at least, an appropriate fertilization. The aim of this paper is to identify of the most efficient fertilizing option, in order to form an important variable for increasing the resistance to the powdery mildew attack. The trial was carried on during experimental year 2009 in a durmast nursery from Transylvanian Plain. During vegetation period, the attack degree of Microsphaera abbreviate was recorded. A monofactorial design was put into practice, using 3 variants. Basic statistic and correlations were calculated using STATISTICA v. 7.0. The biggest attach degree of Microsphaera abbreviata on durmast seedlings was recorded in the variant where fertilization was performed with maximum mineral fertilizer dose, N80P80K80 (6.31%), respectively, followed by attack degrees recorded for other mineral fertilizer doses N60P60K60 (5.54%) and N40P40 is classified on the 5th place. Our trial shows that N80P80K80 with poultry manure is the fertilization solution, which confers to durmast seedlings the biggest resistance against the attack degree of Microsphaera abbreviata mushroom.
在苗圃育苗管理方面，提高其发育和抗病性的主要方法是:灌溉、高生物价值苗、机械化、抗病性药剂，最后但并非最不重要的是适当施肥。本文的目的是确定最有效的施肥选择，以形成一个重要的变量，以提高抵抗白粉病的侵袭。本试验于2009年试验年在特兰西瓦尼亚平原的一处玉米苗圃进行。在植被生长期间，记录了短球蝇的侵袭程度。采用单因子设计，采用3个变异。使用STATISTICA v. 7.0计算基本统计量和相关性。以最大矿肥施用剂量N80P80K80的变异株对鸡冠苗的附着程度最大(6.31%)，其他矿肥施用剂量N60P60K60的侵染程度次之(5.54%)，N40P40位居第5。本试验结果表明，N80P80K80加禽粪的施肥方案，能使大竹幼苗对短球菌的侵染程度有最大的抵抗力。

In maize and soybean crops in Romania, have been identified over 40 species of pests, with significant economic importance. Of these pests, particular importance had presented: Ostrinia nubilalis, Diabrotica v.virgifera, Autographa gamma, Agrotis segetum, Amathes c-nigrum, Tetranychus urticae. The monitoring with synthetic sex pheromone traps, by attracting males in mass, was proposed in the 60s of the twentieth century (Knipling & Macguire, 1966). Thus, the method of removal males lead to lower the species population of target insects, contributing significantly to development control insect populations and, thus, to be one of the levers of maintaining the natural balance in contemporary agro-cenoses, that require protection.

In the present study we have monitored particulate matters in different locations in the city of Craiova and Preajba area. We have considered necessary to establish this theme due to the intense traffic, the rehabilitation and modification of public water systems, sewage system and gas network from the over ground and underground passage, and the two CETs from Craiova municipality, which are sources of particulate matter emissions. The measurements carried out reveal a significant content of particulate matters in the Electro Bridge and Km 0 Craiova (urban background), CET I (industrial) and insignificant in the Preajba area. There were recorded daily average and maximum values, as well as hourly values, which were compared with the limit values set by Order 592/2002, there were observed exceedances up to 200% Â from the maximum value allowable.

The plum tree is a fruit tree with fruits that have a very complex content of nutrients many of them still undetermined. In the Reghin area and in Romania this fruit has a significant importance in both industrial units and in smaller households. The present paper has as main purpose the monitoring of the plum plantations and evaluation of frequency (F%), intensity (I%) and the degree of attack (GA%) of the main pathogens observed at that time (2012) in different plantations from Reghin area. The monitoring took place on four plantations with different surfaces by visually estimating four varieties of plum trees De Bistrita, Stanley, Anna Spath and Silvia, with different percentage in the plantations. The symptoms followed on the plum trees were viral symptoms (mottling on the leaves), red spots (caused by Polystigma rubrum) and shot-hole bacterial symptoms (produced by Pseudomonas campestris pv. Plum or Pseudomonas syringae pv. Morsprumorum). These symptoms are very common and damaging in Reghin area, often exceeding the economic damage threshold.

Satisfactory soil fertility is a suitable premise for supplying plants satisfactory development. The aim of this paper was the identification of the role of the most important soil indicators involved in durmast seedlings resistance against powdery mildew attack. A durmast nursery located in Transylvanian Plain was monitored in 2008. Basic statistic and correlations were calculated using STATISTICA v. 7.0. In 2008, a non linear dependence between analyzed parameters was reported. Weak negative correlations between the powdery mildew attack degree and humus (- 0.339), nitrogen (0.346) and phosphorus (- 0.313) were reported. They are representative only in a reduced sample share (11.40%, 11.0% and 9.70%, respectively) and not significant, all characterized by non linearity. By entire experimental period, the correlation between the powdery mildew attack degree and potassium content of soil, apart the other studied correlations, is linear, negative, and very weak, not representative (R2 = 0.004).
良好的土壤肥力是保证植物良好生长的前提。本文的目的是确定最重要的土壤指标在白粉病抗性中所起的作用。2008年，对特兰西瓦尼亚平原的一个杜鹃苗圃进行了监测。使用STATISTICA v. 7.0计算基本统计量和相关性。2008年报道了分析参数之间的非线性依赖关系。白粉病侵染程度与腐殖质(- 0.339)、氮(0.346)、磷(- 0.313)呈弱负相关。它们仅在减少的样本份额(分别为11.40%，11.0%和9.70%)中具有代表性，并且不显著，都具有非线性特征。在整个试验期内，除研究的其他相关关系外，白粉病侵袭度与土壤钾含量的相关关系呈线性、负相关，且极弱，不具有代表性(R2 = 0.004)。

Abstract. Wheat is one of the oldest cultivated plants and most important food plant, the wheat flour bread is the basic food for majority of world population. At the same time the corn crop is affected by many diseases that cause quantitative and qualitative losses. From the many diseases common to the wheat culture, fusarium head blight, produced by species of the Fusarium genus, is appreciated in most parts of the world, as one of the most damaging disease. In addition to losses of production, 10-2 percent in favourable conditions, the flour for bread that came from crops affected by Fusarium is inferior in terms of quality, the bread has low volume and low protein content. The studies conducted have shown the impact of Fusarium infection on dough properties and additional properties for baking therefore a decrease in flour yield and also an increase in ash content in the flour obtained from grain infected with Fusarium observing also a darker colour and an unpleasant odor of flour, protein content and wet gluten increase or decrease after Fusarium infection. Determination of quality parameters, protein, ash and gluten and the production of four wheat varieties in different testing conditions. Study of the Fusarium infection effect on quality parameters and yield was achieved through experiences located in three repetitions. There have been tested four different variants uninoculated - untreated, inoculated - treated, inoculated - untreated, uninoculated - treated on four varieties of wheat Ariesan, Andrada, Apulum and Dumbrava. The artificial infections with Fusarium spp. were made by spraying method according to Ceapoiu and Floare Negulescu, ( 1988 ) and the treatments applied on vegetation were done with fungicides Nativo and Prosaro 460 EC. The testing modality influenced the behaviour of the varieties in terms of production and quality parameters obtained. For all varieties studied, in the variants were applied, vegetation treatment, even though artificial inoculation that have been made high productions were obtained.
摘要小麦是最古老的栽培植物之一，也是最重要的食用植物，小麦粉面包是世界上大多数人口的基本食物。同时，玉米作物还受到多种病害的影响，造成数量和质量上的损失。小麦赤霉病(fusarium head blight)是小麦栽培中常见的多种病害之一，由赤霉病属(fusarium genus)的一种产生，在世界大部分地区被认为是最具破坏性的病害之一。除了在有利条件下10- 2%的产量损失外，由受镰刀菌影响的作物制成的面包面粉质量较差，面包体积小，蛋白质含量低。所进行的研究表明镰刀菌感染会影响面团的特性以及烘焙时的其他特性因此面粉产量会下降，同时从感染了镰刀菌的谷物中获得的面粉中的灰分含量也会增加，观察到面粉颜色变深，气味难闻，蛋白质含量和湿面筋在镰刀菌感染后会增加或减少。四种小麦品种在不同试验条件下的品质参数、蛋白质、灰分和面筋的测定及生产。通过三次重复试验，研究了镰刀菌感染对玉米品质参数和产量的影响。已经在Ariesan、Andrada、Apulum和Dumbrava四个小麦品种上测试了四种不同的变体，即未接种的、未接种的、Â接种的、未接种的。采用Ceapoiu和Floare Negulescu (Â (1988)Â)的方法进行镰刀菌人工感染，对植被施用杀菌剂Nativo和Prosaro 460 EC。测试方式在生产和质量参数方面影响了品种的行为。在所研究的所有品种中，即使人工接种，也采用了植被处理，取得了较高的产量。

The compaction of agricultural soils is a serious problem in the agricultural community due to it’s proven negative effects that can be seen as a form of land degradation. Due to agricultural traffic, applied stresses are transmitted to deeper depths and may alter physical, chemical and biological properties of soils. This paper outlines the structure of a computer application for the assessment of in field agricultural traffic, which is developed as a module within a program for soil compaction control that can be also used as a standalone application that can be installed on any PC or mobile device. The proposed computer application is designed to be used not only as a standalone application but also build in an application for soil compaction assessment. The application is a result of extensive literature and experimental research activities, so it uses proper input parameters data available literature and personal research data gathered by authors of this paper. Following the available studies are defined the input parameters, the general layout of the software application is showed and described, the general structure is analysed and the output data is mentioned. In this paper we designed a software application for agricultural traffic assessment, developed to be as a useful tool not only for in field traffic management but also for soil compaction management on long term, that can be used on small or large farms so the user will have a clear status of the traffic on the field.

Tuta absoluta species originates from South America. It was signaled for the first time in Europe in 2006 in eastern Spain. In Romania it was detected for the first time in the western part of the country into a grange from Satu Mare county in 2009. After a year the attack of Tuta absoluta was signaled into a greenhouse from Curtici city, Arad county. Studying Tuta absoluta reaction at different chemicals and trying to discover which one is the most suitable and efficient to reduce or eliminate the population of the pest. Observations were conducted in greenhouses in Arad. They used different chemicals to reduce or eliminate the pest Tuta absoluta population. Chemicals had a positive effect to eliminate the pest population of Tuta absoluta. If it is discovered in an early stage of the attack, it can be controlled or eliminate by chemicals treatments.

Because young trees are very sensitive to the climatic conditions, special attention must be paid to the environmental temperature. The aim of this study is to emphasize the effect of the low temperature on the spruce young trees within the particular case of Isuica plantation, and the protective effect of solid barriers against frost action upon these trees. The spruce trees less affected by the low temperature (2%) were located the area in the vicinity of the larch curtain bordering the General School building, while the most affected those located at 2 hours of walking (90%). Our study emphasized the vulnerability of spruce young trees against low temperature, and also the importance of placing vegetal and solid barriers, as buildings for protecting them against frost, in areas, which record low temperatures in winter.

Our study emphasized the vulnerability of spruce young trees against low temperature, and also the importance of placing vegetal and solid barriers, as buildings for protecting them against frost, in areas, which record low temperatures in winter.","PeriodicalId":9362,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Rhageletis cerasi (L.) is the most important pest in cherry orchards and it’s attak can affect the quality of fruit on a large percentage (45-100%). The European cherry fruit fly is prezent in all cherry and sweet cherry orchards, therefore monitoring this population is required as an element of integrated protection. The aim of this study is to establish population dynamics in Cluj area. Adult flight was monitored twice a week on yellow sticky panels. Traps were placed in different parts of the orchard. The first captures were recorded in May 29, with a number of 4 adults/orchard and in 24 June we recorded the maximum number, 89 adults/orchard. By monitoring population dynamics we can determine the correct time for application of chemical treatments.
