MORPHOLOGICAL CHANGES OF ERYTHROCYTES IN HYPOCHROMIC ANAEMIA, IN HUMANS pag. 3-9
Olga-Alina Rada, Diana Brezovan, Mihaela OstanHypochromic anaemia cases are characterised by a deficit in synthetizing and then depositing of haemoglobin in erythroblasts and may result from metabolism disorders or poor synthetizing of any haemoglobin component (iron, protoporphyrin, globin). The microscopic exam of peripheral blood smears correlated with the study of automated complete blood cell counts (CBC) leads to the establishment of an efficient treatment which should correct the occurring deficit. The peripheral blood smears were examined under the microscope, establishing erythrocyte size, aspect and haemoglobin load. We observed shape variations (dacrocytes, ovalocytes, stomatocytes) in variable proportions (12.5-43.75%) as well as erythrocyte diameter variations (anisocytosis) associated with hypochromia. The study of automated complete blood cell counts supported the microscopic observations; the erythrocyte number was 38.5% lower, and the haemoglobin quantity and haematocrit value were 26.84%, respectively 23.75% lower than the minimum values of the reference biological interval.

DownloadTHRIPS (THYSANOPTERA: INSECTA) ON WINTER WHEAT IN TIMIȘ COUNTY, ROMANIA pag. 10-14
Ana – Maria VÎRTEIU1*, Ramona ȘTEF1, Alin CĂRĂBEȚ1 and Ioana GROZEAThrips species have always been some of the main pests in winter wheat crops. Damages caused by this species are either directly by feeding on leaves flowers or fruit, or indirect acting as vectors of viruses. Due to the lack of knowledge on the thrips fauna in western Romania and also the importance of this crop for local farmers, the aimed of this paper is to survey the thrips species associated to winter wheat crops in Timis County, Romania. Thrips were collected from 5 varieties of winter wheat from November to June 2016 – 2017. The monitoring of thrips adults was made using colored sticky traps and the monitoring of thrips larvae was made using the method of ears sampling. The collected material was transported by specific methods in the Entomology laboratory at the Faculty of Agriculture Timisoara. With the help of stereozoom microscope there were determinate the thrips species and also the number of larvae/ear. The most commonly found thrips species was Haplothrips tritici Kurdjumov. According with the present studies, the following thrips species also occur in winter wheat crops, in western Romania: Haplothrips aculeatus Fabricius, Frankliniella tenuicornis Uzel, Frankliniella occidentalis Pergande, Frankliniella tritici Fitch, Frankliniella intonsa Trybom, Limothrips denticornis Haliday, Limothrips angulicornis Jablonowski, Limothrips cerealium Haliday, Aptinothrips rufus Gemelin, Anaphothrips obscures Műller, Stenothrips graminum Uzel, Thrips physapus Linnaeus and Aeolothrips intermedius Bagnall. According to farmers from western Romania, their losses range from 20% to 40% depending on the severity of the thrips infestation. Thrips damage is usually higher during the dry season and warmer temperature.

DownloadTHE ROLE OF COCCINELLIDS IN CONTROLLING PESTS IN WESTERN ROMANIA WINTER WHEAT CROPS pag. 15-20
Ana – Maria VÎRTEIU, Ramona ȘTEF, Alin CĂRĂBEȚ, Codruța CHIȘ and Ioana GROZEAThe insect predator complex in winter wheat crops was studied in order to understand the ecological role played by polyphagous predator in intensive farming system. Is well known that coccinellid beetles (Coleoptera: Coccinellidae) are voracious predators of many insect pest, amoung which can mention winter wheat pests (aphids, thrips). Amoung 5000 species described worldwide, only 23 species are reported in Romania (ANDRIEV & CHIMIȘLIU, 2003). Taking into account the lack of information on this family of extremely important predators, an extensive faunal survey was conducted in winter wheat crop in Timiș County, Romania. The aimed of this paper is to assess the species richness and distribution of coccinellid in 5 winter wheat varieties. Coccinellids were collected from mid April to late July, 2016 – 2017. The monitoring of coccinellids adults and larvae was made using colored sticky traps and direct field counts. Coccinellidae familiy form the most abundent family of predators – compresing 38, 04%. During the investigation 11 species of predatory coccinellids were collected from winter wheat crops from western part of Romania, namely: Chilocorus bipustulatus, Adalia bipunctata, Adalia decimpunctata, Calvia quatordecimguttata, Coccinella septempunctata, Harmonia axyridis, Adonia variegata, Hippodamia tredecimpunctata, Propylaea quatordecimpunctata, Psyllobora vigintiduopunctata and Scymnus frontalis. Adults and larvae of Coccinella septempunctata were the most abundent species found in the study.

aS. KARIMZODA, bK. KODIROVAbstract. The article presents methods to improve the productivity and floristic composition of natural grasslands used as transition pastures in Muminabad district, Tajikistan. In this region livestock is moving annually from winter pastures to summer pastures. The number of the animals implied in this transition is 3 million heads. The author carried out the botanical surveys of the experimental plots with the aim of comparing their modification. Before selecting the experimental plot and set the experiments there has been determined the vegetation of the pasture, considering floristic composition and consumption of natural vegetation. In order to determinate the yield of fodder crops there was sowed sainfoin (Onobrychis viciifolia), alfalfa (Medicago sativa) and a mixture of these legumes with meadow fescue (Festuca pratensis). Before sowing the seeds, the surface of the soil was treated with a Chinese two-wheel tractor (15hp). Sowing of fodder crops carried out in spring time, beginning of February 2018. For the obtaining of fodder crops yield there were used mineral fertilizers as ammophos (N-12P2O5-52) and carbamide (NH2)2CO. Experimental field has a total area of 1800 sq. meter, which was 20 sq meter for each plot. The results of our research showed that the highest yield were obtained from legume – grasses mixture, respectively 7.9 t/ha for sainfoin mixture with meadow fescue..

RECHIȚEAN1)Forage chicory (Cichorium intybus L.) is a perennial species of the Asteraceae family with a wide ecological plasticity encountered in natural grassland ecosystems. The creation of numerous varieties, intended for animal feed, has revealed a number of characteristics of production, quality and resistance to the natural conditions of forage chicory, compared to other species. The researches carried out have demonstrated the potential for high production and quality of forage chicory compared to some perennial legumes species (Medicago sativa, Trifolium pratense, Trifolium repens, Lotus corniculatus). On average, chicory had a production of 6.59 t/ha compared to only 5.12 t/ha obtained by legumes, in non-fertilized variants, and 8.54 t/ha compared to only 5.81 t/ha attained by legumes, in fertilized N100 variants. Also, the crude protein content in chicory was 22.62% in the control (N0) and 25.06% in the fertilized variants (N100), compared to the legumes of 20.31% (N0), respectively, 18.11% (N100).

S. SMETAN1; Dana COPOLOVICI2; Ilinca Merima IMBREA1; Gabriela Valentina CIOBOTARIU1; L. COPOLOVICI2; Georgeta, POP1.Abstract. Chemical composition of lavender oil (Lavandula angustifolia L), produced from lavender cultivated on the experimental site of Morata (Table 1). Lavender inflorescences contain linalool as a major compound. In addition, the chemical composition is influenced by the environmental factors of the growing and blooming period of plants (HASSIOTIS et al., 2014; KIRAN, and BHANU, 2015). We identified 21 compounds in the volatile oils of Lavandula angustifolia L., out of which 14 major compounds (at a concentration of over 0.2%) accounted for 99.53% of the total number of compounds. The remainder of the chemical compounds was found in an amount less than 10% of the total amount. Our results are consistent with other studies on the composition of Lavandula angustifolia L. oil (DUDA et al., 2015, VERMA et al., 2010; DA PORTO et al., 2009). The experimental results obtained in 2016 showed that two chemical compounds, with the highest values, dominate the chromatographic profile of lavender essential oil presented in Table 1: linalool 21.28% and linalyl acetate 18.84%. These major compounds, linalool 21.28% and linalyl acetate 18.84%, are representative compounds of lavender essential oil.

DownloadEXAMINATION OF RELATIVE CHLOROPHYLL CONTENT, LEAF AREA AND YIELD IN MONOCULTURE LONG-TERM EXPERIMENT OF MAIZE IN 2016 pag. 50-57
G. BENCZE, Z. FUTÓIn Hungary, maize has the largest field after the winter wheat. Its 26-27% of all cultivated areas. In the World, the yield of maize were 1071 million tonnes in 2016 (FAO). It is estimated that this figure will grow by 12 million annually. Its main field of use is animal feed, which is about 90% of the yield in our country. The world's population is growing steadily, and this is predicting that the use of food is becoming increasingly important. We reveal the plant physiology and technological contexts in our examinations, that the bases of the modern nutrient solutions, and the scientific bases of the efficient development of the maize growing system The experiment was set up at Szarvas in the experimental field of the University of Szent István, Faculty of Agricultural and Economics Studies, in Galambos. During the research, we examined the effect of various nutrients (N, P, K) ratios on maize monoculture in long-term experiments. The contexts between the factors 64 nutrients we measured it on a supply level, 4 nitrogens portion (0 kg ha-1, 70 kg ha-1, 140 kg ha-1 and 210 kg ha-1), 4 phosphoruses portion (0 kg ha-1, 40 kg ha-1, 80 kg ha-1 and 120 kg ha-1) and 4 potassiums portion (0 kg ha-1, 60 kg ha-1, 120 kg ha-1 and 180 kg ha-1) On the parcels all possible combinations get to a setting, which makes the examinations of the interaction of the nutriment elements. The setting of the experiment onto the bases of the old fertiliser experiment of Faculty on a similar manner, on similar principles, modernized to the scientific and practical claims of our days. We examined the nutrient reaction of maize on the chlorophyll content, the establishment of the leaf area and the average yield. The increase of the leaf area yielded a tight positive correlation with the increase of the average yield and the leaf relative chlorophyll content. From among the nutriment elements we measured the most considerable positive effect in the case of the nitrogen in our experiment. The effects of the phosphorus and the potassium were smaller.

DownloadTHE RESULTS OF THE MODERN DRIP IRRIGATION OF MAIZE IN SZARVAS pag. 58-68
Z. FUTÓ, G. BENCZEThe results of Hungarian maize production are significantly below the yields and total quantity als in the world. Maize yields can be increased significantly if we improve the plant's water supply. To increase the yield of maize in Hungary, we can respond faster with the development of irrigation. The irrigation reaction of maize is excellent, increase on the yield of the irrigation, depending on the year and the amount of precipitation, 10-90%. The proportion of agricultural irrigated areas in the world is steadily increasing, in 2013 has exceeded 325 million hectares, which contributes significantly to the increase in the average yield in the world. The yield of maize can be significantly increased by improving the water supply of the plant. In many areas, only little water is available for irrigation. Traditional irrigation has been switched to drip irrigation in the experiment. Drip irrigation is up-to-date, energy and water-saving irrigation. Energy consumption is only a quarter of its rainwater irrigation. The water consumption of drip irrigation is only half of the water consumption of traditional irrigation. There is not a large evaporation loss and leakage loss. Dropping irrigation is not cheap, but it is very beneficial for water consumption, energy consumption and results in a high yield. The water requirement of maize is not too high, 450-550 mm. Daily water consumption is 4.5-5.5 mm/ha (45-55 m3/ha). The effect of drip irrigation in our experiment was examined for the yield of corn. The experiment was set up at Szarvas in the experimental field of the University of Szent István, Faculty of Agricultural and Economics Studies, in Iskolaföld. The yields increased by 22.3-24.5% compared to the yields of control plots. In our experiment, the growth of the average yield was good for economically. It has been found that drip irrigation can be successfully used in maize producting. The large yields resulted in economical drip irrigation.

DownloadINFLUENCE OF CROP MANAGEMENT ON THE IMPACT OF ZYMOSEPTORIA TRITICI IN WINTER WHEAT IN THE CONTEXT OF CLIMATE CHANGE: AN OVERVIEW pag. 69-74
Otilia COTUNA1, Mirela PARASCHIVU2, M. PARASCHIVU2, L. OLARU2The impact of climate change on specific biotic constrainers like pathogens and on the host-pathogen relationship is associated with changes in pathogens life cycles, increased incidence, pathogenicity, genetically recombination and aggressiveness traits, which require rethinking the integrated management strategies. However, the results of investigations are inconsistent and poorly understood in the context of climatic change. The present review is focused on the influence of crop management on Septoria Tritici Blotch (STB) disease in winter wheat in the context of climate change taking into consideration case studies in order to understand better how the components of disease cycle are affected and to identify disease risk of different agricultural practices. The response of Zymoseptoria tritici pathogen to climate change is of high interest currently in order to estimate disease risk on a large scale and to introduce new understandings in developing management strategies. Soil tillage, crop rotation, sowing date and nitrogen fertilization are considered important tools in disease control which need to be adjusted according with climatically factors for each area which affect the dispersal of ascospores and pycnidiospores of the pathogen. However, further investigation need to be done in order to highlight the impact of climate change on foliar wheat pathogens and which are the most appropriate management tools in order to control these pathogens and to enhance global food security in a changing climate.

Otilia COTUNA1, Mirela PARASCHIVU2, Veronica SĂRĂŢEANU1, Carmen DURĂU1, A. BORCEANIn the western side of Romania appear every year in the maize crops the fungi Ustilago zeae and Helminthosporium turcicum, but the obvious harvest loses appear in the years when are present the optimal limits, the trophic and climatic demands of the pathogen. The objective of this research was the testing of nine maize hybrids original from Italy from the point of view of the reaction to the attack of the pathogens specific in natural infection conditions. The experimental field was placed in the perimeter of the Didactic Station of Banat’s University of Agricultural Sciences and Veterinary Medicine “King Michael I of Romania” from Timisoara. The hybrids were observed during the entire vegetation period in 2015. The nine hybrids with SIS provenance have been tested for the first time in the conditions of Banat’s Plain. The response of the hybrids to the attack of the two above mentioned pathogens was set by analysing the field data on the resistance source scale and on the cultural scale. In the case of fungus Helminthosporium turcicum six hybrids from the experience were showed sensitivity to the pathogen (Kimbos 500, Kampius 480, Pico 450, Sunsis 420, Kabrios 380 and AGN 340) and three hybrids manifested tolerant reaction (Sistema 580, Cristina 600 şi Kalmus 600 – late hibrids). There was noticed in the late hybrids that the virulence is lower comparative with intermediate and ultra early hybrids. According with the cultural scale, less exigent, the hybrids Kimbos 600 and Kampius 480 are maintaining as sensitive and the others are medium resistant to the pathogen. In the climatic conditions of the year 2015 seven hybrids from experience have manifested resistance reaction to the attack of the pathogen Ustilago zeae, respectively Kalmus 600 (130 days), Sistema 580 (180 days), Cristina 600 and Kimbos 500 (125 days), Kampius 480 (123 days), Pico 450 (120 days), Sunsis 420 (120 days) and the hybrids Kabrios 380 and AGN 340 have manifested sensitivity reaction. In general the tested hybrids have tolerated well the pathogen, the obtained results being in accordance with the production company results. The good tolerance to the attack of the pathogens, even excellent in the case of some hybrids, the vegetative vigour and the tolerance to the water stress make possible their successful cultivation in non-irrigated systems and even on soils with lower soil fertility.

Renata Maria SUMALAN 1*, Carmen BEINSAN1, D. CAMEN1, R.L. SUMALAN1Silicon (Si) is the second most abundant element in soil. Previous researches have shown its importance in increasing tolerance to biotic and abiotic stress of crop plants. This paper presents the assessment of the silicon translocation in maize plants grown under specific field conditions, near Gataia town, on uniform background fertilization with macroelements (N, P, and K) and the application of three different doses of exogenous silicon as an aqueous solution: 3, 4, 5 si 6 l/ha by spraying the leaves at two developmental stages: 4-6 leaves and 8-10 leaves respectively, corresponding to14-16 and 19 BBCH code. The silicon content of plants (roots, stem and leaves samples - 10 plants from each variant) was performed at 10 and 20 days after exogenous treatment. The determination of Si in plants was achieved by the classic gravimetric method, of the insoluble and thermally stable form of SiO2. The highest accumulation of SiO2 was determined in roots with 6 l/ha exogenous silicon treatment (ESi), in plant stems treated with 4l/ha ESi and in leaves treated with 3l/ha ESi. This demonstrates that high doses of ESi applied will stimulate accumulation in maize root, and the medium and small doses are accumulated in above ground vegetative part of maize plant.

F. BODNĂRESCU 1, Renata Maria ȘUMĂLAN 1*, S. CIULCA 1, L. COPOLOVICI 2, R.L. ȘUMĂLAN1Tomatoes (Solanum lycopersicum L.) are the world's most consumed fruits, both fresh and processed, and a second important vegetable, after potatoes. The species belong to the Solanaceae family, the genus Solanum and the Lycopersicon section. Besides being consumed in many ways, both fresh and processed, tomatoes have an important role in health because they are an important source of vitamin C, potassium, folic acid and carotenoids such as lycopene and ß-carotene. Carotenoids are pigments synthesized during fruit maturation and responsible for the final colour of tomato fruits. Lycopene is a natural red pigment with significant antioxidant properties involved in reducing the incidence of various forms of cancer. Twelve tomato varieties, comprising four F1 hybrids (round breeding line tomatoes), and the parental forms from which they were created, were evaluated for their lycopene and ß-carotene content using high-performance liquid chromatography (HPLC) and spectrophotometry. Lycopene and ß-carotene content varied significantly among tomato hybrids, with USAB F1 having the highest content of lycopene (33.34 mg/kg of fresh weight) and Banato F1 in ß-carotene (1.59 mg/kg of fresh weight ). Analyzing the behaviour of the hybrids versus their parents, it was observed that for β-carotene the recorded value was close to that of the patern genitor in all the studied hybrids, whereas in the case of lycopene there was no relationship between the values recorded in comparative hybrids with parental lines. The hybrids with high lycopene, ß-carotene has low values and vice versa. The lycopene content analysis shows the Crimson genes are not present in hybrids created by us. Results indicate that genetics may have a strong influence on tomato β-carotene content.

C.PAUNA, Adela AMZA, Laura SMULEAC, A.ȘMULEAC, Alina LAȚOAbstract. Drinking water has become an extremely valuable resource in our century. Corporations have long tried to privatize this vital resource of life and freedom. Slowly new legislative proposals are being made at EU level through representatives of some countries. Underground water should be seen not only as a water tank but must be protected for its environmental value. groundwaters are hidden resources that are much more important than surface waters and for which pollution prevention, monitoring and rehabilitation are much more difficult than surface waters because of their inaccessibility. This hidden nature makes it difficult both to locate and adequately characterize pollution and to understand the impacts of pollution, often resulting in a lack of awareness and / or evidence of the extent of risks and pressures. The main objective of this paper is to determine the quality of groundwater and to present the results of the evolution of the main indicators of the quality of the underground water from the Urseni water treatment station in the period 2016-2017.

Laura ȘMULEAC, Anișoara IENCIU, A.ȘMULEAC, R.BERTICI, R. PAȘCALĂUDischarging of some affluent insufficiently treated has led to the alteration of streams and to the apparition of a wide range of contaminants: organic substances, hardly degradable, nitrogen, phosphor and sulfurs compounds, microelements (copper, zinc, lead), pesticides, organic- chlorinated insecticides, detergents, etc. A feature of the river’s water is the self-cleaning capacity, due to a series of natural biochemical processes, favored by the contact air-water. The self-cleaning process is made by the action of some environment agents, of a physical, chemical and biological nature, which may simultaneously interfere or in a succession order. But when water pollutants overpass the self-cleaning process, wastewater treatment plants are required. In the present paper work it is presented the Timisoara wastewater treatment plant and it is made an analysis of self-cleaning capacity of the waste water treatment plant in 2016 and 2017. One may notice that, after the performed analysis, there is an increased efficiency of the Timisoara city waste water treatment plant by the fact that at the entrance of the waste water treatment plant, values are much above the maximum allowed value, and after the self-cleaning process, values have been much beyond under the limits allowed by the law.
