During the vegetation period, from April to September, the insects were also collected from the traps, retaining and determining the beetle species.The material was collected periodically, at intervals of about 10-15 days, in total, 10 harvests. Among the collected species we mention: Harpalus calceatus, Dermestes laniarius, Harpalus distinguendus, Anysodactilus signatus, Otiorrhynchus porcatus, Aphthona euphorbiae, Malachius bipustulatus etc
CIRSIUM GENUS IN "ALEXANDRU BELDIE" HERBARIUM FROM "MARIN DRĂCEA" NATIONAL INSTITUTE FOR RESEARCH AND DEVELOPMENT FOR FORESTRY
Get PDFCirsium Genus is well represented in "Alexandru Beldie" Herbarium by 60 species and numerous subspecies. The herbarium, hosted by "Marin Drăcea" National Institute for Research and Development in Forestry, also contains additional information for each sample, such as: the plants` harvesting places, harvesting dates and the name of specialists who have collected the sample. The present paper synthesizes, organizes and presents all the samples of Cirsium genus from this herbarium, taking into account different characteristics stored on plates. The obtained results were then rendered in graphic representations of harvesting periods, in a harvesting map and in a list of specialists who have collected the plants. The introduction contains a short description of the herbarium with the most representative genres, followed by a description of the method used for obtaining the systematization of the Cirsium genre. This was obtained by recording, for each sample, the number and drawer, the collection name, the specialist who collected the plant as well as the harvesting date and place. A conservation degree was also given from 1 to 4, where 1 means a very good conservation degree, and 4 is a very weak conservation degree. The most proliferous period for the herbarium`s development with Cirsium genus species was recorded between 1881-1900. A Cirsium pauciflorum Spr. plant is the oldest plant of this genus present in the herbarium and dates back to 1835, being collected from Călimani Mountains. Cirsium samples have been collected from all Europe with a focus on our country. The conclusions of the paper present interesting aspects regarding Cirsium genus samples from "Alexandru Beldie" Herbarium
RESEARCH ON THE INFLUENCE OF BASIC SOIL TILLAGES AND CROP CARE WORKS ON BIOMETRIC PARAMETERS AND SUNFLOWER PRODUCTION
Get PDFThis paper presents the experimental results of a research carried out on sunflower crop, within the locality of Bailesti, Dolj County. The factors investigated were the basic tillage of the soil and the crop care of the sunflower crop. The basic tillage of the soil that were researched were: year after year disk tillage, without plowing, normal plowing and deep plowing. The crop care works experienced were: one mechanical hoeing, one mechanical hoeing and one manual hoeing and two mechanical hoeing plus herbicide. The paper presents data on the influence of these two factors on the height of sunflower plants, on the diameter of the calatidium, the oil content of the seeds and on the production of seeds per hectare. The best results were given by the deep plowing and the variant with two mechanical hoeing plus herbicide

THE BEHAVIOR OF SOME LOCAL WHEAT VARIETIES IN THE ECOPEDOLOGICAL CONDITIONS OF THE ROMANATI PLAIN
Get PDFFor two years (2018-2019), under the condition of the cambic chernozem argillic-illuvial soil, from S.C. ETCO – MAR S.R.L Cilieni there had been grown the next varieties of wheat: GLOSA -romanian variety and RUBISKO, AVENUE, ANAPURNA-french varieties. Regarding to the production obtained, the Glosa variety has recorded the average value of 6100 kg/ ha, and the Avenue and Rubisko varieties  has obtained an average production of 8500-8800 kg/ ha. Wheat grain protein content largely depends on : the wheat variety, cultivation tecnology (irrigated, unwaterry, fertilization) and the pedoclimatic conditions.A high protein content is associated with a good bakery quality. Among the technological factors, the fertilization influences the wheat protein the most. It is recommended the cultivation of the wheat varieties with a high production capacity, with good resistance to the main climate risk factors in Romania, with good drop resistance and high union capacity, with high ecological plasticty, from different maturity classes, with good tolerance to major foliar diseases, with superior quality indices.Â
CHEMICAL FRUIT CHARACTERISTICS OF FOUR PLUM (PRUNUS DOMESTICA L.) CULTIVARS
Get PDFPlums are among the most consumed fruits in Romania, being a good source of health promoting compounds. The purpose of this study was to determine the chemical fruit characteristics in four plum cultivars. Soluble solids content, reducing and total sugars, acidity and ascorbic acid content were determined. High phytochemicals content was reported for all investigated cultivars. The obtained results show that studied chemical indices vary depending on the analyzed cultivar. The highest soluble solid content (17.08%) and reducing sugars content (4.83%) have been observed in Tuleu gras cultivar. The obtained results recommend all analyzed plum cultivars as having high nutritional qualities
EVALUATION OF GRAIN YIELD AND OF SOME YIELD TRAITS AT DIFFERENT FOREIGN CORN HYBRIDS CULTIVATED ÎN CENTRAL PART OF OLTENIA
Get PDFThe field experiment was conducted during growing season of corn (2019) at the Agricultural Research and Development Station Şimnic - Craiova. This study emphasized on screening different foreign corn hybrids under agro-climatic conditions of Oltenia and to know the adaptability of these hybrids. Twelve foreign corn hybrids (6 of French and 6 of German origin) were evaluated. The yield traits and grain yield were recorded and statistically analysed for comparison amongst the hybrids. The study showed that the corn hybrids within the two sets of different origin (but not between the two sets) were significantly different for all traits analyzed, except for the length of the cob. The highest grain yields among hybrids of French origin were recorded by: ES INVENTIVE (60.74 q/ha) and ES FARADAY (60.02 q/ha) and the highest grain yields among hybrids of German origin were recorded by: KASHMIR (63.79 q/ha), KARPATIS (63.64 q/ha) and BELLAVISTA KXB 643 (63.04 q/ha)
RESEARCH ON THE CHEMICAL CONTROL OF THE INVASIVE SPECIES AILANTHUS ALTISSIMA FROM PASTURES
Get PDFThe present paper presents the results of the chemical control research of the species Ailanthus altissima, an invasive species that damages the lands on which it appears spontaneously, in the form of restricted areas. The total systemic herbicide Roundup, based on glyphosate, 360 g/l was used. Two methods of application were investigated, namely, by brushing on a 30 cm height of the tree trunk and by injection into holes made in the tree trunk. Undiluted herbicide was applied. The first method of application had almost no effect on Ailanthus altissima trees due to the fact that the herbicide cannot be absorbed through the mature bark of the trees. The second method of application gave very good results
PHYSIOLOGICAL PARTICULARITIES OF THE SPECIES VISCUM ALBUM L. ssp.album AND LORANTHUS EUROPAEUS Jack, HEMI-PARASITES ON LIGNUOUS SPECIES FROM THE COMANESTI FOREST, ROMANIA
Get PDF     In the study which had been carried out in the Comanesti forest from the Mehedinti County, Romania, there have been taken into consideration two hemi-parasitic species frequently found in this area: Viscum album, a parasite found on Acer campestre, and Loranthus eurpaeus, a parasite found on Quercus cerris.   During the summer time, the two hemi-parasitic species which have been takes under study show moderate values for the photosynthesis and transpiration, but increased values in the case of leaf respiration.  The leaf suction force presents high values, these ensuring both the absorption and the conduction of brute sap.  The chlorophyll pigment contents indicate higher values in the case of Loranthus, when compared with the other species, Viscum, in the same lighting conditions.   In Viscum album, the water content shows a seasonal variation, with a maximum during the spring time, after the appearance of leaves on the host plants.         In the case of Loranthus, the maximum water content is recorded in early June
RESEARCH OF METHODS OF OBTAINING A VARIED SPEED RANGE OF CONVEYORS USED IN THE FOOD INDUSTRY, BY ADJUSTING THE SPEED OF THE DRIVE ENGINE
Get PDFThe choice of the type of installation depends on the physical-mechanical properties of the load, the direction and length of the route, the nature of the working environment, the technical-economic parameters of the process. The characteristic feature of the transport of materials in the food industry is their large volume and relatively short distance to be transported. This involves a large volume of loading and unloading works, which usually, together with the actual transport operation, takes approx. 20-30% of the total volume of operations performed. The speed of the conveyor is chosen according to the type of products transported, as well as according to productivity. For this reason, it is necessary to design and build modern systems for driving and automating the transport facilities used in the food industry, which ensure a wide range of working speeds
