Abstract This research presents the evolution of the world corn market during 2010-2016. Worldwide, corn crops are a very important agricultural crop, both for the population and for animal feed. In order to accomplish this research, a series of indicators specific to the world maize market were studied. The most representative indicators analyzed in this research are: the area cultivated with corn worldwide; total maize production worldwide; the total amount of fertilizer used for corn crops; yield per hectare for corn crop; the amount of Nitrogen used per hectare for maize crops; the amount of potassium used per hectare for maize crops; human consumption of corn worldwide; net export of corn and FOB export price. The statistical data used in this research was taken from specialized international sites for agriculture and food. In this research several references are made to the future evolution of the world maize market. The forecast period is 2019-2025. Changes that occur on the world corn market are due to several factors, the most representative of which are: the decisions of the main actors acting on this market and the natural conditions. Quantitative statistical methods have been used to carry out this research.

Abstract Cabernet Sauvignon is one of the grape varieties highly suitable for organic cultivation. In the present study, the variety was cultivated in Murfatlar region were both organic and conventional technologies are applied and compared. Also, for each growth system variants with and without 30% cluster thinning were organized. Wines obtained from each variant were compared by the use of an electronic nose. The groups of wines prepared by the same technology were discriminated by the electronic nose in accordance to their volatile profile and on the basis of the discriminating chromatographic peaks determined. The wines produced from grapes conventionally grown were discriminated in two groups by different compounds correlated to the application or not of the cluster thinning operation, while the wines from organic grapes were only slightly separated in groups with or without cluster thinning. However, the wines from organic grapes have shown the highest complexity, as far as the number of discriminant peaks is concerned. Thus, this preliminary study suggests that organic cultivation of grapes may be beneficial for Cabernet Sauvignon wines. The operation of cluster thinning has some effects on the wines made with conventionally grown grapes, but even in this case only 7.6% of the variability in the volatile profile is explained by the cluster thinning. Considering that the grape yield of Cabernet Sauvignon is generally low as compared to other varieties, a further reduction of the grape load may be economically unjustified.

Abstract The loss of a limb through amputation is a traumatic event, leading to major changes in life of a patient. Some of the most cost-effective prosthesis are the myoelectric ones. These rely on sEMG sensors (electromyography) to pick-up electrical signals generated by remaining muscles in the amputation stump from the surface of the skin and relay them under the form of electrical impulses to the command center of the myoelectric prosthesis. We postulate that a higher number of quality signals would result in a higher number of functions for a myoprosthesis to be equipped with. In order to study whether this concept has practical applicability we conducted an experimental study involving the domestic rabbit (Oryctolagus cuniculus) and performed controlled myoplastic transpositions through a fascial breach at the level of the forearm of each subject and tested the intensity of the electrical signal generated by the transpositioned muscle before and after surgery. We evaluated the efficacy and safety of the anesthesia protocol used for this study.

Abstract Using of natural plants as immunostimulant in fish is more useful than antibacterial drugs that cause adversely side effects for fish, environment and consumers. Therefore, the present study was to investigate the effects of dietary turmeric (Curcuma longa), rosemary (Rosmarinus officinalis) and thyme (Thymus vulgaris) as feed additives on growth performance, proximate composition and some immuno-hematological parameters on Nile tilapia. Four nitrogenous (31.43-31.56 % crude protein) and isocaloric (17.90-18.04 kJ/g) diets were formulated to contain 0% (control), 1% of turmeric, rosemary or thyme, respectively. The results reveled that, supplementation with medicinal herbs significantly increased (P<0.05) weight gain, specific growth rates and protein efficiency ratio (PER) compared to those in the control group. Moreover, the medicinal herb additives had insignificant effect on carcass composition and some biochemical composition. Hematocrit and leukocrit levels in the fish fed with turmeric, rosemary and thyme added diet were found to be significantly (P <0.05) higher than the control group. However, leukocyte level among the experimental groups was not significantly differed (P >0.05). In neutrophils of experimental fish groups, there were higher numbers of NBT (+) cells fixed on lamellas than those of the control group. So, based on the current findings together with the low cost and the immunostimulative effect of turmeric, rosemary and thyme it can be recommended to be used in fish feed to minimize the mortalities caused by some pathogens.

Abstract The purpose of this paper is to study and to analyze the chemical composition and energetical value (caloric) of 8 maize hybrids (Fundulea 376, Olt, Bărăgan, P0216, PR35T36, PR35P12, Feria and Rapsodia) tested under field conditions in a farm from, Rovine village, Ialomita County, under non-irrigated conditions, on 2016-2017. For all hybrids the same cultivation technology was applied. Sowing was carried out between April 20-27, for both years, with a density of 50,000 germinable grains/ha and in September were harvested. The analysis of the productivity elements showed that: the average length of cobs was between 20 to 23 cm; number of rows/cobs ranged from 14 to 18; the number of grains/cobs oscillated between 704 grains/cobs at Baragan hybrid, up to 890 grains/cobs at PR35T36; the Thousand Grain Weight (TGW) recorded values of over 300 grams for tree hybrids PR35T36, P0216, PR35P12; the density of plants at harvesting, main factor for yields grains, oscilated from 42,650 plants/ha in 2016 for Olt hybrid to 49.000 plants/ha at P0216 hybrid in 2017; the grains yields was of 8.4 t/ha at Baragan hybrid and 13.9 t/ha at PR35T36 hybrid. Regarding quality indicators of yields resulted: the hectolitre mass averaged 72.7 kg/hl with variation limits of 70.3 kg/hl and 76.8 kg/hl and the moisture varied between 11.90% and 14.50%. Chemical composition is followed: 10.70-12.70% proteins; 3.7-4.3% lipids; 70.00 - 70.70% glucids. Based on these results , it has been calculated the energy values (caloric). This oscillated between 369.3 kcal./100 grams of Rapsody hybrid and 388.38 kcal. of P0216 hybrid. It can be noticed that the year 2017 was a very favorable year for maize crops in the analyzed area, which led to better results for all the productivity elements, grains yields and chemical compozition for all 8 tested hybrids. Also, we can observed the higher energy value on 2017 by comparison with 2016.

Abstract The paper presents the yield results obtained in 2017 for the corn crop grown in the soil and climate conditions of Southern Romania (Calarasi county). The purpose of the research was to analyze the behavior and yield of a range of corn hybrids from different FAO groups: DKC 4590 (FAO 350), PP9911 (FAO 410) and Olt (FAO 430) under different soil tillage systems. The conventional tillage system applied was plowing at 20 and 30 cm, while scarifying at 30 and 40 cm and Tiger 3 MT at 20 and 30 cm were used for the minimum tillage system. The average yield of the three hybrids analyzed was 8,130.3 kg/ha in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding, while for the conventional tillage system without mechanical weeding the yield was 7,682.2 kg/ha. The minimum tillage variants (scarifying and Tiger 3 MT) recorded an average yield of 6,746.4 kg/ha when mechanical weeding was applied and 6,474.9 kg/ha for the variants without mechanical weeding. Regarding the degree of weeding by tillage system, in the conventional tillage system (plowing at 20 and 30 cm) with mechanical weeding the number of weeds was 4.2 plants/m2 and 9.3 plants/m2 for the variants without mechanical weeding. The minimum tillage variants (scarifying and Tiger 3 MT) recorded 12.8 weeds/m2 when mechanical weeding was applied and 16.2 weeds/m2 for the variants without mechanical weeding.

Abstract The perception of landscape and consumption behaviour in relation to landscape was estimated using a questionnaire-based survey with 17 photographs: 15 photos from Romanian representative landscape units, 1 photo representing a foreign landscape (Hungary), and 1 marketing photo. The photo documentation was conducted in sixteen vineyards ecosystems from Târnave Viticultural Region - Transylvania (NW-Romania). The most representative landscape was the photo that had the specifications and criteria: low practices intensity with low landscape complexity; and the less representative landscape was the photo that had the specifications and criteria: photo capturing hiking, walking, tourism, and recreational activities in a viticulture landscape. The landscape could influence the following aspects of communities’ livelihood: establishments and development of enterprises, tourism and recreation businesses, and the place to live. The words used by interviewed people to point out the landscape were interpreted from the point of view of the concept of multifunctionality.

Abstract Jerusalem artichoke tubers (Helianthus tuberosus) are distinguished by their protein, minerals (potassium, calcium, magnesium, iron, etc.) and inulin content. Inulin can be used in the diet of diabetics as a substitute of sugar, without having an impact on blood glucose. At the same time, an international study had shown that due to their inulin content, regular consumption of Jerusalem artichoke tubers can help to prevent type 2 diabetes. In this paper are presented the results of the researches performed to achieve a functional ingredient (powder) with high nutritional value by processing of Jerusalem artichoke tubers. Thus, the Jerusalem artichoke tubers (Red Jerusalem artichoke and White Jerusalem artichoke varieties) were subjected to a convective drying process at 50°C, to protect bioactive components (vitamins, phenolic compounds, etc.) to a moisture content that allow their milling and turning them into powder and, at the same time, their stability in terms of quality. The achieved functional ingredient was evaluated sensory, physicchemically and microbiologically. The powder obtained from Jerusalem artichoke tubers is characterized by their inulin-type fructans (51.60... 57.45%), crude fiber (6.85...8.27%), total polyphenols (18.51... 44.03 mg GAE/g), proteins (8.75...9.26%), iron (12.45...13.88 mg/100g), potassium (1905.44...2100.35 mg/100g), calcium (50.21...57.45mg/100g), magnesium (84.55...89.95mg/100g) and phosphorus content (300.12...345.35 mg/100g). At the same time, powder achieved from Jerusalem artichoke tubers has antioxidant potential. Due to its complex biochemical composition, the functional ingredient achieved from Jerusalem artichoke tubers can be used to fortify food and also as a sweetening agent for products destined to diabetics.

Abstract The global climatic changes consisting of the increased in the average air temperature and changes in the rainfall regime have led in the last decades to the extension of the agricultural areas affected by the drought phenomenon, both worldwide and in Romania. During the last half century, the drought and the phenomena associated with it, namely aridization and desertification, are a major problem for mankind. The limiting factor affecting field crops on the largest surface is the drought, the extent and intensity of this type of risk causing annual reduction of agricultural production by at least 30-50%. Drought represents the natural phenomenon determined by the amounts of precipitations below the normal values. The absence of rainfall is due to the predominance of the anti-cyclonic type. The most frequent phenomena occur in the extra-Carpathian agricultural regions of southern and south-eastern Romania Muntenia is located in the drought-sensitive area, where the influx of continental anti-cyclones is higher. Although this phenomena is possible in all seasons and in all agricultural areas, it doesn’t occur simultaneously and doesn’t have the same intensity. In the 21st century, the agricultural years 2001-2002, 2002-2003, 2006-2007, 2011-2012 and 2014-2015 are included in the list of the most recent years in terms of rainfall quantities, the heat units recorded in the warm season, as well as the soil moisture reserve available to winter wheat and maize plants during maximum water consumption. The objective of this paper is to highlight the correlation between the pluviometric regime analyzed during periods of maximum consumption of water from winter wheat and maize crops, the phenomenon of "heat" and the soil moisture reserve. The analysis of these specific indices helped us characterize the mentioned agricultural years, in the context of analysing the phenomenon of pedological drought with an impact in agriculture in Muntenia Region. An important element in the development of agricultural management strategies is to improve scientific knowledge and capacities to better manage climate variability by examining climate data and risks and opportunities analysis. The decrease in production of winter wheat and maize wheat crops occurs in extreme dry agricultural years due to the shortening of the vegetation season as a result of the increase in air temperature and water stress during the period of accumulation of the dry matter in the grain (the filling phase grain) caused by the reduction of precipitation amounts. Drought periods are increasingly common in Romania and are a major problem for agriculture with high impact on the agricultural production.

Abstract Currently, the blueberry crop systems are continuous diversifing due to the growing demand for fruit on the market as well as the willingness of farmers to invest in profitable blueberries business. The need to extend the fresh-consumption period of blueberry fruits has made crop protection systems be considered appropriate for high-quality and valuable fruits. In the present work, we have proposed to compare the economic efficiency of three blueberry production systems as follows: the normal intensive cultural system in beds, the superintensive cultural system in pots and the superintensive cultural system in pots and plastic covered (high tunnel). The analyze of the cost and profitability of blueberry has been done according to the crop system, taking into consideration several elements such as: the number of plants per hectare, the total duration of the exploitation, the value of the investment, the yield and the cost of production etc. Further more, considering the average sale price of the blueberry fruits in Romania, we have calculated the net annual return, the annual return rate, the cost recovery period, total operating profit, economic return on investment, and average return on investment. We observed that as much the degree of intensification has increased, the value of investment was higher and the spendings has increased too. Blueberry pot production systems with or without plastic protection are especially recommended for smaller surfaces, which in this way can boost the value and their economic potential.
