This paper presents the results of testing the quality of water for irrigation during the growing seasons 2012/2013, in the basin of the Velika (“Great“) Morava River, from Batovac to Varvarin (Gornji Katun), in three monitoring cycles on 20 selected sites belonging to agricultural area under irrigation. It was established that the quality of the surface water corresponded to the standards for irrigation according to pH, conductivity (ECw), dissolved solids (TDS), ion balance: Ca2+, Mg2+, K+, Na+, chlorides (Cl-), sulfates (SO42-), Sodium Adsorption Ratio (SAR). The content of the following trace elements and heavy metals was determined: Cr, Ni, Pb, Cu, Zn, Cd, B, As, Fe, Hg. The obtained results imposed that the contents of trace elements and heavy metals in the studied water samples were in the recommended limits. The obtained results also implies on very strong linear correlation for ECw-B in the studied water samples, and moderate linear dependence TDS-Ni; Cr-Fe; Cr-Ni; Cd-Ni; Cr-Pb; Fe-Ni; Fe-Pb; Ni-Pb. Data analysis revealed that the anthropogenic impact on River Velika Morava water in the investigated area does not affect water quality with a view to its applicability for irrigation purposes. Based on results of analysis of water quality of River Velika Morava it can be concluded that it is usable for irrigation of crops and soil with restrictions and frequent quality checking during the summer months.

THE TWO COMPETING PARADIGMS OF LIBERALISM AND MULTIFUNCTIONALITY IN AGRICULTURE - A UTILITARIAN PERSPECTIVE

Published in AgroLife Scientific Journal, Volume 5, Number 1
Written by Stefan MANN

This paper takes its starting point in Potters finding that neoliberalism, neomercantilism and multifunctionality are the most important discourses shaping agricultural policy. It identifies paradigms that underlie the discourses of neoliberalism and multifunctionality, while neomercantilism can be shown to miss a firm normative framework. The paper uses a utilitarian perspective and concludes in its analysis of the paradigms’ arguments that the realities taken into account for the multifunctional framework are more holistic than for the justification of neoliberalism.

An important percentage of Romania’s agricultural area is represented by degraded agricultural lands that can no longer be used for agriculture but can be ecologically and economically improved. One such method, respectively the use of shrubs, is supported by research conducted in Valea-Sării and Bârseşti experimental perimeters from Vidra Experimental Forest District, Vrancea County. Sustained by the concept of agroforestry, this method is used for the improvement of the degraded lands. In comparison with the ecological exigencies of forest species, there is a great diversity of degraded lands that are suitable for the culture of some species of shrubs. The most affected and unproductive lands (eroded land or landslide) can be improved and enhanced by using sea buckthorn plantations (Hippophae rhamnoides L.). The objectives of this article were to identify the categories of degraded fields that are suitable for the culture of sea buckthorn together with the used forestry amelioration technologies and to emphasize the ameliorative effects and the sea buckthorn culture’s efficiency in regard with site conditions. The research has shown that mixtures of Scots pine (Pinus sylvestris L.) and European black pine (Pinus nigra Arn. ssp. nigra) with sea buckthorn or pine plantations on consolidated lands with sea buckthorn, led to significant increases growth of pines compared to pure cultures of pine, as a result of enrichment in soil nitrogen due to the symbiosis with the mycorrhizal fungus (Frankia). The investigations realized on parcels created especially for the study of leakages and installed on pine and sea buckthorn cultures (Bârseşti perimeter) have proved that the precipitation water leakages is of 4 up to 10 times lower in the degraded pastures and the erosion’s quantum is of 0.05-0.5 mc/year/ha in comparison with over 50 mc/year/ha, in pastures and empty fields. Beside their soil improvement and field stabilization role (by reducing leakages and erosion), the sea buckthorn cultures have also important economic benefits, as their fruits that are highly valued in the pharmaceutical and food industries.

Use landsat image to evaluate vegetation stage in sunflower crops

Published in Scientific Papers. Series "AgroLife Journal", Vol. 4 ISSUE 1
Written by Mihai Valentin HERBEI, Florin SALA

Remote sensing is of great interest for the study and characterization of the vegetation and of the agricultural crops, in order to monitor them and to develop predictable patterns regarding the evolution of the crops and also for the purpose of the decision making process in real time. The main purpose of this research was the study of the sunflower crops dynamics based on spectral information obtained from satellite images. Vegetation dynamics was differently expressed by the indexes NDVI, NDBR and NDMI determined based on spectral information. NDVI has registered an ascending slope since the beginning of the vegetation period until the flowering (65 BBCH code) when the maximum value was recorded (NDVIGS6 = 0.4074). Later the distribution of this indicator recorded a descending slope until the physiological maturity. NDVI in correlation with the NIR band had lower values in the stages 12-14 BBCH code (p<0.01; R2 = 0.642) and 80-81 BBCH code (p<0.01; R2 = 0.605) and higher values at flowering stage, 65 BBCH code (p<0.01; R2 = 0.966), and physiological maturity, 92-97 BBCH code (p<0.01; R2 = 0.993; F = 3148.2). NDVI index has most closely correlated with vegetation phenophases and it highlighted, by the different level of correlation with the spectral information, the dynamics and variability in the sunflower crop.

In order to develop immunoassays for pesticides detection, this work describes the choice of three different haptens that present structural similarity to benzimidazole molecule, methods for coupling them with two carrier proteins in order to make them immunogenic, a protocol for immunization of laboratory rodents with hapten-carrier complexes, and the evaluation of the specific antibody responses against haptens using an in-house developed immunoassay. Three carbendazim (methyl 2-benzimidazole-carbamate) derivatives bearing different functional reactive groups (-NH2, -SH and -COOH), namely 2-(2-Aminoethyl) benzimidazole (AEB),2-Mercaptobenzimidazole (2MB) and 2-Benzimidazole propionic acid (BPA), were coupled to keyhole limpet haemocyanin (KLH) and bovine serum albumin(BSA), respectively, mixed with immuno-adjuvants, and injected four times into Balb/C mice and Wistar rats for induction of specific immune responses.All three chemicals elicited a specific but weak antibodies response upon immunization with hapten-KLH complexes followed by serological testing by indirect ELISA with hapten-BSA complexes, and showed detectabledifferences in antibody titers with regard to number of inoculations, hapten structure and animal species. Whereas the AEB-KLH complex was the strongest, the 2MB-KLH complex was the weakest immunogenic in mice. However, the best animal responders allow the application of technologies for getting monoclonal antibodies against benzimidazoles, which can then be used for immunoassays development.

Strongyle parasites infecting grazing horses have different pathogenity potentials. For this reason, strongyle eggs with horse feces need to be differentiated into small and large strongyle species, usually by means of larval cultivation and subsequent microscopicidentification of third- stage larvae. The present study aims to provide an analysis of the strongyle populations composition based on different morphotypes of third stage strongyle larvae in naturally infected horses. In this regard, a coprological study was carried out to investigate the diversity of strongyle species in naturally infected working horses, in Northeastern Romania. For this, individual faecal samples were collected and examined qualitatively for parasitic infection, using a sodium chloride flotation method, and quantitatively for faecal strongyle egg count (eggs per gram - EPG), by a modified McMaster technique. Further larval cultures were performed from pooled positive samples for the identification of third-stage larvae (L3) of strongyle nematodes. All samples were positive for strongyle eggs,with an intensity rate varying from 50 to 2450 EPG. Larval identification showed mixed strongyle populations, with the following structure: small strongyles (92.9%), represented by the cyathostomin larvae type A (62%), type C (18.6%), type F (8.5%, and Gyalocephalus capitatus (3.8%), and large strongyles (4.5%) species, such as Oesophagodontus robustus (2.6%) and Craterostomum acuticaudatum (1.9%). Out of the total number of counted larvae, 2.6% could not be identified. The present study emphasizes that use of larval cultures allows a proper assessment of mixed strongyle populations in horses and it might represent an useful tool for further investigations into the epidemiology of equine strongyle infections in Romania.

Published in AgroLife Scientific Journal, Volume 5, Number 2
Written by Adrian APOSTOL, Cornelia Ioana ALDEA

The spline interpolation presume to find a set of polynomials of first degree (linear), second degree (parabolic), third degree (cubic), which are defined on an interval, and their connection on the ends of intervals makes, by imposing that these functions has to be continuous on point, to be smooth and without the inflections points. Mathematically presume as their derivatives of first and second order to the left and to the right of point to be in their turn and then continuous. Considering as the limnimetric key (dependence on the level of a river section in relation to the discharge which flow through section) is a smooth curve end with continuous growth (all ensemble that define the general curve must be monotonous), impose the additional conditions on monotony and flexion polynomials and in their interval by operating, not only in connection node of interpolation. If the first derivative of a polynomial is positive on an interval and if the interval which operate the spline polynomial with positive variation of the first derivative, then the spline function in that interval is monotone increasing. If the second derivative of a polynomial spline in the interval of definition a function does not change of sign, and the spline polynomial of interval not present the inflexions, then, the second derivative of a polynomial spline has not the roots in within the interval in which it operates.

WHICH ARE THE MOST IMPORTANT NON-WOOD FOREST PRODUCTS IN THE CASE OF IALOMIȚA COUNTY?

Published in AgroLife Scientific Journal, Volume 6, Number 1
Written by Cristian Mihai ENESCU

Non-wood forest products (NWFPs) represent a veritable resource base for development, providing income to support livelihoods and promoting the competitiveness of rural economies. In Romania, NWFPs are mainly represented by forest fruits, mushrooms, game, and medicinal plants, with a total of almost 350 species of interest. Across the country the distribution of NWFPs is not uniform, being dependent on forests. The goal of this paper was to highlight the most important NWFPs for Ialomița County. Therefore, four categories of NWFPs were selected and 19 criteria were used. The Analytic Hierarchy Process (AHP) was used in order to systematically evaluate both quantitative and qualitative criteria and to assess the performance of selected alternatives (i.e. NWFPs) by means of pairwise comparisons. The analyses were carried out by the aid of the Expert Choice Desktop software. Black locust honey was the most promising non-wood forest product for Ialomița County when all the 19 selected criteria received an equal importance.

Technological and industrial evolution generated an increased demand for natural resources as well as destruction of the global biodiversity at unprecedented rates. Worldwide projections evaluate an extinction ratio of species up to10 times higher than the current rate Up to 2020 EU has establish targets for mapping and assessment of the ecosystem services including all the main stakeholders, covering forests, agro-ecosystems, freshwater and marine ecosystems, urban, arid zones and wetlands. The general mapping approaches for the EU member states involved in the process consist in using GIS instruments and work flows on land cover/land use data through ESRI’s ARCGIS Platform. About 80% of the EU member states have started the MAES process (Mapping and Assessment of Ecosystem Services) at national, regional or case-study level. The essence of the MAES process is to maximize the use of scientific knowledge and technology available in order to make a significant contribution for the ecosystem services and policy decisions to improve and protect biodiversity and life quality, as well as getting an accurate evaluation of the associated costs. The paper integrates scientific data over the MAES targets using Geographic Information Systems by the evaluation of multiple ecosystems types and services, on different temporal stages and synergies in different layers of information. Ecosystems services provide to the human kind nutrition, clean air, water, safety and healthy environment. This is why, mapping and assessing these services would allow determining the direct connections and dependency on biodiversity and its functions.
