Considerations about the Influence Factors on the Competitiveness of SME’s from Western Region of Romania

There are many ways in which the firm competitiveness can be understood in the related literature. The purpose of this research is to undertake a better understanding of expectations and concerns of small and medium sized enterprises from Romanian Western region, in term of competitiveness. This study presents preliminary results of a finished grant focused on SME’s competitiveness. There are some positive and negative factors in our research which are influencing firms’ competitiveness. This study has confirmed our hypothesis. The external environment influence on the competitiveness of SME’s is strong and contributes decisively to their performance.SME’s, competitiveness, growth, external factors, Romania

The variation of some vegetation indices of maize under the influance of mineral fertilization

The present research studied the variation of foliar area and chlorophyll in maize under the influence of mineral fertilization. The fertilizers applied were nitrogen, in doses that varied from 0 to 200 kg a.s. ha-1, and the PK complex indoses between 0 and 150 kg a.s. ha-1. The vegetation indices were studied in the leaf opposite the ear, and the determinations were made during the silking stage. The foliar area varied between 513.88±16.47 cm2 in the control variant and 724.32±13.61 cm2 in the variant with P150K150N200. Chlorophyll values ranged from 30.74±0.89 to 55.93±0.73 SPAD units in the same variants. The experimental results present high degree of statistical certainty (p> F crit, for Alfa = 0.001). The interdependence identified between the vegetation indices and the fertilizer doses was revealed by statistical-mathematical analysis (correlations and regressions) as well as by graphical representation

The relation between productivity elements and mineral fertilization in wheat

The present research deals with the relation for determining productivity elements based on differentiated fertilization of wheat. Ear length and spikelet number presented smaller variation amplitude, while grain number and the weight of the grains on the ear had greater variation under the influence of differentiated fertilization. The differences in the productivity elements under analysis have statistical assurance and high degree of certainty (

The contribution of magnetic fluid to the variation of the chlopophyll content in wheat

The present research focused on the contribution of water-based magnetic fluid to the variation of the chlorophyll content in wheat by application associated with urea. Urea and magnetic fluid in various concentrations determined variations of the chlorophyll content in wheat plants, within the limits of 52.73±0.15 - 57.10±0.12 SPAD units, 48 hours after the treatment (R2 = 0.955,
