Application of bioeffector soil inoculation method development in a pot experinment with tomato

Fertilizers, pesticides, soil disinfectants and other agrochemicals enormously have increased the agricultural productivity recently. Beside the well-accepted positive yield-effects, however, the structural soil-degradation, acidification, decrease of soil life and soil health is also known. Alternative technologies are urgently needed to devel...op for the sustainable agri-, horti-, viti- and silvicultural productions. The beneficial microorganisms, used as biofertilizers, biopesticides and/or soil-vitality products can reduce those disorders; therefore their use is increasing simultaneously. Bioeffector (BE) products, containing vital strains of the beneficial microorganisms might improve the qualitative and quantitative properties of the plants. The effects of BE1 - Trichoderma harzianum T-22; BE2 - Pseudomonas sp.; BE3 - Bacillus amyloliquefaciens Rhizovital 42 F1 were tested in large-pot experiment of using tomato (var. Mobil) in 4 replicates. The BE-s were applied according to the instructions of the producers, in 1 step with the sewing. Before the emergence of the tomato seedlings the BE products was enhancing primarily the growth of the weeds, which is known to develop much faster, than the host. Among the tested bioeffectors, the BE 3, known to enhance P-uptake proved to be the most efficient, both as single and as combined inoculums. Result was comparable with the fertilizer (triple-superphosphate) addition. Study has shown, that the application of BE products might be accompanied more seriously with the used agricultural technology and the physiological properties of the living biofertilizer strains. A second inoculation after the seed emergence and/or the plantation could be highly suggested mainly with BE 3, which might mobilize the hardly available phosphorous in the soil.

EXPLORING NON-VALUE-CREATING PROCESSES USING THE VSM METHOD THROUGH A CASE STUDY OF A SMALL ENTERPRISE’S MANUFACTURING SYSTEM.
Published June 30, 2020

One of the major problems in Hungary is the low level of productivity. This low level is particularly noticeable among small and medium-sized enterprises. In most regional and Western European countries, the average productivity level of enterprises of this size is higher than in Hungary. The current and expected shortage of labor in the near f...uture poses a challenge to businesses. Creating wage growth that contributes to retaining the workforce can only be achieved in the long run by increasing productivity. If an organization is unable to achieve productivity gains, it will fall short of both domestic and international-global competition. The application of modern management and management systems, such as lean management, can be a key element in increasing the productivity and competitiveness of Hungarian small and medium-sized enterprises. Lean management is one of the most common and effective process organization methods and paradigms used in the secondary and tertiary sectors, so much so that the use of lean-based management methods has in many cases become a competitive criterion and fundamental.

In our research, we prepare the value process mapping of a CNC metal cutting SME, including the value process of CNC milling and turning processes. This value process mapping method offers an opportunity to make losses in the industry become known and preventable. Through the preparation of the map, it is possible to illustrate the processes that produce mud and thus reduce the lead time and increase productivity. In the course of our study, we present the practical implementation of the method through the example of a company manufacturing metal parts machined with CNC technology.
