In the years 2015-2016 in Sahryń (50°41′ N, 23°47’ E) a field experiment, with the aim of assessing profitability of foliar nutrition of sugar beet with silicon, was carried out. The following products containing silicon were used in the experiment: Actisil, Herbagreen Z20 and Optysil. Each of them was applied once, twice and thrice. For each combination, the gross production value, the costs of foliar nutrition, the net production value and the profitability index were calculated. The total costs of silicon foliar application varied depending on the number of treatments and the applied product from 50 to 402 PLN/ha. The gross production value of sugar beet due to foliar nutrition with silicon increased by 1.3-22.9% for the research period, and the net production value by 5.5-19.0%. A large variation in the achieved financial results was observed in 2015, in which there were particularly unfavorable conditions for the growth and yield of sugar beet. In the more favorable year for growing sugar beet (2016), the difference was smaller. The largest increase in the gross and net production value of sugar beet was ensured by the double and triple application of Actisil fertilizer and the triple application of the Optysil growth stimulator. However, the largest profitability indicator (11.26) was characterized by a single Optysil growth stimulator application.

Epidemiological studies were carried out on 135 isolates of Staphylococcus aureus strains originating from medical staff, patients, and hospital environment. Restriction fragment length polymorphism (RFLP) analysis revealed genetic diversity of S. aureus isolates. Some clones were transmitted among nurses, doctors and patients. Our studies also demonstrate contamination of the hospital environment with S. aureus strains and there is a possibility that the patients acquire staphylococci from the environment. Moreover, we found that many medical staff workers were colonized with S. aureus and the transmission of these strains to patients is possible.

In 2010-2012, in Sahryń (Lubelskie Voivodeship), a field experiment was carried out, the aim of which was to assess the cost-effectiveness of foliar nutrition of sugar beet with marine calcite Herbagreen Basic containing silicon. The fertilizer was applied in two variants: 1) 1 kg/ha at the 4-6 leaf stage of sugar beet (BBCH 14-16) + 2 kg/ha 21 days later; 2) 2 kg/ha at the 4-6 leaf stage of sugar beet (BBCH 14-16) + 2 kg/ha 21 days later; the effects were compared with the control (without foliar nutrition with marine calcite). Additionally, in the years 2011-2012, an identical experiment was carried out with another sugar beet cultivar. For each combination, the gross production value, foliar nutrition costs, the net production value and profitability index were calculated. The total cost of application of foliar calcite was 190 and 240 PLN/ha. The gross production value of sugar beet in experiment 1, on average over three years of research, increased in combination 1 by 24.8% and in combination 2 by 25.6% compared to the control; in experiment 2, on average for 2 years of research, in combination 1 by 15.7%, and in combination 2 by 15.0%. The increase in the net production value in experiment 1 amounted to 22.8 and 23.2% respectively, and in experiment 2 - 13.9 and 12.8%. The indicator of the profitability of foliar nutrition with marine calcite in experiment 1, on average, for the period 2010-2012, amounted to 12.6 in combination 1 and 10.3 in combination 2. In experiment 2, the index of profitability of foliar nutrition, on average, for the period 2011-2012, reached the value of 8.96 for object 1 and 6.77 for object 2.

The aim of the paper was to analyse the relation of milk yield per cow with a set of production factors on sample data from six dairy farms located in the central region of Poland. The farms, which were the subject of the study, carried out an intensive production, achieving milk yield over the national average. The research showed an increase in milk yield with increasing number of cows in the herd, which, in practice, can lead to increased loads in milking installations in farms keeping more cows.
