The aim of the study was to evaluate the nutritional status of 16-18-year-old youth, from the Kuiavia-Pomerania region, on the basis of somatic parameters. The research included 155 girls and 137 boys, attending second and third classes of secondary schools with vocational or general education profile. The nutritional status evaluation was made on the basis of measurements of: body mass and height, skinfolds thickness, arm, waist and hips circumference and the calculated indices: BMI and AMC. The results obtained were interpreted individually with reference to somatic development indices worked out for Warsaw adolescents by Palczewska and Niedźwiecka [2001]. The mean values of somatic parameters obtained in the study for the youth of the Kuiavia-Pomerania indicate proper body sizes, i.e. body height and mass according to age and mass-to-height ratio. Moreover excessive adiposity and too low muscle mass of the studied youth were stated. Such disproportions in body composition were also revealed for youth with undernutrition and overweight. The results obtained suggest the occurrence of irregularities in eating habits and/or improper way of life of the youth, including low physical activity.
The study was carried out in order to determine the frequency of droughts in the period of increased water needs in potato, and to assess the needs and expected productive effects of the plants grown under irrigation on the basis of temporal variation of the standardized precipitation index SPI in the Kujawsko- Pomorskie district. Rainfall data were derived from standard measurements of atmospheric precipitation in between 1 July and 31 August in the multi-annual period 1981-2010.These data were obtained from the branches of COBORU in Chrząstowo, Głębokie and Głodowo, and the University of Technology and Life Sciences Research Centre in Mochełek. The results of carried research showed that the frequency of occurrence of dry spell during the period of increased needs for water of potato amounted to 26.7-40.0% in the region, depending on the locality. Strong droughts occurred in the year 1983, 1989, 1992 and 1994, moderate drought in 2005 and weak droughts in 1982, 1984 and 1999. Great irrigation needs of potato which corresponded to periods of strong and moderate droughts (SPI ≤ - 1.0) have been identified in 5 years of the 30 years examined. The expected increase in the yield of potato tubers grown on light soils under irrigation during those years exceeded 15.7t.ha-1. In the 9 years of the 30 have occurred mediumlevel irrigation needs, which in the period of July-August, corresponded to SPI values between 0 and -1.0.
Common juniper (Juniperus communis L.) is the well-known and valuable medicinal plant. Juniper berry is used as a herbal medicine mainly due to its essential oil with diuretic, antiinflammatory, choleretic and cholagogue activities. Some other substances, as polyphenols, are present in juniper berries and other parts of this plant. The aim of this study was to estimate total polyphenols content in common juniper sprouts (leaves) originating from different places at the kujawsko-pomorskie province. The total polyphenols content was carried out by means of spectroscopic method with Folin-Ciocalteu reagent and shown as pyrogallol equivalents. The obtained results ranged in limits from 2.40±0.23% to 3.43±0.17%.
The aim of the study was the analysis of the condition of goat breeding and husbandry in the Kujawy-Pomerania Province and in country. The results concerning milk and reproduction performance of goats from this region can be used for working out a regional breeding programme. The following was taken into account in this study: the number ofWhite and Coloured Improved goats covered by the performance recording, number of goats entered in the flockbooks, milk performance results for the Kujawy-Pomerania Province as well as for Poland for the years 1996–2009, using the information published by the Central Animal Breeding Station and the documentation of the RegionalAssociation of Sheep and Goats Breeders in Bydgoszcz. The number of flocks of White Improved goats covered by the performance recording in our country decreased from 170 in 1996 to 0 in 2009. A similar downward tendency was observed for the number of goats under milk recording. In the Kujawy-Pomerania Province, the number of goats under milk recording increased from 45 in 1996 to 289 in 2007, and fell to zero from 2008. Analysing the population of Coloured Improved goats, it turned out that, on average, in the whole country, the number of flocks of this breed increased from 17 in 1997 to 23 in 2004, and then decreased to 1 flock in 2009. Similarly, the number of goats under milk recording increased from 175 in 1997 to 917 in 2004 and then fell to 22 in 2009. In the analysed period, the extension of lactations, increased yields of milk, fat and protein and similar contents of these components in milk were found inWhite and Coloured Improved goats.
The survey of 5 Kujawsko-Pomorskie villages carried out in 2001 in Poland shows that in rural communities there are hierarchical formal and informal structures and the inhabitants are able to separate and indicate their leaders. Most of the informal opinion leaders also perform some formal duties. Farmers who are considered to be leaders of the local community own farms with more potential than other persons, they are better educated than others, they do not differ in respect of age from their imitators although the position of a leader is most frequently occupied by people aged more than 50 than 30-40. The examined leaders have successors which may motivate them even more to maintain their farms at a good level. Leaders compared with other farmers value more outside sources of information, and they feel more need to introduce changes, they are also more interested in getting familiar with novelties. Leaders of the examined populations more often than the other farmers declared a need to intensify cooperation with advisors. The research proved that TV is a very important source of information for all the people regardless their social status. The lower the education level is the more valued television is as a source of information. Advisors are more appreciated by better educated respondents. The higher education of the farmers the more they appreciate advisors as information sources and the more willing they are to introduce innovations to they farms.
