    Jerusalem artichoke is one of such plants that can be put to energy use. The objective of the research study was to assess the impact of fertilization with sewage sludge and conifer sourced ash biomass on yields as well as biometric and physiological parameters of two cultivars (Albik and Gigant) of Jerusalem artichoke (Helianthus tuberosus L.). The two-year study was carried out in fields located in Ujkowice near Przemyśl. The trials covered 3 factors, as follows: 4 levels of fertilization with biomass – ash from conifers, 2 levels of fertilization with sewage sludge, 2 cultivars of Jerusalem artichoke (Helianthus tuberosus L.) – Gigant and Albik. In the first year after the application of sewage sludge in an amount of 30.3 t ∙ ha–1, the yield was lower by about 0.8 t and in the second, the reaction to fertilization using sludge was positive. Differences in yield under varied levels of fertilization with sewage sludge depended on the length of shoots as well as the LAI and SPAD indicators. Biomass ash fertilization resulted in systematic increase in yields of the vegetative (aerial) parts in 2013. In the subsequent year, differences were insignificant. Yield increase in Jerusalem artichoke fertilized with biomass ash was associated with increased lengths of shoots, increasing values of the LAI and SPAD. There was no significant interaction between the organic and mineral fertilization. Amongst the two tested, Albik cv. was characterized by higher yields. The Polish Albik cv. was characterized by higher shoot lengths, smaller shoot diameters, higher LAI index, and a much higher SPAD (cultivar related features) value, while the Fv/Fm index for both cultivars was similar.

    The influence of farming systems on the technological quality of grain and flour cultivars of winter wheat

    The research material were cultivars of winter wheat grain from field experiments conducted in 2009–2010 from the National Research Center of Mecklenburg and Western Pomerania (LFA) in Gulzow. The first factor was a system of farming (conventional, ecological) and the second factor was the cultivars of winter wheat (Akteur, Adler, Discus i Hermann). Determined physical properties of grain, quality properties and rheological properties determined on farinograph. The use of conventional and organic cultivation system had no significant effect on the physical properties of wheat grain. Winter wheat grain obtained from conventional cultivation system characterized by a better quality than a grain from ecological system. Significantly higher values were obtained for crude protein content, gluten content, gluten softness and rate of sedimentation except for the falling number and index gluten. Using the conventional system obtained a better farinograph properties compared to the ecological. The exception was the waterabsorpsion for which there wasn’t significant differences. The best quality of grain and flour characterized by a cultivar Akteur and Adler but the worst cultivar Hermann.

    Rating long-term use of simplifications in tillage and previous crop on biometric features, physiological and yield of winter wheat cultivar ‘Kobra Plus’

    The study was conducted in the years 2006–2008, in a static experiment founded in 1993 in the Agricultural Experimental Station Lipnik (near Stargard Szczeciński). The station is located in the central part of the Szczecin Lowland (ϕ53021`N, 14058`E, Hs 30 m.a.s.l.). Field tests were carried out using winter wheat grown in four-field crop rotation (sugar beet – winter wheat – faba beans – winter wheat + white mustard intercrop). The effect of simplified tillage involving the elimination of plowing for the plowless tillage and direct sowing was examined, as compared to conventional tillage under crops grown in rotation. Studied factor consisted of the farming systems used for winter wheat after different forecrops (faba beans, sugar beet). The tillage systems significantly shaped the length of the stalk and leaf assimilation index (LAI). Winter wheat grown in the field after faba bean had significantly higher values of total number of steam and, with ears, the length of stalk and spike, as well as the ratio of leaf greenness (SPAD). In our study, there was no the effect of experimental factors and their interaction on grain yield of winter wheat. Regardless of tested experimental factors, winter wheat yielded at the level of 5 t ∙ ha–1. A slight tendency to higher yields was recorded for the traditional plowing system.
