Roseroot (Rhodiola rosea L.) is an important medicinal plant with welldocumented adaptogenic activity. The decrease in its natural resources induces to undertake research on the introduction of this species into cultivation. The aim of the present work was to determine the effect of organic and mineral fertilization on increasing the biomass of underground parts of Rh. rosea and the level of biologically active compounds. Throughout the study period, the highest raw material yield was obtained after the application of the following doses of mineral fertilization: N – 60.0 kg·ha-1, P – 35.2 kg·ha-1, K – 83.0 kg·ha-1, without manure. The use of manure caused a decrease in the average rhizome and root weight by more than 20%. Mineral fertilization application increased the average raw material yield by about 30–40% and allowed obtaining the highest weight of underground organs of the species in question already in the fourth year of cultivation. Furthermore, the present study demonstrates that mineral fertilization does not affect substantially the level of the individual groups of compounds in the raw material, but the use of manure may significantly reduce the content of phenylpropanoids. The level of active compounds is also influenced by crop age. Two-year-old plants were characterized by the highest content of phenylpropanoids as well as by the lowest content of phenylethanoids and phenolic acids. In the following years of cultivation, no statistically significant changes were observed in the level of the analysed groups of compounds.

This manuscript presents results of authors` research regarding selected factors influencing sensory pork quality. In the manuscript the role of breed, genes (RYR1T, RN-, CAST), slaughter weight as well as meatiness is comprised. Additionally, the role of intramuscular fat, ultimate pH and heat treatment on pork quality is discussed. It was stated that the optimization of the sensory aspects of the pork quality should not be limited to one aspect only but it should include the practical use of a number of dependent determinants. Obtaining high eating quality depends also on the quality of the raw material and the way of thermal processes (temperature, time, method of thermal process).

Herbs, in spite of their relatively small acreage, play an important role in Polish economy. Their significance relies on wide employment, especially in pharmacy, food industry and cosmetology. They are essential for international trade, too. Herbs cultivation differs from other crops due to the importance of raw material quality in their usefulness. Among fac­tors affecting raw material productivity and quality, effect of watering is little recognized. In general, water accessibility ensures higher biomass production, but at the same time causes decrease of biological active components content. However, in some cases, devia­tions from this principle have been found.
