The increasing demand for the production of cereals, both in Poland and in the world, puts farmers face a major challenge due to the constantly changing climatic and soil conditions. A sustainable policy of managing natural resources limits or excludes use of plant protection products and pesticides. Cultivation of cereal varieties with high resistance to pests as well as climate and soil changes constitute a new challenge for plant production. The article presents the results of field research on Winter Barley cultivation – Kanagoo and cultivars Conchita taking into account the changing soil and climatic conditions. From the obtained research, it can be concluded that the results achieved by the Kangoo variety could have been influenced by the application of two-treatment protection and the earlier sowing date.The lower protein content of the Conchita variety, despite the use of a higher dose of nitrogen, is a species characteristic of this variety.

Rosnący popyt na produkcję zbóż, zarówno w Polsce, jak i na świecie, stawia przed rolnikami duże wyzwanie ze względu na stale zmieniające się warunki klimatyczne i glebowe. Zrównoważona polityka zarządzania zasobami naturalnymi ogranicza lub wyklucza stosowanie środków ochrony roślin i pestycydów. Uprawa odmian zbóż o wysokiej odporności na szkodniki oraz zmiany klimatyczne i glebowe stanowią nowe wyzwanie dla produkcji roślinnej. W artykule przedstawiono wyniki badań polowych uprawy jęczmienia ozimego – Kanagoo i odmian Conchita z uwzględnieniem zmieniających się warunków glebowych i klimatycznych. Z przeprowadzonych badań można wnioskować, że na wyniki uzyskane w przypadku odmiany Kangoo mogło mieć wpływ zastosowanie ochrony dwuzabiegowej oraz wcześniejszy termin siewu. Niższa zawartość białka odmiany Conchita, pomimo zastosowania wyższej dawka azotu, wskazuje na to, że jest to cecha charakterystyczna dla tej odmiany.

Garum or Grain? Crimea and the Provisioning of Constantinople (7th to 9th centuries)

Historians have relied for too long on written sources (the letters that Pope Martin I wrote from Cherson, as well as De Administrando Imperio) to assess the economic situation in the Crimea, especially in Cherson, during the so-called Dark Ages (7th to 9th centuries). Many still believe that that city could not have survived without shipments of grain from the outside, particularly from the lands along the southern coast of the Black Sea. Seals of Byzantine officials found in Cherson tell a different story, as they indicate commercial exchanges between the Crimea and Constantinople. If the peninsula participated in trade, something must have been offered in exchange for the goods coming from the Capital. The archaeological evidence strongly suggests that during the 8th and 9th centuries, the hinterland of Cherson, as well as the Kerch Peninsula (eastern Crimea) witnessed rapid economic development, largely based on the cultivation of crops. Silos found on several settlement sites, both open and fortified, suggest a surplus, which was most likely commercialized. If so, the closest markets were across the Black Sea, to the south, primarily in Constantinople. Other commodities, such as wine transported in amphorae, traveled in the opposite direction, across the Sea of Azov and into the interior of Khazaria. In exchange, the peninsula received shipments of grain, which were then re-exported to Constantinople. Far from relying on shipments of grain from the Capital, Cherson and the rest of the Crimean Peninsula in fact supplied Constantinople with food. Numerous vats for the production of fish sauce have been found in Cherson, and many were in operation before 900. A good deal of the garum served at tables in Constantinople between the 7th and the 9th century must have come from Cherson. The archaeological evidence therefore calls for a re-assessment of the economic situation in the Crimean Peninsula during the “Dark Ages”.
