The text discusses the factors affecting the prices of wheat, barley, corn, sunflower, and soybeans in the global and Russian markets. For wheat, factors leading to price growth include increased demand for Russian wheat and barley and decreased supplies from Ukraine. Factors leading to price decrease include high wheat harvest rates in the US and the successful passage of the first Ukrainian trading ship from Odessa to Turkey without grain agreements. For barley, factors leading to price growth include active demand from Saudi Arabia, Jordan, and North African countries. The sunflower market has seen a growth in prices due to significant demand from Egypt, India, and possibly China, while the factors leading to price decrease include a potential decrease in export duties and reduced buying activity before the new season. There are no significant factors affecting the prices of corn, and soybean prices have been influenced by high demand from China and improved soybean crop conditions in the US.
