| Popis: | Impact of 10 factors related to the environment, crop management and organisation on yields of commercially grown winter wheat was investigated at Błonie-Topola experiment farm over the years 1980-2007. From among the factors under investigation, yields of winter wheat were negatively affected by delayed seeding and excessively high seeding rates. Trends of grain yields, value of the preceding crops, NPK fertilization, percent of cereals in total cropland, labour consumption of crop production were also investigated. Due to changes in farming conditions (discontinuing of livestock production, employment reduction, increase of cereals in total cropland) there was a tendency for the seedbed value to deteriorate and for potassium and phosphorus fertilization level to decrease. However, due to increased nitrogen rates and correctly applied other elements of crop management it was possible to obtain satisfactory yields of winter wheat. |
