AbstractThe purpose of this study was to estimate the expected effects of sprinkler irrigation, applied depending on the rainfall amounts, on the yield increasing of marketable carrot roots (Daucus carota L.). The experiment was performed on light soil in different regions of Poland at the critical period considered from May 1st to July 31st. A straight line relationship between the yield increase and the use of sprinkler irrigation depending on the amount of precipitation was adapted. The carrot roots yield was determined for five agroclimatic regions of Poland. The amount of rainfall in the average dry years (P50 %), medium dry years (P25 %) and very dry years (P10 %) was defined by the Ostromecki method. The largest precipitation deficit in the cultivation of carrot during the critical period in the average dry years and medium dry years was found in the C-N-W region of Poland. In the very dry years the largest rainfall deficit was in the C-E region of Poland. The smallest precipitation deficiency was noted in the S-E region of Poland. The highest increase of the roots yield, observed as the influence of sprinkler irrigation applied during the average dry years and medium dry years, is expected in the C-N-W region of Poland. In the very dry years the largest raise of the roots yield can be expected in the C-E region of Poland. The predictable production effects of sprinkler irrigation, estimated in the present study, show a great possibility of increasing of carrot roots marketable yield in field cultivation under optimum water conditions.
