Transpiration ? an Important Contribution to Overall Water Balance of the Hop Plantation

Popis výsledku v původním jazyce

Transpiration of the Czech hop Premiant (Humulus lupulus L.) plantation was investigated during three consecutive growing seasons and compared with Penman-Monteith based reference evapotranspiration and transpiration estimated by FAO dual crop approach.We measured the sap flow of the twelve individual bines (using the stem heat balance sensors type EMS SF 62). Actual bine transpiration peaked in August, when the crop was fully developed, at less than 3 mm day-1, which was 60% of the reference evapotranspiration and only 65% of the transpiration estimated by dual crop approach. Seasonally, most of the water was potentially evaporated from the soil surface and transpired by the understory vegetation (i.e. weeds). Less than half of the total amount of vaporized water was transpired (the partitioning depended on a stage of crop development), which makes space for the water-saving techniques in hop growing.
