Evaluation of the onset of phenological phases of spring barley

Popis výsledku v původním jazyce

Detailed analysis of the phenological data of the Czech Hydrometeorological Institute was made in this paper. The analysis was carried out for spring barley (Hordeum vulgare) for Poděbrady station (177 m a.s.l.). These phenological phases were analyzed: emergence, tillering, the beginning of leaf sheath elongation, first node, second node, swelling of the sheath of the last leaf, heading, milky ripeness, yellow ripeness and full ripeness and these agrotechnical operations: sowing and harvest. It was found out that growing season has been prolonged by average of 9 days. Harvest was on average delayed by 11 days in the period 1991-2010 (according to the period 1931-1960). Analyzed data show great variability in onset of phenological phases and implementation of agrotechnical operations. The weather has significant influence on development of spring barley and onset of individual phenological phase in given year. Greatest variability in onset of phenological phases was detected at tillering. This phenophase occurs from the 96th day to the 139th day of the year (range of phenophases is 43 days). The greatest variability of all data was found out in agrotechnical operation sowing. Difference between analysed years is up to 58 days. Sowing of spring barley usually is going on from the 56th day of the year to the 114th day of the year.
