Phenological phases and their possible influence on soil erosion at maize

Original language description

The contribution consists of two parts. The first part deals with evaluation of data from phenological observations of the Czech Hydrometeorological Institute (CHMI). The calculation of the value of protective effect of vegetation (C factor) for years with long and short growing season was carried out in the second part. The paper deals with the onsets of phenological phases (emergence, heading and milky wax ripeness) and agrotechnical operations (sowing and harvest) of maize. Detailed analysis for particular years was carried out for Strážnice station (1991-2012). Analysis of average values shows that the longest growing season (152 days) was in the period 1991-2012. When this data was compared with the period 1931-1960, the prolongation of growing season was proved (by 6 days). Analysis of the average values shows that prolongation of interval between phenological phases of emergence and heading was proved (from 38 days to 62 days). On the average the sowing was carried out at the earliest in the period 1931-1960. And the harvest was carried out at the latest in the period 1991-2012. The analyzed data show a great variability in the onset of phenological phases and in implementation of agrotechnical operations. First of all the meteorological conditions are going to have significant influence on the progress of maize and the onset of phenological phases. The value of the protective effect of vegetation shows how certain crop protects the surface of soil from falling drops of rain. Higher values of C factor were detected in each year with short growing season. The percentage difference between years with a long or short growing season is 10% for 1968 and 1986 and 35% for 1994 and 2010.
