abstract:
In the work the influence of three methods of husbandry (tillage cultivation, no tillage cultivation, direct sowing), as well as weather conditions (temperature, precipitations) on spring barley yielding for was estimated for the period 1994-1999. Temperature in the period of sowing-emergence oscillated from 7.9 to 11.7oC. In subsequent periods the values of temperature increased systematically. The most diverse (from 0 to 112.5 mm) and variable (145%) precipitations appeared about the period from milk stage to dough stage. The highest yields for the whole investigative period were noted on the object with traditional cultivation (32.1 dt h-1). No tillage cultivation and direct sowing caused significant degradation. The best barley yielding was found in 1996 and 1997 on the object with traditional tillage. The worst yielding appeared in summers of 1994 and 1999, when 26.0 and 13.5 dt h-1 was obtained, while the mean for the whole investigative period was 28.7 dt h-1.
