Abstract: Stubble sowing by pointed, single disc and double disc coulters with straw purifier and without them was investigated in this article. The influence of straw gathering and soil preparation for sowing upon soil hardness during sowing and plant vegetation period was investigated. After sowing the amount of straws in notches, amouint of sprouts, and yield were established. Straws chopped and spread on soil surface, under dry weather conditions, reduces loam soil hardness in sowing depth from 1400 kPa to 600-700 kPa. When the soil is wet, the influence of straws upon soil hardness is insignificant. During plant vegetation period, soil hardness in all sawing versions increaased, when soil moisture content was constant. Soil hardness influences insertion of straws in to sowing notch by coulters, though influence is different using pointed and disc sowing coulters. Straw purifiers in front of sowing coulters reduces the amount of straw inserted in sowing notch from 2.3 to 6.2 times
