abstract:
A field experiment with parsley cultivated after direct sowing was conducted in the years 1997-2000. The effect of no-tillage and cover crop mulches (white mustard, spring vetch, tansy phacelia, and oat) on the geometrical features of parsley roots was investigated. The application of mulches had no significant influence on the roots geometrical features, i.e. length, diameter, coefficient of slenderness. The shape of parsley roots was modified by the method of the tillage prior to sowing. Parsley roots after application of spring ploughing were significantly longer and fatter than after direct sowing. In all study years, the coefficient of roots slenderness after direct sowing was higher than after spring ploughing. On the traditionally cultivated objects, parsley roots were fatter comparing to those grown under zero tillage. The roots from the ploughed objects had a more conical shape than those of the zero tillage. The roots from the no-tillage objects were shorter but more slender, and their shape was more cylindrical.
