The field experiments (1996-98) were carried out on sandy-loam and silty soils. From among row distance compared, plants grown in single rows (30 and 40 cm), on both soils were higher in comparison to those in double rows (40-20-20 cm) and triple rows (40-20-20-20 cm), but produced lesser number of branches. In result, the yield of herb was significantly higher from objects, where band arrangement of rows were applied (on average by 25 percent on sandy-loam soil and by 23 percent on silty one)
