The study reports the effects of four sowing densities (40 x 10, 40 x 20, 60 x 10 and 60 x 20 cm) on the agronomic characteristics of Isatis tinctoria and I. constricta under the rainfed conditions of South Eastern Anatolia. Wide row spacings of 60 x 10 or 60 x 20 cm were effective in obtaining maximum number of leaves per plant, leaf length, leaf width, petiole length, stem diameter, fruit length, 1000 fruit weight and 1000-seed weight. However, narrow row spacing (40 x 10 or 40 x 20 cm) led to maximum values of fresh and dry leaf yield 10 m -2, plant height, fruit yield and fruit length, minimum hull content, and the highest indican percentage and indican yield m-2. This information will be helpful for the economical cultivation of these plants under the rainfed conditions of South Eastern Anatolia. ©2007 Akadémiai Kiadó.
