DELIBALTOVA, V., Hr. KIRCHEV, I. ZHELIAZKOV and I. YANCHEV, 2012. Influence of predecessor and sowing rate on seed yield and yield components of coriander (Coriandrum sativum L.) in Southeast Bulgaria. Bulg. J. Agric. Sci., 18: 315-319
A field trial was carried out during 2007-2010 in Southeast Bulgaria for estimation the influence of different predecessors (sunflower, stubble, coriander and sorghum) and the sowing rate (200, 250, 300 and 350 g.s/m2) on the elements of productivity and seed yield of coriander. The results of some analysis showed that maximum number of umbel per plant, number of seeds per umbel, number of seeds per plant and weight seeds per plant was recorded after stubble predecessor and sowing rate of 300 g.s/m2 when compared with other tested variants. The most suitable predecessor for the coriander is stubble and yield obtained surpassed those after predecessor sunflower, coriander and sorghum by 37, 21 and 50% respectively. The most effective sowing rate is 300 g.s/m2 under the South-East Bulgaria conditions.
