Abstract
The field experiment was carried out on the Scientific-Experimental and Introductory Facility of the Department of Plant Growing at the AU – Plovdiv in the period 2008 – 2011. The experiment was performed by means of a block method with four replications; experimental field area – 15 m2. The effect of two sowing timings (October-November and January- February) and five sowing rates (150, 200, 250, 300 and 350 g.s/m2) on the yield and yield components of the Sandra variety coriander were determined. The analysis of the results showed that the two experimental factors (sowing time and sowing rate) in combination with the meteorological conditions during the years of the study had a significant influence on the yield and yield components of the Sandra variety coriander. The maximum values of the yield components of coriander (number of umbel per plant, seed weight and 1 000 seeds’ weight) were recorded for the October-November sowing applying sowing rate of 300 g.s/m2 when compared with other tested variants. During the period of study (2008–2011) the highest seed yield of 2 142 kg/ha was obtained from the October – November sowing and sowing rate of 300 g.s/m2 and the lowest one – of 1296 kg/ha from the January-February at a sowing rate of 150 g.s/m2. The most suitable sowing time for the Sandra variety coriander is October–November and the most effective sowing rate of 300 g.s/m2 for the region of Plovdiv.
