The Effects of Different Planting Densıtıes on Yield And Some Yield Components of Eremurus Spectabilis (BİEB.)
Eremurus spectabilis (Bieb.) is a member of the Liliceae family. The plant is perennial and reach a height of about 0,7 to 1,5 m. It grows 1000-2700 m above sea level; stony slopes, limestone rocks and steppes. Young leaves and shoots are consumed as vegetable.
The research carried out in the years between 2008-2010 in Erzincan Horticultural Research Institute in order to determine the effects of different plant densities on yield and yield components of Eremurus spectabilis. Plants have been planted as the nine different planting densities (25x10, 25x15, 25x20, 30x10, 30x15, 30x20, 35x10, 35x15, 35x20 cm). In experiments, the first emergence time, emergence period, date of harvest, mean shoot height, width, weight, diameter, leaf number, yield (kg/m2), total dry matter, total soluble solid content, pH, acidity, vitamin C have been examined.
E. spectabilis is a early spring vegetable. It can be harvested in the second week or third week of April accordin g to years. The highest yield (1.32 kg/m2 ) have been obtained from 25x10 cm planting density. This was followed by 1,18 kg/m2 yield with 25x15 cm planting density. The yield components were affected positively from 25x15 cm planting densitiy than 25x10 cm planting densitiy. As a result, 25 x10 cm and 25 x 15cm planting densities have been determined as the most appropriate planting densities.
