This research was carried out in experimental field of
Southeastern Anatolia Agricultural Research Institute in
randomized split bloc design with three replications for
three years (2004 - 2005, 2005 - 2006 and 2006 - 2007
growing seasons). The objective of this study was to
determine the effects of seeding rates on grain yield and
yield components of two durum wheat cultivars (Aydin-93 and
Firat-93) under permanent bed planting in cotton–wheat
cropping system. Six seeding rates (50, 150, 250, 350, 450
and 550 seed per m-2) were tested. Seeding rate
affected grain yield and yield components except for protein
content, but its effects is being altered from year to year.
The results revealed that 253 seed per m-2 (111
kg ha-1) proved as predicted optimum seed rate;
producing highest grain yield (5162 kg ha-1) as
regards averages of all years. Among varieties, significant
differences were found for yield and yield parameters.
Key words:
Chlorophyll content, durum wheat, grain yield, grain
quality, seeding rate, permanent bed planting.
