Evaluation of morphological traits, yield and yield components of Datura (Daturea stramonium. L) as affected by different planting time in Ardabil region
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 2
Abstract
The aim of determining optimumplantingdate is to designate aperiod of time that environmental factors for germination, emergence, establishment and seedling surviving is suitable in this period. Accordingly an experiment was conducted in 2011 growing season to evaluating the effect of different planting date of morphological traits, yield and yield component of datura in experimental field of Azad University of Ardabil in randomized complete block design (RCBD). Experimental factor was: first planting date (21 Apr), second planting date (5 May) and third planting date (20 May). Results showed that planting date affect leaf number and area, pod total weight, seed weight in pod, seed number, one seed weight, seed yield and leave chlorophylls significantly. In all studied traits maximum amounts was in first planting date and third planting date had the lowest value of experimented traits. The highest yield of seed production reached in first planting time with average of 38.38 gr per each bush. With late planting significant decrease in yield production were seen. Choosing the best planting time is an affective factor on growth process, morphological traits, yield and yield component as changing these characteristics with planting date, final products was impressed consequently.
