|
In order to investigate the effect of sowing date on yield and yield components of hemp, this study was conducted
in the field condition during 2012 in a randomized complete block design with three replications and three
sowing date consist of 30 April, 10 May and 20 May as treatments in research station of faculty of agriculture of
Azarbaijan Shahid Madani University. Results showed that maximum plant height, biological yield of plant, seed
number per plant, weight of seeds per plant, yield of seed per hectare was obtained from the second sowing date
and maximum value of harvest index belonged to first date. Maximum 1000 seeds weight and seed oil yield per
plant was observed in the first planting date but there was no significant difference with the second planting date.
Finally, it seems that middle of May is the best time for hemp planting at western agronomic lands of Iran.
