In order
to investigate the impacts of sowing date and row spacing on
yield and yield components of Hashem chickpea
variety, a
field experiment was conducted in 2005 at farm of Dorood
Faraman (Kermanshah-Iran). In this study, the sowing date in
three level (6, 23 November and 6 December) and the row
spacing in three level on rows (20, 30 and 40 cm) were
evaluated with complete randomized block design in factorial
arrangement. Results of experiment showed that there are
significant differences for planting date and planting
density effects of plant height, number of branch per plant,
distance between 1st pod to soil, number of pod
per plant, number of grain per plant, biological yield and
grain yield. The maximum grain yield belongs to sowing date
6 November and row spacing 30 cm. However maximum number of
pod per plant and grain per plant belong to 40 cm row
spacing but higher number of pod and grain per unit area in
20 cm row spacing results in increasing grain yield in this
row spacing. Results show increasing planting density
resulted in decreased yield components, but on the other
hand increased plant number compensated for decrease of
yield components. Also we found that planting at 6th
December had higher distance of pod from soil surface and
thus easier for mechanized harvesting.
Key
words:
Chickpea, sowing date, row spacing, grain yield, yield
components. |
