Abstract:
In order to study the effect of planting depth and summer
temperature control on growth and yield of saffron (Crocus sativus
L.), an experiment was conducted at Agricultural Research Station
in Zabol University (Iran) during 2004-2005 growing seasons. The experiment
was laid out in a split plot within a Randomized Complete Block Design
(RCBD) with four replications. The main plots consisted of three planting
depths (10, 15 and 20 cm) and three different methods for summer temperature
control (check, mulching and irrigation) were arranged in subplots. The
results revealed that by increasing the planting depth, corm propagation,
contractile roots number, flowering time, leafing time and leaf number
were decreased significantly, but leaf length and stigma were increased.
Flowers number and corm weight were increased significantly by increasing
planting depths from 10-15 cm, but both of them were decreased in 20 cm
depth. In response to summer temperatures control treatments, flowering,
leafing, leaf and stigma lengths were increased but corm propagation decreased
significantly, due to decreasing temperature treatments. Leaves and contractile
roots number were not affected by summer treatments. In response to temperature
control and planting depth interaction, the most corm propagation and
leaf number ware obtained at 10 cm planting depth and control treatments,
also minimum corm propagation and leave number was obtained at 20 cm planting
depth with mulching treatments. Minimum flower number was obtained at
10 cm planting depth with irrigation and its maximum number was obtained
at 15 cm planting depth with mulching.
