STUDY ON EFFECTS OF HEAT AND DRUGHT OF SEASON END ON
SOME AGRONOMIC TRAITS OF SIXTEEN CANOLA VARIETIES IN
WEST SOUTH IRAN
AbstraCT
In this study the effects of heat and drought at season end on some agronomic
traits in sixteen canola varieties were carried out in Behbahan Agricult Research
Station in west South Iran . The statistical analysis were carried out according to
completely randomized blocks base on creating four environments of plant growth
by different planting date and cutting the last irrigation of plant growth. Created
four environments were planting dates at: November1-20 (normal), Novembeber
2-20 with cutting last irrigation (tension ), December 3-20 (heat tension) and
December 4-20 with cutting last irrigation (drought and heat tensions). Three
replicationions were used in this experiment. Results showed that heat and
drought tensions presented significant differents (p  1%) between four
environments for number pod per plant, number seed per pod and seed thousand
weight. Hyola variety had the highest yield, therefore this variety was
recommended for all same areas.
