Abstract: 
Evening Primrose (Oenothera biennis) is the herbaceous plant; biennial fuchsia belongs to the family Onagraceae. The yellow flowers of this plant are bisexual. The seeds contain non saturated oils as γ-linolenic acid, Linolenic acid and Oleic acid. In this research toping height (without toping and toping on 20, 30, 50 cm of plant) and irrigation type (drip, furrow) treatments on length and width of leaf, node distance, number and length of flowering stems per plant; and in complete ripening the characters of weight of seed per capsule and per plant, weight of 1000 seed, number of capsule per stem and per plant, weight of fresh/ dry shoot material and oil extracted from seeds were measured. The results showed that by increasing of toping, width of leaf, internode distance, length of lateral stems were decreased. In drip irrigation internode distance, length and number of lateral stem increased. The most of number capsule per stem and plant, weight of seed per plant, weight of 1000 seed, oil percentage of seed were obtained in toping of 30cm and drip irrigation. This research is primary investigation about toping height and irrigation type in Primrose and more studies for complete results are necessary.
