“…Indeed, it was unexpected and the most striking result of this study. In safflower there is a general agreement that seed yield is increased by irrigation (Ibrahim et al 1991). However, the results of some research seem to support our finding that there has been no marked response to irrigation in safflower.…”

Producers in highland and semiarid regions have difficulty in increasing diversity in crop rotations due to unfavorable conditions imposed by cool temperatures, inadequate rainfall, and shorter growing periods. In such conditions, safflower appears as a promising alternative because it is cold and drought tolerant. The objective of this study was to determine the responses of the hybrid and open-pollinated safflower genotypes to irrigated and non-irrigated conditions in a highland environment. For this reason, the field research was performed during the years of 2001 and 2002 in eastern Anatolia, Turkey. According to the results of the study, safflower genotypes tested were well adapted to the cool and short-season conditions in this region. The response of seed yield to genotype varied depending on the growing seasons. The non-irrigated plants produced nearly the same seed yield as irrigated ones. Average seed yields of safflower genotypes tested were 914.3 and 928.0 kg/ha in 2001, and 1143.6 and 1139.9 kg/ha in 2002 years for irrigated and non-irrigated experiments, respectively. In general, the genotypes differed in all of the investigated traits. In both irrigated and non-irrigated experiments genotype × year interactions were very significant for all parameters. This research shows that in semiarid and highland environments safflower has a big potential value as an oilseed crop under dryland conditions.

“…These findings could be attributed to the highly significant differences among seed yield due to irrigation treatments, as well as differences between water consumptive uses. These results are in line with those reported by Ibrahim et al (2008) who showed that the best water use efficiency (WUE) for seed production was obtained from irrigated safflower plants at 60 % of ASMD.…”

“…This increase for seasonal water consumptive use at 45% of ASMD may be to higher water around root zone provides chance for more consumption of water that ultimately resulted in increasing transpiration by plants and evaporation from the soil surface. These results were in harmony with Katara and Bansal (1995) and Ibrahim et al (2008) who mentioned that water consumptive use by safflower plants increased as the available soil moisture around the root zone increased.…”

“…Also, they added that seasonal water consumptive use increased with an increase in number of irrigations from 1 to 3 (145.5 to 236.0 mm), whereas water use efficiencies declined considerably from 14.2 to 11.0 kg seeds /ha /mm.

This study was conducted on the Experimental Farm of the Shandaweel Research Station at Sohage, Egypt, during 2006/07 and 2007/08 growing seasons. The investigation was aimed to study the effect of irrigation at 45, 60 and 75% of available soil water deficit (ASMD) and two plant population densities (35000 and 70000 plants/ fad.) on productivity and water use efficiency of some genotypes (Lines 1, 2, 3 and Giza1 cv) of safflower. A randomized complete block, split-split plot design with three replicates was used in each season. Irrigation treatments, genotypes and plant population densities were randomly assigned to the main, sub-plots and subsub plots, respectively. Results showed that irrigation at 45% of ASMD significantly increased plant height, number of branches /plant, number of heads /plant, 100-seed weight, weight of seeds /plant, seed yield /fad., seed oil content and oil yield /fad. by 35.0, 45.8, 50.6 13.9, 49.9, 34.0, 7.3 and 43.8%, respectively, compared to irrigation at 75% of ASMD. Increasing plant population densities from 35000 to 70000 plants /fad. significantly increased plant height, seed and oil yield fad-1 , while, decreased number of branches /plant, number of heads /plant, 100-seed weight, weight of seeds /plant. In this case, seed oil content was not affected by plant population density. In general, Line 3 surpassed others genotypes in the most studied characteristics. The interaction between irrigation regime x genotype as well as irrigation regime x plant population density had a significant effect on the 100-seed weight, seed weight /plant, seed yield /fad., seed oil content, oil yield /fad and WUE. Meanwhile, interaction between plant population density x genotype or between three factors, had a significant effect on seed yield /fad. and WUE only. Seasonal water consumptive use was 30.03, 26.05 and 23.95 cm when irrigated safflower plants at 45%, 60% and 75% of ASMD, respectively. Results indicated that irrigation at 60% of ASMD gave the highest value of WUE (31.32 kg seed yield cm-1 of water consumed). Also, plant population densities at 70000 plants /fad. gave the highest value of WUE. Moreover, Line 3 was more efficient in water use than other genotypes. So, from results of seed yield and WUE, a high or medium irrigation rates with high plant population densities and planted safflower genotype Line 3 are adequate under this study condition.
