Abstract

5-1- Synopsis
Two successive growing seasons (2013 and 2014) included the experiment in a private farm in Ismailia governorate. The soil wassandy soil, to study the effect of using drip irrigation on the properties of the sunflower oil. Two varieties of sunflower (Sakha 53, Giza 102) were used in the experiments. Four irrigation treatments (0.50, to 1.0 of the – ETo) were applied under drip irrigation system GR, 4 liter perh, diameter 16 mm with 30 cm emitters spacing, by two irrigation systems.The first system was Surface Drip through lines (SDI) and the second was subsurface drip (SSDI) on growth characteristics, yield, WUE and some attributed quality parameters (oil and protein yields, fatty acids composition) of sunflower plants CV. Sakha 53, Giza 102.
5-2- Experiment design
The experimental designwas split-split plot for 3 replicates. The results are discussed for the individual treatments and the interaction between them.
5- 3 - The results
1) The average data of season (1) showed that applying 100% of the ETo (2153 m3 / fed)SSDI, sunflower variety Sakha 53,plantheight was 180.7(cm). The least plant height was 125.4(cm) applying 50% of the ETo(1077 m3 / fed)SDI. Applying 100% of the ETo(1631 m3 / fed)SSDI, sunflower variety Giza102 plant height was 172.5 (cm). The least plant height was 118.1 (cm) when applying 50% of the EToat (816 m3 / fed) by SDI.
2) Season (2) showed that applying 100% of the ETo (1968 m3 / fed) bySSDI sunflower variety Sakha 53 plant,height was 183.1 (cm). The least plant height was 126.3 (cm) when applying 50% of the ETo (984 m3 / fed) SDI. Applying 100% of the ETo (1545 m3 / fed)SSDI sunflower variety of Giza102 plant gaveheight of 173.5 (cm). The l least plant height of 117.6 (cm) was when applying 50% of the ETo (773 m3 / fed) by SDI.
3) The sunflowerhead diameter is season (1) showed that applying 100% of the ETo(2153 m3 / fed)SSDI sunflower variety Sakha 53 gavehigher values of head diameter 24.72(cm) . The lower values of head diameter15.36 (cm) were whenapplying 50% of the ETo (1077 m3 / fed) SDI. Applying 100% of the ETo (1631 m3 / fed)SSDI sunflower variety Giza102 plant height was 21.8 (cm).Lower value of head diameter 10.03 (cm) was with applying 50% of the ETo (816 m3 / fed) bySDI.
4) Season (2) showed that whenapplying 100% of the ETo (1968 m3 / fed) withSSDI, sunflower variety Sakha 53gave head diameter of 24.31 (cm). The least head diameter of 14.19 (cm) waswhen applying 50% of the ETo (984 m3 / fed)SDI. Applying 100% of the ETo (1545 m3 / fed) SSDI, sunflower variety Giza102, plant height was 21.33 (cm). The least head diameter 9.1 (cm) was when applying 50% of the ETo (773 m3 / fed)SDI.
5) The data of season (1) showed that applying 100% of the ETo (2153 m3 / fed)SDI, sunflower variety Sakha 53,mass of seed yield was (kg/fed) (1178 kg/fed).The least weight seed yield (612 kg/fed) was when applying 50% of the ETo(1077 m3 / fed)SDI. Applying 100% of the ETo(1631 m3 / fed)SSDI sunflower variety Giza102, gavemass of seed yield (1055 kg/fed) .The least mass of seed yield was (518 kg/fed) when applying 50% of the ETo (816 m3 / fed) SDI.
6) Season (2) showed that applying 100% of the ETo (1968 m3 / fed)SSDI sunflower variety Sakha 53,mass of seed yield was (1195kg/fed). Lessmass of seed yield was (615 kg/fed) when applying 50% of the ETo (984 m3 / fed) SDI. Applying 100% of the ETo (1545 m3 / fed)SSDI sunflower variety Giza102,mass of seed yield was (1061 kg/fed). The least mass of seed yield was (541 kg/fed) when applying 50% of the ETo (773 m3 / fed) SDI.
7) Fatty acid profile sunflower oil Sakha 53the oleic acid was decreased with increased the linoleic acid in the oil samples were extracted from the seeds those affected by the irrigation method as previously cleared. The total saturated fatty acids not affected by different irrigation methods.Fatty acids profile sunflower oil Giza102no effect was observed between the treated samples and the control sample
5-4- Conclusion
5-4-1- Effect of irrigation systems, water regimes on growth parameters:
Growth parameters showed that subsurface drip irrigation is more compatible for irrigating sunflower plants than surface drip irrigation which gave the highest growth parameters in all experiments.
5-4-2-Effect of irrigation systems, and water regimes onseed mass yield (kg/fed):
Effect of on seed mass yield (kg/fed) showed that subsurface drip irrigation was more compatible for irrigating sunflower plants than surface drip irrigation, which gave the highest mass of seed yield (kg/fed) in all experiments, except 100%ETo; SDI;Sakha53.
5-4-3-Effect of irrigation systems, water regimes on oil% in seed yield:
Effect showed that subsurface drip irrigationwas more compatible for sunflower plants than surface drip irrigation which gave the highest oil% in seed for all experiments.
5-4-4- Effect of irrigation systems, water regimes onprotein in seed yield %:
Effect of irrigation systems, water regimes on protein in seed yield showed that protein percentages varied from 12.7% to 8.5% in the two varieties of sunflower Sakha 53 and Giza 102 in the two seasons.
5-4-5- Effect of irrigation systems, water regimes on oil characteristics:
Effect showed thatall theproduced oil had chemical good quality. That mean, no effect of the experiment of irrigation methods on the chemical sunflower oil quality of those extracted from two hybrid seeds. The oil quality was improved by increasing the Poly unsaturated fatty acids from 58.54 in the content sample to 61.2% in the treated seed. On the other hand variety Giza102 at 100%of the ETo (SSDI) had significantly (p<0.05). The highest oil yield was 43.4% with 70.79 polyunsaturated fatty acid. AU the physico-chemical characteristics of the extracted oil were not affected by the different irrigation treatments. The Acid Value (AV) mg KOH/g oil,Peroxide value (PV) meq.O2/kg oil, Anisidine value AnVmeq./kg oil, TOTOX and refractive indexes at 25ºC were lower than these in the standards .
5-4-6- Effect of irrigation systems, water regimes onWUEofseed yield:
The effect of seed variety Sakha53 WUE was greater in (SSDI) than (SDI), except whenapplying water at 100% of the EToSDI. Also variety Giza102 WUE was greater in (SSDI) than (SDI) and less value of WUE for control with Giza102.The highest value of WUEGiza102 was 0.664 whenapplying water at 50% of the ETo bySSDI.
In the 2ndseason variety Sakha53 WUE was greater in (SSDI) than (SDI). Also variety Giza102 WUE was greater in (SSDI) than (SDI) and less value of WUE was for control.The high value of WUE was with Sakha53when applying water at60% of the ETo(SSDI).The average of two seasons gave 0.677 WUE for seed yield of Sakha53 whenapplying water at 80% of the ETo (SSDI).
5-4-7-Effect of irrigation systems, and water regimes onWUE of oil yield:
Inthe1st season, variety Saka53, WUE of oil was greater in (SSDI) than (SDI) in all treatments. Also variety Giza102 WUE was greater in (SSDI) than (SDI), and the least value of WUE oil variety Giza102 was 0.084 with the control.The highest value of WUE oil yield 0.364 was Sakha53 whenapplying water at80% of the ETo(SSDI).
In the 2ndseason variety Sakha53 WUE was greater in (SSDI) than (SDI). Also variety Giza102 WUE was greater in (SSDI), than (SDI), and the least value of WUE was with the control. Giza102 had0.256highest value of WUEoil yield whenapplying water at 80% of the ETo by (SSDI). But Sakha53had 0.302 whenapplying water at80% of the ETo by(SSDI). The average of two seasons WUE seed yield Sakha53 was 0.283 whenapplying water at80% of the ETo by (SSDI).
