Abstract

The current study was conducted to investigate the effects of different soil fertility treatments onqualitative and quantitative yield of sunflower (Helianthus annus L. ) under different irrigation regimes. The experiment was conducted in Tarbiat Modares University research field at 2012 and 2013 growingseason. Treatments were arranged as split plots based on a randomized complete block design with threereplicates. Irrigation regimes, (irrigation after consuming 30% (I1), irrigation after consuming 50% (I2)and irrigation after consuming 70% (I3) of available soil moisture) were randomly assigned to the mainplots and the subplots were eight different fertilizer types (providing 100% of plant NITROGEN requirementfrom urea as chemical fertilizer (F1), combination of chemical fertilizer and cattle manure (F2), ZEOCOMPOST (F3), VERMICOMPOST (F4), ZEOPONIX (F5), combination of ZEOCOMPOST and VERMICOMPOST (F6)combination of ZEOCOMPOST and ZEOPONIX (F7), combination of VERMICOMPOST and ZEOPONIX (F8)). Theresults indicated that the maximum seed yield was obtained in normal irrigation treatment (irrigation afterconsuming 30% of available soil moisture). Under WATER DEFICIT STRESS conditions (irrigation afterconsuming 50 and 70% of available soil moisture), organic treatments amended with more zeolite(zeocompost, ZEOPONIX and ZEOCOMPOST + ZEOPONIX) improved seed yield. Under severe water deficitstress condition (I3), zeolite-amended organic treatments (zeocompost, ZEOPONIX and ZEOCOMPOST +zeoponix) increased seed oil percentage by 8, 9 and 13 percent in the first year and by 13, 10 and 12percent in the second year of the experiment in comparison with chemical treatment (F1). In addition, organic treatments improved oil quality through increasing linoleic and oleic acid percentage. Overall, theresults suggest that combined application of processed organic fertilizers such as VERMICOMPOST, ZEOCOMPOST and ZEOPONIX not only increases sunflower seed yield and oil quality but also reduceschemical fertilizers need in sunflower production.
