Abstract

In order to study the effect of irrigation levels and application of methanol and nano iron oxide on yield and grain filling components of sunflower (Helianthus annuus L. ), a factorial experiment has been conducted based on randomized complete block design with three replications at the research farm of Islamic Azad University, Ardabil Branch, within 2017. The experimental factors include application of methanol (Foliar application with water as control along with 20 and 30 volume percentage), nano iron oxide (Foliar application with water as control as well as application of 0. 3, 0. 6, and 0. 9 g. L-1), and irrigation levels (full irrigation as control, irrigation withholding at flowering stage, and irrigation withholding at grain filling period). Results show that the highest grain yield (2952 kg/ha), number of filled grains per head (1121 grains per head), 1000-grain weight (50 g), rate and grain filling period, effective grain filling period (i. e., 0. 00239 g/day, 42, and 33 days, respectively), and chlorophyll index (56) have been obtained in full irrigation and high levels of methanol and nano iron oxide, with maximum proline and soluble sugars content (11. 1 μ g/g FW and 72 mg/g FW) belonging to irrigation withholding at flowering stage and application of high rates of methanol and nano iron oxide. The minimum rates of these have also been obtained in full irrigation without any application of methanol and nano iron oxide.
