Abstract

A field trial was conducted in a private farm at AL-Hilla, Iraq during the growing season 2014-2015. The objective of this study was to investigate the foliar application of ethephon and gibberellin on growth and yield of wheat (Triticum aestivum L.) cultivar Iba.99 planted in different dates. Results of this experiment revealed that: application of ethephon (GR2) caused a significant increase in grain yield (an average) of 3.754 t ha-1 due to its superiority in one of the main components (number of spike.m-2) which was amounted to 328.25 spike m-2 as a result of increased number of tillers (377.18 tiller m-2). However, gibberellin (GR1) had significant increase in the weight of thousand grain (38.26 g). Planting date in November 18 (D3) significantly increased the grain yield to 5.25 tons. ha-1 due to high values of grain yield components. Most growth traits, were reflected in an increased biological yield. There was a significant interaction between planting dates and plant growth regulators (ethephon and gibberellin) in all traits, except spike length.
