MATERIALS AND METHODS
The field experiment was conducted dur- ing the 2004-5 growing season at the ex- perimental farm of the College of Agricul- ture, Shiraz University (Shiraz, Iran,) lo- cated at Badjgah (29?The data collected were subjected to analy-
sis of variance using MSTATC software and using the SAS statistical tech nique.The PGR foliar treatments included CCC at 2.20 kg ha-1 sprayed over the foliage at growth stage (ZGS) 25, (Zadoks et al., 1974) ethephon at 0.28 kg ha-1 sprayed over the foliage at growth stage (ZGS) 39, and the controls (without any PGR) were as-
signed to sub-plots.The measured variables included grain yield (t ha-1), spike m-2, grains plant-1, plant height (cm), spike length (the main shoot spike, cm), LAI (the leaf area was determined with a Leaf Area meter delta T Device model) and dry matter produced (g plant-1).Some physico-7.6, total organic carbon (%) = 1.17, total nitrogen (%)= 0.114, EC (dS m-1) 102
= 0.402, potassium (mg kg-1)= 590, phos-
phorus (mg kg-1)= 26.The seeds were hand-sown in plots 3 m wide and 4 m long that were seeded at the rate of 250 plants/m2 in mid-November.
