This period of life cycle of sorghum in Alhogaria district, Taiz province, normally reaches about 170 days starting from May 1st up to mid of October. Plant gets a dry period lying from middle of June until August 1st. So, plants would not benefit from the second main rain period ( August 1st up to end of September). To catch up this period and avail of, a study was carried out by means of planting 7 wheat varieties of short life cycle, and Sonalika Variety ( control), in two consecutive seasons at Haifan region ( one location), and Al-Ghalibh region (two location) on the first week of August 2004 and 2005. Harvest of sorghum and all wheat varieties occur in both regions at third part of October 2004 and 2005 respectively. Experimental varieties, 1, 2, 4 and 10, and the control completed their life cycle on this date. While the 7, 22 and 27 varieties were still at paste stage. They received direct rain depth from swing date until harvesting 210 and 225 mm in Haifan region and 184 and 190 mm in Al-Ghaliba region for both seasons (2004 and 2005 respectively). The output of 2004 season was better than 2005 for all varieties in both regions. Results have shown significant differences, except the straw, in all locations in 2005 season and only in Haifan plot in 2004 season. There is an important need to go into wide trial program using the four varieties (1, 2, 4, and 10) under all similar environments.
