Growth and Productivity of Some Sorghum Cultivars under Saline Soil Condition.

Abstract

A field experiment was performed during the two consecutive summer seasons of 2006 and 2007 to study the effect of sorghum cultivars and soil salinity on growth, yield and its components. Experiment were carried out in Ebshway Fayoum Governorate, Egypt.1. Sorghum cultivars (i.e. Giza 115, Bioneer, Dorado and Horas) significantly differed in growth characters at 40, 70 and 100 days after sowing, as, well as yield and its components. Both Giza 115 and Horas cultivars surpassed the other sorghum cultivars in most cases. 2. Increasing in soil salinity level from 2400 to 2800 and/or 3320 ppm induced significantly decrease in all growth characters studied at 40, 70 and 100 days age, as well as, yield and its components. 3. The interaction between sorghum cultivars and soil salinity level were significant for all growth characters studied at 40, 70 and 100 days from sowing and yield and its components. The salt tolerance was raising with Giza 115 and Horas cultivars. Base on the results Giza 115 and Horas cultivars is recommended to be planted under soil salinity conditions.
