Abstract :

Appropriate management of planting dates for each cultivar is necessary for enhancing site productivity in forage sorghum plantation. To investigate the effects of planting dates on yield components and protein percentage of sorghum cultivars, an experiment was conducted at Research Farm of Isfahan University of Technology, Lavark in 2013. A split plot design in the layout randomized complete block design with three replications was used. The main plots were concluded 15th June and 30th June, and subplots were 4 cultivars, namely, Sarasai, Speedfeed, Pegah and Sofera. Planting date had significant effect on plant height, LAI, total fresh yield and stem dry yield. The effects of cultivar significant on plant height, LAI, stem fresh yield, leaf fresh yield, total fresh yield, stem dry yield and total dry yield. Protein percentage was not influenced by both planting date and cultivar, and there was no trend in this treatment. Stem fresh yield, leaf fresh yield, total fresh yield, stem dry yield, leaf dry yield and total dry yield was significantly influenced by planting date and cultivar. On the basis of the results, it seems that cultivation of Speedfeed because of its high fresh and dry forage production in 30th June is suitable. The forage and protein percentage of three other cultivars are the same and there were no differences between them.
