Abstract

This experiment was conducted in Safi Abad Agricultural Research Center of Dezful in order to study the effect of seed deterioration and plant density on germination, seedling establishment, yield and yield components of hull-less barley with in 2011- 2012. Treatments included three levels of seed deterioration: (control, 72 and 96 hours) and five plant densities (100, 150, 200, 250 and 300 plants per m2). Results showed that the seed deterioration significantly affected variables of 1000 grain weight, spikes number per m2, fiber percentage, protein percentage, biological yield, grain yield and harvest index (HI) was significant. Further more, plant density significantly affected spike number per m2, 1000 grain weight, grain yield, harvest index, fiber percentage, protein percentage and biological yield. It can be concluded that use high quality of seeds, in addition to the plants during growth and development, result in yield increase.
