Abstract
In the pot experiment, performed during 2000–2002 yielding ability of hulless and hulled barley forms was compared in the conditions of controlled water supply. It was found that the highest yield per pot area was obtained from intact barley plants, as well hulless as hulled ones. It resulted from higher number of ear bearing shoots (average more than 5 per plant). Induced reduction of stem number per plant to one or two shoots resulted in yield reduction by 44 to 49 per cent. Thus reduction of tillering for the both barley forms appeared to be a factor of yield reduction. No cultivar response to the number of productive shoots left was stated.
