Reed canarygrass (Phalaris arundinacea L.) is a naturally widespread grass in Estonia, which so far has successfully been used as a dominant species in the stands of cultural meadows on reclaimed alluvial and peat soils. Because of high and stable dry matter yield through years, in the past decades the species has been started to be used in addition to fodder production also as raw material for cellulose and energy pro-duction. Compared to other grasses, reed canarygrass is characterized by a moderate and unstable seed yield. In the years 2008-2013 a number of experiments was conducted at the Jõgeva Plant Breeding Institute in order to investigate the effect of seeding rate (4, 6, 8, 10 kg ha -1 ), row spacing (15, 30, 45, 60 cm), nitrogen fertilizer rate (N 70, 105, 140 kg ha -1 ) and cutting time of stubble hay (July, October, April) on the seed yield of reed canarygrass. The trial results indicated that when the seed field was established with narrow spacing (15 cm), seeding rate of 4-6 kg ha -1 and nitrogen was applied at the rate of N 140 kg ha -1 , the reed canarygrass "Pedja" yielded in the first two years of use up to 430 kg of seed per hectare. In the following years of use the seed yield dropped drastically. It was expedient to cut the stubble hay at the end of the vegetation period (October) or even next spring (April). Besides the seed yield, it was possible to harvest from the trials 5-8 t ha -1 of dry matter the energetic value of which was 140 GJ. The moisture content of straw harvested in July was 14.5-20.3%, of stubble hay harvested in April 14.3-15.2%. The straw of reed canarygrass as well as the stubble hay harvested in April can be used as energy hay, the sales revenue of which made 12% of the total estimated sales revenue. [ABSTRACT FROM AUTHOR]
