OZET: Erzurum kosullarinda 1997-98 ve 1998-99 orun yillarinda yurutulen bu arastirmada; serpme ekim, derin kariga ekim, duz mibzerle ekim ve baskili mibzerle ekimyontemlerinin bugdayin verim ve verim unsurlarina etkisi incelenmistir. Ekim yontemleri iane verimi ve verim unsurlarini onemli derecede etkilemistir. Serpme ekim, derin kariga ekim, duz mibzerle ekim ve baskili mibzerle /kimde m2'deki basak sayisi sirasiyla 285.9, 378,1, 378.8 ve 436.3; basaktaki tane sayisi 14.3, 15.9, 14.5 ve 15.0; bin tane agirligi 39.0, 40.4, 38.5 ve 38.9 g ; tane verimi ise 142.2, 190.6, 187.6 ve 213.3 kg/da olmustur. En yuksek tane verimi baskili mibzerle ekim yonteminden elde edilmistir. Ekfm yontemleri arasindaki tane verimi vatyssyonlan m1'deki basak sayisi i/e ilgili bulunmus ve Erzurum yoresi kuru tarim kosullari Icin, baskili mibzerle ekimyontemi onerilmistir.

The effects of seeding methods on grain yield and yield components vvere significanl. The spike numbers per m'' were 285.9. 378.1, 378.8 and 436.3; kernel numbers per spike were 14.3, 15.9, 14.5 and 15,0; thousand kernel vveights vvere 39.0, 40.4, 38.5 and 38.9 g, and grainyields vvere 142.2, l 90.6, I 87.6 and 2 13.3 kg/da respectively in hand spreading, deep bed seeding, seeding by normal drill and press drill methods. The highest grain yield was obtained from press drill seeding method. Variation among the seeding methods in grain yield vvas associated with soike number per m2. Press drill seeding is, Iherefore, recommended in Erzurum diy Tarming conditions for high grainyields. Key vvords: Seeding methods, yield andyield components, vvheat
