LENTIL {Lens Cutinaris Medic.) YİELDS IN ERZURUM IN RELATION TO SOVVING DENSITY / ERZURUM ŞARTLARINDA EKİM SIKLIĞININ MERCİMEĞİN (LENS CULİNARİS MEDİC.) VERİMİNE ETKİSİ

SUMMARY : Seed and above ground biomass yields of lentil cv. Kislik Kirmizi -51 were investigated in relation to sowing density (50, 65, 85 and 125 kg seed/ha) under dry conditions in 1988, 1989 and 1990 in Erzurum. Aithough increasing sowing density resulted in high yields, seed yield increased only marginally after 85 kg seed!ha seeding rate. But straw and above ground biomass yields were the highest at 125 kgseedlha. Higher H1 and greater 1000-grain weight compansatedyield disadvantages at lower plant densities. Data are discussed in relation to lentil yields. ERZURUM ŞARTLARINDA EKIM SIKLIĞININ MERCIMEĞIN (LENS CULINARIS MEDIC.) VERIMINE ETKISI OZET : Ekim sikliginin Kislik Kirmizi-51 mercimek cesidinin tane ve toplam (tane-saman) verimi uzerine etkisi Erzurum kirac kosullarinda 1988,1989 and 1990 yillarinda arastirilmistir. Hem tane hem de toplam verim artan ekim dozuna bagli olarak artmistir. Bununla birlikte tane veriminde 85 kg tohum/ha ekim dozundan sonra cok az artis olmustur. Yuksek hasat indeksi ve artan 1000-tane agirligi dusuk ekim dozlarinda verimde azalmayi telafi etmistir. Sonuclar mercimegin verimi acisindan tartisilmistir.
