Effect of rates of sowing and four varieties on yield and yield components of Nigella Sativa L.

Abstract

A field experiment was carried out during the winter season of 2002 / 2003 at the Groups department College of Agriculture, university of Baghdad, Abu-Graib, to study Effect of four rates of sowing (6 , 8 , 10 , 12kg / ha)and four varieties on yield and yield component of Nigella Sativa L. A factorial experiment with a randomized complete block design with four replications was used. The treatments were four varieties of Nigella Sativa L. Iranians (V1), Iranian (V2), Yemenian (V3), Syrian (V4) Varieties. And four rates of sassing (6 (S1), 8 (S2), 10 (S3), 12 (12) kg / ha) The results indicated that (S4) was significant at height of plant (51.11 cm), rate of seeds in capsule (57.41), number of branches per plant (8.6) number of (5.5) and the yield of seeds 319.62 kg/ha .The variety (V2)was significant at yield (337.74kg/ha)and number of seeds per capsule (53.11).The variety (V3)was significant at number of branches per plant(11.13) . The interaction between the variety (V2) and the rate of sowing (S2) was significant at the yield of seeds (471.38 kg / ha).
