Evaluation Yield of Some Varieties of Nigella sativa L. Under Different Climatic Conditions

Abstract

A field study was carried out during the winter season of 2006/ 2007 at experiment farm of Field Crops Department, Collage of Agriculture, University of Baghdad, Abu– Ghraib– to study effect of different sowing dates (15/ 10, 1/ 11, 15/ 11, 1/ 12, 15/ 12, 1 /1) on yield and its components of three varieties of Nigella sativa L. (Iraqian, Syrian, Yemanian). A factorial experiment with a randomized complete block design with four replications was used. The results indicated that Syrian variety was significant at number of branches per plant, capsules/ plant, seeds/ plant, weight of 1000 seeds (gm), yield of seed (kg/ h) (10.62, 8.56, 73.56, 3.247, 424.2) respectively. The sowing date 1/ 12 was significant than the others sown dates at the same characters (9.21, 10.56, 76.85, 3.314, 420.9) respectively. The introduction between Syrian variety and sowing date 1/ 12 was significant at the same characters (11.60, 12.08, 86.85, 3.902, 484.3) respectively.
