| Abstract | ||
| A field experiment was conducted at the field of the Department of Field Crop Science university of Baghdad during two winter successive seasons of 20072008 and 20082009.The objective was to study the effect of four sowing dates 510, 1510, 511 and 1511 on yield, umbellet no., umbel no., fruit no. and thousand fruit weight of two cultivars of caraway common (Iraqi) grown wildly in northern west of Iraq and balady (Egyptian) sown in Syria . RCBD was used under factorial experiment with three replicates. Results showed that the first date was superior in umbellets no. 14.65 and 14.77 umbellet. umbel-1, for each season, respectively. While, the second date gave highest fruit yield of 985.6 and 992.8 kg.h-1 for each season, respectively. Iraqi cultivar was superior in thousand fruit weight of 7.19 and 7.35g, and fruit yield of 954.8 and 962.5 kg.h-1. While balady gave highest umbels no. of 62.52 and 67.74 umbel.plant-1, for each season, respectively. Also, the interaction of first date X Iraqi cultivar was superior in umbellets of 15.00 and 15.63 umbellets.umbel-1,umbels of 68.2 and 70.3 umbel.plant-1and fruits yield of 1083.00 and 1092.00 kg.h-1 It concluded that the best date to sow caraway was 5/10 and the best cultivar was Iraqi.Therefore, it was recommended to sow Iraqi cultivar seeds upto 15/10.Also,it is very important to subjected Iraqi cultivar to breeding and improvement program via selection to obtain Iraqi genotypes had high yield | ||
