Abstract
A field study was carried out during 2010 and 2011growig seasons in the oasis of number - 43- of the desert oases project – Haditha location - (260 km) West of Baghdad. the determine the effect of seeding rates (4,6 and8)kg.h-1 and rows spacing between the rows (30,40 and50) cm on the rapeseed crop in desert soil and irrigation wells water in the western of Iraq. A split plot design in RCBD was used in the replicates. Seeding rate were considered as the main plots while the row spacings as subplots. Data were obtained on some growth characters (plant height and number of primary branches) and seed yield and its components (number of pods, number of seeds in pods and weight 1000 seeds). Results showed that plant height with seeding rate of 8kg.h-1 was increased significantly (103.3) cm at the first season and 4kg.h-1 (6.9) branches .plant-1 at the second season. Row spacing 30cm showed higher values for plant height (105.7 and 104.8) cm gave for the two seasons respectively as results showed that number of pods (250.4 and 272.0) pod.plant-1, weight 1000 seed (2.16and 2.50) gm and seed yield (820.2and 923.7) kg.h-1with seeding rat of 4kg.h-1 were increased significantly for the two seasons respectively and number seeds (26.6) seed.pod-1at the second season. Row spacing 40 cm higher values for weight 1000 seed (2.16 and 2.50) gm gave for the two season respectively, number of pods (248.06) pod.plant-1 at the second season , while row spacing 50cm higher values for number of seed (25.8) seed .pod-1 and total seed yield (925.8) kg.h-1 gave for the first season and number of pods (270.3) pod.plant-1 at the second season. The results showed that there are response for this crop in the desert soil and wells water conditions and significant differences in the growth characters such as plant height, number of branches, seed yield and its component the effect of seeding rates and row spacings.
