Field experiment was conducted at Kadisaea Governorate to investigate effect of three swing rates (100, 140 and 180 kg. ha) on growth and yield of four rice cultivars (Anber- 33, Anber Menathera, Anber Baghdad and Anber Furat).
The results indicated that Anber Baghdad C. V. gave significant increment in plant height, number of panicles per m2, weight of 1000 grains and yield. The cultivar of Anber Menathera gave largest flag leaf area and highest number of grains per panicle.
Sowing rate (180 kg. ha-1) superior in no. days (planting to 50% flowering), FLA (Flag Leaf Area), No. panicle per m2, which rwflected in highest yield.
Data showed significant interaction between sowing rate and cultivars, and that increasing of sowing rate of CV. Anber Baghdad to 180 kg/ ha, encouraged the plant to posses highest No. panciles/ m2 No. grain/panicle, weight of 1000 grain, so these all reflect in highest yield.
