Effect Of Seeding Rates and Nitrogen Level On Phenology, Growth And Yield Of Sakha 101 and Sakha 102 Rice Cultivars Under Broadcast- Seeded Rice
Abstract: ABSTRACT

Two field experiments were conducted at the experimental farm of Rice Research and Training Center, Sakha, Kafr El-Sheikh, Egypt during 2002 and 2003 season to study the effect of seeding rate Viz, 31,40,50and 60 kg/ fed. (71, 95,119 and 143 kg / ha.). And nitrogen level Viz, 0, 23, 46, 69 and 92 kg N/fed. (0, 55, 110, 164 and 219 kg N / ha) on phenology, growth and yield of Sakha 101 and Sakha 102 rice cultivars. The days from sowing up to maximum tillering stage, panicle initiation and heading were estimated. In addition, chlorophyll content, leaf area index, yield and yield components were determined. The main results could be summarized as follow: nitrogen level and seeding rate significantly affected all above mentioned traits. The highest values of growth characters, yield components and grain yield were obtained with the highest nitrogen level (219 kg / ha). Increasing nitrogen level delayed the plant phenology (i.e. the highest seed rate and nitrogen level prolonged the plant phenology). The optimum seed rate was 114 kg seed/ ha. Sakha 101 rice cultivar performed better than Sakha 102. Beside, Sakha 101 had the longest periods from sowing up to maximum tillering stage (MT), panicle initiation (PI) and heading date (HD).
