Abstract
A field experiment was carried out in 2006 to investigate the effect of harvesting time and main plant residual on yield and yield components of rice. A split-split plot arrangement fitted into a Randomized Completely Block Design with three replications was used. Main factor was 3 harvesting times (T1 : harvesting plant crop at physiological maturity T2 : harvesting at 7 days after physiological maturity. T3 : harvesting at 14 days after physiological maturity). Sub-factor was 3 varieties (Traditional Tarom, Deylamani Tarom, Black Tip Tarom) and with plant residual in three levels (cutting from soil surface, lodging method, control (no treatment on residual) as a Sub-sub factor. Results showed that plant height, total tillers , fertile tiller, filled spikeletes percentage, and ratoon grain yield were decreased with delayed harvesting time. The highest ratoon grain yield was obtained in traditional Tarom variety. Most and least ratoon grain yields were produced in laying method and control respectively. Interaction effect of harvesting time , variety and main plant residual had no significant effect on rice ratooning characterisrics. Rice ratooning grain yield had positive and significant correlation with total tiller and panicles number per m2.
