Abstract
In order to investigate the effect of sowing dates on rice yield and its components a field experiment was carried out in Randomized Complete Block Design (RCBD) with three replications at the Experimental Farm of Sakha Agricultural Research Station, Sakha, Kafr EL-Sheikh Egypt. 14 rice genotypes were tested at different sowing dates, April 1st, April 15th, May 1st and May 15th during the two successive rice seasons 2017 and 2018. The studied characters were i.e., flag leaf area, chlorophyll content, plant height, number of panicles per hill, number of filled grains per panicle, number of unfilled spikelets per panicle, 1000-grain weight (g), grain yield (t/ha), number of days from sowing to heading and growth degree days. Analysis of variance indicated that rice genotypes were significantly different for all the studied traits. The highest values of grain yield and most of the studied characters were observed under April 15th followed by May 1st sowing dates. Sakha108 and GZ6903-1-2-2-1 produced the highest grain yield followed by IR77510-68-1-3-3.
