Abstract
Two field experiments were conducted at The Experimental Farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt during 2013 and 2014 summer seasons to study the effect of planting methods and irrigation intervals on the productivity of some rice cultivars. The experiments were laid out in a strip split-plot design with four replications. The main plots were devoted to two methods of planting (transplanting and drilling), while the horizontal plots were devoted to irrigation intervals were as follows (Continuous flooding every 4 days, Irrigation every 8 days and Irrigation every 12 days), the sub sub-plots were occupied by three rice cultivars (EHR, Giza179 and Giza177). The results could be summered as follow, the transplanting method with irrigation every 4 days recorded the heights values of Leaf area index, chlorophyll content, dry matter production, days to50% heading, plant height, No.of tillers, grain yield and most of its components as well as grain quality followed by drilling method with irrigation every 4 days. EHR1 recorded the highest growth characters, grain yield and its components and followed by Giza179,. While, Giza 177 recorded the highest grain quality.
