| Abstract | ||||
| Four field experiments were conducted at the Experiment and Research Center, Fac. Agric., Moshtohor, Benha Univ., Kalubia Governorate and Rice Research and Training Center, Sakha, Kafrelsheikh Governorate, Egypt in the two successive seasons 2011 and 2012 to study the performance of five new genotypes of rice under three irrigation intervals on yield and yield attributes. The most important results obtained from this study can be summarized as follows: The highest values were recorded under irrigation intervals of 3 days, followed by irrigation every 6 days, however, the extra of the studied traits increasing irrigation intervals to 9 days significantly reduced the obtained characters values for all of the studied characters in both seasons under the two locations. Results showed that irrigation each 3 days allover the growing season gave reasonable production compared with irrigation every 6 and 9 days. The GZ7576 genotype was of the earliest heading compared with the other rice genotypes in both seasons. While, Sakha106 genotype gave the highest values of root length, No. of panicles hill-1, No. of panicles m-2, panicle length, No. of grains panical-1, grain index and grain yield fed-1 in the both seasons at two locations. Significant interaction effect for irrigation intervals and rice genotypes was obtained for No. of panicles m-2 in the first season and heading date, No. of panicles hill-1, panicle length, No. of grains panical-1 and grain index in the second season at Moshtohor location. While, No. of panicles hill-1 in the both seasons and No. of panicles m-2and grain yield fed-1 in the first season were significantly affect by the interaction between irrigation intervals and rice genotypes at Kafrelshiekh location. Generally, irrigation every 3 days under Sakha 106 genotype treatment recorded the highest values for the studied traits in both seasons at two locations. | ||||
