| Abstract | ||||
| Field Experiment was carried out in summer seasons of 2014 and 2015 at the Experimental Farm of Rice Research Section, El-Gemmiza, Agricultural Research station, El-Gemmiza, Gharbia Governorate, Egypt. This fulfillment was conducted to study the response of three rice genotypes (Sakha 106, Giza 179 and Hybrid 3), two types of fertilization (chemical and compost fertilization), weeding control (hand weeding and chemical control) and plant density (one, two and three plants/hill) on yield and its attributes traits. Genotypes significantly differed in all studied traits. Hybrid 3 genotype produced the maximum values of No. of tillers and panicles/m², length of panicle , No. of total grains for panicle and 1000- grain weight as well as yield of grain/fed). While, the lowest values of these traits were recorded with Sakha 106 genotype. Chemical fertilization had significant effect on some of studied charactars. Weeding control treatments had non-significant effects on all studied characters, except No. of tillers/m² and length of panicle in the 1st season. Three plants/hill produced the highest values, while the lowest values of the previous traits were obtained when using one plant/hill. In general, it could be recommended that planting Hybrid 3 genotype as one plant/hill, Giza 179 genotype as two plants/hill and sakha 106 genotype as three plants/hill and organic fertilized with compost and using hand weeding under the new treatments of system of rice intensification. | ||||
