A field experiment was conducted on clay loam soils of Indian Institute of Rice Research (IIRR) formerly Directorate of Rice Research (DRR), Rajendranagar, Hyderabad, Telangana during the kharif seasons of 2017 and 2018, to study the “productivity and water use efficiency of rice cultivars under different irrigation regimes and systems of cultivation” The treatments consisted of two irrigation regimes viz., Alternate wetting and drying and Saturation as main plot treatments, three establishment methods viz., System of Rice Intensification (SRI), Drum Seeding (DS) and Normal transplanting (NTP) as sub plot treatments and four cultivars namely DRR Dhan 42, DRR Dhan 43, MTU-1010 and NLR-34449 as sub-sub plot treatments summing up to 24 treatment combinations laid out in split-split plot design with three replications. Among the cultivars, DRR Dhan 43 recorded significantly highest LAI and CGR at all the crop growth stages in both the years of study and in pooled means as compared to other cultivars. The growth analysis, viz., LAI and CGR were significantly recorded higher in SRI than NTP during both the years of study. Alternative wetting and drying recorded significantly highest LAI and CGR than saturation in all the growth stages.
