| Abstract | Climate and land use change are responsible for causing in water scarcity in rice production. Water-saving technologies are the solution of this problem. This technology requires integrated management with variety and N fertilizer. The objective of this research was to assess growth, yield and N uptake of rice under different N application timings, cultivation methods and varieties. This research was conducted in the greenhouse. Pots were arranged in a completely randomized design. The experiment was composed of three factors; i) timing application of nitrogen (T1 = 100 % basal, T2 = 75 % basal + 25 % at active tillering, T3 = 50 % basal + 25 % at active tillering + 25 % at panicle initiation, T4 = 25 % basal + 25 % at active tillering + 25 % at panicle initiation + 25 % at flowering), ii) cultivation method (C1= transplanting, C2 = wet-direct seeding, C3 = dry-direct seeding), iii) variety (V1 = Pathumthani 1, V2 = RD 57). Parameters measured in this research were plant growth, yield components, and N uptake. Splitting of N application resulted in higher yield than 100% basal and T3 provided the highest yield (37.6 g/plant). Three-way interactions were significant on three variables; (i) shoot dry matter with the combination of dry-direct seeding, T2 and RD 57 resulted in the highest biomass (42.6 g), (ii) straw N content with the combination dry-direct seeding, T1 and Pathumthani 1 had the highest (0.63) and (iii) grain N content with the combination dry-direct seeding, T4 and Pathumtani 1 had 1.32. |
