A field experiment was carried out in order to assess the performance (growth, yield, and yield-attributing characteristics) of five different spring rice genotypes. The study was conducted in a farmer’s field in Bagdula, Pyuthan, under the supervision of Prime Minister Agriculture Modernization Project (PMAMP), Rice Zone, Pyuthan, from March 2021–July 2021. Five spring rice genotypes, including PR-126, HHZ 25-DT9-Y1-Y1, IR 103575-76-1-1-B, IR 99742:2-11-17-1-9-B, and IR 86515-19-1-2-1-1-1-1, were evaluated in a randomized complete block design (RCBD) with four replications each. Plant growth and yield-attributing parameters were measured, entered into MS-Excel, and analyzed using the R-Studio software. Rice seedlings were raised in a wet nursery bed and transplanted at a spacing of 20 cm x 20 cm (3 seedlings per hill). The highest plant height (82.25 cm) and number of tillers per hi...
