Abstrakt: The present study aimed to evaluate the impact of planting date on the growth and yield of rice genotypes. The study was conducted during Khaif season of 2022; the field experiment was conducted at the Rice Research Center (RRC) Dokri. The experiment was laid out in split plot design containing three sowing dates' viz. 30thJune, 15th July and 30thJuly in main plots and four rice genotypes viz. NUYT-M-11, N U Y T -M-8, NUYTM-10 and Latify (check) as sub plot treatments. Nevertheless, rice crops sown on June 30th demonstrated markedly superior performance compared to other sowing dates. These crops exhibited a plant height of 97.27 cm, 19.18 tillers per plant, a panicle length of 24.77 cm, a seed index of 29.82 g, a biological yield of 8964 kg/ha, a grain yield of 6000 kg/ha, and a harvest index of 84.11%. The interaction between genotypes and sowing dates significantly influenced the observed plant height, tillers per plant, panicle length, seed index, biological yield, grain yield, and harvest index. Among the genotypes, NUYT-M-11 sown on June 30th displayed the highest values for these parameters. [ABSTRACT FROM AUTHOR]
