Title : Effect of age of seedlings on normal rice genotypes at RARS, Tarahara (1995/96) Material Type: printed text Authors: Mahato, R.K. ; Pathic, D.S, Author Pagination: 75-76 p. Languages : English (eng) Abstract: The field experiment was carried out at RARS, Tarahara in split plot design with four
replications to find out the optimum age of seedlings for promising normal season rice
genotypes in ETR. Four genotypes (BR-153, NR601-1-3-1-2, RP1017 and OR-142) were
assigned in main plots and five different seedling ages (20 days, 30 days 40 days 50 days and
60 days) were allotted in sub-plots. The result revealed the significant effect on grain yield
due to age of seedlings. Thirty days old seedlings produced highest grain yield (4.12 t/ha)
irrespective of tested genotypes. The interaction effect between age of seedling and
genotypes was also found highly significant. Genotype RP-1017 was observed to be the
highest yielder (4.89 t/ha) at 40 days old seedling followed by NR 601-1-3-1-2 (4.69 t/ha) at
20 days old seedling. The genotypes BR-153, NR 601 and OR:-142 showed at par yield while
planting 20-50 days old seedlings. But RP-1 017 failed to produce good yield when 20 days
old seedling was transplanted. However, its yield was at par with 30,40, 50 and 60 days old
seedling. Hence this genotype may suit for the older seedling transplanting incase of erratic
rainfall condition.Effect of age of seedlings on normal rice genotypes at RARS, Tarahara (1995/96) [printed text] / Mahato, R.K. ; Pathic, D.S, Author . - [s.d.] . - 75-76 p.
