Rice Genotypes, Raising of Seedlings, Transplantation, and
Management Practices. Forty-three upland rice genotypes
(Table 1) obtained fromthe International Rice Research Institute
(IRRI) and Bangladesh Rice Research Institute (BRRI)
were used in this study. Thirty sun-dried seeds of each
genotype were treated with 70% ethanol for 90 s to control
seed-borne diseases and were placed on moist filter paper in
Petri dishes for germination. After germination, ten-day-old
seedlings were transplanted into the tank. Only one seedling
per hill was transplanted and each replicate consisted of two
hills for each genotype. The interplant and interrow distance
was maintained at 20 cm.Management practices such as irrigation,
fertilization, weeding, and spraying were performed
by following the standard procedures of the IRRI [11].
