AGRICULTURAL CHEMISTRY
Semester: January-June, 2011
An experiment was conducted at the net house of the department of (ieneties and
Plant Breeding. Shcr-e-Bangla Agricultural University. Dhaka-I207 under potculture
during the Dora season (December-June) of the year 2010-Il to swdy the
effects of salinity on morphology and mineral content in shoots of some rice cultivar.
The experiment was completed using live varieties (Jatabalam. Chapsal. Kolarmocha.
BINA dhan 8 and BRRI dhan4l) and live salinity levels (0. 3. 6. 9 and 12
dSm1). The experiment was set in Completely Randomized Design (CRD) having
two factors with three replications. The plant height, total tiller number. shoot dry
weight, root dry weight, effective tiller, grain weight were highest in genotypes
BRRI dhan4 1 but Kolar-mocha showed the lowest performance under different
salinity levels. The highest concentration of Na. Ca2'and Mg2 was in Kolar-mocha
and it was lowest in BRRI dhan4l. The shoot of BRRI dhan4l contained the highest
concentration of W. Conversely. Kolar-mocha contained the lowest amount of K.
The plant height. total tiller number, shoot dry weight, root dry weight, elThctive
tiller. filled grain, grain weight were highest mO dSmd level of salinity. The highest
K content in shoot (1.64%) was recorded in 0 dSm4. The highest Na content in shoot
(1.584%) was recorded in 12 dSni' level of salinity. The Ca content recorded in
shoot was highest (1.07 %) in 6dSnf'. 'the lowest Mg (0.35%) content was in the
shoot in 0 dSm'. The highest panicle length and filled grain panicle'' was recorded
in BRRI dhan4l at 0 dSm4 level of salinity. The minimum number of unfilled grain
panicle" was found in BRRI dhan4l at 0 dSm". The highest grain yield hilr' (5.00
g) was found in BRRI dhan4l at 0 dSm" salinity level. The lowest Na content
(0.78%). Ca content (0.75%) and Mg content (0.33%) in shoot was found in the
cultivar BRRI dhan4l at the 0 dSm" salinity level. Considering the above results
cultivar BRRI dhan4l and BINA dhan S were salt tolerant. Chapsal as moderately
tolerant and Kolar-mocha and Jatahalam as susceptible cultivar.
