Abstract:
A held experiment was conducted at Sher-e-Bangla Agricultural University farm.
t)haka from July to October 2007 with an objective of evaluating the effect of S and Zn
(in the yield .yield components and nutrient uptake by T-Aman (13Rltl dhan3l ).The soil
was silt loam having p1 -1 5.7. 1 18% organic maIler, lb ppm available S and 0.8 ppm
available Zn contents. Ihere were twelve treatnienis taking various doses of Sulphur
and Zinc viz. Sizno (control). SZni, SZ02. S12Zn0. S127n , S12Zn2. SiZim. Si6Zn.
S/m, SmZn, S2Zni. S,Zn,. •Fhe subscripts represent doses in Kg/ha. The treatments
were laid Out in a randomized block design with three replications. All plots received
recommended doses of N. P. and K to support nonnal plant growth. N. P. K. S. and Zn
were applied in the fonn of Urea. I.S.P. MOP. Gypsum. and ZnSO4 respectively, the
application of Sulphur and Zinc had a positive significant effect on lillers/hill. plant
height. panicle length and no. of grains/panicte. The highest grain yield (4.20 c/ha) and
straw yield (5.62 tiha) of BRR! dhan 31 was recorded in S1uZ,,: treatment. The So4u
treatment (control) had the lowest grain (3.01 tiha) and straw yield (4.50 c/ha). [he
application of Sulphur and Zn fertilizers signilicantly increased the S and Zn contents
as well as their uptake by rice crop. Over all results indicate that the application of
Sulphur and Zn at it rate of 20 kg S and 2 kg Zn per hectare along with recommended
dose of N. P. and K is necessary for obtaining maximum grain yield as well as straw
yield of T-Anian rice.
