Abstract:
A field experiment was conducted at Sher-e-bangla Agricultural University
research farm,Sher-e-bangla nagar, Dhaka from July - November, 2011 with
the objective of evaluating the effect of S and Zn on the yield and nutrient
content of T-Aman Rice. The experiment compared with thur different
individual and combined treatment (sixteen) of sulphur vii S0 (control). Sg (8 kg
ha5. S12 (12 kg ha") and S16 (16 kg ha4) and zinc vii Zn0 (0kg haj, Zn10 (1.0
kg ha1), Zn15 (1.5 kg ha4) and Zn2.0 (2.0 kg ha4) on yield performance and
nutrient content of rice . The experiment was laid out in a randomized
complete block design(RCBD). All plots received recommended doses of N,
P. and K to support normal plant growth and yield. N. P. K. S. and Zn were
applied in the form of Urea. TSP, MOP, Gypsum, and ZnSO4. respectively.
The application of sulphur and zinc had a positive significant efThct on all
yield contributing characters viz, plant height. tillers hilr', panicle length,
grains panicle", 1000-grains weight, grain and straw yield. The longest plant
(124.0 cm), highest grain yield (5.663 t ha4) and straw yield (8.163 t ha4) of
T-Aman Rice was recorded in S12Zn15 (12 kg S ha" + 1.5 kg Zn ha'). The
application of sulphur and zinc fertilizer significantly increased the S and Zn
contents in soil. Overall results indicate that the treatment combination of
S12Zn, 5( 12 kg S ha" and 1.5 kg Zn haTM alone or combincdly was more
effective to produce higher yield and more nutrient of' T-Aman rice
supported with recommended doses of N, F, and K under the agroclimatie
condition of SAU.
