EFFECT OF SULPHUR AND ZINC ON THE YIELD AND NUTRIENT CONTENT OF T.AMAN RICE (Oryza saliva)

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.
