INFLUENCE OF SULPHUR AND ZINC ON THE YIELD OF T. AMAN RICE (BRRI dhan34)

Abstract

The experiment was conducted in the Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from June to November 2013 to find out the influence of sulphur and zinc on yield of transplanted (T.) aman rice. BRRI dhan34 was used as the test crop in this experiment. The experiment consisted of two factors. Factor A: 3 levels of sulphur (S 0 : 0 kg S ha -1 , S 1 : 8.0 kg S ha -1 , S 2 : 12.0 kg S ha ) and Factor B: 4 levels of zinc (Zn 0 : 0 kg Zn ha -1 , Zn 1 : 1.0 kg Zn ha -1 , Zn , Zn 3 : 3.0 kg Zn ha -1 2 -1 : 2.0 kg Zn ha ). The experiment was laid out in a randomized complete block design (RCBD) with three replications. In case of sulphur fertilizer, the highest yield and yield contributing characters were observed from S , whereas the lowest was recorded from S 0 2 . For different levels of zinc, the highest yield and yield contributing characters were observed were recorded from Zn , whereas the lowest was recorded from from Zn 0 3 . Due to the interaction effect of different levels of sulphur and zinc, at 30, 45, 60, 75 DAT and harvest, the tallest plant (26.65, 54.48, 87.32, 98.67 and 122.53 cm, respectively), the maximum number of total tillers hill (20.60), the longest panicle (29.65 cm), the highest grain yield (4.00 t ha -1 ), the highest straw yield (5.36 t ha -1 ) and the maximum uptake by grain for N (38.45 kg ha -1 -1 ), P (15.93 kg ha ), K (19.79 kg ha -1 ), S (6.36 kg ha -1 ) and Zn (0.819 kg ha -1 ) were recorded from S , whereas the shortest plant (16.89, 45.09, 63.66, 81.05 and 103.81 cm, respectively), the minimum number of total tillers hill -1 (13.13), the shortest panicle (20.23 cm), the lowest grain yield (2.13 t ha -1 ), lowest (3.88 t ha -1 ) and the minimum uptake by grain for N (12.55 kg ha kg ha -1 -1 ), P (6.08 kg ha ) was recorded from S 0 Zn 0 -1 ), K (9.85 kg ha -1 ), S (3.48 kg ha . Therefore, a package of 8.0 kg S ha -1 along with 2.0 kg Zn ha -1 may be recommended for T. aman cultivation in Shallow Red Brown Terrace Soil under Madhupur Tract (AEZ-28) of Dhaka district. 2 -1 -1 Zn ) and Zn (0.287 -1 3
