Determining the Effect of Sulphur and Boron on Growth and Yield of Boro Rice in Calcareous Soil of Bangladesh| Chapter 7 | Research Highlights in Agricultural Sciences Vol. 4

 The experiment was administered at the field laboratory of Department of Crop Science and Technology, University of Rajshahi, Rajshahi- 6205, Bangladesh all the while the Rabi season from November 2015 to April 2016 to study the effect of Sulphur (S) and Boron (B) on growth and yield efficiency of Boro edible grain (cv. BRRI dhan-28). The experimental region belongs to High Ganges River Floodplain under Agro-Ecological Zone-11 (AEZ-11). The initial field soil was medium arable, silty clay earth and slightly soluble in texture bearing pH 8.4, 1.25% natural resources, 0.10% total N, 16.2 ppm available P, 12.5 ppm possible S, 0.11 ppm Zn, 0.23 ppm B, 0.57 meq/100g K, 4.30 meq/100g Mg, 15.35 meq/100g Ca. The experiment was constructed accompanying two factors namely., factor A (Sulphur) and determinant B (Boron) with three level of doses of each, that is, S0: outside Sulphur (control), S20: 20 kg S/ha, S30: 30 kg S/ha and B0: without Boron (control), B2: 2 kg B/ha, B3: 3 kg B/ha. The experiment was transported in a Randomized Complete Block Design (RCBD) with three replications. In case of Sulphur, the situation S20 (20 kg S/ha) obtained the maximum plant crest (97.811 cm) at harvest, maximum number of tillers hill-1 (26.184) at harvest, maximal panicle distance (24.98 cm), maximum grains panicle-1 (167.37), maximum 1000-grain pressure (27.57g), maximum grain yield (5.46 t/ha) and hay yield (5.71 t/ha), maximum biological yield (11.17 t/ha) and HI (48.88%). Whereas, maximum suffused grains panicle-1 (147.37) and minimum unfilled grains panicle-1 (17.89) were in the direction of S30 (30 kg S/ha). In case of Boron, the highest plant climax (96.378 cm) was about B3 (3 kg B/ha). Highest number of total tiller hilltop-1 (25.149), longest panicle (24.17cm), topmost total grains panicle-1 (165.78), filled grains panicle-1 (144.04) and minimum vacant grains panicle-1 (21.74), maximum 1000-grain burden (25.24g), highest seed, hay and biological yield (4.84, 5.43 and 10.27 t/ha, individually) and highest HI (47.13%) were about B2 (2 kg B/ha).The treatment of S20B2 (20 kg S/ha accompanying 2 kg B/ha) performed best choice response than added situations. So, it can be submitted that S at 20 kg/ha and B at 2 kg/ha with urged dose of NPK and Zn is acceptable for maximum yield of Boro rice in calcareous soils of AEZ-11.
