A field experiment was carried out at the Bangladesh Agricultural University Farm, Mymensingh, Bangladesh during Boro season of 2000 to evaluate the comparative effect between one or two layers of incorporated Azolla biomass from 0.2 and 0.1 kg m‾2 inoculum with 50 kg N ha-1 as urea and the recommended dose of N (100 kg ha-1) on the yield and NPS uptake of BRRI Dhan 29. All the treatments were tried in two different plant spacings i.e., S1: 25-25×15 cm and S2: 35-15×15 cm. The highest grain yield of 4.43 t ha-1 produced by two incorporations of Azolla @ 0.2 kg m‾2 inoculum with 50 kg N ha-1as urea, which differed significantly from 4.06 t ha-1yield produced by 100 kg N ha-1 as urea (the recommended dose). But the yield of 3.88 t ha-1produced by twice incorporation of Azolla @ 0.1 kg m‾2 inoculum with 50 kg N ha-1 as urea and the yield from one incorporation of Azolla @ 0.1 and 0.2 kg m‾2 inoculum plus 50 kg N ha-1 as urea (3.65 and 3.91 t ha-1, respectively) did not differ statistically with that of 100 kg N ha-1as urea. The lowest grain yield of 2.26 t ha-1 was recorded from the control. The nitrogen, phosphorus and sulfur (NPS) uptake in grain and straw increased significantly by about 40-84, 45.3-109 and 41-87%, respectively, due to incorporation of Azolla over control. The difference between two plant spacings was not significant. Interaction effect between plant spacing and Azolla-urea treatments also did not exhibit any significant variation. |
