Field condition A field experiment was conducted using BRRI dhan47 variety of rice in saline soil at Musulliabad, Kalapara, Patuakhali during January to May (Boro Season), 2016. The site enjoys a tropical monsoon climate and has three main seasons, namely, the monsoon or rainy season, the dry or winter season and the pre-monsoon or summer season. The monsoon season extends from May to October and is warm and humid. During this period, this locality receives about 88% of the total annual rainfall. The dry season extends from November to February and has the lowest temperature and humidity of the year. The pre-monsoon season extends from March to May and has the highest temperature and evaporation of the year. Field preparation Indigenous organic amendments such as rice hull (RH), rice straw (RS) and sawdust (SD) were used for the studied soil. The experiment was conducted following completely randomized block design with 3 factors, such as RH, RS and SW having 3 doses (0, 2, 4 t ha-1) of each with 3 replications (considered within the plot) under 2 moisture levels (Field moist: FM and 2-5 cm standing water conditions: SW;). The total number of treatment was 27 (3 RH × 3 RS × 3 SD: for each moisture level). Basal doses of N, P2O5, and K2O were applied at the rates of 120, 60 and 80 kg ha-1 from Urea, TSP and MoP fertilizers, respectively. The whole TSP, MoP and half of the Urea were applied during soil preparation by thorough mixing of the fertilizers with the soil. The remaining Urea was top dressed in two splits, one at active tillering and another at panicle initiation stage of rice. Transplantation Seedlings were collected from the local farmers. Thirty-days-old seedlings of BRRI dhan47 were transplanted at the rate of 3 seedlings per hill. The hill to hill and row to row distances were 18 and 22 cm, respectively. For the proper establishment of the rice seedlings, all plots in the field were irrigated with pond water for two weeks after transplantation and then the moisture levels were maintained by the irrigation of same pond water. In the case of moist condition: 70% water content seemed to be enough for the survival of rice plant and did not allow standing water. But in the case of saturated condition: more than 100% water, i.e. 2-5 cm standing water was maintained throughout the growing period. Intercultural operations were performed as required. Soil analysis The physicochemical characteristics of initial soil were determined by following standard methods. The bulk soil samples were air-dried and crushed to 2 mm before analysis. After treatment with 1 M CH3COONH4 (pH 5.0) and with 30% H2O2 to remove free salts and organic matter, respectively, particle size distribution of the initial soil was determined by the Hydrometer method (Piper, 1966). Soil pH was measured by the soil-water ratio of 1:2.5 (Jackson, 1973). The electrical conductivity was determined at a ratio soil: water = 1:5 (Richards, 1954). Organic matter content was determined (Nelson and Sommers, 1982) by wet combustion with K2Cr2O7. Available N (1.3 M KCl extraction, Jackson, 1973), available P (0.5 M NaHCO3, pH 8.5 extraction, Olsen et al., 1954), available K (Pratt, 1965) and available S (BaCl2 turbidity, Sakai, 1978) were determined. Cation exchange capacity was determined by saturation with 1 M CH3COONH4 (pH 7.0), ethanol washing, NH4+ displacement with acidi?ed 10 % NaCl, and subsequent analysis by steam (Kjeldhal method) distillation (Chapman, 1965). Exchangeable Na+, K+, Ca2+ and Mg2+ were extracted with 1 M CH3COONH4 (pH 7.0) and determined by flame photometry (Na+, K+) and atomic absorption spectrometry (Ca+, Mg+). Plant analysis Plant samples were collected after harvesting the crop at maturity. The plants per plot were cut at the 1 cm above ground level.The N contents were analyzed by the H2SO4 digestion through the micro-Kjeldhal method (Jackson, 1973) and P contents by spectrophotometry (Jackson, 1973); K contents by Gallenkamp flame photometry (Black, 1965). The analysis of variance (ANOVA) of the data and the test of significance of the different treatment means were assessed by Tukey’s Range Test at 5% (p < 0.05) level.
