The research work was carried out at the net house of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh. The experimental site is located at 240 N latitude and 940 E longitude of 18 meters high from the sea level. The experimental site belongs to the non-calcareous dark grey flood plain soil under the agro-ecological region of the Old Brahmaputra Floodplain, AEZ 9. The soil was collected within 6 cm from the top of the soil The experimental soil was loamy in texture having a soil pH value of 6.43, moderate in organic matter content. After collection, the soil was sun-dried and loosened and all the inert matter was removed. After that, the Chari (concrete pots) was filled with the soil. The climate of the experimental area is under the sub-tropical climate which is characterized by high temperature, high humidity, and heavy precipitation with an occasional gusty wind from April to September and scanty rainfall associated with moderately low temperature during October to March. Weather data of the experimental site during the period (July to December) have been presented. Treatment includes five organic amendments namely compost @ 10 t ha-1 (A1), cow dung @ 10 t ha-1 (A2), green manure @ 10 t ha-1 (A3), poultry manure @ 10 t ha-1 (A4), no organic amendment (A5). Three-level of salinity were used viz. no salinity (S1), salinity level 25 mM (S2), and salinity level 50 mM (S3). The experiment was conducted in Chari (concrete pots). The radius of each Chari was 30 cm and its area was 2463.02 cm2. The experiment was laid out in a completely randomized design (CRD) with three replications. The total number of Chari was 45 (5×3×3). Considerable spacing was maintained among the Chari for the convenience of cultural operations. The variety used for the experiment was BRRI dhan41. It was developed by the Bangladesh Rice Research Institute (BRRI) from the cross between BR23 and BR1185-2B-16-1. It was released in 2003 as transplanted Aman rice and named BRRI dhan41. Its original breeding line name is BR5828-11-1-4. It is photosensitive, salt-tolerant, tall, bold grain type rice. This variety can tolerate 8-10 dSm-1 salinity when they are tender and 6-8 dSm-1 salinity in the rest of the living period. The cultivar BRRI dhan41 matures within 150 days after transplanting. It attains a plant height of about 115 cm. The average yield of BRRI dhan41 is 4.5 t ha-1. Seeds were collected from Bangladesh Rice Research Institute (BRRI), Joydevpur, Gazipur. Seeds of BRRI dhan41 were dipped into water in buckets for 24 hours and then taken out of the water and packed in gunny bags for sprouting. The seeds sprouted after 72 hours of steeping. Seedling nursery for the variety was prepared by puddling the soil. Sprouted seeds of the variety were sown on 29 June 2013 and after sowing the seeds, proper care was taken for normal growth and development of the seedlings in the nursery bed. All weeds and stubble were removed and beds were properly leveled. Chari was selected for the experiment to check the loss of saline water. The size of the Chari was 30 cm in diameter on top and 40cm in height. The total number of Chari was 45 (5×3×3). Then each of the Chari was filled with the collected soil and fertilized with recommended dose for the variety BRRI dhan41 considering the soil type used for the experiment. Each chair was filled up with 22 kg soil and leveled well. The applied fertilizer dose of the variety BRRI dhan41 were urea 150 kg ha-1, TSP 90 kg ha-1, MoP 70kg ha-1, gypsum 60 kg ha-1, and zinc Sulphate (ZnSO4) 12 kg ha-1. The total amount of TSP, MoP, gypsum, and zinc Sulphate (ZnSO4) and one-third of the Urea were applied during the final Chari preparation, and the rest of the Urea was top dressed in two equal splits. One at 20 days after transplanting (DAT) and another one at 40 days after transplanting (DAT). All the fertilizers were incorporated in the topmost soil within 6 inches of the Chari soil. Organic amendments viz., control, compost, cow dung, green manure (Sesbania rostrata), and poultry manure were applied @ 10 t ha-1 in the respective Chari. The organic amendments were applied during Chari preparation for well decomposing. Nursery beds were made wet by application of water both in the morning and the evening in the previous day before uprooting the seedlings. Without causing any major injury to the roots, the seedlings were uprooted. Seedlings were uprooted from the nursery bed on 1 August 2013. Transplanting was done on 1 August 2013. Three seedlings were transplanted in each hill and six hills were transplanted in each chair. Transplanting was done as early as possible after uprooting. Seedlings of some hills died off and those were replaced by gap-filling (after 1 week of transplanting) with the seedlings from the same sources and same-aged. The Charis were kept weed-free (by hand weeding) from the very beginning of transplanting up to the harvesting of the crop. Plants were infested with Rice stem borers which were successfully controlled by the application of Basudin 10G @ 20kg ha-1. The roof of the net house was covered with a thin polythene sheet to protect the Charis from rainwater. Commercial salt (NaCl) was used for developing salinity. For treatments of S1, S2, and S3, 0g, 52.85g, and 105.89g of salts were added respectively in the respective Chari. These amounts of salts were dissolved in 1000 ml of water and the solutions were then poured uniformly into the Chari at tillering stage. The crop was harvested Chari-wise at full maturity on 1 December 2013. After harvesting, the crop of each Chari was bundled separately and tagged properly. The bundles were sun-dried properly before recording data on various plant characteristics and yields. Data were recorded at harvest for plant height at harvest (cm), number of total tillers hill-1, number of effective tillers hill-1, number of non-effective tillers hill-1, number of panicles hill-1, panicle length (cm), number of total spikelets panicle-1, number of grains panicle-1, number of sterile spikelets panicle-1, the weight of 1000 grains (g), grain yield (t ha-1), straw yield (t ha-1), biological yield (t ha-1) and harvest index (%). The data were recorded as per the procedure described elsewhere. The recorded data were tabulated and the “Analysis of Variance” was done using the computer package MSTATC program. The means were evaluated with Duncan’s Multiple Range Test.
