Experimental site and design: The experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during the rabi (winter) season of 2018-2019 to observe the combined effect of seed priming and planting method on soil salinity and yield of sunflower. The soil belonged to the AEZ-11 and AEZ-13. The land topography was medium low. The soil of the experimental field is clay loam in texture with pH 6.85. There were seven treatment combinations in two factorial RCBD approach with three replications in where factor A was Seed priming considering 4 levels viz. No priming, Hydro–priming for 24 hours, Hydro–priming for 48 hours and Halo–priming for 48 hours (1% NaCl solution).On the other hand, factor B was Planting method and depth considering 3 levels viz. Dibbling (1-5 cm), Reduce tillage (6-10 cm), Conventional Tillage (12-15 cm). Physical Properties of Soil: In order to investigate the physical and chemical properties of various parts of the lands, nine random samples from each replicate were taken by the Auger of 0-15 cm depth and then transported to the laboratory for further analysis. To obtain soil weighted moisture content, the amount of 10 g of soil was poured into metal cans and was placed in the oven for 24 hours at a temperature of 110 °C. Once cooled, the moisture content was calculated based on the oven-dried soil. Particle size distribution was done by hydrometer method and the textural class was determined using the USDA textural triangle. The measurement of soil bulk density (g cm3), soil sample were randomly taken at a depth of 0-15 cm, from the main test plot. The diameter of core sampler was measured with venire caliper. The samples were dried in a hot air oven at 105 °C and dry weight of soil sample was recorded. The bulk density of soil was determined by using the using the RNAM (1995) formula. Cylinder method was exercised to determine soil porosity in the samples (Blake and Hartch, 1986). Soil porosity in each sample was calculated by the following equation: Soil Porosity = [1-(bulk density/particle density)]*100. Bulk density (g cm3) was lowest in dibbling which was statistically identical with Conventional Tillage and Reduced tillage but significantly lower than the MT. Lowest particle density (g cm-3) was obtained in zero tillage which was significantly lower than the other treatments but statistically similar with the MT. Highest porosity (%) was recorded in ZT which was significantly higher than the all other treatments. Chemical properties of the soil: After following the standard methods, soil samples were analyzed for pH, OM, N, P, K, S, Zn, B, Cu, Fe, Mn, Ca, Mg and Na (Table 2). Soil pH was measured using a glass electrode pH meter (WTW pH 5.22) at a soil-water ratio of 1:2.5 as described by Ghosh, soil organic C was measured by Walkley and Black’s wet oxidation method as described by Jackson et al., 1938 and total N was measured by micro-Kjeldahl method; available P was determined following the Bray and Kurtz method, exchangeable K was determined using NH4OAC extraction method, S was determined by turbidimetric method with the help of a spectrophotometer using a wave length of 420 nm, Ca was determined by complexometric method of titration using Na2-TA as a complexing agent, Mg was determined by using NH4OAC extraction method, available Zn, Cu, Fe, and Mn were determined by using diethylenetriamine pentaacetic acid (DTPA) extraction method, B was determined by spectrophotometry method and Na was determined by flame photometry method. CEC (Cation Exchange Capacity) was measured as the summation of the K, Ca, Mg and Na content. Field measurement of soil Salinity: Soil salinity at different dates was recorded at 09:00-10:30 a.m. every 15 days interval, starting from sowing until harvest. The salinity was measured by EC meter (HANNA: HI 9835). Data were taken at the middle of the plot. Once a week, a calibration for the meter was made by comparing with laboratory data and results have been documented. Tillage implements, Seed sowing & crop management: The conventional tillage was conducted by a power tiller, whereas the Reduce tillage was maintained by PTOS. Dibbling was done by the hand placing of seeds in a hole made at a predetermined spacing and depth. The sunflower variety was BARI Surjamukhi-2. In case of dibbling, seeds were sown on 25 November 2018, while others were done on same date i.e 23 December 2019, with a row to row distance of 50 cm and plant to plant 25 cm. Unit plot size was 13m ´ 10m. Three times irrigation at 30, 50 & 70 days after sowing were applied during the growing period. Weeding was done at 14 days after sowing followed by thinning. Disease and insect pests were always well controlled using suggested applies (BARI, 2014). The crop was harvested at the time of maturity. Seed priming techniques: The following standard priming treatment was adopted in all experiments: a single layer of sunflower seeds was submerged in each priming solution or distilled water, to a depth of 1 cm above the top of the seeds (Wahid et al., 2008). Required number of sunflower seeds was soaked in distilled but cool water for hydro–priming 24 hours and hydro–priming 48 hours while halo–priming 48 hours was done by making 1% NaCl solution at around room temperature as per treatments. The ratio of seed weight to solution volume was 1:5 (g mL-1) The treated seeds were surface-dried under forced air on filter paper to their original moisture 8-10% (on dry weight basis). After that, all the treated seeds were sealed in polyethylene bag and stored in refrigerator at 5oC till further use. Fertilizer application methods: Fertilizers were applied following fertilizer recommendation guide 2012 (BARC, 2012). Full amount of triple super phosphate, muriate of potash, gypsum, zinc oxide, boric acid and half of urea were broadcasted in the experimental plot at the time of seed sowing as per treatment. The rest half of urea was applied in equal amounts at 25 & 50 days after emergence. In case of dibbling treatment, fertilization was done with the help of a small implement known as 'Dibbler'. It was a wooden or iron frame with pegs. The frame was pressed in the field and lifted and then required amount of fertilizer were dropped by hand in each of the hole.
