A field study was carried out at the research farm of Charfasson Govt. College, Bhola, Bangladesh during rabi season in 2015-2016. Soil samples (0- 15 cm depth) were collected from the research farm. The sample was air-dried, ground and sieved through 3 mm sieve for chemical analysis and 2 mm sieve for physical analysis and kept in polyethylene bags. The soil had found pH of 8.36 (1: 2.5 w/v H2O), organic carbon 0.63% (Wet oxidation method, Walkley and Black, 1934), available nitrogen 0.24% (Kjeldahl extraction, Marr and Cresser, 1983), available phosphorus 0.06% (Jackson, 1958), available potassium 1.23% (Pratt, 1965), available sulfur 0.15% (Bardsley and Lancaster, 1965), sand 12.3%, silt 51.34% and clay 36.36%, textural class- silty clay loam (Bouyoucos, 1962), the maximum water retentive capacity was 37%, respectively. Seeds were collected from BADC, Barishal. The variety of seed was BARI-2 (Keroni-2). The experiment was laid out in a randomized complete block design (RCBD) having sixteen treatments with three replications. The unit plot size was 3.0 m x 2.0 m and total plots were 48. Treatments were T1 Control (-RB and -NPK), T2: 2.5 t RB ha-1, T3: 5.0 t RB ha-1, T4: 7.5 t RB ha-1, T5: N40P30K50 kg ha- 1, T6: N80P60K100 kg ha-1, T7: N120P90K150 kg ha-1, T8: 2.5 t RB ha-1 + N40P30K50 kg ha-1, T9: 2.5 t RB ha-1 + N80P60K100 kg ha-1, T10: 2.5 t RB ha-1 + N120P90K150 kg ha-1, T11: 5.0 t RB ha-1 + N40P30K50 kg ha-1, T12: 5.0 t RB ha-1 + N80P60K100 kg ha-1, T13: 5.0 t RB ha-1 + N120P90K150 kg ha-1, T14: 7.5 t RB ha-1 + N40P30K50 kg ha-1, T15: 7.5 t RB ha-1 + N80P60K100 kg ha-1 and T16: 7.5 t RB ha-1 + N120P90K150 kg ha-1.The doses were selected according to the Fertilizer Recommendation Guide of Bangladesh Agricultural Research Council (BARC, 2012). At the time of initial land preparation, rice bran was applied and at final land preparation, N, P and K were applied as urea, triple super phosphate and muriate of potash, respectively. Seeds were sown on 29 December 2015. Sixty seeds were sown in each plot. Length between row to row was 40 cm and the width between seed to seed was 25 cm. Intercultural practices i.e. weeding, spading, fencing, pesticide etc. were applied as per when needed. Finally, plants were harvested after 90 days of sowing of seeds at the period of maturity. Different organs of sunflower plants viz., stem, root, leaf, petiole, inflorescence and seed were collected and dried in an oven at temperature of 650C. The dry weight of different parameters and seed weights were measured and those were kept in paper bags separately. The uptake of nutrients by different parts of sunflower plant was worked out by multiplying the nutrient concentration and dry matter yield of the plant parts. Estimation of oil content (%) in the seed sample was done by Soxhlet Fat Extraction method evolved by (AOAC, 1990). Seed protein content was calculated by multiplying the N content of seed with a factor of 6.25. Analysis of variance was done with the help of SPSS program and the mean differences among different treatments were evaluated by LSD test at 5% level.
