The experiment was conducted at the research farm of Regional Laboratory of Soil Resource Development Institute (SRDI), Gabua, Noakhali in the southern part of Bangladesh during November 2012 to April 2013. The experimental field was man-made high land belonging to Chandragonj soil group of Non-calcareous Gray Floodplain Soil type under agro-ecological zone of Lower Meghna River Flood plain (AEZ-17). Soils of the experiment site was silty clay loam in the upper 15 cm. Seeds of BARIFallon-1 were collected from On-farm Research Division (OFRD), Bangladesh Agricultural Research Institute (BARI), Noakhali. Inoculums of biofertilizer were collected from Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh. Six nutrient management practices were used as treatments. First treatment was only chemical fertilizer dose approach, where nutrients requirement was assessed on soil test value basis. Second treatment was combined dose of chemical fertilizer and organic manure (cow dung). Rate of cow dung was adjusted to 5 t ha-1. At first the amount of nutrients supplied from cow dung was calculated and then it was deducted from the total requirements of nutrients. The rest amount of nutrients was supplied through chemical fertilizers. Third treatment was combined dose of chemical fertilizer and green manure crop (dhaincha). For this purpose dhaincha (Sesbania esculent L.) was grown in three experiment plots and when their height became 12 cm, whole bodies were incorporated into soil. Biomass was yielded to 0.60 t ha-1. It was calculated according to Meelu et al.(1994) where they stated that dhaincha (Sesbaniasp.) can yield 3 to 5 t ha-1dry biomass in 50 -60 days at height of 90 to 110 cm.According to FRG (2005), 1.0 t dhaincha materials supply 2.5 kg N, 0.3 kg P and 2.0 kg K. Thus, 0.6 ton materials was supposed to supply 1.5 kg N, 0.18 kg P and 1.2 kg K ha-1, respectively. The amount of nutrients was deducted from the total requirements. The rest amounts of nutrients were supplied through chemical fertilizers. Fourth treatment was combined dose of chemical fertilizer and bio-fertilizer. Seeds and inoculums were treated with molasses and then sowed in the field. Fifth treatment was farmer’s practice. Three experimental plots were given to a farmer, where he applied only urea @ 0.21 t ha-1. Sixth treatment was control, where no chemical fertilizer or manure was applied. Before ploughing composite soil samples were collected from the field and analyzed at Regional Laboratory of Soil Resource Development Institute (SRDI), Noakhali. Recommended dose of fertilizer, biomass addition from dhaincha and inoculums of biofertilizer were calculated according to Fertilizer Recommendation Guide, 2005on integrated plant nutrient system (IPNS). Fertilizer doses (kg ha-1) of T1, T2, T3, T4, T5 and T6 were: (i) urea 34 kg, TSP 84 kg, MoP 13 kg, (ii) TSP 58 kg and cow dung 5 t ha-1, (iii) urea 31 kg, TSP 83 kg, 10 kg MoP and Dhaincha 0.6 t ha-1, (iv) TSP84 kg, TSP 13 kg and biofertilizer inoculums @ 1.6 kg, (v) urea 208 kg, and (vi) no chemical fertilizer or manure. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The experimental field was first opened on November 2012 with a power tiller. The land was ploughed and cross ploughed 4 times followed by laddering. Field was then divided into three blocks. Each block was divided into six plots. Each block represents a replication and each plot represents an experimental plot. The size of the unit plot was 3 m × 4 m. The blocks were 1 m apart and distance between unit plots was 0.5 m. The borders were 1 m wide and total area of the experimental field was 65 m × 15 m. Rows of plots were oriented in north-south directions.
