Abstract/ Executive Summary:

A field experiment was carried out at Oilseed Research Centre, Bangladesh Agricultural Research Institute, Gazipur, during the rabi season of 2007-08 and 2008-09 to find out optimum and economical variable fertilizer dose of mustard variety BARI Sarisha -15. The experiment was conducted in 4m x 3m size plots in a randomized complete block design (RCBD) with three replication. Mustard variety BARI sharisa-15 and five treatments including one control treatment comprising different doses of chemical fertilizers were used in the study. The treatments were T₁ (N₁₂₀ P₃₅ K₅₀ S₂₅Zn₄B₂), T₂ (N₉₀ P₃₀ K₄₀ S₂₀ Zn₃ B_1.5), T₃ (N₆₀ P₂₅ K₃₀ S₁₅ Zn₂ B₁), T₄ (N₃₀ P₂₀ K₂₀ S₁₀ Zn₁ B_0.5 kg/ha) and T₅ native nutrient (control). Results showed that treatment T₂ (N₉₀ P₃₀K₄₀ S₂₀ Zn₃ B_1.5kg/ha) were optimum for mustard variety BARI Sarisha -15 production both 2007- 08 and 2008-2009 which produced yield 1750kg/ha and 1725kg/ha. The highest net return Tk.29911/ha, Tk 29411/ha. and benefit cost ratio 5.30 and 5.23 were obtained from the same treatment.

Commodity: Mustard

Objectives:

1. The present study was therefore, under taken to know the optimum doses of N, P, K, S, Z and B.

Methodology:

The experiment was conducted at Oilseed Research Centre, Bangladesh Agricultural Research Institute, Gazipur, during the rabi season of 2007-08 and 2008- 09. It was laid out in randomized complete block design (RCBD) with three replications. The five fertilizer doses are T₁ = 120: 35: 50: 25: 4: 2, T₂ = 90: 30: 40: 20: 3: 1.5, T₃ = 60: 25: 30: 15: 2: 1.0, T₄ = 30: 20: 20: 10: 1.0: 0.5 N P K S Zn B kg/ha and T₅ = Native nutrient. Mustard variety BARI Sarisha - 15 was used for the experiment. The unit plot size was 4 m X 3 m. Seeds were sown on November 5, 2007 and 2008 in continuous and row was 30 cm apart from each. The seedlings were thinned after a few days of germination 5 cm apart. Half of the urea and all other fertilizers were applied during final land preparation. The rest of the urea was applied at the initial stage of flowering. During land preparation, cow-dung was applied at 10 ton/ha. All intercultural operations such as pest and disease management, irrigation was given towice, earthing up, weeding and mulching, etc. were done timely to raise the crop uniformly. Data were taken on days to maturity, plant height, no. of branches/plant, no. of siliqua/plant, no. of seeds/siliqua, 1000 seed wt, stover yield and seed yield/plot. The plot yield was converted into hectare. From each plot 10 randomly selected plants were sampled for data collection. The Recorded data were compiled and analyzed statistically and means were separated by Duncan’s Multiple Range Test (DMRT). To find out the difference among the treatments. Benefit cost ratios (BCR) of different treatments were also calculated.
