Abstract/ Executive Summary:

An experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during the rabi season of 2017-2018 to know the effect of different levels of N and foliar application of B on mustard. There were three nitrogen levels (N₁ = 90 kg N ha^-1, N₂ = 120 kg N/ha, N₃= 150 kg N ha^-1) & four foliar applications of boron (B₁ = Foliar application of Boron in pre-flowering stage, B₂ = Foliar application of Boron in flowering stage, B₃ = Foliar application of Boron in grain filling stage), foliar dose of Boron =4 g liter^-1. Seed yield (1.23 t ha^-1) was recorded highest in N₃B₁ which was significantly higher than the rest of the treatments. Higher levels of BCR was recorded in N₃B₁ (1.94) with higher gross margin (Tk. 29750 ha^-1). In coastal area, mustard should be treated with 150 kg N ha^-1 together with foliar application of B in pre-flowering stage to have a better yield with higher economic return.

Keywords: Folier boron application, Mustard, Coastal area

Location: ARS, BARI, Benarpota, Satkhira

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Maize

Objectives:

To know the effect of different levels of N and foliar application of B on mustard.

Methodology:

Experimental site and design: The experiment was conducted at the Agricultural Research Station (ARS), BARI, Benarpota, Satkhira during the rabi season of 2017-2018 to know the effect of different levels of N and foliar application of B on mustard. 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 7.3. There were three nitrogen levels (N₁ = 90 kg N ha^-1, N₂= 120 kg N ha^-1, N₃= 150 kg N ha^-1) &three foliar applications of boron (B₁ = Foliar application of Boron in pre-flowering stage, B₂ = Foliar application of Boron in flowering stage, B₃ = Foliar application of Boron in grain filling stage), foliar dose of Boron = 4 g liter^-1. The crop variety was BARI Mustard-14. The experiment was tested in RCBD (2 factor) with three replications. Unit main plot size was 4.6 × 2.5m and sub-plot size was 1.2m × 2.5m. At every 15 days interval soil salinity (dS m^-1) was measured by EC meter (HANNA: HI 9835). Data on yield and yield components were recorded and analysed statistically using MSTAT-C program. Seed sowing & crop management: The experimental plots were fertilized with 170-85-150 kg ha^-1 TSP, MoP and Gypsum, respectively. All the fertilizers were applied as basal except Urea. Seeds were sown in 28 November, 2017 in row to row distance of 30 cm. Three irrigations were applied during the growing period. Weeding was done at 14 days after sowing followed by thinning to keep plant to plant distance of 10 cm. Disease and insect pests were always well controlled using suggested applies (BARI, 2014). The crop was harvested at the time of maturity.

Achievement/Findings:

In coastal area, mustard should be treated with 150 kg N ha^-1 together with foliar application of B in pre-flowering stage to have a better yield (1.23 t ha^-1) with higher economic return (BCR = 1.94).
