Abstract/ Executive Summary:

The was undertaken to determine the optimum planting time for escaping salinity at at the southern saline prone area of Bangladesh in Boro season. The varieties: 1. BRRI dhan28; 2. BRRI dhan47 and 3. BRRI dhan61 and planting time were 4(from 12 January to 25 February). The experimental area was laid out in design RCB with three replications and was transplanted at 20- × 20 cm spacing. The grain yield of varieties gradually decreased with the advancement of planting dates in Boro season. The variety BRRI dhan28 produced higher grain yield over other two variety BRRI dhan47 and BRRI dhan61 irrespective of planting dates on 12 January and then decreased. BRRI dhan47 gave higher grain yield over other two varieties irrespective of planting dates from 28 January to 25 February due to increasing salinity.

Start Date: 01-11-2013

End Date: 31-06-2014

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

The experiment was conducted at Kalapara, Patuakhali to determine the optimum planting time for escaping salinity at at the southern saline prone area of Bangladesh in Boro season.

Methodology:

The varieties: 1. BRRI dhan28; 2. BRRI dhan47 and 3. BRRI dhan61 and planting time were 4(from 12 January to 25 February). The experimental area was laid out in design RCB with three replications and was transplanted at 20- × 20 cm spacing. The unit plot size was 5 × 4 m². BRRI Recommended fertilizer doses were; Urea at 284 kg ha^-1, TSP 82 kg ha^-1, MOP 82 kg ha^-1, Gypsum 63 kg ha^-1, ZnSO₄ 7 kg ha^-1. The full dose of TSP, MOP, Gypsum and ZnSO₄ were applied during final land preparation. Urea was top dressed at 20 & 40 DAT. Irrigation water, insect and weed control were done as and when necessary. Data on plant height, grains/panicle, sterility (%) and grain yield were recorded at harvest.

Total Budget (Tk.) : 20000/-

Achievement/Findings:

BRRI dhan28 produced higher grain yield over other two variety BRRI dhan47 and BRRI dhan61 at early transplanting (planting dates on 12 January). BRRI dhan47 gave higher grain yield over other two varieties at late transplanting (planting dates 28 January to 25 February) due to increasing salinity.
