Abstract/ Executive Summary:

An experiment was conducted to study the performance of BRRI dhan57 regarding to growth, yield and yield contributing characters under the AEZ-28. It was found that all the traits were statistically significant due to Phosphorus and Sulphur. All the studied characters were also significantly affected by the interaction effect between Phosphorus and Sulphur fertilizers whereas interactions affect between 40 kg P and 20 kg S ha^-1 perform the best comparatively than that of other interactions. The interaction of 40 kg P + 20 kg S ha^-1 also produced maximum effective and minimum non effective tillers hill^-1, longest panicle, maximum filled and minimum unfilled grains panicle^-1, highest weight of 1000 grain, higher yield of grain, straw and biological and higher HI whereas they were statistically significant among other interactions in respect of all the above traits. Nutrient content and uptake of N, P, K and S by grain and straw were also significantly affected by the singly or interaction effect of P and S in this study.

Keywords: Phosphorus, Sulphur, Growth and yield, BRRI dhan57

Location: Shere-e-Bangla Agricultural University Research Farm

Start Date: 00-07-2013

End Date: 00-12-2013

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1.To examine the differences of morpho-physilogy and grain production of BRRI dhans57 as influence by the various doses of P and S

2.To find out the appropriate doses of P and S regarding to proper growth and higher production of BRRI dhan57

3.To select the most advantageous treatment combination of P and S fertilizers concerning to growth and yield of BRRI dhan57

Methodology:

An experiment was conducted to study the performance of BRRI dhan57 regarding to growth, yield and yield contributing characters under the AEZ-28 during July to December 2013.

Experimental treatments

Different doses of Phosphorus (P) and Sulphur (S) were applied in experimental field as experimental treatments where K and P were used as factor A and B, respectively. From the above experimental treatment it will be mentioned as are as follows

Factor A: Four doses of Phosphorous (P)

P₀ : 0 kg P ha^-1 (control)

P₁ : 20 kg P ha^-1

P₂ : 40 kg P ha^-1

P₃ : 60 kg P ha^-1

Factor B:

S₀ : 0 kg S ha^-1 (control)

S₁ : 10 kg S ha^-1

S₂ : 20 kg S ha^-1

S₃ : 30 kg S ha^_-1

So, the treatments combinations were as follows

P₀S₀: 0 kg P ha^-1 x 0 kg S ha^-1 (control)

P₀S₀: 0 kg P ha^-1 x 0 kg S ha^-1

P₀S₁: 0 kg P ha^-1 x 10 kg S ha^-1

P₀S₂: 0 kg P ha^-1 x 20 kg S ha^-1

P₀S₃: 0 kg P ha^-1 x 30 kg S ha^-1

P₁S₀: 20 kg P ha^-1 x 0 kg S ha^-1

P₁S₁: 20 kg P ha^-1 x 10 kg S ha^-1

P₁S₂: 20 kg P ha^-1 x 20 kg S ha^-1

P₁S₃: 20 kg P ha^-1 x 30 kg S ha^-1

P₂S₀: 40 kg P ha^-1 x 0 kg S ha^-1

P₂S₁: 40 kg P ha^-1 x 10 kg S ha^-1

P₂S₂: 40 kg P ha^-1 x 20 kg S ha^-1

P₂S₃: 40 kg P ha^-1 x 30 kg S ha^-1

P₃S₀: 60 kg P ha^-1 x 0 kg S ha^-1

P₃S₁: 60 kg P ha^-1 x 10 kg S ha^-1

P₃S₂: 60 kg P ha^-1 x 20 kg S ha^-1

P₃S₃: 60 kg P ha^-1 x 30 kg S ha^-1

Achievement/Findings:

The use of 40 kg P ha^-1 or 20 kg S ha^-1 as singly or their interaction would be highly effective for higher production of BRRI dhan 57 under the regional condition of AEZ-28.
