Abstract/ Executive Summary:

A field experiment was conducted in the char areas of Young Brahmaputra Jamuna Fioodplain soil under AEZ-8 at Naobhanga char Jamalpur during 2013-2014 to find out the response of groundnut to chemical and bio fertilizers having six treatments replicated thrice following RCB design where the tested variety was BARl Chinabadam 8.Treatments were T₁=FRG 2012 (N₆₀P₅₀K₈₀ S₅₀Zn₃B₂ MO_0.6 kg/ha), T₂=PKSZnBMo kg/ha + bio fertilizer, T₃= PKSZnBMo kg/ha, T₄=N kg/ha, T₅=bio fertilizer and T₆ = Control (native nutrients).Groundnut (var.BARl Chinabadam 8) was found responsive to added fertilizers. T₁ and T₂ treatment were statistically similar and gave the highest pod yield in compare to others where the lowest pod yield found in control. T₂(PKSZnBMo kg/ha + bio fertilizer) treatment can be considered as the optimum and economic dose for groundnut production at char areas of Young Brahmaputra-Jamuna Floodplain soil.

Keywords: Groundnut, Chemical fertilizers, Bio fertilizers, Soil fertility

Location: Bangladesh Agricultural Research Institute (BARI), Gazipur-1701, Bangladesh

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Crop-Soil-Water Management

Commodity: Ground nut, Soil fertility

Objectives:

To find out optimum rates of chemical fertilizers along with bio fertilizer for groundnut production in char areas.

Methodology:

The experiment was conducted in the char areas of Brahmaputra river located at char Naobhanga, Jamalpur Sadar. Seeds were sown on 15 December 2013. The experiment was designed in Randomized Complete Block Design having three replications in each treatment. BARI Chinabadam 8 variety was used as the variety of ground nut. Unit plot size was 4 m x 3 m. There were six treatment combinations comprising T₁= N₆₀P₅₀K₈₀S₅₀Zn₃B₂MO_0.6 kg/ha (FRG-2012), T₂= PKSZnBMo kg/ha + Biofertilizer, T₃= PKSZnBMo kg/ha, T₄= N kg/ha, T₅= N kg/ha and T₆= Control (native nutrients). Bradyrhizobium was used as bio-fertilizer, During the time of experiment conduction, irrigation, weeding and other interculture operations were done carefully. Plant height, number of branches per plants, Number of effective pods per plants, Number of non effective pods per plants, 100 seed weight and yield(Kg/ha)were recorded. The plants were harvested on 05 June 2014. All data were analyzed statistically.

Achievement/Findings:

From the first year experiment, it may be suggested that P₅₀K₈₀S₅₀Zn₃B₂ MO_0.6 kg/ha + 1.5 kg/ha bio fertilizer can be considered as suitable for the highest yield of groundnut production. The experiment will be repeated for the confirmation of the result.
