Abstract/ Executive Summary:

Poultry manure 2 t/ha along integrated plant nutrient system (IPNS) based NPKS (100 kg N, 0 kg P and S, and 30 kg K/ha) gave 5.64 t/ha compared to 5.40 t/ha with soil test based (STB) chemical fertilizer (140 kg N, 30 kg P, 70 kg K and 20 kg S/ha) application in Boro (var. BRRI dhan29). Heavy metals (Cd, Pb, As, Cr and Ni) in the poultry manure were within the range of the allowable limit.

Keywords: Poultry manure, IPNS, STB, BRRI dhan29, Heavy metal, Rice

Location: BRRI experimental farm, Gazipur

Start Date: 01-07-2007

End Date: 30-06-2008

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

to determine the doses of poultry manure (PM) with chemical fertilizers on the basis of IPNS concept
to determine the level of PM addition with 50% STB dose

Methodology:

The field experiments were conducted at the BRRI experimental farm, Gazipur during the period from Boro2007 to T.Aman2009. The soil of the experimental field was clay loam in texture having pH 6.84, organic matter 2.42%, total N 0.14%, available P 5.77 ppm, exchangeable K 0.14 meq/100g soil, available S 6.6 ppm and available Zn 2.8 ppm. The following treatments viz; T1 = Absolute control, T2 = PM @ 1 t/ha + IPNS based STB dose, T3 = PM @ 2 t/ha + IPNS based STB dose T4 = PM @ 3 t/ha + IPNS based STB dose, T5 = PM @ 1 t/ha + 50% STB dose, T6 = PM @ 2 t/ha + 50% STB dose, T7= PM @ 3 t/ha + 50% STB dose and T8= 100% STB dose were tested in the experiment. Thirty-day decomposed (oven dry based) poultry manure, one-third of N and the whole amount of PKS were applied at final land preparation as per treatment requirement in Boro season. The remaining two-third N was applied in two equal installments at 25-30 days after transplanting and at 7 days before panicle initiation stage. Poultry manure was applied in Boro and the residual effect was observed in T.Aman. The test variety in Boro and T. Aman was BRRI dhan29 and BRRI dhan31, respectively. The Experimental design was RCB with 3 replications. The individual plot size was 4m x 4m. The crops were harvested at maturity from 5 m2 areas and then the grain yields were recorded at 14 % moisture and straw yields at oven dry basis. Nitrogen content from plant samples were determined by micro Kjeldahl method. Phosphorus, potassium, sulfur and zinc content of these samples were determined by using standard laboratory analytical procedure.
