Abstract/ Executive Summary:

The experiment was carried out to find out suitable integrated nutrient management options for growth and higher yield of BRRI dhan69. The treatment consists of T1= Control, T2= BRRI recommended fertilizer dose (N-P-K-S = 117-19-58-15 kg ha-1), T3= Soil Test Basis (STB) (N-P-K-S = 134-5-77-16 kg ha-1), T4= 75% STB, T5= 75% STB + Decomposed poultry litter (DPL) (2.5 t ha-1), T6 = 75% STB + DPL (5 t ha-1), T7= 50% STB + DPL (5 t ha-1) and T8= DPL (5 t ha-1). The experiment was laid out in RCB design with three replications. Results indicated that different integrated nutrient management had the significant effect on plant height, leaf area index (LAI), tillering pattern, productive tiller (%), tiller mortality (%), sterility (%), panicle m-2, grains panicle-1 and grain yield. 75% STB + Decomposed poultry litter (2.5 t ha1) showed highest tiller m-2, panicle m-2, grains panicle-1 and ultimately grain yield. 75% STB + Decomposed poultry litter (2.5 t ha-1) gave 11.4% and 18.8% higher grain yield than BRRI recommended dose and STB, respectively. All the treatments with integrated nutrient management gave the higher yield than STB. Treatment T5 found much beneficial than T3. Even the treatments T4 and T6 can be used in BRRI dhan69 cultivation to get more benefit.

Keywords: Integrated nutrient, Growth and yield, BRRI dhan69

Start Date: 00-00-2015

End Date: 00-00-2016

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Rice

Objectives:

This experiment was conducted to know the effect of integrated nutrients on low inputs rice variety, BRRI dhan69.

Methodology:

Experimental site The experiment was carried out at Agronomy field of Bangladesh Rice Research Institute, Gazipur during the Boro season, 2015-16. The soil of BRRI farm was clay loam under Madhupur tract (AEZ 28). Plant materials and planting method Planting crop was BRRI dhan69. Forty-day-old seedling was transplanted using 1 seedling per hill at a spacing of 20 × 20 cm on 19th January, 2016. Experimental design and application of manures and fertilizers The experiment was laid out in RCB design with three replications. The treatments were; T1= Control, T2= BRRI recommended fertilizer dose (N-P-K-S = 117-19-58-15 kg ha-1), T3= Soil Test Basis (STB) (N-P-K-S = 134-5-77-16 kg ha-1), T4= 75% STB, T5= 75% STB + Decomposed poultry litter (DPL) (2.5 t ha-1), T6 = 75% STB + DPL (5 t ha-1), T7= 50% STB + DPL (5 t ha-1) and T8= DPL (5 t ha-1). The full doses of PKS and poultry litter were applied during final land preparation and N was top dressed at 15, 30 and 45 DAT.

Data collection procedure and formulas Tiller number was counted from 40 DAT and continued up to maturity at 15 days interval. Twelve hills from each plot were counted for tillering pattern. Productive tiller (%) and tiller mortality (%) was calculated by using following formulas.

Leaf area index (LAI) was taken at heading stage from one representative hill (selected from average of twelve hills). Plant height was measured from the base of the plant to tip of the panicle. At maturity, a 5 m² area was harvested for grain yield and adjusted to 14% moisture content.

Statistical analysis The data were statistically analyzed using Statistics 10 analytical software. The least significant difference (LSD) at 5% probability was used to compare means of the treatments.

Achievement/Findings:

All the treatments with integrated nutrient showed better performance on the growth and yield of BRRI dhan69 than STB. Even the yield of BRRI dhan69 was higher in T4 (75% of STB) than T3 (STB). From economic and soil health point of view, treatment T5 (75% STB + 2.5 t ha-1 Decomposed poultry litter), is better option for achieving higher yield of BRRI dhan69.
