Abstract/ Executive Summary:

Nitrogen application by the use of LCC, a real time N management, helps to increase grain yield and improves efficiency of N by reducing use. To promote LCC use in farmer's fields and improve N use effenciency, a demonstration trial was carried out at Moison, Kapasia, Gazipur during T Aman 2011 and Boro season 2011-12. In T Aman, BRRI dhan46 and in Boro, BRRI dhan28 was used. Grain yields of T Aman varieties were increased and N use was decreased under LCC-based N management over the farmers’ practice. The average yield increased of BRRI dhan46 was 0.30 t/ha in T Aman season. On an average 11 kg N/ha could be saved by LCC-based N management practice in Aman season over the farmers’ practice. Incase of BRRI dhan28, average yield was increased by 0.23 t/ha. On an average 20.1 kg N/ha could be saved by LCC-based N management practice in Boro season over the farmers’ practice.

Keywords: LCC use, N management, T. Aman, Boro rice

Location: Moison, Kapasia, Gazipur

Start Date: 01-07-2011

End Date: 30-06-2012

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To promote LCC use in farmer's fields and improve N use efficiency.

Methodology:

A demonstration trial for promotion of LCC use was carried out in farmers’ fields at Moison, Kapasia, Gazipur during T Aman 2011 and Boro season 2011-12. In T Aman, BRRI dhan46 and in Boro, BRRI dhan28 was used. The method of N application through use of LCC was as per LCC critical value. The fertilizer rates for T. Aman and Boro was 195-60-100-65 and 260-95-120-112 kg/ha of urea, TSP, MP and gypsum, respectively.

Achievement/Findings:

The increased average yield of BRRI dhan46 was 0.30 t/ha in T. Aman and that was 0.23 t/ha for BRRI dhan28 in Boro season. On an average 11 kg N/ha and 20.10 kg N/ha could be saved by LCC based N management practice in Aman and Boro season, respectively over the farmers’ practice.
