Abstract/ Executive Summary:

Field experiments with seven rice cultivars viz. Sonarbangla (SB) -I, 2, 3, 4, BRRI dhan32, 33 and BR- II were conducted at the Farming System Research and Development site, (FSRO) Syedpur Rangpur, Nilphamari and Lalmonirhat Multi Location Test (MLT) Site during Kharif-II, 1999. Considering all the characters studied SB-3 was found to be suitable hybrid variety at FSRO site, Syedpur, Rangpur, Nilphamari MLT site and SB-3 and SB-2 were found to be suitable hybrid varieties at Lalmonirhat. MLT site.

Keywords: Hybrid rice, Food production, Hybrid variety

Location: field at FSRD site, Syedpur; Nilphamari and Lalmonirhat MLT sites

Start Date: 00-00-1999

End Date: 00-00-1999

Program Area: Variety and Species

Commodity: Rice

Objectives:

To find out best hybrid variety (s).

Methodology:

There were three sets of experiment placed in the farmers' field at FSRD site, Syedpur; Lalmonirhat and Nilphamari, MLT sites, respectively during Kharif-II 1999. The experiment was laid out in Randomize Complete Block Design with four dispersed replication each site. The trial was conducted with Hybrid varieties viz. Sonarbangla-l (SB-l), Sonarbangla-2 (SB-2), Sonarbangla-3 (SB-3) & Sonarbangla-4 (SBA), and HYV viz. BRRI dhan32, BRRI dhan33 and BR-ll as check. Unit plot size was 4.7 m x 19 m. Each Seedbeds were prepared measuring 5 m x 1 m. During seedbed preparation fertilizers were applied at the rate of Urea 225 g, TSP 105 g, MP 85 g and cowdung 100 kg for each seed bed. Seedbed was top dressed with 225 gm of urea 7-8 days before transplanting. Seedbed was kept moist all the time. Seedlings of 22-25 days old were transplanted in the main field. Transplanting was accomplished within 6-10 August 1999 with a spacing of 15 cm x 20 cm each site. Basal dose of fertilizers were applied at the rate of Urea 90 kg, TSP 80 kg, MP 64 kg, Gypsum 110 kg, ZnS0₄ 12 kg, Boron 15 kg per hectare. Cowdung was applied at the rate of 12 tons/ha. Two top dressing of urea was given at the rate of 90 kg/ha. First top dressing was applied on the 4^th week of August 1999 and second top dress was given on the third week of September 1999. Furadan was applied twice, first on third week of August 1999 and second on third week of September 1999. Irrigation was given as and when required. Data on the yield and yield related characters were recorded and analyzed, using the "Analysis of variance" technique with the help of computer package MSTAT. Duncan Multiple Range Test adjudged the mean differences.

Achievement/Findings:

Considering all the characters studied SB-3 was found to be suitable hybrid variety at FSRD site, Syedpur, Rangpur and Nilphamari MLT site and SB-3 and SB-2 was found to be suitable hybrid varieties at Lalmonirhat, MLT site. hybrid variety SB-3 did not perform well compared to the check varieties of this location. Therefore hybrid rice can play a vital role in increasing the food production of our country. Keeping this view in mind a trial was taken to find out best hybrid variety.
