Abstract/ Executive Summary:

The research work was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2007 to investigate the effect of age and number of separated tiller seedlings hill-1 on the performance of transplant aman rice cv. BRRI dhan41. The experimental treatments included (A) three ages of tiller seedlings viz., 20, 30 and 40 days; (B) four different number of tiller seedlings viz., 1, 2, 3 and 4 tiller seedlings hill^-1. The experiment was laid out in a two-factor randomized complete block design with three replications. Both the age and number of tiller seedlings hill^-1 had significant effect on different yield contributing characters including grain and straw yields. Grain yield was the highest due to highest number of effective tillers hill^-1 and grains panicle^-1 at 20-day old tiller seedlings. Straw yield also was found the highest at 20-day old tiller seedlings due to highest plant height and total tillers hill^-1. The lowest grain and straw yields were observed at 40-day old tiller seedlings. Grain and straw yields were highest when 2 tiller seedlings hill^-1were transplanted. Effective tiller hill^-1, grains panicle^-1, 1000-grain weight, plant height and total tiller hill^-1 were lowest when 1 tiller seedling was transplanted hill^-1. The highest grain yield was obtained from the interaction between 20-day old tiller seedling and 3 tiller seedlings hill^-1. For achieving satisfactory yield 20-day old tiller seedling of BRRI dhan41 may be transplanted with 3 seedlings hill-1 just after recession of flood water

Start Date: 00-07-2007

End Date: 00-12-2007

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

1. To identify the suitable age and optimum number of tiller seedlings hill-1 for obtaining satisfactory yield from BRRI dhan41 grown as a post-flood aman crop.

Methodology:

The research work was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2007 to investigate the effect of age and number of tiller seedlings hill^-1 on the performance of transplant aman rice cv. BRRI dhan41. Geographically the experiment site is located at 24.75⁰N latitude and 90.50⁰E longitude at a mean elevation of 18 m above the sea level. It belongs to the Old Brahmaputra Floodplain Agro-Ecolocial Zone (AEZ-9). Which falls into the non-calcareous dark grey floodplain soil. The experimental treatments included (A) three ages of tiller seedlings viz., 20, 30 and 40-day and (B) four levels of number of tiller seedlings hill^-1 viz., 1, 2, 3 and 4 tiller seedlings hill^-1. The experiment was laid out in a randomized complete block design with three replications. The unit plot size was 5m² (2.5 m x 2.0 m) and the space between blocks and between plots were 1.0 m and 0.75 m, respectively. The land was fertilized with urea, triple super phosphate (TSP), muriate of potash (MP), gypsum and zinc sulphate @ 150, 100, 70, 60, 10 kg ha^-1, respectively. The entire amount of TSP, MP, gypsum and zinc sulphate was applied at final land preparation. Urea was top dressed in three equal installments at 15 days after transplanting, tillering stage and panicle initiation stage. Tillers were separated at 20, 30 and 40 days after transplanting from a previously transplanted rice crop and then transplanted in the main field according to experimental treatments on 11 September, 20 September and 30 September, 2007. All management practices were done in proper time. Five hills (excluding border hills) were randomly selected and tagged and uprooted from each plot prior to harvest for collecting data on different crop characters. After sampling, the whole plot was harvested on 15 December 2007. The data on different agronomic characters were recorded from the randomly selected hills in each plot and those on grain and straw yields were recorded from the central 1m² areas of the plot. Data were analyzed using the “Analysis of variance” technique and mean differences were recognized by Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Tiller separation followed by transplanting can be practiced as a promising technology in flood prone areas of Bangladesh to recover the yield loss of transplant aman rice to some extent as a crop rehabilitation measure. For achieving higher yield 20-day old tiller seedling of BRRI dhan41 may be transplanted with 2-4 seedlings hill-1 just after recession of flood water.
