Abstract/ Executive Summary:

The study was conducted at BRRI, Gazipur. The following varieties and other parameters were considered for this study photo sensitive: BR5, BR22 & BR23, Photo insensitive: Short duration: BRRI dhan31, BRRI dhan32 & BRRI dhan33 and Long duration: BR3, BR14 & BRRI dhan29. Seedling age was 30 days. Irrespective of varieties, seedling height and dry matter content of the seedling increased with the increase of storage duration. Among the varieties, BR3 produced the highest dry matter (>0.6 g/seedling) followed by BR5, BR22 and BR23 (>.04 g/seedling). The lowest dry matter production was found in BRRI dhan31. There was no significant difference found in percent survival of the seedling at post establishment period although the dry content of different varieties was different. Generally the survival percentage mostly depends on dry matter content of the seedling. The Growth duration varied among the storage duration and seedling age in case of the photo-insensitive variety but significant difference was not found in case of the photo-insensitive variety. Photo-sensitive varieties performed better than photo-insensitive varieties. The significant yield reduction due to different storage duration was not found in photo-sensitive varieties. In case of BR22, the grain yield was 5.23 t/ha at normal transplanting while it was 5 t/ha when the seedling 21 days. But significant reduction due to storage duration was found in photo-insensitive varieties. In case of BR3, 4.85 t/ha grain yield was found in normal planting or 0 days storage duration while more than 1 t/ha grain yield reduced when the seedling stored up to 21 days. Similar results was observed in case of photo-sensitive varieties. The yield component data also showed the similar trend.

Start Date: 00-07-2004

End Date: 00-06-2005

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To investigate the interaction between variety and storage duration.
To find out the suitable variety for double transplanting.

Methodology:

The study was conducted at BRRI, Gazipur. The following varieties and other parameters were considered for this study photo sensitive: BR5, BR22 & BR23 Photo insensitive: Short duration: BRRI dhan31, BRRI dhan32 & BRRI dhan33 Long duration: BR3, BR14 & BRRI dhan29. Seedling age: 30 days old seedling. Seedling transplanting time: 0,7,14, and 21 days after 1st transplanting. Design: Split-split plot where variety in main plot, seedling age in dub plot and transplanting time in sub-sub plot.

Achievement/Findings:

Photo sensitive variety was more suitable for double transplanting than photo-insensitive variety. Among the Photosensitive varieties, BR22 was more suitable than the other varieties. Among the photosensitive varieties, the short duration variety is more suitable for double transplanting than the long duration. (ii)The seedling could be stored up to 21 days for photosensitive variety while 14 days for short duration and 7 days for long duration photo-insensitive variety respectively.
