Abstract/ Executive Summary:

The highest yield of 7.37 t/ha was obtained in 1 December sown drum seeding followed by 7.35 t/ha in 30 December transplanting with 15 cm x 15 cm spacing. The lowest yield of 6.55 t/ha was obtained in 30 December transplanting with 20 cm x 20 cm spacing. The interaction effect of planting method and planting time for panicle no/m² was significant. The highest panicle no./m² of 422 was obtained in 1 December sown hand seeding and lowest panicle no/m² of 284 was obtained in 15 December transplanting with 20 cm x 20 cm spacing The effect of establishment method on grain/panicle was significant. The highest grains/panicle of 112 was obtained in transplanting with 20 cm x 15 cm spacing and lowest grains/panicle of 88 was obtained in hand seeding.

Keywords: Drum seeding, Closer spacing, Different planting time

Location: BRRI, Gazipur

Start Date: 01-07-2005

End Date: 30-06-2006

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To increase panicle number in transplanting through closer spacing and compare its performance with drum seeding.

Methodology:

BRRI has recommended drum seeding as a cost saving yield increasing and early maturing rice establishment technique than traditional transplanting. It is claimed that the main reason for yield increase in drum seeding is due to higher number of panicle per unit area. Therefore this experiment was undertaken to increase panicle number in transplanting through closer spacing and compare its performance with drum seeding. Three spacings for transplanting viz. 20 cm x 20 cm (usual spacing), 20 cm x 15 cm (closer spacing), 15 cm x 15 cm (closer spacing) was tested along with drum seeding and hand seeding under two planting times. The experiment was laid out in a factorial RCB design with three replications in BRRI farm. Other management practices are followed as per recommendation.

Achievement/Findings:

The results revealed that there was no significant yield difference among the treatments. However the highest yield of 7.37 t/ha was obtained in 1 December sown drum seeding followed by 7.35 t/ha in 30 December transplanting with 15 cm x 15 cm spacing. The lowest yield of 6.55 t/ha was obtained in 30 December transplanting with 20 cm x 20 cm spacing. The interaction effect of planting method and planting time for panicle no/m² was significant. The highest panicle no./m² of 422 was obtained in 1 December sown hand seeding and lowest panicle no/m² of 284 was obtained in 15 December transplanting with 20 cm x 20 cm spacing The effect of establishment method on grain/panicle was significant. The highest grains/panicle of 112 was obtained in transplanting with 20 cm x 15 cm spacing and lowest grains/panicle of 88 was obtained in hand seeding. The effect on thousand grain weight was insignificant.
