Abstract/ Executive Summary:

Comparatively grain development was found good from Machete 5G herbicide and direct seeding with spacing 25cm × 20cm and also direct seeding with 20cm × 20cm and Machete 5 G herbicide. Grain development was slow in Ronstar 25 EC herbicide and broadcasting method. Regarding yield parameters at harvest, the highest performance seemed to be from direct seeding with spacing 20 cm × 20 cm and Machete 5G herbicide for grain yield (4.04 t ha^-1), straw yield (5.33 t ha^-1).

Keywords: Direct seeding, Herbicides, Binadhan-4

Location: BINA HQ, Mymensingh

End Date: 00-12-2004

Program Area: Crop-Soil-Water Management

Commodity: , Rice

Objectives:

To evaluate the effect of direct seeding with different spacing and herbicides on the growth and yield of transplanted Aman

Methodology:

A field experiment was carried out at the field of the Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh, during the period from August to December 2004 to evaluate the effect of direct seeding with different spacing and herbicides on the growth and yield of transplanted Aman (cv. Binadhan-4). Four different direct seeding viz. direct seeding with spacing 15 cm × 20cm, 20 cm × 20 cm, 25 cm × 20 cm and broadcast seeding with the seed rate 80 kg ha^-1 and transplanting of 30 day-old seedling with 3 seedlings hill^-1 and two herbicides namely, Machete 5G (granular @ 25 kg ha^-1) and Ronstar 25EC (liquid @ 2 L ha^-1) were included as experimental treatments. The experiment was laid out in randomized complete block design with 3 replications. The data were analyzed statistically using M-STAT software and the treatment means were compared by DMRT. The interaction effect of herbicides and direct seeding methods was significant on the total number of weed m^-2 area. The highest number of total weed m^-2 area (43.33 ) was obtained from Ronstar 25 EC herbicide and broadcasting with a seed rate 80 kg ha^-1 which was statistically identical to direct seeding with spacing 25cm × 20cm. The lowest number of total weed (7.33) m^-2 area was obtained from Ronstar 25 EC herbicide and transplanting with plant spacing 15cm × 20cm and it was statistically identical to Machete 5G herbicide and transplanting with plant spacing 15cm × 20cm .

Achievement/Findings:

Four direct seeding viz., seeding with spacing 15 cm × 20 cm, 20 cm × 20 cm, 25 cm × 20 cm, broadcasting with seed rate @ 80 kg ha^-1 and transplanting of 30 day-old seedling with 3 seedlings hill^-1 were assessed on rice cv. Binadhan-4 with applying two herbicides, viz. Machete 5G and Ronstar 25EC in Aman season. The highest grain yield (4.04 t ha^-1) from direct seeding with spacing 20 cm × 20 cm with Machete 5G
