Abstract/ Executive Summary:

At Comilla, the mean seed yield of the released variety Binasarisha-4 was the highest (1247 kg ha^-1) which differed statistically from other two lines but similar to mutant line MM-2-19-98 (1155 kg ha^-1). At Rangpur, the mean seed yield of the released variety Binasarisha-4 was the highest (1859 kg ha^-1) which differed statistically from other two lines but similar to mutant line MM-2-19-9 (1710 kg ha^-1). At Ishurdi, the mean seed yield of the mutant line Mut-98 was the highest (1099 kg ha^-1) followed by MM-005 (1083 (kg ha^-1). The mean seed yield due to spacing was the highest (1100 kg ha^-1) with 15 cm × 5~8 cm followed by the spacing 20 cm × 5~8 cm (1096 kg ha^-1) and 25 cm x 5~8 cm (1040 kg ha^-1). With the increasing of row spacing, the seed yields were decreased. The interaction results showed that the mutant line MM-005 produced the highest seed yield (1171 kg ha^-1) with the row spacing of 15 cm and 20 cm, respectively. The lowest seed yield (922 kg ha^-1) was recorded in the mutant line MM-025 with 20 cm row spacing.

Keywords: Spacing, Yield and Mustard

Location: BINA Sub-station farms at Comilla, Ishurdi and Rangpur

Start Date: 11-11-2009

End Date: 30-02-2010

Program Area: Variety and Species

Commodity: Mustard

Objectives:

To evaluate the effect of spacing on the yield and yield contributing characters of advanced mustard mutants/varieties

Methodology:

Three mustard mutants viz., MM-005, MM-025 and MM2-16-98 along with a check variety Binasarisha-4 were grown under four spacing- 15 cm × 5~8 cm, 20 cm × 5~8 cm, 25 cm × 5~8 cm and 30 cm × 5~8 cm during Rabi season of 2009-2010 at two locations. The locations were sub-station farms of BINA at Comilla, Ishurhi and Rangpur. The experiment was laid out in RCBD with three replications. The unit plot size was 3 m x 2 m. At maturity plant population count, yield and yield components were taken from the middle five lines of each plot and then converted per unit basis. Data on yield components were recorded from randomly selected 10 plants from those of five lines. The data were analyzed location-wise as per design used for the experiment using MSTAT Statistical Computer Program. Means of the results were compared by LSD.

Achievement/Findings:

Three mustard mutants and a check variety were grown under four spacing at three locations. Among the mutants/variety and spacing, Binasarisha-4 (1247 & 1859 kg ha^-1) and Mutant MM-005 (1098 kg ha^-1) and the closet spacing 15 cm (1198, 1962 & 1100 kg ha^-1) had the highest on average seed yields at Comilla, Rangpur and Ishurdi, respectively. The closest spacing at all locations produced maximum yield in all mutants/variety than the wider spacing 20-30 cm.
