Abstract/ Executive Summary:

At Magura, the released variety Binatil-1 produced maximum mean seed yield (1441 kg ha^-1) which was mainly due to higher number of plant population and seed capsule^-1. Among the planting spacing, 20 cm x 5 cm produced the highest mean seed yield (1323 kg ha^-1) which was statistically significantly different from S₃ and S₄ but similar to S₁ and S₂. Results of the experiment showed that none of the crop characters recorded at Rangpur was significantly influenced by planting spacing except plant height. It was observed that the mutant line SM-12 produced mean seed yield of 986 kg ha^-1which was higher than Binatil-1 and contributed by the plant population and higher number of capsule. On the other hand, mean seed yield due to spacing was the highest 937 kg ha^-1with the closet spacing 20 cm x 5 cm mostly contributed by higher number of plant population and 1000 seed weight.

Keywords: Spacing, yield and sesame.

Location: Sub-station farm at Magura and Rangpur

Start Date: 20-02-2009

End Date: 05-06-2009

Program Area: Variety and Species

Commodity: Sesame

Objectives:

To evaluate the effect of spacing on the yield and yield contributing characters of sesame

Methodology:

An experiment was conducted in the sub-station farms of BINA at Rangpur and Magura to evaluate the effect of four plant spacing viz., 20 cm × 5 cm, 25 cm × 5 cm, 30 cm × 5 cm and 40 cm × 5 cm on the yield and yield contributing characters of sesame mutant SM-12 comparing with the check variety Binatil-1. The experiment was conducted following split- plot design with 3 replications. The unit plot size was 4.5 m x 2.5 m at Magura and Rangpur. Sesame mutant/variety was placed in the main plot and planting spacing in the sub plot. Data on yield attributes were recorded from randomly selected 10 plants from the middle of each plot. Plant population count, seed and straw yields were taken from the harvest of 5 middle lines and then converting per plot basis. All recorded data were statistically analyzed location-wise using the MSTAT Statistical Computer Package Program according to the design used for the experiment and data of each location were analyzed separately. Least significant difference (LSD) was used to compare variations among treatments.

Achievement/Findings:

One advanced sesame mutant along with a check variety was evaluated with four row spacing at Rangpur and Magura locations. At Rangpur, the advanced line SM-12 produced better yield than the check while at Magura it was reversed. Seed yields of both the locations with the spacing 20 cm x 5 cm and 25 cm x 5 cm were closer and also were higher than other two wider row spacing.
