Abstract/ Executive Summary:

A field experiment was conducted in the Field Laboratory of Agrotechnology Discipline in Khulna University to evaluate the effect of row spacing on the yield and yield contributing characters of sesame during Kharif season, 2007; using the varieties (V1 = T6, V2 = Batiaghata local Til and V3 = BINA Til) and the row spacings (S1 = 15 cm, S2 = 30 cm and S3 = 45 cm). Yields were significantly influenced by the varieties and row spacings. The highest seed yield was produced by the variety BINA Til while the lowest was by the variety Batiaghata local Til and the highest seed yield was produced by row spacing 30 cm while the lowest was by row spacing 45 cm. Seed yield was well correlated with capsule plant and seeds capsule. -1 -1

Program Area: Crop-Soil-Water Management

Commodity: Sesame

Objectives:

This study was designed to see the effect of row spacing on yield components and yield of three sesame cultivars under the agro-ecological conditions of Khulna.

Methodology:

The experiment was conducted during Kharif season at the experimental field of Agrotechnology Discipline of Khulna University, Khulna. The experimental location experiences a sub-tropical climate. The experiment consisted of sesame varieties: i) T6 (V1), ii) Batiaghata local Til (V2) & iii) BINA Til (V3) and of row spacings: i) 15 cm (S1), ii) 30 cm (S2) & iii) 45 cm (S3). The experiment was laid out in a double factor randomized complete block design (RCBD) with three replications where each unit plot was 3 m × 2 m with 27 treatments. The distance between two adjacent unit plots and that of blocks were 0.25 m and 0.75 m, respectively. The experimental plots were fertilized with poultry litter @ of 3 t ha during the land preparation and -1 P205, fertilizers @ 60 kg N, 175 kg 60 kg K20 & 120 kg gypsum per hectare respectively, were also applied. An additional quantity of 60 kg N per hectare was topdressed during flower initiation in the form of urea. Seeds were sown on April 18, 2007 in solid lines with plant spacings 15 cm × 10 cm, 30 cm × 10 cm, 45 cm × 10 cm. Seeds were placed at 2 cm soil depth being covered with loose soil properly. The seedling emerged between April 23-25, 2007. Missing hills were sown with seeds to maintain desired plant population. Weeding followed by thinning was done at 12 days of emergence and 20 days after emergence. Irrigation was done 2 days after sowing to facilitate germination of seeds and before flowering in order to maintain adequate moisture in the field. Some of the experimental plots were damaged by stink bugs, mainly the plots of the variety T6. To control the bugs insecticide Malathion 57 EC was applied twice @ 0.2%. At maturity (when about 80% of capsules turned brown colour) the experimental crop was harvested variety-wise. The collected data were analyzed statistically by using the analysis of variance (ANOVA) technique with the help of the computer package MSTAT-C. The mean differences among the treatments were compared by Duncan's Multiple Range Test (DMRT). Functional [7] relationships were developed between yield and yield attributes by using simple regression analysis.

Achievement/Findings:

Conclusion: It could be concluded that a higher seed yield of sesame could be obtained by using BINA Til sowing at 30 cm row spacing under the agroclimatic conditions of Khulna. The experiment was, however, conducted for only one season and hence the results be considered tentative.
