Abstract/ Executive Summary:

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh during Kharif-II season 2005 to investigate the effect of row spacing and cultivars on the growth and yield of soybean. Three soybean cultivars: (1) Bangladesh Soybean -4 (G- 2), (2) BARI soybean -5 (BS-5) and (3) Shohag (PB-1) and four row spacings, (1) 20 cm, (2) 30 cm, (3) 40 cm and (4) 50 cm were used in the experiment in a split-plot design with row spacing in the main plot and cultivars in the sub-plot. Seeds were sown on 26 July 2005 at specified rows maintaining 5 cm plant to plant distance. The highest seed yield was obtained from 20 cm spacing and yield decreased with increased spacing irrespective of cultivars. Among cultivars the highest yield was given by cultivar BS-5 which was followed by PB-1. It was concluded that the soybean cultivars BS-5 and PB-1 could be selected for sowing in Kharif-II season and should be planted at 20 cm apart rows for achieving higher yield.

End Date: 00-11-2005

Program Area: Crop-Soil-Water Management

Commodity: Soybean

Objectives:

To determine the response of several soybean cultivars grown under varying row spacings.

Methodology:

The experiment was conducted in Kharif-II season during July to November 2005 at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh. The experiment comprised four row spacings viz. 20, 30, 40 and 50 cm and three cultivars namely, Bangladesh Soybean-4 (G-2), BARI soybean -5 (BS-5) and Shohag (PB-1). The trial was conducted in a split-plot design with row spacing in the main plots and cultivars in the sub-plots. The treatments were replicated three times. The unit plot size was 4 m x 3 m. The seeds of each variety were inoculated with Rizhobium inoculum and then were sown on 26 July 2005 in rows following treatments. Three manual weeding were done at 21, 35 and 45 days after sowing (DAS). During first and second weeding, thinning was done to maintain a plant to plant spacing of 5 cm. No irrigation was given because heavy rainfall occurred during the whole period of the cropping season. The crop was infested by hairy caterpillar at vegetative, flowering and seed filling stages, which were successfully controlled by application of Dimethion 40 EC @ 1.5 L ha^-1 immediately after infestations. No disease incidence occurred in the crop field. The crop was harvested from central 6 m² (2.4 m × 2.5 m) area of each plot at full maturity (when about 80% pods turned into brown) on 27 October for cultivar G-2 and 13 November for cultivars BS-5 and PB-1. The post harvest processing such as threshing, cleaning and drying were done properly. Prior to harvesting, 10 randomly selected sample plants were uprooted and data on different growth characters and yield components were recorded. Crop growth rate, leaf area index and leaf area duration were recorded by destructive sampling of plants from 0.20 m^-2 area at 15 day intervals starting from 30 days after sowing. Dry matters of plant samples were also recorded at R5 stage (beginning pod stage) after drying in oven at 80 oC for 72 hours. The collected data were analyzed following ANOVA and mean comparison was done by DMRT with the help of MSTAT-C.

Achievement/Findings:

It may be concluded that soybean cultivar BARI soybean -5 (BS-5) could be sown at 20 cm apart rows to obtain higher yield in kharif II season.
