Abstract/ Executive Summary:

The crop Soybean has a lot of impending possibilities in Bangladesh but at present, the production is not sufficient due to the use of low yield potential varieties, poor agronomic management practices, climatic conditions, pest concerns, and low fertility requirements. The study was aimed to find out the best yielding varieties suited for the Noakhali region among the available varieties. A field experiment was conducted at Halim Bazar, Suborno Char, Noakhali, a coastal district of southern Bangladesh, during Rabi season 2017-2018 to evaluate the growth and yield performance of BARI Soybean-5 and another BARI released archaic variety named Shohag. Ten replication combinations were tested. The experiment was laid out in randomized complete block design (RCBD) with ten replications. There were significant differences among the different treatment combinations in terms of growth and yield contributing characters. The highest seed yield was obtained from BARI Soybean-5 (1.75t/ha) and the lowest seed yield was obtained from the local variety named Shohag (1.41t/ha). The overall results indicated that the selection of modern variety BARI Soybean-5 produced the maximum seed yield of soybean in the char areas under Young Meghna Estuarine Floodplain soil (AEZ-16) of Bangladesh.

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Variety and Species

Commodity: Soybean

Objectives:

To evaluate the growth and yield performance of soybean varieties in the Noakhali region (char lands).

Methodology:

This experiment was conducted during the period of 2017-2018 at Halim Bazar, Suborno Char, Noakhali Sadar, Bangladesh. Geographically the experimental field was located in between 22°28' and 22°44' north latitudes and in between 90°59' and 91°20' east longitudes and the field belongs to the agro-ecological zone of the Young Meghna Estuarine Floodplain (AEZ-16). The experimental area remains under a tropical climate and the soil texture was sandy loam, maximum temperature was 34.3º C and the minimum was 14.4º C annually. (According to the weekly meteorological data collected by Suborno Char Upazila Agriculture Extension Office). The experiment consisted of two varieties namely BARI Soybean-5 and another archaic BARI released variety named Shohag (released in 1991). The experiment was laid out in a randomized complete block design (RCBD) with ten replications for each variety. The size of the unit plot was 8m x 5m and the net plot size was 800 m². The crop was sown during mid-December, 2017. The seeds were sown @ 60 kg ha^-1 in line with the row to row and plant to plant spacing of 30 x 10 cm, respectively. The crop was fertilized with 20- 50-45-3-1.5-1 kgha^-1of N-P-K-S-Zn-B, respectively. Half of the urea (in the form of N) and other fertilizers were applied at the final land preparation as basal dose. The rest of the urea fertilizer was applied after 25 DAS when the first wedding was done. Parameters observed were plants per square meter, plant height, numbers of branches per plant, numbers of pod per plant, numbers of seed per pod, 100 seed weight, and yield per ton per hectare. The recorded data on the different parameters of the study were analyzed statistically using an excel datasheet and SPSS software to find out the significance of the difference among the varieties.

Achievement/Findings:

Hence finally we can conclude that BARI Soybran-5 is better than the soybean variety Shohag. Shaheenuzzamn et al. (2014) evaluate three varieties of soybean named BARI Soybean- 5, BARI Soybean-6, and Shohag and recorded that BARI Soybean-5 showed the highest number of pods per plant, the highest number of seeds per pod was found in Shohag. Among these three varieties, the highest yield was obtained in the variety BARI Soybean-6.
