Abstract/ Executive Summary:

The experiment was conducted at the Seed Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh during June 2010 to December 2011 to develop a suitable and low cost groundnut seed storage technology. Four storage container Polythene bag, Plastic pot, Tin container and Cloth bag and three initial seed moisture content (8%, 10% and 12%) were included in the present study to evaluate their effects on germination performance of groundnut seed. Experiment was arranged in completely randomized design with three replications. The highest germination performance was recorded from seeds stored at 8% initial seed moisture content (SMC) in polythene bags. The present study concludes that shelled groundnut seed could be stored safely from one rabi season to the next if stored in polythene bags after drying to 8% initial seed moisture content.

End Date: 00-12-2011

Program Area: Seed Technology

Commodity: Ground nut

Objectives:

1. To develop suitable techniques for storage of groundnut seed to study the effect of storage container on groundnut seed quality and to determine the effect of seed moisture content and relative humidity on groundnut seed quality.

Methodology:

The experiment was conducted during June 2010 through December 2011 to study the effect of storage environment on quality of groundnut seed at the Seed Laboratory, Department of Agronomy, Bangladesh Agricultural University (BAU), Mymensingh. Freshly, harvested seeds of groundnut cv. BINA badam4 was taken in four storage container (polythene bag. plastic pot, tin container and cloth bag) and three initial seed moisture content (8%, 10% and 12%) were included in the study. The groundnut seed was properly sun dried and the shelling of groundnut seed was done manually with care and safety to avoid mechanical injury of shelled seed. Completely randomized design was used with three replications. The seed quality parameters such as seed moisture content, germination (%), and vigour index were recorded at start of storage and also at 40, 80, 120 and 200 days after storage (DAS). The following parameters were measured by standard rules. The number of seedlings emerged each day were counted up to 15 days after sowing. Data analysis was done following analysis of variance technique adopting the design followed in each experiment using computer package programs (ANOVA) MSTAT–C. Mean comparison was done following Duncan’s Multiple Rang Test (DMRT) at 5% level of significance.

Achievement/Findings:

The result concludes that groundnut seed could be stored after shelling with high germination capacity (>80%) for at least 7 months (from rabi to rabi sowing) in polythene bags kept at ambient room conditions.
