Abstract/ Executive Summary:

Seed samples were collected from different parts of the plants. Fruit colour during each harvest were recorded. All seed samples were assessed for plant height (PH), base diameter (BD), fruit colour, 1000 seed weight and seed water content. And also moisture and germination percent were recorded storage after every two months. Seed samples of final harvest were stored at constant level of moisture which was 7.79% at average 37oC day temperature with air tide container. In this process quality of seed samples were good in the end of the year, normally it was not found.

Keywords: Determination, Field, physiological maturity, Kenaf seed

Location: green house premises, BJRI.

Start Date: 01-01-2010

End Date: 01-12-2011

Program Area: Seed Technology

Commodity: kenaf

Objectives:

To find out the optimum physiological & field maturity for kenaf seed harvest & for which the seed quality were remain better at the time of sowing even after storage.

Methodology:

Seed samples were collection just after seed formation until bursting of fruits at an interval of ten days. Seed samples were collected from different parts of the plants. Fruit color during each harvest were recorded. All seed samples were assessed for plant height (PH), base diameter (BD), fruit color, 1000 seed weight and seed water content. And also moisture and germination percent were recorded storage after every two months. Seed samples of final harvest were stored at constant level of moisture which was 7.79% at average 37oC day temperature with air tide container. At the end of harvest, germination percent were very from 60 to 95%. The germination level were constant 91 to 98% after one year which were not normal in kenaf seed.
