Abstract/ Executive Summary:

The study was conducted in Sreepur (Gazipur) and Amirpur (Chuadanga) to represent two different agro-ecological environments of Bangladesh namely favourable upland and drought prone situation with a view to know the causes for farmers' preferences towards own seed stock and to assess farmers' seed management practices.In each site thirty selected farmers conducted the experiment in a parcel using manually clean seed and own saved seed side by side. The same parcel was used for the experiment as well as for the check plot to dissociate the effect of other factors such as top-sequence, soil type and quality and access to irrigation. Seed lot with insect damage and seeds mixed with weed seed resulted substantial yield reduction as reported by 100% and 90% farmers respectively in Sreepur. More than 90% farmers in Amirpur mentioned that rice seed mixed with weed seed and seed mix with off-types caused substantial yield reduction.

Keywords: Effect, Management intervention, Improving rice seed quality, Yield

Location: Gazipur and Chuadanga

Start Date: 01-07-2005

End Date: 30-06-2006

Program Area: Socio-economic and Policy

Commodity: Rice

Objectives:

To know the causes for farmers' preferences towards own seed stock;
To assess farmers' seed management practices in the study areas; and
To understand farmers' idea on yield reducing factors and examine the effect of clean seed in increasing rice yield

Methodology:

The study was conducted in Sreepur (Gazipur ) and Amirpur (Chuadanga) to represent two different agro-ecological environments of Bangladesh namely favourable upland and drought prone situation. In each site thirty selected farmers conducted the experiment in a parcel using manually clean seed and own saved seed side by side. The same parcel was used for the experiment as well as for the check plot to dissociate the effect of other factors such as top-sequence, soil type and quality and access to irrigation. All the agronomic practices were similar in both the plots. From each clean and farmers 'seed plot, a 2 m x 3 m area was harvested at maturity stage. Fresh grain weights and moisture were also recorded immediately after harvest. To determine the yield, moisture was adjusted at 14% level. Data were analyzed using paired t-test.
