Abstract/ Executive Summary:

This study was conducted at farmers field in 15 districts of the country with the objective to demonstrate the benefits of DWSR using drum seeder over conventional transplanting method and motivate the farmers for adopting this technology to increase rice production. The result showed that DWSR produced higher grain yield irrespective of varieties and locations over TPR. BRRI dhan28 produced grain yield of 4.95 t/ha in DWSR in 7 locations, which was 16% higher than TPR. Similarly, BRRI dhan29, BRRI dhan36 and BRRI dhan47 produced grain yield of 6.16, 5.80 and 5.48 t/ha which were 8, 8 and 9% higher than TPR, respectively. Maximum yield advantage (on an average 16%) was found in BRRI dhan28 in DWSR than TPR. On an average, growth duration of BRRI dhan28, BRRI dhan29, BRRI dhan36 and BRRI dhan47 were reduced by 11, 14, 2 and 11 days, respectively in DWSR than TPR. As a result, farmers could harvest crop earlier and matured crop can escape from natural hazards.

Program Area: Farm Mechanization

Commodity: Seeder

Objectives:

The objectives were to demonstrate the benefits of DWSR using drum seeder over conventional transplanting method and motivate the farmers for adopting this technology to increase rice production.

Methodology:

A total of 37 demonstrations were conducted in 15 districts of the country at farmers field (Sylhet, Norsingdhi, Sunamgonj, Gazipur, Kishorgonj, Gopalgonj, Norsingdhi, Netrakona, Comilla, Jessore, Chittagong, Satkhira, Rajshahi, Naogaon, Cox?s Bazar). The varieties, BRRI dhan28, BRRI dhan29, BRRI dhan36 and BRRI dhan47 were used in the demonstrations. All varieties were not selected in all locations. Varietirs were demonstrated depending on the local demand and agro-ecological situations. For example BRRI dhan47 was given priority in saline regions. Each variety was demonstrated in 2 bighas of land. Required seeds, fertilizers, signboards, rice cultivation guideline were supplied to the respective farmers through DAE. For estimation of grain yield, 10 m2 samples were harvested from DWSR plots and adjacent farmers plots cultivated in normal transplanted method having the same variety. Grain yields were adjusted to 14% moisture content. Growth duration was calculated from same plots and farmers’ opinions about DWSR were recorded.
