Abstract/ Executive Summary:

Seventeen demonstrations were conducted with BRRI Rice-Wheat thresher and BRRI Rice-Wheat reaper during wheat and paddy harvesting seasons.Among them five demonstrations were conducted in wheat harvesting season. The demonstrations revealed that about 68-75% of the farmers expressed satisfaction on the performance of BRRI thresher (TH7) for wheat and paddy threshing .However about 96% farmers wanted to purchase BRRI machines. Most farmers bided a lower price than the actual price of the machines. However, about 82-91% of the farmers expressed their options to use machines on rental basis and they offered a rental charge of Tk.750.0 - 1125.0 per ha which is more reasonable charge for profitable use of machines on rental basis. According to last years recommendation, BRRI Rice-Wheat thresher (TH7) was modified. The average wheat threshing capacity of the modified unit was increased to 385 kg/hr from 275 kg/ha (40%). However, the average paddy threshing capacity was increased more i.e up to 604 kg/hr from 375 kg/hr(61%). Most of the participants desired adequate demonstration of BRRI machines all over the country.

Start Date: 01-07-1999

End Date: 30-06-2000

Program Area: Farm Mechanization

Commodity: Farm machineries, Farm machineries

Objectives:

1. To determine the acceptability of the local made agricultural machineries at farm level. 2. To verify the quantitative and qualitative performances of the machines developed/ modified at BRRI. 3. To encourage local enterprises for manufacturing agricultural machinery. 4. To identify economically viable approach (s) for profitable use of the machines. 5. To modify the BRRI machines after farmers opinions 6. To compare the performance of BRRI machines over traditional methods of threshing

Methodology:

a) Site Selection Selection of sites was made on the basis of the following criteria: • easily accessible • of high cropping intensity area • an area of labour shortage (Suburb area, where labourer migrate to the urban area and Boarder area, where they might be engaged in other off farm job). b) Benchmark Survey Benchmark survey was conducted through a questionnaire c) Farmers opinion on the machine performance A questionnaire was prepared and respondents were asked questions relating to 1. social acceptability, 2. technical performance, 3. profitability/social benefits, 4. effectiveness of communication and training programs, 5. private entrepreneurship possibility for equipment repair and maintenance and 6. maintenance needs of the equipment d) Modification On the basis of farmres opinion obtained in last years demonstrations the thresher (TH-7) was modified and tested at BRRI as well as in famers field at Baliadangi, Thakurgaon. e) Demonstration At each site at least 50 participants mostly farmers were invited and machines were operated before them at least for half an hour. A short questionnaire were supplied to the participants asking their opinion/comments on machine performance. Afterwards data were analysed and discussions were made.

Achievement/Findings:

1. Threshing and harvesting could be done quickly using these machine 2. Thresher was better than Reaper 3. Farmer cultivated wheat about 3 time than last year because they knew that they would get 4. BRRI machine 5. Machines were insufficient with respect to wheat area 6. Wheat had been stacked by farmers and waiting for BRRI machine 7. BRRI machine had attracted farmers
