Tillage pattern vs fuel consumption
The research aimed to identify an effective tillage pattern that optimizes fuel economy in Bangladesh's agricultural sector. The study compared three tillage patterns and found that the traditional mechanically-operated pattern required the least time and fuel consumption. Results indicated that while traditional and alternating patterns had the same fuel use, the traditional method was most efficient overall, suggesting the need for further research on a larger scale.

Crop sub sector alone contributes about 11% of the total GDP of the country and about 75% of the agricultural GDP (GOB, 2011). The status of the economy of Bangladesh in terms of output and employment still greatly depends on the agricultural sector.

It includes agricultural land development, harvesting, preparation for storage, and on-farm processing (Gatea, 2013).

A total numbers of 3,50,000 power tillers and 40,000 tractors are found to be available in Bangladesh (Wohab, 2013). In tillage operation, power tiller is suitable for saving labour cost, maintaining timeliness in operation, better quality of soil preparation and desired depth of tillage which has its ultimate bearing on soil fertility.

(1999). As a developing country, Bangladeshi farmers need to apply appropriate tillage pattern for saving fuel and reducing the cost of tillage in different soil condition all over the country.
- 10. The main objectiveof the research work was to find a suitable tillage pattern for fuel economy. OBJECTIVES Specific objectives were: • To select different tillage pattern from existing literature. • To select suitable land area for tillage operation. • To plow selected plots in different selected plowing method. • To measure the fuel consumption and time for individual tillage operation. • To measure the soil properties of the selected lands for plowing. • To analyse the collected data and prepare report we recorded.

SELECTION OF LANDAND TILLAGE PATTERN Three different patterns such as Straight alternation Tillage pattern, Circuitous tillage pattern and overlapping alternation or mechanically operated traditional tillage pattern were chosen to perform the tillage operation. Land was selected for application of different tillage pattern to increase the efficiency of fuel.

- 31. The experimentalresults shown that, for tilling of specific land (0.045 ha) with overlapping alternation or mechanically operated traditional pattern required minimum time (18 min) and consume lowest fuel (0.8 L). After tillage operation, traditional and alternation pattern both consume same amount of fuel (0.8 L) and tilling depth were also same (7 cm). Whereas, the time requirement was different for those two pattern.
- 32. Study shownthat the traditional tillage pattern is most effective and economic for tillage operation . Further study is necessary to confirm the results of conducting experiments with large area of land and with same tillage patterns.

- #2 Welcome to our presentation
- #15 Here the photographic view of land condition before tilling
- #16 this is the operational diagram for Circuitous tillage pattern. This pattern work from the outside of the field and finished at the center of the field.
- #17 here is the operational diagram for Straight Alternation Tillage Pattern. SATP start from one side of the field, until PT reached at the other side it will make a gap between two width of cut. When the PT return back the gap was tilled and complete the operation.
- #18 here is the working diagram for Overlapping Alternation Or Mechanically Operated Traditional Tillage Pattern. PT starts tilling from the point 1
- #20 Engine horse power was 13 hp and number of rotary blades 18 for the selected power tiller.
- #23 Before starting the tilling operation in the test plot, the fuel tank of the power tiller was filled up to its full. The quantity of fuel required to fill the tank fully after tilling the plot was measured to determine the quantity of fuel consumed for measurement of fuel consumption of the test plot. For each plot tilling time was recorded by the stop watch. A measuring scale made to penetrate tilled soil was used to measure ploughing depths. The depths of tilled soil were measured for thirty (30) times at different points along the ploughed field and then averaged to the soil depth of each tillage operation.

- #25 Soil moisture content was determined by gravimetric method on wet basis. Particle density of soil was determined by volumetric flask method. Bulk density of soil was determined by core sampler method. Soil texture was determined by the hydrometer method.

- #29 Soil properties are (% Sand, % Silt, % Clay) these parameters were used for determining the soil type for each plot of land. Another parameters was determined MC, PD, BD for each plot of land. Soil type was found sandy loam for each plot of land.
- #30 From the above study the lowest fuel consumption was (0.8 L) and lowest time required to till the specific land was (18 min) ) for traditional pattern.
