Assessment of plot size and tillage pattern on the economy of fuel consumption in land preparation using tractors and power tillers at different soil moisture conditions in Dinajpur District, Bangladesh

摘要

The study was conducted to determine the most frequent class sizes of land area cultivated by farmers in Dinajpur District to conserve fuel consumption for tillage operations using tractors and power tillers. From 6 different unions of Birganj Upazilla, Dinajpur, total 270 plots 18 different villages were studied 15 plots from each village. From the studied areas, it was found that plot sizes varied from 75.44m2 to 2162.09m2. However the most frequent sizes were found between 101m2 and 700m2 coverings almost 88% when grouped into size classes at 100m2 interval. Also different shapes of plots were found from the study such as rectangular, trapezoidal, pentagonal, hexagonal, octagonal, square, parallelogram etc., however, rectangular, trapezoidal, pentagon and hexagonal shapes covered almost 90% of the plot area measured. In case of fuel consumption tests, second and third tillage were found to consume less fuel than the first one. Also lengthwise tilling operations were found to consume less fuel than widthwise operation.
