Abstract

Physio mechanical properties of cotton stalk is important for design of cotton stalk shredder cum uprooter. The current investigation about the physical and mechanical properties of cotton stalk. The average height of plant, stem diameter (bottom, middle and top portion), weight of one stalk, number of branches and moisture content, were 1007.40 mm, 10.42, 8.45 and 4.39 mm, 33 g, 14 and 28.7 per cent (wb), respectively. To find the mechanical properties cotton stalk divided into three portions. The average value of cutting force (top, middle and bottom) and cutting force (top, middle and bottom) portion of cotton stalk for cutting were found as 360.64, 1201.38, 1785.66 and 83.02, 163.01, 379.77 N, respectively. The minimum cutting force and fracturability360.64 N and 83.02 N was found at top portion and maximum cutting force and fracturability1785.66 N and 379.77 N was found at bottom portion, respectively. The hardness (top, middle and bottom) portion of cotton stalk for bending were found as 14.34, 60.62, 135.93 N, respectively. The minimum bending force 14.59 N was found at top portion and maximum bending force 135.93 N was found at bottom portion.

Conclusion

—The physical properties viz., height, diameter (bottom, middle, top portion), no of branches, weight and moisture content of cotton stalk were 1007.40, 10.42, 8.45, 4.39 mm, 14, 33 g and 28.7 per cent (wb), respectively. —The mechanical properties viz., cutting force (bottom, middle, top), fracturability (bottom, middle, top) for cutting test and bending force (bottom, middle, top) portion for bending test of cotton stalk were obtained as 1785.66, 1201.38, 360.64 N, 379.77, 163.01, 83.02 N and 135.93, 60.62, 14.34 N, respectively.
