Abstract
Cotton (Gossypium) being a fluffy staple fiber that grows in a boll is one of the major crop produced in India accounting 22 percent of world total production. In India 500 million tons of crop residue are prouduced annually out of which 90-150 million (Bhuneshwari et al ., 2019) are burned in the field and after harvesting of cotton, the leftover cotton stalk (crop residue) are generally burned in the field causing pollution or slashed to certain depth without uprooting which require considerable amount of labour and drudgery. Therefore, a cotton stalk up-rooter attachment for shredder was developed to solve the issue of cotton crop residue management problem in the field. The field evaluation of the machine was conducted at stalk uprooting depth of 150 mm, 200 mm and 250 mm and forward speed of tractor of 1.5 km/h, 2.5 km/h and 3.5 km/h as independent parameter and were evaluated for field capacity, field efficiency, power requirement, draft requirement, wheel slippage, fuel consumption, stalk uprooting width and uprooting efficiency as dependent parameters.
The depth of operation of 200 mm and forward speed of 2.5 km/h was found suitable for uprooting cotton stalk. The field efficiency, power requirement, draft requirement, wheel slippage, fuel consumption, stalk uprooting width and uprooting efficiency were found to be 0.22 ha/h, 76.58 per cent, 4.514 kW, 653.5 kgf, 12.81 per cent, 6.49 lit/h, 360 mm and 98.08 per cent, respectively. Cost of operation per hectare of cotton stalk shredder without stalk up-rooter attachment was found to be Rs. 1867.5 and for cotton stalk shredder with stalk up-rooter attachment was found to be Rs. 2670.26. The cotton stalk up-rooter attachment machine uprooted the cotton stalks from the soil and worked satisfactorily in the field.
