The most rapid decomposition occurs when residue is placed 10 cm deep and when stalks are shredded as finely as possible also. The present migration of labour from rural sector to scholastic jobs in urban areas necessitates the need for mechanizing the farming operation of cotton stalk shredding and incorporation in the field. A tractor operated cotton stalk shredder consisting of a shredder assembly, power transmission system with hydraulic motor, hitch frame and hydraulic lift was developed. The shredding unit consisted of main shaft and two swing back type rotary blades. Lifting and lowering of the shredding unit was carried out by the hydraulic lift mounted in the front of the tractor. The power for the shredder was transmitted form the hydraulic motor and reduction gear box. The commercially available ro-tavator was used as insitu applicator for incorporation of shredded cotton stalks Shredding cotton stalks was accomplished by the shredder in front portion of the tractor and incorporation of the shredded cotton stalks into the soil was done by rotary tiller in the rear portion of the tractor. The unit was evaluated for performance. Experiments were conducted with 4 treatments; viz. disc ploughing with the standing cotton stalks, operation of the cotton stalk shredder cum insitu applicator at 2.0, 2.5 and 3.0 km h-1 to find out the efficient method of cotton stalk shredding and insitu application.Not Availabl
