Abstract
Tillage is mechanical manipulation of soil for providing optimum environmental conditions required of plant growth. The reduction in labour and shorter window period between two successive crops of wheat and paddy requires effective mechanization to increase production. A large amount of energy is required for seed bed preparation and a small fraction of improvement in tillage equipment can save a significant amount of energy. Rotavator (or rotary tiller) is such a tool that can prepare the seed bed in a single operation thus saving time and energy. In this paper, the performance of rotavator being manufactured by different manufacturer in Punjab was studied. The data was collected from the test reports of rotavators of 20 different make and model tested by Farm Machinery Testing Centre, Punjab Agricultural University, Ludhiana during the period 2006–2011. Great variation for pulverization index was observed. Fifty percent machine has puddling index in the range of 65–70 %. And for mixing of crops for green manuring into the soil, 70 % machines have mixing index 80 %. All the rotavators studied used ‘L’—shape blade.
