| It has transforming from subsistence farming which was dependent on human and animals, to mechanized farming using inanimate power sources like tractors, diesel engines, electric motors, etc. In Punjab agriculture, the human and animal power has substantially reduced from 7.5 to 0.69 % and 73 to 0.61% respectively due to increase in mechanical power from 17 to 76 % and electrical power from 1.7 to 23.5 from 1960-61 to 2012-13. The intensity of farm power availability has increased from 0.37 to 5.68 kW ha-1 during the same period. Correspondingly there has been increase in the cropping intensity (112 to 196%), production (3.16 to 28.58 mt) and productivity (668 to 3638 kg ha-1) of total food grains. |

| Wheat straw is a major feed source for ruminants. To retrieve the wheat straw and stubbles left after wheat harvesting operation with grain combines, another machine i.e. straw combine is used. But it was observed that the quality straw collected by straw combines contains dirt particles which increases total ash content of straw and that are harmful for animal health. To reduce energy requirement and to reduce total ash content, straw combine was developed with sieving system. Modified straw combine consisted of a 1.53×0.82 m screen with 0.208 mm opening sieving system, which was fixed below the bruising cylinder. Field evaluation of the modified straw combine carried out at two level of concave bar spacing (10 & 14 mm), three feed rate (14, 16.5... |
