Analysis of straw bruising and sieving system on performance of modified wheat straw combine for better straw quality CIGR Journal
Dhimate, Ashish Satish; Mahal, Jaskarn Singh; Singh, Manjeet; Dixit, Anoop; Manes, Gursahib Singh; Khurana, Rohinish.
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...

Development of a tractor operated planter for direct sowing of onion crop CIGR Journal
Grewal, Raspinder Singh; Khurana, Rohinish; Manes, G S; Dixit, Anoop; Verma, Aseem.
Onion (Allium cepa L.) is one of the major vegetable crop grown throughout India. A six row tractor operated planter for direct sowing of onion was developed using inclined plate seed metering mechanism. Experiments were conducted for seed metering unit in the laboratory. Inclined plates having 18, 24 and 30 grooves were evaluated in the laboratory. Performance was evaluated on the basis of missing index, multiple index and quality of feed index. Missing index was highest in case of 18 groove plate at speed of 2 km/h. It decreased with the decrease in forward speed and also with the increase in the number of grooves of the metering plate. Minimum missing index was for 30 groove plate at the speed of 1 km/h. Multiple index was highest at speed of 2 km/h for...
