Optimization of combine and crop parameters for harvesting of scented and non-scented paddy (Oryza Sativa) by head feed combine

摘要

A head feed combine was evaluated for optimization of combine parameters, viz. cylinder speed (14.42, 15.53 and 16.64 m/s), forward speed (3.5, 4.0 and 4.5 km/h), and crop parameter, viz. grain moisture content (18.1 to 22.4%) in relation to threshing efficiency, cleaning efficiency and total grain losses for scented and non-scented paddy (Oryza saliva L.) varieties. Moisture content of 18.1%, cylinder speed of 15.53 m/s and forward speed of 4.0 km/h was found optimum for harvesting of scented paddy variety Pusa 1121, whereas moisture content of 18.1%, cylinder speed of 16.64 m/s and forward speed of 4.5 km/h was found optimum for harvesting of non-scented paddy variety HKR 127.
