Abstract: To address the issue of timeliness and reducing drudgery in manual operation and to provide an alternative to broadcasting of paddy, the studies of inclined metering mechanism was taken up with thirteen different prominent varieties of paddy. The different inclination and different gear ratio of inclined metering plate was tested in laboratory and field condition for correct seed rate. The inclined plate has provision for changing the plate rpm at the given forward speed. The laboratory test work carried out in the workshop of Department of Farm Machinery and Power, SVCAET&RS Faculty of Agricultural Engineering, IGKV Raipur. The physical properties such as Length or Longitudinal (L), Width (W), Thickness (T), and Mass (M) were measured at a moisture content of 13.34 ± 0.53% (dry basis) and the following results were obtained: the average split length, width, thickness and unit mass of 1000 seeds are 8.74 mm, 2.46 mm, 1.85 mm and 22.97 g respectively. The calculated physical properties like the geometric mean diameter, surface area, porosity, sphericity, true density and aspect ratio was found as 3.413 mm, 36.2 mm2, 49.2 %, 40.0 %, 1.110 g/ml and 30.4 % respectively. The thirteen varieties were Mahamaya (V1), IR 36 (V2), Purnima (V3), Danteshwari (V4), Karmamasuri (V5), Bamleshwari (V6), Chandrahashini (V7), Swarna (V8), Maheshwari (V9), IGKV R1 (V10), Jvaful (V11), Indira Barani (V12) and HMT (V13). In lab test the metering device was tested in all three inclination angle and four gear ratio viz. 50°, 60°, 70° and 1: 1, 1.31:1, 1.57:1 and 1.94:1 respectively. The results of lab test shows that the seed rate increase with decreasing the angle of inclination of metering plate and also increasing with decreasing gear ratio for all thirteen varieties of paddy. The laboratory studies revealed that about 20 – 25 kg/ha seeds rate should be obtain at an angle of 60° and in gear G3 (1.57:1 gear ratio) and G4 (1.94:1 gear ratio) for all the thirteen varieties of paddy. The seed damage in inclined plate planter was negligible. Based on the laboratory test 50° and 60° inclination angle of metering plate, and gear G3(1.57:1 gear ratio) and G4(1.94:1 gear ratio) and forward speed of 4.5 km/h was selected for field testing on the inclined plate planter. The performance of the inclined metering device was found to be satisfactory in the field for all thirteen varieties of paddy. Average seed rate of one varieties namely R1 (Rajeshwari) of paddy was about 20-30kg/ha which is 50% less than the line sowing by fluted roller seed drill. The average miss index, multiple index and plant population/m2 for two varieties was found to be only 5.3%, 8.2% and 68 plant/m2, respectively, which was within acceptable limit.
