Abstract/Description: | The most popular varieties of Tamil Nadu such as ASD18, ADT36 and IR20 were selected to investigate the influence of crop parameters on mechanical threshing of grains. The length of the paddy varieties ranged from 19.40 to 23.35 cm. The mean length of ASD18, ADT36 and IR20 were found to be 21.81, 21.80 and 22.50 cm, respectively. Among the varieties studied IR20 recorded maximum weight of grains per panicle of 2.90 g while the corresponding values for ASD18 and ADT36 were found to be 2.46 and 2.34 g, respectively. The maximum mean length and thickness and breadth were recorded by ASD18 and IR20, respectively whereas ADT36 recorded minimum values. The average thousand-grain weight of ASD18, ADT36 and IR20 varieties were found to be 21.86, 20.61 and 18.97 g, respectively. The variety ASD18 recorded the maximum bulk density of 590.6 kg m-3 followed by ADT36 (583.4 kg m-3). It is observed that the mean value of true density varies from 1128 to 1158 kg m-3 for the varieties and ASD18 recorded higher. The mean value of angle of repose varies from 31.7 degree to 38.0 degree. It is lower for ASD18, (31.7 degree) and higher for IR20, (38.0 degree). Based on these results, Rasp bar thresher was developed and their performances were studied. The overall dimension of the mini paddy thresher is 1500 × 900 × 1140 mm and its output capacity, threshing efficiency and grain damage are 248 kg h-1, 99 per cent and 1.73 per cent, respectively. The analysis of variance revealed that all the above discussed properties were significantly influenced (p<0.01) by the paddy varieties. |
