Determination of Some Engineering Properties of Selected Groundnut or Peanut Varieties

Abstract:

The study has been conducted to investigate the engineering properties of popular varieties of peanut grown in Raichur, Karnataka region viz., R-8808 and KADARI-9 were selected. The mean length and height of peanut plant was found to be 517.95 mm and 631.75 mm. The mean length and thickness of peanut pod was found to be 21.72 mm and 11.91 mm, respectively. The number of pods per plant was found to be 16 and mean weight of thousand peanut pod was found 1262.46 g. The mean moisture content of the freshly harvested peanut pod and vine was observed as 38.90 to 39.23 per cent and 41.25 to 41.392 per cent. The mean roundness of peanut pods was found 0.685. The mean aspect and pod vine ratio was found 0.955 and 3.70. The mean value of force required to detach the pod from vine was found 4.92 kg. The terminal velocity of peanut pod and vine was found 8.12 to 10.25 m s-1 and 4.39 to 4.52 m s-1. The mean angle of repose of peanut pods was found 28.22°. The mean value of coefficient of friction was found to be maximum 0.577 on wood, where it was minimum 0.432 on MS sheet.
