  • Abstract:
  • Finger millet is an important crop among the small millets and third among millets in the area and production after sorghum and pearl millet in India. It is cultivated as a rainfed crop for its valued food grains and adaptability to a wide range of geographical areas and agro-ecological diversity in India. Finger millet occupies an important place in the agriculture of the Uttarakhand hilly regions. In the state of Uttarakhand, sowing of majorly grown finger millet still rely on broadcasting method. Sowing by broadcasting involves randomly scattering of seeds on the seedbed which results in higher seed rate. Hence a sponge pad and disc type metering mechanism metering were evaluated for two speed ratios levels 1:11 and 1:58. The metering mechanism was tested in laboratory at five speed levels (2,3,4,5 and 6 km h-1) The result revealed that initially there was a slight increase in seed rate with the increased in forward speed from 2 to 3 km h-1. When the forward speed increased from 3 to 4 km h-1, the seed rate was decreased. The maximum and minimum mean seed rate for speed ratio 1:11 was found to be 19.79 kg ha-1 at forward speed of 3 km h-1 and 18.29 kg ha-1 at 4 km h-1, while when the speed reduction ratio reduced from 1:11 to 1:58. The seed rate was also be declined from 19.79 to 14.19 kg ha-1 when speed was increased from 3 to 4 km h-1. As the forward speed increased beyond 4 km h-1, the seed rate was started to be declined. The effects of forward speeds on different indices were found insignificantly at 5 % confidence level on seed rate of finger millet while the effects of forward speed on seed spacing and speed ratio on seed rate was significant at 5 % confidence level.
