TL;DRAbstract
A basin lister cum seeder was developed as a rear mounted attachment to four wheel tractor of 35-45 hp range. It consists of common cultivator components, a three bottom basin lister and a cup feed type seeder. In laboratory calibration and field performance evaluation, the seed rate increased with increase in peripheral velocity of cup from 0.122 m/s to 0.356 m/s and further increase in peripheral velocity reduced the seed rate. The recommended seed rate was obtained for a forward speed of operation of 1.11 m/s. The seed spacing was influenced by forward speed of operation in laboratory condition. The forward speed of operation of 1.06 m/s registered the minimum standard deviation (0.83 per cent) from recommended spacing. The deviation of the basin profile was minimum upto a forward speed of operation of 1.11 m/s and thereafter the deviation was higher. Hence, the forward speed of operation was optimized as 1.11 m / s, considering the desired seed rate, seed spacing and basin profile.
