A prototype punch planter for no-tillage corn was developed to provide different seed spacing. Plant distribution per feddan was adjusted by changing planter punch connecting rod. Seed spacing of 136, 163, and 194 mm were obtained by changing the reciprocating crank radius with different punch tube lengths, represented 550, 450, and 350 mm respectively.The machine is constructed, manufactured and tested in experimental lab. at agricultural engineering Mansoura University. The effect of an oscillating tube mechanism on the seed's distribution by calculating seed's spacing, miss index, multiples index, and quality of feed index, precisions in spacing and the amount of seed rate was recognized. The data were statistically analyzed to determine the effect of the oscillating tube radii and the traveling speed of punch planter under three different of the connecting rod length "punch reciprocated radius" (35, 55 and 100 mm) on performance. The smallest punching tube length (350 mm) had the best results at 0.39 m/s, with a quality of feed index of 95.1% and precision of 3.92%. The multiples index and miss index, not always significant, as complementary of quality of feed index, were the lowest at 0.39 m/s.
