Experiment 2

 In the next test seeds were hand spaced in the row 1, 2 and 3 inches apart.

'Wen the plants were approximately 6 inches tall, thinning was performed using

a 6-inch cutting knife. The data presented in Table 2 indicates that the best

thinning was accomplished with the 3-inch spacing. It should be noted that

although the 40 and 50 plant stands are equally spaced from the desired 45 plant

stand, the 2-inch spacing resulted in more doubles.

 Experiment 3

 In the following tests the corn was seeded using different planters. In

 one test the Cole planter, with 42 and 32 pockets per plate, was used. Due to

 heavy rains and poor drainage of the plot area, it was not possible to thin these

 plants at the proper stage of growth. At thinning time the plants were over 10
