Nine different experiments were conducted in the study of factors affecting germination and emergence of sorghum. Six varieties, Sooner, Kalo, Feterita, Leoti, Early Sumac, and Atlas have been used throughout the different studies.

Depth of planting studies showed that satisfactory stands of sorghum seedlings could be obtained when the seed was planted to depths of three, four, and five inches. Negative results were obtained from a presoaking study. No increase in germination was affected by presoaking sorghum seed for 1, 4, or 12 hours previous to planting. Laboratory germination of sorghum seeds at temperatures of 10°, 15°, 20°, and 25° C showed a direct relationship between temperature and rate of germination. The tendency toward a linear relationship exists between weight of seed and height of seedlings of sorghum. Medium and large kernels give highest percentages of germination in most cases.
