In this study, the possibility of growing silage corn, which is used as
an important nutrient in livestock and whose production is increasing in
recent years, by no-till seeding method under Erzurum conditions was
investigated. For this purpose, three silage corn varieties (DKC-5783,
Prestige, and ADA-9510) suitable for Erzurum's climatic conditions in
terms of vegetation period were selected from a large number of silage
corn seeds widely grown throughout Turkey and their development
conditions under no-till seeding conditions were investigated. A
precision vacuum no-till seeder with double disk type furrow opener was
used for silage corn seeding. Based on three different intrarow seed
spacings (10, 15, and 20 cm), physical properties of soil, plant
emergence, yield, and yield parameters as well as the planting
performance of the machine were examined. According to the results
obtained from the study, it was determined that mean emergence time
decreased and seedling emergence increased as intrarow seed spacing
increased. Furthermore, it was also found that DKC-5783 had the best
emergence time, the best seedling emergence percentage, and the highest
emergence rate index. Where yield decreased as intrarow spacing
increased, ADA-9510 had the highest yield among varieties. Generally,
intrarow seed spacing of 20 cm and DKC-5783 and ADA-9510 gave the best
results.
