Effects of Tillage and Sowing Methods on Soil Physical Properties and Corn Plant Characters

In the northeast plains of China, intensive utilization agricultural soils has been a persistent issue, and finding ways to utilize soil resources efficiently sustainably through scientifically-driven management system become crucial challenge for production. Conservation tillage is technology sustainable agriculture. Currently, plow rotary are dominant methods used in Mollisols, but there limited information on effects different conservation practices this region. The objective study was investigate short-term impact sowing physical properties corn plant growth examine relationship between characteristics during various stages growth. This consisted four methods: precision seeder (PTS), (RTS), no-tillage (NTS), precise stubble field (STS) (all treatments involved total straw return). results indicated that penetration resistance (SPR) 10–40 cm layer under PTS treatment significantly lower (by 11.9% 18%) compared other (p < 0.05). On average, moisture content NTS 2.7% 1.4% higher than RTS treatments. Additionally, temperature 5.6% 8.6% STS late also reduced bulk density surface soil. High SPR impeded early crop did not mid-crop development, while low one main factors affecting development as temperatures decreased. Based comparisons, we found implementation result significant decrease yield. We believe Mollisol regions feasible option.
