Effects of the twin-row planter with subsoiling on soybean growth and yield in northern China

Twin-row ridge cultivation is widely used in soybean planting northern China. In order to find the optimal parameters of agronomy, twin-row planter with subsoiling was designed. Field experiments were conducted evaluate effects plant arrangements and cluster densities on growth grain yield under different tillage treatments. The experiment a randomised complete block design consisting 20 treatments 2×2×5 factorial arrangement. Two inter-row no subsoiling. Each treatment included combination (side-by-side arrangement triangular arrangement) (one, two, three, four, five plants). variables measured soil moisture content, seedling emergence, biomass accumulation allocation, yield. We have concluded that performance much better than treatment. Meanwhile, two plants per best choices for This study provided reference innovative optimisation agronomy.
