Abstract:
Three early-maturity and one late-maturity vegetable-type soybean cultivar were used as materials to study the effect of topdressing urea at R1 on agronomic traits and yield.The early-maturity vegetable-type soybeans had shorter plant height,fewer branch and nodes,and lower height of the lowest pod than that of the late-maturity cultivars.Topdressing urea at R1 had no remarkable influence on its morphological traits,but increased the percentage of 2-seed and 3-seed pods,and the effect of 75 kg·ha-1 was better than 150 kg·ha-1 urea.Topdressing suitable amount of urea at R1 also increased the pods per plant,pod weight per plant,seeds per plant,100-seed weight,seed yield and harvest index,and the yield-increasing effect was better than late-maturity ones.Based on the yield performance and response to N fertilizer,early-maturity vegetable-type soybean Shennongyin 48 has better application perspective.
