Mono-application of nitrogen (N) , calcium (Ca), and boron (B) fertilizers, combined application of NCa, NB, BCa, and NBCa were set at the flowering stage, treatment of no irrigation and no topdressing was set as CK1, only irrigation wihtout topdressing as CK2. Yield and related agronomic traits were analyzed under different topdressing treatments.The results showed that, compared with mono-topdressing, combined topdressing of N, B and Ca increased the pins per plant, fruits per plant and dry weight of pods by 18.61%-24.0%, 12.5%-23.0%, and 12.13%-21.60% respectively, thus increased the yield. Meanwhile combined application of three fertilizer increased the shoot dry weight, main stem height and branch number of peanuts, which could help to a better accumulation of the dry matter accumulation of each organ. In conclusion, the combined application of NBCa or NCa fertilizer at the pod-pin stage could effectively promote the growth of peanut and increase the yield. This study will contribute to determine the appropriate topdressing fertilizer types with drip irrigation under film. %U http://www.jouroilcrops.cn/EN/10.19802/j.issn.1007-9084.2020133
