The impact of drip irrigation and phosphorus fertilizer on enhancing dimorphic seed production of Lespedeza potaninii in Northwest China

Water shortage and poor soil fertility are two main limiting factors for crop production in semiarid region. We evaluated the effect of five irrigation times (0, 2, 3, 4 and 5 times with 50 mm per time) and four phosphorus fertilizer rates (0, 60, 90 and 120 kg/ha) on chasmogamous (CH) and cleistoga...

Description
Summary:Water shortage and poor soil fertility are two main limiting factors for crop production in semiarid region. We evaluated the effect of five irrigation times (0, 2, 3, 4 and 5 times with 50 mm per time) and four phosphorus fertilizer rates (0, 60, 90 and 120 kg/ha) on chasmogamous (CH) and cleistogamous (CL) part of Lespedeza potaninii on seed yield, total seed yield, seed yield components and agronomic traits from the year 2022 to 2023. The CH and CL seed yield, total seed yield of L. potaninii was significantly (p
