Rate and Time of GA₃ Application and Irrigation on Plant Morphology and Yield of Lentil

摘要

There is little known about how, or whether, GA₃ affects development of lentils (Lens culinaris Medikus subsp. culinaris). In the field, lentil was treated at two times with four concentrations of GA₃ and with or without irrigation. Concentration of GA₃ affected plant height, numbers of branches and pods, 100 seed weight, and yield. The 10 mg·L-1 concentration of GA₃ resulted in increased yield and increased percentage of pods with two seeds. The 50 mg·L-1 concentration of GA₃ produced more branches. Application of GA₃ at flowering increased yield by 60%. Irrigation produced the greatest number of pods and the highest yield. Lentil production can be increased by applying concentrations of GA₃ between 10 and 50 mg·L-1 at flowering.
