Analysis of total nitrogen, chlorophyll content, ribulose‐1,5‐bisphosphate carboxylase/oxygenase activity and net photosynthesis rate was carried out on the leaves that support the developing pods in pigeon pea [ Cajanus cajan (L.) Millsp. cv. Prabhat] at several stages during pod filling. A continuous loss in all the above‐mentioned parameters was observed during the course of pod development. When no pods were allowed to develop by continuous flower removal treatment, there was a considerable delay in loss of all these metabolic parameters. Excision of pods after their mid‐development resulted not only in no further loss, but also in a significant recovery both of total nitrogen and of other investigated characteristics.
