The reasons for low yield potential in mung bean (Vigna radiata (L.) Wilczek) are discussed, using some physiological parameters that regulate crop growth and developmental processes. A slow rate of early vegetative growth contributes, at least indirectly, towards lower yield. However, there is potential for improvement. Light and temperature optima for maximal photosynthetic rates have been evaluated. Greater demand for N and low uptake from soil accentuates N remobilization from leaves resulting in rapid decline in leaf photosynthetic activities. It has been suggested that improvement of source strength through adequate N fertilization would stop or reduce remobilization of photosynthates from leaves and abscission of reproductive organs. An equation for the yield-density relationship in mung bean has also been worked out.
