Abstract

Short-duration pigeonpea (Cajanus cajan (L.) Millspaugh, cv. ICPL 87)) responded to applied N by increasing its shoot and rwt growth in a Vertisol field at ICRISAT Center in India. However. growth of shoot and roots was impaired and N concentration in leaf was decreased by short-ten (three days) waterlogging. During the recovery phase pigeonpa developed new adventitious rwts around the base of tap root with new nodules. Therefore waterlogged pigeonpea had higher total nodule activity than control plants and there were no differences in N concentration in ieaf at 40 days after the termination of waterlogging.
