Mungbean (Vigna radiata L.) is a leguminous crop having capability of fixing atmospheric nitrogen through specific bacteria present in nodulated roots. To study the physiological response of mung bean ( Vigna radiata L. ), an experiment was conducted at Barani Agricultural Research Station, Fatehjang to examine five Mungbean genotypes viz., AZRI Mung 2006, NM 2006, Chakwal Mung 2006, Chakwal Mung 97 and NCM 209 under normal and late sowing dates. Data on mungbean growth, development and grain yield were recorded from twenty randomly selected plants. Among all these varieties, AZRI-Mung 2006 ranked first in terms of yield (715.28 kg/ha) followed by Chakwal Mung 2006 (678.12 kg/ha), NM-2006 (632.45 kg/ha), Chakwal Mung 97 (598.11 kg/ha) and NCM-209 (537.29 kg/ha). Maximum grain yield 687.11 kg/ha was obtained under normal condition as compared to 411.43 kg/ha under late sowing condition. AZRI-Mung 2006 was found consistent under both planting condition while NCM-209 showed sensitivity under late sowing condition.
