Photosynthesis parameters looked at were leaf area index (LAI), net assimilation rate (NAR), grain yield, flowering time, pod maturity period, growth duration and number of flowers and pods. The results were compared and evaluated among 7 mungbean varieties in order to identify varieties with good photosynthetic capacity, high yield and synchrony in pod maturity which may be used for crop production in suitable area. Those varieties with synchrony in pod maturity have a short flowering time, short pod maturity period and require two harvests. In this research, the synchrony in pod maturity varieties with high yield are OX12, OX18 and OX208. The variety with good photosynthetic ability (high LAI and NAR) is DXI8.
