The effect of wheat straw management techniques (Straw removal-control, straw incorporation-SI, straw retention-SR) on some physiological parameters, growth and yield of summer mung were investigated in a field experiment on sandy loam soil. SI increased plant biomass and N-uptake at 24, 34 and 45 days after sowing (DAS) and at maturity but lowered chlorophyll content of leaf at 34 DAS. SR decreased leaf area index (LAI) and plant biomass while plant height increased at each sampling date. Nodulation and nitrogenase activity at peak flowering stage (45 DAS) increased with SI but decreased with SR. Seed yield improved with SI but decreased with SR. The results suggest that in summer mung, wheat straw incorporation is a superior straw management practice than removal or straw retention.
