Abstract

Five healthy seeds of mungbean were sown in earthen pots filled with field soil and farm yard manure (6: 1) which were thinned to two plants after germination. Fluchloralin at 0.7.5, 1.0 and 1.2.5 kg/ha was incorporated in the soil before sowing. Pendimethalin at 1.0, 1.5 and 2.0 kg/ha was applied as pre-emergence spray 2 DAS. While sethoxydim at 0, 7.5, 1.0 and 1.25 kg/ha applied as post-emergence spray 15 DAS. All the treatments decreased the length of shoot and root alongwith number of leaves and their dry weights of treated plants in comparison to control plants at all the stages of sampling. Fluchloralin and pendimethalin increased the number of nodules/plant alongwith their fresh weights upto recommended dose. But the leghaemoglobin content of nodules decreased in all the treated plants. As a result, the nitrogen fixing efficiency was reduced at 30 DAS in mungbean.
