Intercropping of greengram with blackgram in replacement series of I: I ratio significantly reduced dry maller accumulation and sulphur depletion by weeds as compared to sole cropping of greengram and blackgram. Fluchloralin (1.0 kg/ha) and hand weeding at 25 days after sowing brought about significant reduction in weed intensity, dry maller accumulation and sulphur depletion by weeds over weedy check. Fluchloralin resulted in highest grain yield in both greengram and blackgram. Application of sulphur resulted in significantly higher dry maller accumulation and sulphur depletion by weeds in comparison to control. Grain yield of greengram as well as blackgram was significantly higher under sulphur fertilization over control.
