WEED DYNAMICS IN RICE BASED CROPPING SEQUENCE IN CAUVERY DELTA ZONE

Abstract

                                Experiments conducted in a farmer's field with clay loam soil in Cauvery delta zone during 1993 and 1995 revealed that broad leaved weeds constituted the major weed flora followed by grasses and sedges in rice grown during thaladi season and in relay sown blackgram. In case of sesame, either sown immediately after rice or after blackgram or after a fallow period, grasses dominated the weed flora followed by broad leaved weeds and sedges.

Key words : Rice, Cropping sequence, Weed dynamics
