A field experiment was conducted to identify effective weed management practice and to study the influence of weed management on the weed flora of succeeding crops in rice-sunflower eropping system. Application of anilofos 0.4 kg/ha or butachlor 1.5 kg/ha or 2,4-DEE 1.0 kg/ha at 5 DAT was found equally effective in suppressing weed growth and inereasing grain yield of rice. Application of herbicides and hand weeding to sunflower did not influence the weed control and growth in kharif rice. During rabi, applieation of oxyfluorfen 0.15 kg/ha and metolachlor 1.5 kg/ha to sunflower was effeetive in eontrolling weeds and resulted in similar yield to that of hand weeded (20 DAS) crop. On the other hand, all these weed management treatments resulted in signifieantly higher seed yield over that of unweeded control. Application of herhicides and hand weeding in rice had no effect on weed growth of succeeding sunflower erop in rabi.
