3. OBJECTIVES
1. To study the associated weed flora in soybean
2. To find out the suitable dose of Fomesafen and Propaquizafop
mixture for effective control of weeds in soybean
3. To see the effect of weed control treatments on growth and
yield of soybean
4. To assess the economics viability of treatments
