Abstract

To study the effect of sole and sequential application of herbicide on economic benefits of maize crop by reducing the crop-weed competition during entire crop growth period. In kharif season maize, crop suffering from continuous rainfall problems that is why management of weed becomes big challenge front of us that time. These challenge effects to the uptake of nutrients and economics of crop. For this purpose, a field experiment was conducted during the kharif 2019 at Agricultural Research farm of TCA Dholi under the RPCAU Pusa, Samastipur (Bihar) in maize crop. The treatments were viz; T1: Weedy check, T2: Topramezone 25.2 g/ha, T3: Tembotrione 120 g/ha, T4: Atrazine 1 kg fb HW, T5: Atrazine 0.75 kg/ha fb Topramezone 25.2 g/ha, T6: Atrazine 0.75 kg fb Tembotrione 120 g/ha, T7: Atrazine 1 kg fb Topramezone 25.2 g/ha, T8: Atrazine 1 kg/ha fb Tembotrione 120 g/ha, T9: Topramezone 25.2 g/ha + Atrazine 0.75 kg/ha, T10: Tembotrione 120 g/ha + Atrazine 0.75 kg/ha, T11: Weed free, allocated

Keywords

B: C ratio Cost of cultivation, Net return, Tembotrione, Topramezone.

Conclusion

Mainly kharif season maize crop suffering from the continuous rainfall. That time management of weed becomes very difficult because of rainfall. So, application of herbicides reduces the effect of weeds on the crop and it’s also increases in the uptake of nutrients and economic value of grain. Herbicide reduces the cost of cultivation that is why farmer can get more profit from the production of crop and increases production level of the crop.
