A. K. Pandey; Ved Prakash; H. S. Gupta The Indian Journal of Agricultural Sciences 2002
Other claims from this paper (13)
- Intervention effect Season-long weeds reduced babycorn yield by 44.0%.
- Intervention effect Weed-control treatments significantly improved yield attributes and babycorn and fodder yields against the weedy check.
- Intervention effect Weed-control treatments increased monetary returns against the weedy check.
- Intervention effect Weed-free treatment had the highest babycorn yield at 1.253 tonnes/ha.
- Intervention effect Weed-free treatment had the highest green fodder yield at 28.2 tonnes/ha.
- Intervention effect Hand weeding at 15 days plus earthing up gave yields comparable to weed-free treatment.
- Intervention effect Pendimethalin at 1.50 kg/ha gave yields comparable to weed-free treatment.
- Intervention effect Alachlor at 2.00 kg/ha gave yields comparable to weed-free treatment.
- Intervention effect Remaining treatments yielded considerably less than weed-free treatment.
- Intervention effect All weed-control treatments increased returns over the weedy check by Rs 4 010 to Rs 15 576/ha.
- Intervention effect Alachlor at 1.00 kg/ha plus hand weeding had the highest extra return of Rs 15 576/ha.
- Intervention effect Alachlor alone at 2.00 kg/ha ranked second in additional returns.
- Mechanism Weed-free treatment had considerably lower additional returns because it was costly.
