Other claims from this paper (14)
- Intervention effect Sequential atrazine fb 2,4-D EE gave the highest grain yield, 11.37 t/ha.
- Intervention effect Grain yield under sequential atrazine fb 2,4-D EE was statistically similar to the weed-free treatment (11.24 t/ha).
- Observation Atrazine alone gave a grain yield of 10.36 t/ha, ranking after the sequential atrazine fb 2,4-D EE treatment.
- Intervention effect Sequential atrazine fb 2,4-D EE significantly lowered the total density and dry weight of weeds compared with other treatments.
- Intervention effect Application of atrazine fb 2,4-D EE gave the maximum weed control efficiency of 87.59 % at 30 DAS.
- Intervention effect Application of atrazine fb 2,4-D EE gave the maximum weed control efficiency of 95.91 % at 45 DAS.
- Intervention effect Application of atrazine fb 2,4-D EE gave the maximum weed control efficiency of 92.17% at 60 DAS.
- Intervention effect Application of atrazine fb 2,4-D EE gave the lowest weed index, -1.27%.
- Observation Yield loss due to weeds in the weedy check treatment was 50.99%.
- Observation Yield loss due to weeds under farmer’s practice was 43.17%.
- Intervention effect Sequential atrazine fb 2,4-D EE was the most effective treatment for controlling weeds, high yielding and economical among the weed control treatments.
- Intervention effect Atrazine applied once as pre-emergence was the next-best option for weed control in spring maize.
- Observation 16 weed species belonging to 6 families were identified in the spring maize field.
- Observation Broad leaf weeds and grassy weeds were more prominent than sedges.
