Other claims from this paper (9)
- Observation No significant difference in the species composition of weeds was found between the two corn hybrids.
- Intervention effect In the block kept weed-free for the first 10-50 days, yield losses of the Krasnodar 291 AMV hybrid decreased, amounting to 39.21-7.99 %.
- Intervention effect Zernograd 354 MV corn weeded throughout the growing season yielded 3.88 t/ha, a 53.98 % decrease compared with weed-free sowing.
- Observation In the first block both corn hybrids showed a significant decrease in yield.
- Observation A decrease in the competitiveness of the corn hybrids was observed, evidenced by high susceptibility to pests and diseases.
- Observation In the forest-steppe zone of the Chechen Republic the critical period of weed harmfulness for the mid-early corn hybrid Krasnodar 291 AMV is the first 30 days from emergence.
- Observation In the forest-steppe zone of the Chechen Republic the critical period of weed harmfulness for the mid-season corn hybrid Zernograd 354 MV is 25 days.
- Association The longer corn and weeds grow together, the greater the yield loss.
- Association The longer corn and weeds grow together, the higher the harmfulness of the weeds.
