Corn-white Clover Intercropping in Terms of Herbicide Tolerance of White Clover

The paper evaluated corn white clover intercropping in terms of herbicide tolerance of white clover, methods of reducing weed competition, nitrogen potential reduction due to the presence of clover, and regeneration potential of clover without replanting. The white clover was sown by using a no-till seeder, which sown 4 kg of seeds per hectare without inoculating seeds or chemically correcting the soil. The weeds were manually control until corn is fallow. The results show that nitrogen, as a condiment for the intercropping system of corn and clover, can increase the plant height of corn, the number of grains per row, the weight of grains per thousand and the weight of thousand grains. These parameters are optimized when the clover is suppressed by the herbicide. In the evaluated clover herbicide management strategy, the continuous application of glyphosate treatment 21 days before and 15 days after corn planting produced the best clover suppression and highest corn yield.
