The Investigation of Corn Silage Effluent on Amaranthus retroflexus L. and Chenopodium album L. Control as Bioherbicidal

This study is conducted to investigate the utility of corn silage effluent formed by draining from the silos during silage making as a bioherbicide at the weed control. to test the efficacy as a bioherbicide, corn silage effluent and pure water is mixed in different ratios and hence six different mixtures were prepared and a two-stage experiment is conducted with these mixtures. in the first stage 10 corn seed and 50 weed seed of amaranthus retroflexus l. ve chenopodium album l. 10 mg of each mixture is applied to these seed and the ability of germination of corn and weed seeds is determined. in the second stage amount of 10 ml of each mixture is applied to the weed seeds placed in petri cups to stimulate before tillage in the fall and before seed-bed preparation in the spring and then the seed of corn were sown. bioherbicide is applied twice one after sowing before emergence and the other when the corn reached 20 cm height and then the germination and growing of the corn and weed are examined. at the and of the study the application of the mixture of pure water of 80% and corn silage effluent of 20% increased the emergence of corn at 20% and decreased the emergence of weed at 20%with respect to the application of pure water of 100%
