| Abstract | ||
| Two field experiments were carried out during 2016/2017 and 2017/2018 winter seasons at Sids Horticultural Research Farm, Egypt, to evaluate the efficacy of eleven weed control treatments on weeds and coriander productivity with monitoring chemically herbicidal residues by HPLCinbothsoil and coriander seeds in randomized complete block design with four replicates. The results show that coriander seed yield losses due to weed competition varied from 56.6-55.5 percent through the course of this study. Hand hoeing thrice, black polyethylene mulch, rice straw mulch and Stomp extra at 1.7 l/feddan treatments gave 8.95-6.90 percent of weed control accompanied with coriander increases seed yield varied from 200.9-230.5 percent than unweeded check. Such increases in seed yield per feddan are positively correlated with various studied yield components and negatively with various studied weed categories emphasizing the need of good weed control program in coriander crop production with less herbicide residues, which determined by HPLC in both soil and seed coriander were below than the maximum residue allowable level expect with Ultra afalon at 1.0 l/fed. in the soil. Economic evaluation, showed that seed yield of coriander is a profitable enterprise for coriander growers by using hand hoeing thrice or Stomp extra or black polyethylene mulch and rice straw mulch treatments which can be recommended as good and clean alternatives for weed control in coriander crop. | ||
