Effect of weeding and by Forage and Medicinal plants as Companion Crops on Some of quality traits of Corn (Zea mays)

In order to study the effect of weeding and by forage and medicinal plants as companion crops on some of quality traits of corn, an experiment was conducted with corn and cover crops at Agricultural Research Station of University of Tabriz in 2011, The experimental design was randomized complete block with 3 replications and 10 treatments. The treatments included synchronic cultivation of clover and corn, clover cultivation 15 days after corn cultivation, synchronic cultivation of hairy vetch and corn, hairy vetch cultivation 15 days after corn cultivation, cultivation of basil and corn, basil cultivation 15 days after corn cultivation, synchronic cultivation of dill and corn, dill cultivation 15 days after corn cultivation, corn with weeding, corn with weeding and weedy plots. The 8 treatments of these 10 treatments were based on a 4×2 factorial randomized complete block form, four types were and by forage and medicinal plants as companion crops (clover, hairy vetch, basil and dill) and two cultivation time (synchronic cultivation and cultivation 15 days after). It has been shown that the corn weed control, treatment has oil present, protein present, fiber present and starch present to other treatments. Among companion crops, the cultivation of clover with corn had highest amount in all traits compared to other treatments. Also, synchronic cultivation companion crops with corn relation to cultivation 15 days after corn cultivation all traits had a high remain.
