Effect of spraying to growth regulator Atonik and Fe on growth ,yield and quality of carrot (Daucus carota L.) CV. Nantes

Abstract

A field study was conducted during growing season (2008 – 2009) to know the response of carrot (Daucus carota L.) CV. Nantes for spraying by growth regulator Atonik and Fe . The experiment was in RCBD factorial design with three replications. Atonik two concentrations (0 , 1) ml\L and Fe four concentrations ( 0 , 200, 400, 600) mg\L were used . The results showed that significant increases in growth yield and quality where obtained as a result of spraying Atonik and Fe .The treatment of 1ml\L Atonik gave yield 5.81 ton\don .The highest yield and root content of B .carotene resulted from interaction between Atonik treatment and Fe at concentration 600 mg\L 6.21 ton\don and 21.64 mg\gm fresh weight respectively.
