Plant growth, root yield and nutrients content of carrot as affected by the source of nitrogen and application of micronutrients

This study was carried out to give some information that could improve imported cultivars of carrot for theirnutritional status and production. In this work the effect of two N forms (ammonium nitrate and ammonium sulphate)and two levels of micronutrients, without and with (FeEDTA+MnEDTA +MnEDTA) using two imported cultivars(Nants and Kuroda) on the growth, yield and macro and micronutrients in shoots as well as in roots were studied. Theresults indicated that the plant growth and yield were affected by the source of N and application of micronutrients,whereas generally the best results were obtained with ammonium sulphate and foliar application of micronutrients. Theresponse of imported cultivars was quite similar. Macro and micronutrients in shoots as well as in roots were slightlyaffected by the genotypes, N-forms and spraying of micronutrients with unclear trend
