Effect of manure and foliar application of amino acids on growth characteristics, seed yield and essential oil of coriander (Coriandrum sativum L.) 777 786 64384 10.22059/ijfcs.2017.210745.654144 FA Amir Rezakhani Former M.Sc. Student, Department of Agronomy, Roudehen Branch, Islamic Azad University, Roudehen, Iran Mohammad Reza Haj Seyed Hadi Associate Professor, Department of Agronomy, Roudehen Branch, Islamic Azad University, Roudehen, Iran 0000-0002-2903-3848 Journal Article 2016 07 17 Regarding to the adverse effects of chemical fertilizers in agroecosystems, sustainable management of nutrients and non-chemical inputs are the priorities of sustainable production systems. In order to study the effects of manure and foliar application of amino acid on growth characteristics, seed yield and essential oil of coriander, an experiment was conducted at Firouzkuh, Iran in 2013. The experimental design was randomized complete blocks design with factorial arragment in three replications. The factors were manure application (0, 3, 6, 9 and 12 t/ha) and amino acid spraying (control, spraying).  Measured traits were consisted of plant height, stem diameter, leaf area index, biological yield, seed yield and essential oil content in the seeds. Results showed that the highest plant height (62.83cm) and biological yield (9281.71 kg/ha) obtained by using 9 ton manure per hectare. But, applying 12 ton manure per hectare caused maximum leaf area index (1.42), seed yield (1399.84 kg/ha) and essential oil (0.56%). Also, amino acid spraying had significant effects on all traits. Mean comparison showed that amino acid spraying caused maximum plant height (61.27 cm), leaf area index (1.28), biological yield (7693.15 kg/ha), seed yield (1110.92 kg/ha) and essential oil (0.50 %). Results of this investigation showed that applying manure and foliar application of amino acids have a important role in providing nutrients for coriander in sustainable production systems.
