| Abstract | ||||
| The present study was carried out at El-Baramoon Experimental Farm, Hort. Res. Institute, Agric. Res. Center, Ministry of Agric., during the two seasons of (2013 / 2014) and (2014 / 2015) to study the effect of sowing dates (Sept., Oct.,Nov.,Dec.and Jan.) and foliar application of some natural stimulants (Seaweeds extract, Moringa leaf extract, Salicylic acid and Chitosan) as well as their interaction on vegetative growth, fruit yield and essential oil of coriander (Coriandrum sativum L.) plant. The results showed that sowing coriander seeds in October resulted in significant increase in growth characters, fruit yield and essential oil composition compared with other sowing dates in both seasons. Foliar applications of some natural stimulants (Chitosan, followed by Moringa leaf extract then Salicylic acid) significantly affected all studied parameters compared to the treatments of seaweed extract and the control plant. Moreover, the interaction treatments indicated that the highest means values for most growth characters, fruit yield and essential oil productivity were recorded from plants sown in October and sprayed with Chitosan. Delayed sowing in December and January and spraying with Moringa leaf extract gave good production at cold temperature. The G.L.C. of essential oil revealed total of 11 compounds. The main compound was linalool which constitutes 79.8 % in October sowing date with Chitosan foliar application and the sowing date in January with Moringa leaf extract application was 78.3 %.These results showed that, it is possible to produce coriander plants under different climate conditions by using some natural stimulants. Fruits yield and active constituents under early and normal sowing dates could be improved by spraying plants with chitosan foliar application, while under delayed sowing dates spraying plants with moringa leaf extract. | ||||
