Abstract The aim of the present study was to determine the effects of rainfed and supplemental irrigation, and sowing period (SP) treatments on Coriander (Coriandrum sativum L.) yield, essential oil content and umbel heights by applying new agro-technologies (TDR-sensors for soil moisture (SM), GIS, Precision Agriculture, soil-hydraulic analyses and Geostatistical models) for yield and SM root zone geospatial modelling and two-dimensional GIS mapping. Results of laboratory analysis indicated a suitable soil for coriander's growth and revealed that field's soil was characterized Sandy Clay Loam(SCL) with mean values: Soil Organic Matter(SOM) = 1.70%, bulk specific gravity = 1.42 g·cm−3, Plant Available Water = 0.129 cm·cm−1, pH = 7.10 and cation-exchange capacity(CEC) = 19.3 cmol·kg−1. The two-way ANOVA statistical analysis (P = 0.05) results revealed that the irrigation treatments (IR1:rainfed, IR2:rainfed plus supplemental irrigation[best]), and the SP treatments (SP1:October's last week, SP2:November's first week[best]) significantly affects Coriander's seed yield and essential oil content, but the SP have no significant effect on plant's umbel height (P = 0.873). Supplemental irrigation, using a limited amount of water, if applied during the critical crop growth stages, can result in substantial improvement on seed yield (+284.934%), essential oil content (+125.396%) and plant's umbel height (+117.929%).

Geostatistical Models

The effects of two irrigation (IR1: rainfed; IR2: rainfed + supplemental drip irrigation), and two fertilization (Ft1, Ft2) treatments were studied on cotton yield and seed oil by applying a number of new agro-technologies such as: TDR sensors; soil moisture (SM); precision agriculture; remote-sensing NDVI (Sentinel-2 satellite sensor); soil-hydraulic analyses; geostatistical models; SM-rootzone, and modelling 2D GIS mapping. A daily soil-water-crop-atmosphere (SWCA) balance model was developed. The two-way ANOVA statistical analysis results revealed that irrigation (IR2 = best) and fertilization treatments (Ft1 = best) significantly affected yield and oil content. Supplemental irrigation, if applied during critical growth stages, could result in substantial improvement on yield (+234.12%) and oil content (+126.44%).

"The experiment was carried out in fields of Agricultural Research and Experiments Station (2) affiliated with the College of Agriculture / Al-Muthanna University during growth season 2018-2019 to study the effect of spraying three different concentrations of salicylic acid (0, 100 and 200 mg.L-1) and spray date it at three different dates (60 , 90 and 120 days after planting) on growth of Coriandrum sativum L. and a volatile oil content in seeds. The experiment was applied using a randomized complete block design RCBD with three replications. The results showed that plants treated with salicylic acid (200 mg.L-1) was significantly outperformed of dry weight shoot, the weight of 100 seeds and seed yield gave (21.76 g.plant-1, 1.22 g and 7.79 g.plant-1) respectively. While, the plants treated with salicylic (100 mg.L-1) was significantly outperformed and gave highest values of essential oil percentage (0.87%) and essential oil yield (6.32 μl.plant-1). The plants that were sprayed with salicylic after 120 days of cultivation outperformed significantly in the weight of 100 seeds, seed yield and essential oil yield were gave (1.12 gm., 7.54 gm.plant-1 and 5.53 μl.plant-1). While, the highest values were recorded in the dry weight of the shoot total (20.51 g.plant-1) and in essential oil percentage (0.787%) in plants that were sprayed after 90 days of cultivation."

Environmental contamination and the excessive use of inorganic fertilizers resulting in stagnant yields of field crops which necessitate the utilization of combined fertilization approach under changing climatic conditions. Current study was aimed to clarify the influence of several fertilizer sources (chemical, organic, organomineral fertilizers) on yield and quality of coriander (Coriandrum sativum L.). The results revealed that the fertilizer sources significantly affected the yield of coriander cultivars. The absence of “Year x Variety x Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety x Fertilizer Type” interactions were constant regardless of the year factor. The recorded values of traits according to fertilizer sources different for the plant height from 61.85 to 69.67 cm, number of branches from 5.98 to 7.71 (piece/plant), number of umbels per the main umbel from 5.62 to 7.18 pieces, seed yield from 1.06 to 1.66 t/ha, the biological yield from 4.29 to 5.70 t ha−1, harvest index from 25.29 to 29.41%, essential oil ratio from 0.29 to 0.33%, and essential oil yield from 3.1 to 5.6 L ha−1. Erbaa variety was observed to be superior over the rest of the varieties producing the maximum values of 6.5 L ha−1 of essential oil, 0.36% essential oil content, 30.9% harvest index, 1.81 t/ha seed yield, and 5.9 t ha−1 biological yield with the treatment of chemical fertilizers.

The herbal material of <em>Coriandrum sativum </em>is the fruit. Fresh herb is also used as an aromatic spice. The aim of the present study was to evaluate the content and chemical composition of coriander herb obtained at different plant growth stages. Coriander plants were grown in a glasshouse, the herb was harvested at the initial stage of flowering and from regrowing shoots. Essential oil extraction from the herb was performed by the hydrodistillation method, whereas the assessment of the chemical composition – using GC-MS method. The examined material contained 0.17–0.29 ml × 100g<sup>-1</sup> of essential oil, depending on the stage of plant development when the harvest was done. 61 (generative phase) and 65 (vegetative phase) compounds were found in the examined coriander oil. The essential oil from the coriander herb contained the highest amount of aliphatic aldehydes, among which was decanal, <em>E</em>-2-dodecanol and <em>E</em>-2-decenol had the highest percentages. The contents of most aliphatic aldehydes decreased with each subsequent harvest of the herb. In addition to the above-mentioned aliphatic aldehydes, the presence of linalool, phytol, and oleic acid was found in the essential oil extracted from the coriander herb.
