Effect of Compost and Titanium Dioxide Application on the Vegetative Yield and Essential Oil Composition of Coriander

Abstract

Coriander is one of the most popular and intensely used spices owing to its multipurpose uses worldwide. It is mainly cultivated for the production of its dried seed and fresh leaves. The present study aimed to evaluate the application of compost and foliar spraying of TiO2 on the yield and essential oil composition of coriander. Two field experiments were conducted during two successive seasons; after that, the yield parameters were determined, and the essential oil of the seeds was extracted and analyzed via gas chromatography-mass spectrometry (GC-MS). Results indicated that coriander growths at both years were significantly affected by compost application and foliar application of TiO2, and a significant interaction of these two factors also occurred. Compost application at 50 m3 caused significant increments of 55% and 46% in umbels number and 75% and 64% in seed yield in the first and second season, respectively, compared with control. The application of compost to the coriander plant significantly influenced oil percentage and oil yield per ha. The maximum oil percent was recorded in control plants. Foliar application of TiO2 resulted in significant improvement in plant height, number of umbels, and seed yield of coriander as compared with control and reached their maximum values at 6 g L−1 compared with the control; foliar application of TiO2 at 2 g L−1 enhanced numbers of umbels by 22% with no significant differences between 2, 4, and 6 g L−1 treatments in the first season and by 24, 33, and 48% in the second season. Increases in seed yield accounted for 34, 43, and 64% in the first season and 21, 36, and 45% in the second season due to titanium dioxide application of 2, 4, and 6 g L−1, respectively. The maximum content of linalool (87.61%) and minimum content of estragole (0.7%) was recorded at 4 g L−1 titanium dioxide with no compost.

Performance of coriander under organic and chemical nutrient management practice

“…Continuous availability and adequate supply of nutrients, including micronutrients due to compost application, may have helped achieve maximum height in compost treatment 15 besides a good physical soil condition due to the addition of organic matter to soil through compost. The results are in line with the findings of Rania et al (2022), 18 who demonstrated that compost application (50m 3 compost/ha) resulted in a significant increase in plant height and seed yield of coriander as compared with the control. These results are also in line with Vadiraj & Siddagangaiah (1998) 24 Yogesh et al (2016), 26 who reported superior growth factors of coriander under the organic nutrient management system.…”

Co-Application of TiO2 Nanoparticles and Arbuscular Mycorrhizal Fungi Improves Essential Oil Quantity and Quality of Sage (Salvia officinalis L.) in Drought Stress Conditions

“…Gohari et al [20] reported that the application of TiO 2 nanoparticles improved EO quantity and quality of Dracocephalum moldavica L. in drought conditions. Additionally, Khater et al [22] indicated that the foliar application of TiO 2 nanoparticles improved EO quality of coriander (Coriandrum sativum L.) through increasing the main EO constituents such as linalool. Shabbir et al [23] reported that the application of TiO 2 nanoparticles enhanced dry matter yield (DMY) of vetiver (Vetiveria zizanioides L. Nash) as well as physiological characteristics such as total chlorophyll content, net photosynthetic rate, intercellular CO 2 concentration, and carbonic anhydrase and nitrate reductase activity.…”

Impact of Planting Dates and Organic Fertilization on Growth, Productivity and Essential Oil Components of Coriander (Corianderum sativum L) Plant.

“…Essential oil was increased by (70.4 and 63.5%) in the first and second seasons due to the use of compost at 15 ton/fed in comparison with control plants. (Khater et al, 2021) reported that the application of compost to the coriander plant significantly influenced oil percent. The highest essential oil yield was recorded that received 50m 3 /ha an increase of 60% and 46% in oil yield.…”

“…Coriander plant (Coriandrum sativum L.) is an aromatic annual herbaceous plant belongs to Apiaceae (Umbelliferae) family which originates from Mediterranean area and Middle Eastern (Khater et al, 2021). Frequently referred to as Kazbra in Sudan and Egypt and commonly known as "Dhanya" in India.…”

“…Compost improves the physical and chemical characteristics of soil, such as soil structure, soil aggregation, porosity, hydraulic conductivity, air exchange, water holding capacity, and soil pH, in addition to its role in increasing plant output (Khater et al, 2021). Badran et al, (2018) pointed to the role of organic fertilizers in increasing the number of seeds of coriander plants.…”
