Effect of Mineral NPK and Organic Fertilization on Growth, Yield, Essential Oil and Chemical Composition of Coriander Plants

Abstract

to study the effect of mineral NPK and organic fertilization on growth, yield, essential oil and herb N, P and K % of Coriandrum sativum, L. plants. The obtained results revealed that all studied characters of growth, yield, essential oil and herb % of NPK were significantly augmented due to the use of both low and high NPK fertilization rates with the high one giving the highest values. Concerning organic fertilization, the different growth traits (plant height, stem diameter and herb dry weight), yield and yield component characters (number of umbels/plant and fruit yield per plant and per fed), essential oil parameters (percent and yield per plant and per fed) and NPK % in the herb were gradually increased parallel to the gradual increase in compost level. The combined treatment between the low NPK rate (50 g kristalon/10.8 m 2 plot)and medium compost level (10 ton/fed) resulted in better fruit and essential oil yield than that obtained from the high NPK rate. So, the possibility of substituting one half of the mineral NPK dose by the medium compost level is justified.

Effect of Fertilization and Foliar Applicaion Treatments on Coriander Plant (Coriandrum sativum L.)

“…This trend was found under both studied seasons. A similar result was obtained by Badran et al (2018) and Al-Hatem (2018). Table (4) indicate the values of weight of 1000 seeds (g) and fruit yield (g plant -1 and Kg fad -1 ) of coriander plant as affected by the different types of organic fertilizers, different foliar applications and their interactions during the seasons of (2015/ 2016) and (2016/ 2017).…”

“…Also, the both organic fertilizer treatments (CP and FYM), the best foliar treatment for all the aforementioned traits was obtained with (Humic acid +seaweed), following in descending order with (bio-fertilizer +seaweeds), (bio-fertilizer + Humic acid), bio-fertilizer alone, seaweeds extract alone, and lastly Humic acid alone This trend was found under both studied seasons. A similar result was obtained by Badran et al (2018) and Al-Hatem (2018). Table 4.…”

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

“…And these differences in essential oils may result from a variety of factors, including climate circumstances, growing conditions and species (Ghobadi and Ghobadi, 2012) reported on coriander essential oil should contain linalool in excess of 50% to 70%. Badran et al (2018) showed that increase in compost level was associated by a gradual and consistent increase in each of essential oil percent and yield per 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.…”

“…This increase may result from an increased uptake of essential nutrients by the plant. Composting enhances the structure of the soil and makes it easier to cultivate when combined with conventional NPK fertilizer, encouraging roots growth and providing them with nutrients and enabling plants to increase their uptake (Rashed and Darwesh, 2015).Moreover, Compost helps absorb water and retain it in the soil (lea Master et al, 1998).And showed that vegetative growth traits, plant height and herb dry weight per plant of coriander plants increase significantly due to fertilizer application and the highest values being obtained due to the higher level of compost (Badran et al, 2018 andAbdallah, 2009) The maximum values were detected at the middle sowing date on 1 th November while the lowest values were detected at the late sowing date on 15 th of November. These effects may be due to optimum temperature and a longer photoperiod reaching the crop during its growth period at the early sowing date which can give plants an opportunity to build up more stored foods compared to later sowing dates and this may be reflected in faster growth for plants.…”

“…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. On another hand, chemical fertilizers are used with the compost because they contain a lot of nutrients and that plants can quickly absorb them (Kadhim, 2021).…”
