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 × Variety × Fertilizer Type” interactions for any of the noted parameters signaled that the detected “Variety × 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−1, 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.

Poor soil organic content is a major cause of declining crop productivity in developing countries. Less precipitation and high temperatures oxidize organic matter in the soils of semi-arid regions. Such a deficiency in the organic matter of the soils decreases the bioavailability of many nutrients. Organic amendments like vermicompost (VM) have the potential to overcome this problem, while decreasing the dependency on inorganic fertilizers. Thus, the aim of our study was to explore the best application rate of VM for the improvement of nutrient contents in buckwheat. We used two buckwheat cultivars i.e., Aktaş and Güneş were sown under variable rates of soil-applied VM (0, 0.75, 1.50, 2.25 and 3.00 t ha−1) in semi-arid highland conditions. The results demonstrated that the nutritional quality parameters were improved when VM was applied at the rate of 2.25 t ha−1. In addition, VM at 2.25 t ha−1 resulted in an improvement of the N and P contents of the grains. The P contents in the grains of the Güneş variety was higher (0.26%) than the Aktaş variety (0.24%). A significant improvement in Fe (%), Cu (%), Zn (%) and Mn contents (%) in the grains of buckwheat validated the efficacious functioning of 2.25 t ha−1 of VM. The Zn content of the grains was higher in the Güneş variety (34.06%) than the Aktaş variety (31.96%). However, no significant change in K, Ca and Mg was noted at any level of VM in both Aktaş and Güneş. It is concluded that a 2.25 t ha−1 VM application in the buckwheat crop under zero conventional fertilizer was the best level to boost the nutritional quality of the grains.

Soil pollution is a global concern from past to recent. Toxic and high resistance nature of chemical pollutants, such as heavy metals show their important as environmental risk and a serious problem for human health, because they can introduce to the food chain from contaminated environments. Experiments were conducted to evaluate the effect of Cd, Cu, Pb, and Zn on qualitative parameters of dill (Anethum graveolens L.), and basil (Ocimum basilicum L.) grown in polluted soil environment. Heavy metals concentration, total phenol and flavonoid, essential oil percentage, DPPH radical scavenging activity, super and nitric oxide radical scavenging activity in leave and stem parts of the plants were analysed in this study according to standard methods. According to results, Cu was the dominant heavy metal in leave and stem of both studied plants, followed by Pb, Zn, and Cd. The concentration of various heavy metals in dill was more than two times higher than basil. Total phenol and flavonoids showed significant differences in leave and stem in both plants. DPPH, super oxide and nitric oxide radical scavenging activity showed significant higher values in leave than stem in both plants.

Heavy metals are important environmental pollutants and can affect the lives of plants and subsequently the lives of humans and other organisms. On the other hand, medicinal plants and their polyphenolic constituents have received much attention due to their confirmed positive effects on human health. Therefore, in this study, the effect of heavy metal lead, one of the most important toxic metals in the environment, on the polyphenolic compounds of the basil medicinal plant (Ocimum basilicum L.) was investigated. The purpose of this study was to evaluate the resistance of this medicinal plant to stress induced by lead toxic metal and also the content of polyphenolic compounds. The method was planted in basil greenhouse and factorial experiment in a completely randomized design with three replications. Lead metal treatment with 0, 25, 50 and 75 ppm levels, EDTA treatment with 0 and 1 mmol L-1 and humic acid treatment with 0 and 2 kg ha-1 were applied. After harvesting at flowering stage, the hydroalcoholic extract of dry shoots was prepared and the amount of polyphenolic compounds in the extracts was measured. The results showed that lead in soil significantly changed the content of polyphenolic compounds of basil. Increasing the amount of lead metal generally decreased the polyphenolic compounds of the plant. The presence of EDTA also increased polyphenolic compounds and reduced the content of polyphenolic compounds using humic acid.Keywords: Antioxidant, EDTA, Humic acid, LeadDOI: 10.7176/JSTR/5-12-06
