Abstract
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.
Highlights
Coriander (Coriandrum sativum L.) called Cilantro, Arab parsley, Chinese parsley, or Kasbour [1], belongs to the family of Apiaceae (Umbelliferae) [2]
An increase in seed yield occurred with increasing rainfall in the second year
Results showed that the different fertilizers had significant influences in coriander genotypes for yield, yield components, and essential oil content
Summary
Coriander (Coriandrum sativum L.) called Cilantro, Arab parsley, Chinese parsley, or Kasbour [1], belongs to the family of Apiaceae (Umbelliferae) [2]. Plant grown widely all over the world [5]. It has been cultivated for many years in several regions of Iran [6] and Turkey [7]. Coriander or cilantro are the fruit and herb of Coriandrum sativum [8] known for their special fragrance. Global coriander productivity has the largest volume as essential oil seed crops. The essential oil and its main constituent, linalool is an very significant raw material in the perfume and cosmetic products, in addition, the essential oil percent of dried fruits varies from the minimum value (0.03%) to a maximum value of 2.7% [3]. The mericarps of coriander produce an essential oil-rich in monoterpenes (volatile C10 terpenoids) which have numerous industrial applications [11]
