Effect of compost and number of cuttings on productivity of Coriandrum Sativum L. under Sinai conditions

الملخص EN

Two field experiments were carried out at El-Maghara Research Station (Middle Sinai) of the Desert Research Center (DRC), during 2014/2015 and 2015/2016 seasons, to study the effect of two doses of organic compost; 10 and 20 m3/feddan and three cuttings frequencies (without cutting, one cutting at 45 days after sowing and two successive cutting at 45 and 60 days after sowing) on the growth and essential oil content of Coriandrum sativum L.

plant grown in sandy soil.

The obtained results revealed that, the best growth parameters (plant height, number of branches, weight of 1000 seeds (g),weight of seeds per plant (g), yield of seeds (kg/feddan), oil percentage, oil yield (L/feddan), total nitrogen and carbohydrate percentages and essential oil composition were obtained by using a combination of 20 m3/feddancompost and one cutting, after 45 days after sowing, except for plant height that showed the beast results associated with “without cutting” treatment.
