In: Journal of Agricultural Research Tanta Univeristy 2004.v.30(4)Summary: An experiment was carried out on Calendula officinalis L. plants at Maryout (calcareous soil) and EL -. Sheikh Zowaid (sandy soil) locations during (2oo2/2oo3 and 2003/2004) to study the effect of plant spacing (100 and 50 cm) and nitrogen levels (0, 60, 80 and 100 kg N / fed) on the morphological characteristics ofthe plants and the physical chemical properties of the inflorescences extracts using four organic solvents (petroleum ether, n-hexane, 96 % and 80 % ethyl alcohol).The resuhs show that, the maximum values of number ofbranches, number of inflorescences, inflorescence diameter (cm), fresh and dry weight (g) per plant were obtained from the interaction between (100 cm plant spacing and 100 kg N level).Meanwhile, non significant difference Was observed between 80 and 100 kg N / levels in both locations. The maximum plant height (cm) and inflorescences yield (kg) per fed. were produced from (50 cm plant spacing and 100 kg N level) treatment.
