Abstract

Animal manure on soil prepares essential elements and increase water holding capacity and quality of plants. To study the effects of animal manure on yield and its components, nutrients absorption, chemical composition and its percentages on Cuminum cyminum this experiment was conducted at the agricultural researcher station of Zahak-Zabol, during 2003 – 2004 in a randomized complete block design with four replications. Animal manure significantly enhanced number of umbers per plant, number of seed per plant, biological and seed yield. Use of animal manure had not significant affect on Ca, Mg, Fe, P, K, Mn, Zn, and Cu and protein percentage in cumin seed but decreased Na concentration. Animal manure significantly enhanced cumin aldehyde and ρ-cymene and decrease β-pinene, γ-terpinene and α-pinene in cumin oil. A relationship or correlation exists between the main components of cumin oil. This study showed that animal manure enhances seed yield, oil percentage and qualitative chemical composition in cumin oil.
