To evaluate the effect of foliar application of nano iron chelate and iron chelate fertilizers on morphological traits and essential oil content of holy basil, an experiment was conducted at research farm of Department of Horticultural, Shahid Chamran University of Ahvaz based on randomized complete blocks design with six treatments and three replications. The treatments were including control, nano iron chelate (0.5, 1 and 1.5 g/l) and iron chelate (1 and 1.5 g/l) fertilizers. Foliar application of fertilizers was done at six to eight leaves stage and was repeated with 15 days interval until the end of the study. Intended traits were measured at full bloom stage. The results showed that the effect of foliar application of iron fertilizers on morphological traits such as plant height, axillaries shoots, leaf number, leaf area, fresh and dry weights of leaf and aerial parts and essential oil content of holy basil were significant. The highest and lowest values of mentioned traits were obtained in plants sprayed with 1 g/lnano iron chelate and control, respectively. Overall, regarding to non-significant difference between 1 and 1.5 g/lnano iron chelate and 1.5 g/liron chelate treatments, for increasing mentioned traits of holy basil, foliar application of nano iron chelate with 1g/l is recommended.

Spearmint (Mentha spicata L.) is one of the most important mint family plants that has numerous applications in food, cosmetical, and pharmaceutical industries due to its valuable medicinal properties. In this research, the change in plant fresh and leaf dry weights, essential oil content, yield and composition during year as randomized complete block design with twelve treatments and three replications was studied. Result showed that harvest time had a significant effect on plant fresh and leaf dry weights, essential oil content and yield. The highest plant fresh (1868.7 gr.m-1) and leaf dry (253.3 gr.m-1) weigths were recorded on July and June, respectively. Plants also showed highest amount of essential oil content (3.82%) and yield (8.5 gr.m-1) on July. The main essential oil componenens were carvone, limonene, careen, α-pinene, myrecene, β-borbonene, cisdihydrocarvone, dihydrocarveol, dihydrocarvyl acetate, Pulgone and trans caryophylene. The highest (67.9%) and lowest (22.4%) amounts of carvone were observed on July and January, respectively. The highest (21.1%) and lowest (4%) amounts of limonene were observed on augest and December, respectively. The maximum amount of caren (5.8%) was obtained on January. Cis dihydrocarvone, dihidrocarveol and dihydrocarvyl acetate were increased during winter. In total, spearmint can harvested from May to October but best harvesting time is July.
