Abstract
In order to investigate the effects of micronutrients foliar application and irrigation intervals on black cumin, a field experiment carried out in Agricultural Research Center of Bojnord, Iran, 2009. The experiment was conducted in split plot design in a randomized complete block with 3 replications. Irrigation regime, including: I1- seven, I2- fourteen and I3- twenty-one days as main factors and sub-plots include micronutrients foliar application in five steps: M1- Non- foliar application, M2- zinc foliar application with concentrations three in thousand, M3- boron foliar application with concentrations two in thousand, M4- iron foliar application with concentrations four in thousand and M5- foliar application with a mixture of three elements. The results showed that the effect of irrigation on plant height, subsidiary branch's, number of seeds per plant, seeds per capsule, capsule number per plant, grain weight, grain yield, biological yield, harvest index, the percentage of essential oils and essential oil yield was significant. By increasing the irrigation period all of the above mentioned were decreased, except essential oils percentage that increased. Also micronutrients foliar application affected plant height, number of seeds per plant, seeds per capsule, capsule number per plant, harvest index, grain yield, biological yield, Fe, zinc and boron concentration, and the percentage of essential oils and essential oil yield. The interaction between irrigation and the micronutrients foliar application on traits, plant height, grain and biological yield and the percentage of essential oils and essential oil yield was significant. The maximum grain yield obtained by seven days irrigation regime and foliar application with a mixture of three elements interaction. And the maximum essential oils percent observed in 21 days irrigation regime and foliar application with a mixture of three elements interaction.
